Description
Technical Field
The application relates to the field of cloud computing, in particular to a multi-cluster migration method and device for application containers.
Background
As applications on the cloud increase, application service scales become larger, application containers become larger, and host resources required increase. The host computer node scale on the cluster can cause greater and greater pressure on the performance of the cluster management component, and when the node reaches a certain scale, the cluster management component can run abnormally, so that the host computer node scale which can be managed by the cluster on each cloud is limited. Because of the performance bottleneck of cluster management software, single cluster host nodes have upper limit, and one cluster can manage 1000 host nodes at maximum. After the cluster reaches the upper limit of the scale, a new cluster needs to be built to meet the demands on host resources. After a new cluster is built, the part of the containers that need to be applied are migrated from the old cluster to the new cluster. Since the cluster management component version upgrades, the old cluster version cannot meet the application requirements, the application container needs to use the new version cluster, and at this time, the application container needs to be migrated from the old cluster to the new cluster.
Because cloud computing technology updates and iterates very fast, the version of the cluster management component is updated frequently, so that old clusters need to be offline, and new clusters are added. For cloud application and business rapid expansion of large companies, the cluster scale rapidly expands. Cluster management technology updates and cluster scale expansion are two main factors that lead to application container migration, and two factors lead to frequent migration of cloud-up application containers to meet the demands. For the cloud computing cluster management platform, the old clusters can be disconnected after all the containers deployed on the clusters are stopped, the process depends on the migration speed of the application containers, cluster resources cannot be recovered in time, and the process consumes time and server resources.
The inventors have found that prior art container deployment approaches require a user to specify the deployment cluster and the number of container copies. When an application performs container migration, new cluster information needs to be acquired, a container deployed cluster is modified to be a new cluster, then a previously deployed container is killed on an old cluster, and then the container is started on the new cluster. The scheme is opaque to the application, so that the application needs to frequently modify the cluster and restart the container in the process of frequently migrating the cluster, the operation flow is complex, and the user experience is not friendly. After all containers deployed on the old cluster are stopped, the cluster management platform can be used for offline of the old cluster, so that the cluster management platform and the application are mutually dependent, and decoupling of the cluster management and application deployment container modules cannot be achieved.
Therefore, how to provide a new solution to the above technical problems is a technical problem to be solved in the art.

Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Considering that the container deployment approach in the prior art requires a user to specify the deployment cluster and the number of container copies. When an application performs container migration, new cluster information needs to be acquired, a container deployed cluster is modified to be a new cluster, then a previously deployed container is killed on an old cluster, and then the container is started on the new cluster. The scheme is opaque to the application, so that the application needs to frequently modify the cluster and restart the container in the process of frequently migrating the cluster, the operation flow is complex, and the user experience is not friendly. After all containers deployed on an old cluster are stopped, the cluster management platform can be used for downloading the old cluster, so that the problem that cluster management platform and application are mutually dependent and decoupling of cluster management and application deployment container modules cannot be achieved is solved. And monitoring whether the states of all member clusters change, and executing corresponding cluster migration operation according to the change characteristics of the states of the member clusters after the states of the member clusters are monitored, so that when the clusters are deployed by application, the clusters needing to be deployed are not required to be designated, the cluster information needing to be deployed is not required to be acquired, and meanwhile, when a new cluster is online or an old cluster is offline, the deployment and migration work of an application container in multiple clusters can be accurately, automatically and unintelligly completed.
In order to flexibly implement deployment and migration of application containers in multiple clusters, the application provides an embodiment of an application container multiple cluster migration method, referring to fig. 1, where the application container multiple cluster migration method specifically includes the following contents:
step S101: and receiving an application container deployment instruction sent by the federal cluster management platform, and executing corresponding application container deployment operation according to the total number of application deployment copies in the application container deployment instruction and a cluster scheduling strategy.
It may be understood that, the execution body of the technical solution of the present application may be a federal cluster, specifically, a cluster federal management control component kubuffed is installed and deployed on a certain cluster, the component is used to manage a federal cluster, a join command of a control panel of the federal cluster is used to add the cluster to the federal cluster, when the cluster exits, the cluster may be deleted from the federal cluster by an unjoin command, a control panel kubuffed of the federal cluster is installed, and the objective of the cluster of the component is to implement a mechanism that a single cluster manages multiple clusters uniformly, and multiple clusters may be deployed and operated simultaneously by the federal cluster.
