Background
Distributed applications are different from traditional single applications deployed by a single execution entity, multiple execution entities are respectively deployed on common servers connected through a network, and the distributed applications are a mode for realizing high-performance computing by using a large number of computing resources through distributed organizations. The distributed application can balance cost and benefit, but at the same time, the complexity of the distributed application brings great challenges to work such as publishing, monitoring, upgrading and fault handling, and a complete set of life cycle management mechanisms and technologies are needed to process.
In the prior art, a distributed system is usually built by adopting a virtual machine technology, and a container virtualization technology is a solution capable of replacing a traditional virtualization technology, so that the efficiency and reliability of the container virtualization technology are rapidly developed. The container virtualization technology can isolate different processes running on a host computer, so that the processes, the process and a host operating system are isolated from each other and do not influence each other. Currently, the mainstream container technology focuses on the isolation of a single container and resources, and relies on a container cluster management technology for supporting cluster management.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a lifecycle management method for a distributed application according to an embodiment of the present invention, where this embodiment is applicable to a situation of performing full lifecycle management on a product and an application published on a distributed cluster management platform, and the method may be applied to a lifecycle manager, which is executed by the lifecycle manager, and the lifecycle manager may be published in advance on the distributed cluster management platform and implemented in a software and/or hardware manner. The distributed cluster management platform is a platform for managing a large number of containers on distributed hardware resources, including but not limited to kubernets and media marathon, and can be integrated in a computer device or distributed device. As shown in fig. 1, the method specifically includes:
s110, responding to an issuing instruction of an issuing object, calculating to obtain an issuing list of the issuing object, wherein the issuing object comprises a product or an application, the issuing list comprises a plurality of application instances and issuing sequences among the application instances, and the life cycle manager is issued on a distributed cluster management platform in advance.
The application defines a set of complete distributed applications, which is different from the fine-grained concepts defined in the container cluster management technology in the prior art, such as a service or a container group, and the application is a combination and high-level abstraction of the fine-grained concepts, and is a distribution set formed by dynamically combining the fine-grained concepts in the prior container cluster management technology by using configuration data, and provides distribution, scheduling, monitoring and analysis capabilities to the outside by using the set as a unit. The product is a combination of applications, is positioned at a complete solution package level, provides a view of a high-level solution to the outside, and can manage a plurality of sets of associated distributed applications at a higher level.
The notion that an application corresponds at runtime is an instance, which is a collection of truly running program entities. Taking a kubernets platform as an example, the most basic issuing entity on the kubernets platform is Pod, and concepts such as delivery, stateful, Service and the like are constructed on the Pod, so that the concepts need to be integrated and issued together when a complete and available distributed Service is issued on the kubernets. The embodiment of the invention defines and realizes the concept of the application example as a basic scheduling unit by adopting a customized resource definition mode provided by Kubernetes. In the embodiment of the invention, the application instance can be used for completely issuing a set of distributed application services by one operation on the basis of providing simple parameter configuration, for example, the components of Namenode, DataNode, Secon dNamenodenode and the like of the HDFS of the distributed file system are issued by one key, so that the HDFS distributed application instance which is used in an open box is obtained.
The product application instances are usually multiple and have certain relevance, and before being published, the publication sequence of the product application instances needs to be determined in a publication list so as to implement parallel or sequential publication according to the publication sequence.
In addition, it should be noted that the issue instruction may be issued by a developer when a product or an application needs to be issued, or may be issued by an already issued application. For example, when an already published application needs to depend on a certain function or needs to dynamically start one or more applications to complete a certain job during running, a target application capable of realizing the function may be created in the application, that is, the target application or job is taken as a publishing object, and a publishing instruction for the target application or job is issued. The applications published by the applications are called child applications of the source application, the source application is called a parent application of the child application, the publishing relationship of the applications is organized by using a tree relationship, and the life cycle of each child application can be managed by the parent application of the child application.
