Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.
The application provides a method for application release in a CaaS environment, a device for application release in the CaaS environment and electronic equipment. The following detailed description and the description of the steps of the method are individually made with reference to the drawings of the embodiments provided in the present application.
The embodiment of the method for issuing the application in the CaaS environment provided by the application comprises the following steps:
referring to fig. 1, which is a process flow diagram illustrating an embodiment of a method for application publishing in a CaaS environment according to the present application, referring to fig. 2, which is a schematic diagram illustrating a first container cluster according to the present application; referring to fig. 3, there is shown a schematic diagram of a second container cluster provided herein; referring to fig. 4, a schematic diagram of a third container cluster provided herein is shown. In addition, please refer to fig. 1 to determine the relationship between the steps of the embodiment of the method for issuing the application in the CaaS environment.
Step S101, a new application instance of the application to be issued is created in a container running on a node in the container cluster and started.
The embodiment of the application takes the currently common blue-green release as an example, which illustrates that the application release is realized in a CaaS environment, the smallest dimension of the blue-green release deployed in the CaaS environment is a container, and the smallest dimension of the release is an application, and simply speaking, the blue-green release is an application-level updating operation, and you can switch between two versions of an application, for example, an old version of the application is unchanged, and a new version is deployed. In addition, the blue-green release realized in the CaaS environment has the advantages that the minimum unit distributed in the CaaS environment is a mirror image, the mirror image can be started in different software environments, the dependence on the bottom layer software environment is not needed, and therefore various software environments can be compatible.
The container cluster in the embodiment of the application refers to a cluster composed of at least one virtual machine in a CaaS environment, the virtual machine in the container cluster is used as a node for running a container, and the application to be issued runs in the container running on the virtual machine. For example, as shown in fig. 2, the container cluster shown therein includes VM1 (virtual machine 1, i.e., node 1) and VM2 (virtual machine 2, i.e., node 2), wherein instance 1 and instance 2 of application a are respectively run in 2 containers (Docker containers) on VM1, and instance 3 of application a is run in a container (Docker container) on VM 2.
In specific implementation, load balancing of nodes in the container cluster is implemented based on a preset cluster load balancing module, where the load balancing module is configured to load a load request sent by a user to a virtual machine in the container cluster, and each virtual machine in the container cluster is provided with and started up a load balancing module, and the cluster load balancing module receives the load request sent by the user and performs routing according to a preset routing rule, and distributes the load request to the load balancing module on a corresponding node in the container cluster. In addition, in any node in the container cluster, the load balancing of the container level on the node is realized through the load balancing module arranged on the node, the load balancing module receives the load request sent by the cluster load balancing module, carries out container addressing according to the routing information monitored by the preset service discovery module, and routes the received load request to the corresponding container for processing. For example, as shown in fig. 2, load request 1 and load request 2 received by SLB (cluster load balancing module) are sent to HAProxy (load balancing module) on VM1 and HAProxy (load balancing module) on VM2 in the container cluster, respectively; the HAProxy arranged on the VM1 monitors the routing information at the Discovery Server (service Discovery module), and addresses according to the monitored routing information, and routes the load request 1 to the corresponding container on the VM1 for processing; similarly, the HAProxy provided on VM2 listens to the routing information at the Discovery Server and performs addressing according to the heard routing information, and routes load request 2 to the corresponding container on VM2 for processing.
Further, all load balancing modules arranged on the nodes in the container cluster monitor the routing information stored in the same service discovery module; correspondingly, the load balancing module arranged on any node in the container cluster can load the application instances running in the container on all nodes in the container cluster. For example, as shown in fig. 2, the HAProxy on VM1 and the HAProxy on VM2 listen to the routing information of the Discovery Server, and the heard routing information includes the routing information of VM1 and the container on VM2, so the HAProxy on VM1 can be loaded on instance 1 and instance 2 of application a running in the container on VM1 and can also be loaded on instance 3 of application a running in the container on VM2, and similarly, the HAProxy on VM2 can also be loaded on instance 1, instance 2 and instance 3 of application a running in the container on VM1 and VM 2.
In the step, a new application instance of the application to be issued is created in a container running on a node in the container cluster, and the newly created new application instance of the application to be issued is started. In specific implementation, when a new application instance of the application to be published is created in a container running on a node in the container cluster, the new application instance of the application to be published may also be created on the node where the original application instance of the application to be published is located, that is: and creating the new application instance in a container (second container) on a node where a first container running the original application instance is located, wherein the second container is located on the node where the first container is located in the container cluster. For example, as shown in fig. 3, instance 1 (original application instance 1) and instance 2 (original application instance 2) of application a are running in a container (first container) on VM1, a new instance 1 (new application instance 1) of application a is created in a container (second container) on VM 1; instance 3 of application a (original application instance 3) is running in a container (first container) on VM2, new instance 2 of application a (new application instance 2) and new instance 3 of application a (new application instance 3) are created in a container (second container) on VM 2; and starts new instance 1 and new instance 2 created within the container on VM1 and new instance 3 created within the container on VM 2.
