A first aspect of an embodiment of the present application provides a control method for an application in a cluster.

In the embodiment of the present application, the control method may include the following. For any cluster, the following is performed. Note that the following description is given taking a certain cluster as an example, and the following description can be executed regardless of the number of clusters. Judging whether the cluster needs to execute a control operation aiming at the current application, wherein the control operation is any one of the following operations: deploying a current application, updating the current application, and rolling back the current application. The current application is an application that needs to perform a control operation, for example, the current application may be a latest application of a latest version number of a certain application, or may be a preset rollback application of a certain version that needs to rollback, or an application of a certain version number (not necessarily the latest version number) that is set to need to be deployed, and the current application may carry identification information (for example, a name) and a version number. For example, the current application is the latest application of the latest version number of a certain application, and the control operation is to update the current application. For any cluster, judging whether an old version application is deployed before the cluster, wherein the old version application and the latest application are the same application, but the version number of the old version application is lower than that of the latest application; judging whether the cluster needs to execute updating of the current application aiming at the current application by judging whether the old version of application is deployed before the cluster; if the old version of application is deployed before, the current application needs to be updated according to the current application; if the old version of the application has not been deployed before, the current application does not need to be updated according to the current application. For another example, the current application is a latest application with a latest version number of a certain application, and the control operation is to deploy the current application. Presetting which clusters are deployed aiming at the current application, and establishing a cluster deployment list; for any cluster, judging whether the current application needs to be deployed aiming at the current application by judging whether the cluster is in a cluster deployment list or not; if the current application is required to be deployed in the cluster deployment list, the current application is required to be deployed aiming at the current application; if the current application is not deployed in the cluster deployment list, the current application does not need to be deployed aiming at the current application. Or judging whether the cluster needs to execute deployment of the current application aiming at the current application by judging whether the old version application is deployed before the cluster; if the old version application is deployed before, the current application does not need to be deployed aiming at the current application; if the old version of the application has not been deployed before, the current application needs to be deployed according to the current application. For another example, the current application is a rollback application and the control operation is to rollback the current application. Presetting which clusters are backed for the current application, and establishing a cluster backspacing list; for any cluster, judging whether the current application needs to be executed and backed for the current application by judging whether the cluster is in a cluster rollback list or not; if the current application is in the cluster rollback list, the current application needs to be rolled back aiming at the current application; if not, the current application does not need to be rolled back for the current application. And under the condition that the cluster needs to execute the control operation aiming at the current application, judging whether an operation threshold value is met, wherein the operation threshold value is a threshold value corresponding to the cluster executing the control operation aiming at the current application. It should be noted that the operation threshold may be determined according to specific situations, and may be for any cluster, regardless of which operation is executed for any current application, the operation threshold corresponds to the same threshold; different operations can be executed for different current applications for any cluster, and the different operations correspond to different thresholds; the same operation can be executed for any cluster aiming at different current applications, and the same operation corresponds to the same threshold value; etc., as the case may be. In addition, in the embodiment of the present application, the operation threshold may be a default threshold or a currently configured threshold. And sending a control instruction for controlling the cluster to execute the control operation aiming at the current application under the condition that the operation threshold is met, so that the cluster executes the control operation aiming at the current application.

By the technical scheme, whether control operation needs to be executed aiming at the application or not is judged for any cluster, whether an operation threshold value is met or not is judged under the condition that the control operation needs to be executed, and a control instruction is sent under the condition that the operation threshold value is met, so that the cluster executes the control operation aiming at the application.

Fig. 1 schematically shows a flowchart of a control method for an application in a cluster according to an embodiment of the present application. As shown in fig. 1, in an embodiment of the present application, a control method for an application in a cluster is provided, which includes the following steps. The following is an example of a certain cluster, and the following may be performed regardless of the number of clusters.

In step S10, it is determined whether the cluster needs to perform a control operation for the current application, where the control operation is any one of the following: deploying the current application, updating the current application, and rolling back the current application. If yes, executing step S11; if not, step S13 is executed.

In step S11, it is determined whether an operation threshold is satisfied, where the operation threshold is a threshold corresponding to the cluster executing the control operation for the current application. If the operation threshold is met, executing the step S12; if the operation threshold is not full, step S11 is repeatedly executed. Alternatively, when the operation threshold is not satisfied and it is determined again whether the operation threshold is satisfied, it may be determined again whether the operation threshold is satisfied at preset time intervals, where the preset time intervals may be determined according to specific situations.