And S120, sending the release list to an application instance manager, wherein the application instance manager is pre-released on the distributed cluster management platform and is used for releasing the application instance according to the release list and monitoring the running state data of the released application instance.
The application instance manager and the life cycle manager are the same and are pre-issued on the distributed cluster management platform, and during implementation, the application instance manager can be customized according to the distributed cluster management platform, so that function expansion and management of the distributed cluster management platform are realized. The lifecycle manager may communicate with the application instance manager to obtain the operating state data it monitors.
S130, collecting the running state data monitored by the application instance manager, and storing the running state data and the release data related to the release object.
And S140, analyzing the performance of the release object according to the stored data.
Specifically, the lifecycle manager may communicate with the application instance manager to collect the operation state data monitored by the application instance manager, and store the operation state data and the release data related to the release object, for example, in a database. The running state data includes, for example, a product publishing state (e.g., publishing, running, restarting, suspending, recovering, deleting, etc.), a resource consumption state (e.g., real-time CPU, memory, storage, network bandwidth, etc.) in running of each instance in the product, a task state (e.g., running time, restarting times, task time consumption, error times, etc.) included in each instance in the product, publishing data related to a publishing object includes, for example, version information of the product and application instance, and various configuration parameters (e.g., CPU, memory, disk, bandwidth, etc.) of the product and application instance.
The stored data can be used for analyzing the performance of the published objects, and the health condition of the published objects can be evaluated by analyzing the performance of the published objects, so that reference or early warning is provided for technicians.
The embodiment of the invention publishes the life cycle manager and the application instance manager on the distributed cluster management platform in advance, responds to the publishing instruction of the publishing object through the life cycle manager, calculates the publishing plan of the publishing object, publishes through the application instance manager, monitors the running state data of the published application instance, collects the running state data through the life cycle manager, stores the running state data together with the publishing data related to the publishing object, and analyzes the performance of the publishing object according to the stored data, thereby realizing not only the publishing, configuration and version management of the application, but also the publishing, monitoring and management of the published application and having complete life cycle management capability.
Example two
Fig. 2 is a flowchart of a lifecycle management method for distributed applications according to a second embodiment of the present invention, and the second embodiment is further optimized based on the foregoing embodiments. As shown in fig. 2, the method specifically includes:
s210, receiving an issue instruction for an issue object, wherein the issue instruction carries configuration parameters of the issue object. The configuration parameters correspond to user requirements, and include, for example, the number of applications issued in the product, various configuration parameters (including, for example, CPU, memory, disk, and bandwidth) of the product and the applications, an externally exposed service interface in the product, and specific configuration parameters that the user needs to apply to each application in the product.
For example, if the user instructs to publish on another service, the other service may make a function call through the HTTP protocol in connection with the RESTFul interface provided by the lifecycle manager, and the lifecycle manager thus receives a publishing instruction of the publishing object issued by the user on the other service. The lifecycle manager may also provide a management means in the form of a client through which the user may directly use the various functions of the application lifecycle manager.
S220, analyzing the issuing instruction to obtain the configuration parameters of the issuing object.
And S230, calculating a target resource quota required by the instantiation deployment according to the configuration parameters and the configuration template.
S240, acquiring the used resource quota of the current distributed cluster through the application instance manager, and if the used resource quota meets the requirement of the target resource quota, calculating to obtain the issuing list of the issuing object according to the configuration parameters and a predefined configuration template.
The configuration template may be predefined, the configuration template may define a logical relationship between different applications, and a target resource quota required by the instantiated deployment, for example, how many containers and other cluster resources are required, is determined by calculation according to the configuration parameters and the configuration template. If the used resource quota cannot meet the requirement of the target resource quota, the successful release is indicated, and failure information and failure reasons can be fed back to the user; if the requirement can be met, the process is continued, and the release list is calculated, so that the correctness of the release is ensured, the success rate is improved, and the waste of resources is avoided.