It can be appreciated that the cluster needing to deploy the container is added to the federation cluster, one cluster is designated as a main cluster of the federation cluster, the rest clusters are member clusters, preferably, only one cluster in one federation cluster is the main cluster, and the main clusters can be switched at will.
Optionally, when receiving an application container deployment instruction sent by the federation cluster management platform and executing the application deployment container to work, the deployment policy is connected to the main cluster, and then issued to each member cluster of the federation cluster by the main cluster.
Optionally, when the application deploys the container through the federal cluster management platform (e.g., a PAAS management platform), it is unnecessary to specify the deployed cluster, and only the number of copies to be deployed under the template is specified, and the deployment policy selects the balanced scheduling policy. After the main cluster is calculated, the calculated result is issued to member clusters of each federal cluster, and finally containers required by application are deployed in the whole federal cluster in a balanced mode, so that the number of the containers is ensured to be the number of the copies deployed by the application.
Step S102: and monitoring whether the state of each member cluster changes, and executing corresponding cluster migration operation according to the change characteristics of the state of each member cluster after monitoring that the state of each member cluster changes.
Alternatively, when a new cluster joins the federation, the federation cluster perceives the joining of the new cluster and recalculates the number of containers each cluster needs to deploy. And starting the application container on the new cluster according to the strategy, and stopping the container on the old cluster, so that the total number of the application deployment containers in the whole federal cluster is ensured to be unchanged. The deployment strategy is completed through an algorithm, and the aim of container migration is achieved under the condition that the restarting quantity of the application container is minimum.
Alternatively, when an old cluster comes down, the cluster is removed from the federal cluster. The federal cluster perceives the cluster removal, and additionally the containers started on the cluster are unchanged, and a corresponding number of containers will be started on the other clusters, keeping the total number of application containers unchanged. The deployment algorithm keeps the containers started on other federal clusters unchanged, and simultaneously, the containers started on the offline clusters are uniformly scheduled on other clusters, so that the total number of the deployed containers applied is unchanged under the condition that the number of the restarted containers is minimum.
As can be seen from the above description, the application container multi-cluster migration method provided by the embodiment of the present application can execute corresponding application container deployment operations by receiving an application container deployment instruction sent by a federal cluster management platform, and according to the total application deployment copy number and the cluster scheduling policy in the application container deployment instruction; and monitoring whether the states of all member clusters change, and executing corresponding cluster migration operation according to the change characteristics of the states of the member clusters after the states of the member clusters are monitored, so that when the clusters are deployed by application, the clusters needing to be deployed are not required to be designated, the cluster information needing to be deployed is not required to be acquired, and meanwhile, when a new cluster is online or an old cluster is offline, the deployment and migration work of an application container in multiple clusters can be accurately, automatically and unintelligly completed.
In order to accurately and automatically perform the application container deployment operation according to the application container deployment instruction, in an embodiment of the application container multi-cluster migration method of the present application, referring to fig. 2, the step S101 may further specifically include the following:
step S201: and determining the deployment number of the application container copies of each member cluster corresponding to the main cluster by the main cluster according to the total number of the application deployment copies in the application container deployment instruction and the cluster scheduling strategy.
Step S202: and the master cluster issues the deployment quantity of the application container copies to the corresponding member clusters, and the member clusters execute corresponding application container deployment operations according to the deployment quantity of the application container copies.
Specifically, when an application container deployment instruction sent by the federation cluster management platform is received and an application deployment container is executed, a deployment policy is connected to a main cluster, and then the main cluster issues the deployment policy to each member cluster of the federation cluster. When the application deploys the container through the federal cluster management platform (for example, a PAAS management platform), the deployed cluster is not required to be specified, only the number of copies to be deployed under the template is required to be specified, and the deployment strategy selects the balanced scheduling strategy. After the main cluster is calculated, the calculated result is issued to member clusters of each federal cluster, and finally containers required by application are deployed in the whole federal cluster in a balanced mode, so that the number of the containers is ensured to be the number of the copies deployed by the application.