In step S12, a control instruction is sent to control the cluster to perform a control operation for the current application, so that the cluster performs the control operation for the current application.

Optionally, in this embodiment of the present application, the control method may further include the following. Under the condition that the operation threshold value is not met, judging whether the operation threshold value is met again at preset time intervals until the operation threshold value is met; and/or giving an alarm prompt when the operation threshold is not met and the preset operation time limit is exceeded. Specifically, the operation threshold may be determined again at a preset time interval or immediately determined again when the operation threshold is not satisfied, and the alarm prompt may be performed when the operation threshold is not satisfied even after the preset operation time limit has been exceeded. For example, the related prompt content is displayed on the interface.

Optionally, in this embodiment of the present application, the operation threshold is related to a priority of the cluster. Specifically, for the same current application and the same control operation, the operation threshold is set according to the priority of the cluster, so that when a plurality of clusters execute control operation for the current application, different clusters have a precedence order, and service interruption caused by the fact that all clusters simultaneously execute control operation for the current application is avoided.

Optionally, in this embodiment of the present application, before determining whether the operation threshold is met, the control method further includes the following. It is determined whether a determination of whether an operational threshold is satisfied. For example, it may be preset as to whether it is necessary to determine whether the operation threshold is satisfied. For example, the setting need not determine whether the operational threshold is met in a more urgent situation. And judging whether the operation threshold is met or not according to a preset condition. And directly sending a control instruction under the condition that whether the operation threshold is met or not is not required to be judged. In this way, efficiency can be improved in special cases.

Fig. 2 to fig. 4 relate to how to perform deployment application, update application, and rollback application, respectively, and the control method provided in the embodiment of the present application is exemplarily described below with reference to fig. 2 to fig. 4. Wherein the following description is in a multi-cluster environment. In the embodiment of the application, in a multi-cluster environment, different operation thresholds can be set for each cluster, so that differentiated management is performed on version control of the application, and therefore, in the multi-cluster environment, the application can automatically perform version control operations such as deployment, update, rollback and the like in batches by taking a single cluster as granularity according to a preset strategy. The technical scheme provided by the embodiment of the application mainly comprises the following steps: 1) In a multi-cluster environment, carrying out application version control on the whole system and related components in batches according to a preset threshold value of each cluster; 2) Logic and processing flow when application version management is performed on multiple clusters.

An exemplary description of a deployment application is provided in connection with fig. 2. Any application may be deployed for any cluster with reference to the following.

And judging whether the deployment is needed. If yes, judging whether to carry out condition check; if not, deployment is completed, and the method is finished. When an application needs to be deployed to a cluster which is not deployed before, an operator is required to manually submit an application deployment request to the version control manager at a front-end page. When a certain application is deployed, a cluster which needs to be deployed needs to be selected to obtain a deployment cluster list and submit necessary information such as the name and version of the application which needs to be deployed. And judging whether the cluster needs to deploy the application or not according to whether the cluster belongs to a deployment cluster list or not.

And judging whether to perform condition check. If so, judging whether the conditions are configured independently; and if not, sending a deployment instruction to the cluster controller. Wherein the condition check is to determine whether the operation threshold is satisfied. When an application is deployed in a cluster, a checkbox is used to select whether the deployment skips a condition or threshold checking step. If the check is skipped, a deployment command is sent directly to the cluster controller, which is typically only used in case of emergency on-line. The cluster controller is a module for controlling the cluster to operate, and is responsible for uniformly managing resources such as a host, a virtual machine, a container cluster and the like in the cluster, and the main functions of the cluster controller include but are not limited to startup and shutdown, application start-stop deployment deletion, database addition, deletion, modification and check and the like.

It is determined whether conditions are configured separately. If yes, configuring conditions; if not, executing the check condition. When an application is deployed in a cluster, a default preset condition (where the condition is an operation threshold) corresponding to the cluster may be selected for use, and the condition may be configured separately, for example, for the latest application. The condition of the individual configuration overrides the condition of the default configuration of this cluster to which this application applies.

Configuring conditions, namely not using default preset conditions, and performing condition configuration independently. After the condition is configured, the condition is checked, that is, the content in the condition corresponding to the cluster is obtained. For example, the condition is that "other clusters have been running for 24 hours and no service error log", and the checking condition is to check whether other clusters have been running; what, if any, the runtime is; whether there is an error log.