Further, if the used resource quota meets the requirement of the target resource quota, a distribution list of the distribution object is obtained by calculation according to the configuration parameters and the configuration template, which specifically includes:
if the issuing instruction is an updating issuing instruction, acquiring configuration parameters of the issued object corresponding to the issued object, and generating an updating issuing list through comparison operation of the configuration parameters;
if the issuing instruction is an issuing instruction for the first time and the issuing object is a target product, calculating an issuing list of the target product according to configuration parameters and a configuration template of the target product;
if the issuing instruction is the first issuing instruction and the issuing object is the target application, whether the target application is deployed in the issued product is judged, if yes, issuing data related to the issued product is obtained, the issuing data related to the issued product is injected into the issuing list of the target application after the issuing list of the target application is calculated, and if not, the issuing list of the target application is calculated according to the configuration parameters and the configuration template of the target application.
The issue instruction may include various instructions, such as an update issue instruction and a first issue instruction. Wherein, for the update issue instruction, the updated part of the product application is identified through the comparison operation, and the issue list is generated based on the updated part, and meanwhile, the updated part is saved. Aiming at a first-time issuing instruction, different processing modes are adopted for different issuing objects, an issuing list can be directly calculated for the first-time issuing of a product, and for the first-time issuing of an application, whether the application is deployed in an issued product needs to be judged firstly, then different strategies are adopted, and meanwhile issuing related data are stored, so that issuing processes with different granularities are realized.
Specifically, coarse-grained application publishing and management is mainly aimed at a product level, a whole set of product instances can be published one key by using the process to form a publishing cluster, fine-grained application publishing and management is mainly aimed at an application level, and application can be finely and flexibly controlled by using the process.
In addition, for the case of the release failure, retry can be performed according to the configuration, if retry failure occurs, all previous releases need to be cancelled, and the reply state fails and exits.
And S250, sending the release list to the application instance manager.
And S260, collecting the running state data monitored by the application instance manager, and storing the running state data and the release data related to the release object.
And S270, analyzing the performance of the release object according to the stored data.
According to the embodiment of the invention, the lifecycle manager is used for realizing issuing processes with different granularities aiming at different issuing instructions and issuing objects, and specifically, for complex applications formed by multiple sets of distributed application services, the coarse granularity concept is used for abstracting and managing the complex applications (such as multiple sets of distributed applications with incidence relations), so that the management difficulty of the complex applications is reduced; for the bottom-layer application needing fine control, the application is flexibly controlled by using fine-grained concept abstraction and management capability. Therefore, the method is oriented to the end user, and can be released by one key and used after being opened; the distributed service life cycle management scheme is comprehensive and flexible and faces to system managers or developers.

And responding to the query instruction of the issued object, and acquiring and feeding back a query result through the application instance manager.
For the state query and management instructions of the product or the application, the life cycle manager can directly acquire or communicate with the application instance manager to acquire information such as the running state, configuration, task running and resource use conditions of the cluster or the application instance, and respond to the query instructions after calculation.
S360, monitoring the state change of the published object according to the stored running state data and the preset triggering rule, and notifying or alarming when the state change of the published object meets the triggering rule.
Specifically, after the product or the application is successfully released, the process enters a state management and application analysis process, including but not limited to the operations of S340-S360. For instance clusters or application instances running after the product or application is released, the state management and application analysis process starts from the successful release of the product or application for the first time until the product or application exits successfully or fails.
In the process of state management and application analysis, firstly, an application instance manager issues a list according to a cluster/instance, and inquires the state according to the list, when a product or application issuing process is successful, the application instance manager needs to be passed, the state management and application analysis process monitors whether all entities really running on a distributed container cluster corresponding to the cluster/application are completely and normally running, and reporting is needed through a life cycle manager or rescheduling is needed for a failure condition. The life cycle manager can collect and record all monitored events of the cluster/instance and update the result of application analysis in real time according to the events; and if the event needing to be reported is a cluster and application end event, triggering to generate a final application analysis report and reporting the final application analysis report together with the event, otherwise, reporting the event independently.