In a scenario of release or update of a version of an application to be released, the original application instance corresponds to an old version of the application to be released, and the new application instance corresponds to a new version of the application to be released. For example, as shown in fig. 3, instance 1, instance 2, and instance 3 of application a correspond to the current 2.0 version of application a, and new instance 1, new instance 2, and new instance 3 of application a correspond to the 2.1 version or the 3.0 version of application a, i.e., to be updated.
In addition, in the implementation, after the step is executed, that is, after a new application instance of the application to be published is created and started in a container running on a node in the container cluster, the following step may also be executed:
for each node of the cluster of containers running the second container, performing the following: and registering the state information of the second container running on the current node to a preset service discovery module through a preset agent module on the current node. It should be noted that the state information at least includes the routing weight; in addition, the state information may further include other routing information except the routing weight, version information of the application to be published, and service discovery addresses of the first container and the second container. For example, as shown in fig. 3, an Agent (proxy module) on VM1 registers status information of a container running the newly created new instance 1 of application a on VM1 with the Discovery Server; the Agent on VM2 registers with the Discovery Server the state information of the container on VM2 running the newly created application a new instance 2 and new instance 3.
And step S102, switching the routing weight of the first container and the second container through a preset load balancing module on the node.
In the above step S101, a new application instance of the application to be published is created in a container running on a node in the container cluster, and the newly created new application instance is started, in this step, on the basis of the above step S101, a routing weight of a first container and a routing weight of a second container are switched by a preset load balancing module on the node, where an original application instance of the application to be published runs in the first container, and the new application instance runs in the second container.
In specific implementation, for each node where the first container and the second container are located, the following steps are performed: and the load balancing module on the current node switches the routing weights of the first container and the second container according to the state information of the first container and the second container monitored by the service discovery module. In a blue-green release scene, the routing weight value is not 0, namely 100, so that the routing weight of the first container before switching is 100, and the routing weight of the second container before switching is 0; and, the routing weight of the first container after switching is 0, and the routing weight of the second container after switching is 100.
For example, as shown in fig. 3, which shows the routing weights before handover: on VM1, the container (first container) running instance 1 and instance 2 of application a has a routing weight of 100 and the container (second container) running new instance 1 of application a has a routing weight of 0; on VM2, the container (first container) running application a's instance 3 has a routing weight of 100 and the containers (second container) running application a's new instance 2 and new instance 3 have a routing weight of 0.
As shown in fig. 4, which shows the routing weights after handover: on VM1, the routing weights of the containers (first container) running instance 1 and instance 2 of application a are switched from 100 to 0, respectively, and the routing weight of the container (second container) running new instance 1 of application a is switched from 0 to 100; on VM2, the routing weight of the container (first container) running instance 3 of application a switches from 100 to 0, and the routing weights of the containers (second containers) running new instance 2 and new instance 3 of application a switch from 0 to 100, respectively.
Step S103, the release confirmation operation is executed for the application to be released.
In step S102, the routing weights of the first container running the original application instance of the application to be released and the second container running the new application instance are switched by the load balancing module preset on the node, and on this basis, in this step, a release confirmation operation is executed for the application to be released, so that the old version of the application to be released is completely offline and the new version of the application to be released is completely online. In specific implementation, the old version of the application to be released can be destroyed by deleting the original application instance of the application to be released, so that the new version of the application to be released is completely online.
In practical application, multiple specific implementation manners may be adopted to implement the release confirmation operation, for example, release verification is performed on the application to be released, and if the release verification is passed, a new version of the application to be released is released. The various forms of implementing the release confirmation operations are merely implementation changes, and do not depart from the core of this application, and therefore, are all within the scope of this application.
To sum up, the method for issuing the application in the CaaS environment, provided by the application, creates a new application instance of the application to be issued based on a container running on a node in a container cluster, starts the new application instance to be newly created after the creation is completed, and realizes the routing switching between the first container and the second container by aiming at the first container and the second container of the new application instance running on the node in the container cluster, and the application to be issued is issued and confirmed after the routing switching, so that the application to be issued is issued. The method for issuing the application in the CaaS environment realizes the route switching among different containers in the CaaS environment in a weight mode, realizes the issuing of the application on the basis, and is simple and convenient to realize; and the deployment and the starting of the application and the route switching among the containers can be combined, so that more automatic application release is realized, and the method is more comprehensive and more applicable.