And judging whether the cluster meets a threshold value for deployment operation. That is, it is determined whether the content acquired by the check condition section satisfies a default preset condition or an individually configured condition. If the judgment result is that the threshold is not met temporarily, performing condition check again after a certain silent time (preset time interval) and judging whether the threshold is met; if the judgment result is that the threshold is met, sending a deployment command to the cluster controller; if the set normal deployment time limit (preset operation time limit, wherein the timing starting point is "judging whether deployment is needed") is exceeded and the deployment threshold is not met yet, prompting is carried out on a front-end interface, and checking conditions and threshold judgment are continuously carried out at regular intervals (preset time intervals) until the deployment instruction is sent according to the threshold or the deployment is manually cancelled on a front-end page.

And ending the application deployment operation of the cluster. In the deployment process, data such as application information, cluster information, current steps, execution results and the like are recorded in a database at each step for query, display and other operation bases. The application information mainly comprises an application name, a version, an application ID, a code branch ID (optional) and construction time (optional); the cluster information includes cluster name, cluster ID, cluster location, cluster usage (test, online, large client, etc.), IP and port used by the cluster controller, etc. For the application information, since part of the software is third-party software which is not built by itself, part of the software information may not exist. The cluster information and the application information exist in separate database tables, and other related information is obtained by recording the application ID and the cluster ID and performing related query with other database tables.

An exemplary update application is described in connection with fig. 3. The following can be referred to when updating any application for any cluster. After a latest application is submitted to the material warehouse (module for storing the application), the material warehouse informs the version management controller of application update by calling a rear-end Webhook interface of the version management controller.

It is determined whether the cluster needs to be updated for the latest application. If yes, performing condition check; if not, the updating is finished, and the method is finished. Specifically, the version management controller determines whether the managed cluster needs to update the latest application according to a preset condition for determining whether the cluster performs updating. If the cluster does not need to be updated (for example, a low-version application corresponding to the latest application is not installed before, an application of a current version corresponding to the latest application installed by other applications depending on the cluster, an upgrade check box is manually checked off (no update is selected)), and the like), the upgrading process is directly ended; otherwise, entering an updating step.

Judging whether condition checking is carried out or not, if so, judging whether conditions are configured independently or not; if not, an updating instruction is sent to the cluster controller. When the latest application is deployed in the cluster, a check box is used for selecting whether the current deployment skips the threshold checking step. If the check box is checked during updating, an updating command is directly sent to the cluster controller without checking and judging the threshold, and the operation is only used for emergency online generally. If the skip condition check determining step is not explicitly stated, it is determined whether the condition is separately configured.

Subsequent steps may refer to those related to the description of deploying an application in connection with fig. 2 above. It is determined whether the cluster satisfies a threshold for performing an update operation (operation threshold). If the judgment result is that the updating threshold value is not met temporarily, the condition is checked again after a certain time (preset time interval) and whether the updating threshold value is met or not is judged; if the judgment result is that the threshold value is met, sending an updating command to the cluster controller; if the maximum allowable time (preset operation time limit) is exceeded and the updated threshold value is not met, prompting is carried out on a front-end interface, and checking conditions and threshold value judgment are continuously carried out at regular intervals (preset time intervals) until the updating instruction is sent or the deployment is manually cancelled.

And ending the updating of the application of the cluster. In the updating process, data such as application information, cluster information, current step, execution result and the like are recorded in a database at each step for query, display and other operation bases.

FIG. 4 illustrates an exemplary illustration of logic for a fallback application. The following explanation applies to any application rolling back for any cluster.

The general process of the rollback application is similar to the update application, and the differences mainly lie in the following points, and other processes are not described again: 1) An operator can operate at a front-end console of the version management controller, designate a rollback application (specifically designate an application which needs to be rolled back and a version number thereof) and a cluster which needs to be rolled back, wherein the judgment of 'whether the rollback is needed' can be carried out according to designated contents; 2) An old version list and a rollback cluster list of the application are required to be inquired from a database for business personnel to select so as to specify the rollback application and the cluster required to be rolled back, and for an application version part, a once deployed version can be preferentially displayed; 3) Compared with an operator who inputs cluster information and a threshold value, the operator who designates the rollback application and the cluster which needs to be rolled back has higher operation authority, and application abnormity caused by misoperation is prevented. Specifically, an operator can forcibly designate skipping condition check on a front-end console page when an application is updated or backed, so that the version of the designated application in the multiple clusters is quickly modified for emergency updating or backing, and the operation also requires that the operator has higher operation authority than the operator who inputs cluster information and a threshold value, so that the situation that the unauthorized new version of the application is released to an important cluster due to misoperation is prevented. In addition, although fig. 4 does not show the "judging whether to configure the condition separately", this step may be performed when the application is rolled back.