In order to automatically and accurately perform the cluster migration operation according to the change of the member cluster state in the federal cluster, in an embodiment of the application container multi-cluster migration method of the present application, the step S102 may further specifically include the following:
monitoring whether a member cluster to be online exists or not through a federal cluster management control component, if so, adding the member cluster to be online into the federal cluster through the federal cluster management control component, deploying application container copies on the member cluster, and stopping deploying the application container copies on the member cluster on which the application container copies are deployed, wherein the number of the application container copies deployed on the member cluster to be online is equal to the number of the application container copies stopped from being deployed on the member cluster on which the application container copies are stopped.
Specifically, when a new cluster joins the federation, the federation cluster senses the joining of the new cluster and recalculates the number of containers that each cluster needs to deploy. And starting the application container on the new cluster according to the strategy, and stopping the container on the old cluster, so that the total number of the application deployment containers in the whole federal cluster is ensured to be unchanged. The deployment strategy is completed through an algorithm, and the aim of container migration is achieved under the condition that the restarting quantity of the application container is minimum.
In order to automatically and accurately perform the cluster migration operation according to the change of the member cluster state in the federal cluster, in an embodiment of the application container multi-cluster migration method of the present application, the step S102 may further specifically include the following:
and monitoring whether a member cluster to be offline exists or not through a federal cluster management control component, if so, removing the federal cluster from the member cluster to be offline through the federal cluster management control component, and increasing the number of application container copies deployed on other member clusters, wherein the number of application container copies deployed on the other member clusters is equal to the number of application container copies deployed on the member cluster to be offline.
Specifically, when an old cluster comes down, the cluster is removed from the federal cluster. The federal cluster perceives the cluster removal, and additionally the containers started on the cluster are unchanged, and a corresponding number of containers will be started on the other clusters, keeping the total number of application containers unchanged. The deployment algorithm keeps the containers started on other federal clusters unchanged, and simultaneously, the containers started on the offline clusters are uniformly scheduled on other clusters, so that the total number of the deployed containers applied is unchanged under the condition that the number of the restarted containers is minimum.
In order to flexibly implement deployment and migration of application containers in multiple clusters, the present application provides an embodiment of an application container multiple cluster migration apparatus for implementing all or part of contents of the application container multiple cluster migration method, referring to fig. 3, the application container multiple cluster migration apparatus specifically includes the following contents:
the application container deployment module 10 is configured to receive an application container deployment instruction sent by the federal cluster management platform, and execute a corresponding application container deployment operation according to the total application deployment copy number and the cluster scheduling policy in the application container deployment instruction.
The cluster migration module 20 is configured to monitor whether the status of each member cluster changes, and execute a corresponding cluster migration operation according to the status change feature of the member cluster after the status of each member cluster is monitored to change.
As can be seen from the above description, the application container multi-cluster migration device provided in the embodiments of the present application may execute a corresponding application container deployment operation by receiving an application container deployment instruction sent by a federal cluster management platform, and according to the total application deployment copy number and the cluster scheduling policy in the application container deployment instruction; and monitoring whether the states of all member clusters change, and executing corresponding cluster migration operation according to the change characteristics of the states of the member clusters after the states of the member clusters are monitored, so that when the clusters are deployed by application, the clusters needing to be deployed are not required to be designated, the cluster information needing to be deployed is not required to be acquired, and meanwhile, when a new cluster is online or an old cluster is offline, the deployment and migration work of an application container in multiple clusters can be accurately, automatically and unintelligly completed.
In order to accurately and automatically perform the application container deployment operation according to the application container deployment instruction, in an embodiment of the application container multi-cluster migration apparatus of the present application, referring to fig. 4, the application container deployment module 10 includes:
the container copy deployment number determining unit 11 is configured to determine, by a master cluster, an application container copy deployment number of each member cluster corresponding to the master cluster according to the total number of application deployment copies in the application container deployment instruction and a cluster scheduling policy.
And the container copy deployment instruction issuing unit 12 is configured to issue, by the master cluster, the application container copy deployment number to each corresponding member cluster, and execute, by the member cluster, a corresponding application container deployment operation according to the application container copy deployment number.