The following takes a version management controller managing two clusters (cluster a and cluster B) as an example, and exemplarily introduces the technical solution provided by the embodiment of the present application.

1) The operator inputs the operation threshold corresponding to each cluster into the front-end console of the version control manager. In this example, it is assumed that the operation threshold of the cluster a is not set (i.e., the operation threshold is checked but is not passed unconditionally), and the operation threshold corresponding to the cluster B is set to have other clusters run the new version application for 24 hours and have no service error log. And the front-end console is compiled by using NodeJS and is mainly responsible for storing cluster data and an operation threshold value input by an operator into a database and reading and displaying an upgrading task result from the database.

2) The front end console stores the data in a database. The database uses MySQL and is mainly used for storing cluster information, application information and change records each time. The cluster-related information mainly includes cluster information of each managed cluster, information of a cluster controller (e.g., ip, port, and the like), information of applications running in the cluster, an operation threshold for deployment of each application, and a deployment result. The database software is not in the scope of the technical solution provided by the embodiments of the present application, but the content of the database is a part of the technical solution provided by the embodiments of the present application. The change record mainly comprises change starting time, time and result of each check, and operation content, time and result, change result and completion time are sent to the cluster controller; the operation comprises deployment, updating, rollback and the like, and the change result is successful or cancelled. Furthermore, the information of the applications running in the cluster is used to explain which cluster has installed which application or applications.

3) The new version application (the latest application) is submitted to the material warehouse. Wherein a certain latest application corresponds to a latest version of a certain application.

4) And after receiving the new version application, the material warehouse sends update information to an update controller of the version control manager through Webhook. The update controller is written using Python, and has the main functions of receiving application update information, reading information and update threshold (corresponding operation threshold for updating), detecting update conditions, sending update commands to the cluster controller, and collecting update results. For the application updating information, when the application warehouse receives a new version of application, the application warehouse can retrieve the previous application information (name, version number and the like), submit the application information to the application version controller and update the database record for the application version controller; the reading of the nano-management cluster information is to obtain the previously described cluster information (mainly descriptive information such as name, location, etc.) from the cluster controller of the target cluster.

5) After receiving the update information of the application sent by the material warehouse through WebHook, the update controller queries the clusters to be updated of the application and the threshold information (operation threshold) corresponding to the update application of each cluster from the database. When a new version of application is received, an update operation on clusters in which an old version of application is installed is directly triggered, and then which clusters install the old version of application corresponding to the same application as the latest version of application and update thresholds (operation thresholds corresponding to the updated application) of the clusters can be queried from the database.

6) The updating controller obtains the clusters needing to update the new version application as a cluster A and a cluster B through inquiry, and the update threshold of the cluster A is the update threshold of the cluster B, and the update threshold of the cluster B is the service error log which needs other clusters to run the new version application for 24 hours. After the current environment is judged, the current cluster A meets the updating condition, but the current cluster B does not meet the updating condition, and then an updating command is sent to the cluster controller of the cluster A.

7) And after receiving the updating command, the cluster controller of the cluster A reads the new version application from the material warehouse. The cluster controller is composed of a series of Shell and Python scripts, is mainly responsible for life cycle management of applications in the cluster, and can support life cycle management of applications on various platforms such as bare metal, physical machines, virtual machines and containers. The tools used by the cluster controller are outside the scope of this application.

8) And after the cluster controller receives the new version application, upgrading the application in the cluster.

9) And after the application is started, logging the log into a log center of the cluster. The log center uses a log platform built based on the ELK, and is out of the scope of the application.

10 "update controller" component of "version control manager" reads the update result of the application from the log center of cluster a for conditional judgment of subsequent other cluster upgrades.

11 Because the update threshold of cluster B is "there are no service error logs for 24 hours when other clusters have run the new version application", the current environment does not satisfy the condition, and therefore, the update command is not sent to the cluster controller of cluster B for the time being.

12 Within 24 hours of the cluster a updating application, the updating controller will judge again at regular intervals whether the updating threshold of the cluster B is satisfied, the quiet time of the retry check condition of the updating controller is set to be "1 minute to 1 hour", and is set to be "for any cluster needing updating application, check once every minute within 5 minutes (including 5 minutes, the latter case is similar) whether the updating threshold is satisfied, check once every 5 minutes within 5 to 20 minutes, check once every 10 minutes within 20 to 60 minutes, check once every 60 minutes after 60 minutes", so as to avoid checking that resources are consumed too frequently or the checking interval is too long, which results in updating lag. After cluster A updates application for 24 hours, the update controller checks the update condition of cluster B again, finds that the condition is met, that 'other existing clusters run the new version for 24 hours', and applies error-free logs by inquiring the log center of cluster A, so that the update threshold of upgrading the application in cluster B is met. And then the update controller sends an update command to the cluster controller of the cluster B, and the following process is the same as steps 7) to 9), which is not described again. And finishing the updating of the clusters A and B, and finishing the updating in the round.

In the embodiment of the application, the method and the device are used for judging the operation threshold preset by the cluster when the application is deployed, updated and backed up by acquiring and processing various information in the plurality of clusters. The classification according to the type of the collected information can be divided into the following three categories, that is, the content in the operation threshold mainly includes the following three aspects (time of event occurrence, number of event occurrences and application performance). 1) And (4) time stamping. The timestamp is used for recording the occurrence time of various events, such as the time of submitting a new version application to a material warehouse, the time of performing operations such as deployment and update on the application in each cluster, the time of operating each cluster by a version control manager, and the like, and the information can simultaneously record corresponding operation contents. Time-related settings such as "application has been submitted to the material warehouse for XX hours", "there has been other cluster updates for XX hours", etc. are supported when setting the operation threshold for a cluster. 2) A counter. The counter is used for recording the times of occurrence of specified events, such as the times of processing requests of the application, the times of error reporting of the application, the times of abnormity (deadlock, quitting and the like) of the application and the like. And when the operation threshold value is set for the cluster, the settings related to the times, such as the number of application response times, the number of application error reporting times, the number of application abnormal times and the like, are supported. 3) And (5) summarizing. The abstract is used for recording the performance of the application, such as performance related indexes of average CPU (central processing unit) occupation, average memory occupation, average interface response time and the like. And when the operation threshold value is set for the cluster, performance indexes such as CPU occupancy rate change, memory occupancy rate change, response time change and the like are supported. Further, the operation threshold setting is dependent on the priority of the clusters to control the operation in batches in the case of multiple clusters.

The collection frequency of two monitoring types of the counter and the abstract is once collected every minute, old data before one day can be recalculated by taking ten minutes as a unit, old data before three days can be recalculated by taking days as a unit, and the pressure of numerical calculation and storage is reduced as much as possible on the premise of ensuring the accuracy of recent thermal data. And the two types of data have a correlation relationship with the application version, and as the application version in a cluster changes, the two types of data in the cluster are subjected to statistical calculation again and are compared with the data before the application changes. The summary data only retains the information of 90% quantile, and ignores the data jitter caused by the emergency.

In the prior art, canary deployment exists. Canary deployment: the changes are generalized to a small fraction of users for testing before being generalized to the entire service cluster and made available to all. And continuously observing the state of each dimensionality of the tested service in the testing process, and verifying the robustness, the availability, the stability and the like of the new version.

According to the technical scheme provided by the embodiment of the application, different thresholds can be set for each cluster in advance according to the dimensions such as the application and the importance degree of each cluster. When the controller detects that the application has an update, the controller judges the threshold values of all the managed clusters, and sends instructions such as deployment or update to the controller of the cluster only when the set threshold value is reached.

After the threshold value is set for the cluster, other steps of application deployment, updating or rollback do not need manual intervention if no special condition exists, and therefore automatic batch deployment, updating or rollback and other operations of the application in a multi-cluster environment are achieved. If the application is found to be abnormal in the operation process of a certain cluster, the cluster with the lower threshold value can be operated, so that the influence is controlled to the cluster with the lower importance as much as possible, and the influence on the whole service caused by the operation of all the clusters is avoided. Meanwhile, the management control of the application on a plurality of platforms such as bare metal, physical machines, virtual machines, containers and the like can be supported by depending on the abstraction of the lower-layer application on the application running platform.

Compared with the prior art, the technical scheme provided by the embodiment of the application can conditionally control the application version in a multi-cluster environment. In addition, according to the technical scheme provided by the embodiment of the application, the influence possibly caused by application abnormity can be controlled in a smaller range as much as possible by automatically judging the operation threshold, meanwhile, the possibility of errors in manual management of multiple clusters is greatly reduced, and the overall stability of application is improved.