In order to automatically and accurately perform the cluster migration operation according to the change of the status of the member clusters in the federal cluster, in an embodiment of the application container multi-cluster migration apparatus of the present application, referring to fig. 5, the cluster migration module 20 includes:
a newly added cluster migration unit 21, configured to monitor, by using a federal cluster management control component, whether there is a member cluster to be online, and if so, add the member cluster to be online to the federal cluster by using the federal cluster management control component, deploy an application container copy on the member cluster, and stop deploying the application container copy on the member cluster already deployed with the application container copy, where the number of the application container copies deployed on the member cluster to be online is equal to the number of the application container copies stopped to be deployed on the member cluster stopped from deploying the application container copy.
In order to automatically and accurately perform the cluster migration operation according to the change of the status of the member clusters in the federal cluster, in an embodiment of the application container multi-cluster migration apparatus of the present application, referring to fig. 6, the cluster migration module 20 includes:
the removal cluster migration unit 22 is configured to monitor, by using a federal cluster management control component, whether a member cluster to be offline exists, and if so, remove, by using the federal cluster management control component, the member cluster to be offline, and increase the number of application container copies deployed on other member clusters, where the number of application container copies deployed on the other member clusters is equal to the number of application container copies deployed on the member cluster to be offline.
In order to further explain the scheme, the application also provides a specific application example for implementing the application container multi-cluster migration method by applying the application container multi-cluster migration device, which specifically comprises the following contents:
referring to fig. 7, the whole system is constructed. The application deploys a number of containers through a federal cluster management platform (e.g., a PAAS management platform) that distributes the deployment policy to federal cluster management nodes. The federation management node calculates the number of containers to be started on each cluster according to the balanced scheduling strategy, so that the containers are uniformly deployed on each cluster in the federation clusters, and the number of the containers applied on the clusters is ensured to be added up to the number of the containers to be deployed by the application.
Referring to fig. 8, a cluster federation module schematic is shown. Firstly, a management control component of a federation cluster is installed on a master node of a certain cluster, and the certain cluster is selected as a main cluster of the federation cluster. The management control component of the federal cluster controls the addition and deletion of clusters. The primary cluster is responsible for receiving container deployment instructions and distributing to the sub-clusters. When a new cluster is built, after delivery is used, a join command of the management component is called, and the cluster is added into the federal cluster. When an old cluster is offline and an application container is not deployed any more, an unioin command of the management component is called, and the cluster is removed from the federal cluster. The process does not need the participation of an application, and the application does not need to acquire cluster information.
Referring to fig. 9, a schematic diagram is deployed for a federal cluster container. Assuming that there are currently 3 clusters in the federal cluster, 6 containers need to be deployed under one template of an application. The federal cluster will launch 2 containers of applications on each cluster according to the balanced scheduling policy. After the addition of the fourth cluster No.4, a container will start on top of the new cluster No.4 and stop on the old cluster. After the old cluster No.1 goes offline, the federal cluster stops containers previously started on No.1 and automatically dispatches to other clusters to start on top of one another. The total number of containers is unchanged, whether clusters are added or deleted, and the containers are serviced normally. The application does not need to select clusters to be deployed, only needs to specify the total number of clusters to be deployed, and the application does not sense the change of the underlying clusters, so that the transparent use effect of the application is achieved.
From the above, the present application can at least achieve the following technical effects:
by performing federation management on the clusters, the method can automatically deploy the container in the whole federally managed clusters without designating the deployed clusters when the application is deployed. For the platform, cluster reclamation can be performed without waiting for all applications deployed on the cluster to delete their respective containers. The method has the specific advantages that:
1. and in the migration process of the clusters, the application is transparent, and the clusters at the application side are not perceptively migrated.
2. The cluster management and application container deployment relationships are decoupled from each other and not previously dependent.
3. The cluster management platform can timely log off the old cluster, the time consuming time is short, the computing nodes of the old cluster are timely recovered, and resources are saved.
In order to flexibly implement deployment and migration of application containers in multiple clusters from a hardware level, the application provides an embodiment of an electronic device for implementing all or part of contents in the application container multiple cluster migration method, where the electronic device specifically includes the following contents:
a processor (processor), a memory (memory), a communication interface (Communications Interface), and a bus; the processor, the memory and the communication interface complete communication with each other through the bus; the communication interface is used for realizing information transmission between the application container multi-cluster migration device and related equipment such as a core service system, a user terminal, a related database and the like; the logic controller may be a desktop computer, a tablet computer, a mobile terminal, etc., and the embodiment is not limited thereto.
