Description

Dynamic cross resource pool operator deployment method, system and storage medium

technical field

The present invention relates to the field of information technology, in particular to a method, system and storage medium for dynamically deploying operators across resource pools.

Background technique

Operator is a way to package, deploy and manage Kubernetes applications. Based on application-specific controllers, it can extend the functions of Kubernetes API to create, configure and manage instances of complex applications on behalf of Kubernetes users. Operator uses custom resource CR to manage applications and their components. Custom resource is an API extension mechanism in Kubernetes. A custom resource definition CRD will specify the CR and list all configurations available to the Operator user. Operators monitor CR types and take application-specific actions to ensure that the current state matches the desired state for that resource. In the PaaS platform application scenario, cloud-native PaaS components are deployed based on operators. With the growth of resource pools and the number of container cloud clusters in resource pools, the number and versions of operators in container cloud clusters are also increasing. How to implement operator deployment? Full lifecycle management such as automatic installation, upgrade, and uninstallation has also become a problem. Therefore, it is urgent to study technologies that can improve the management efficiency of operators.

Before introducing the technical solution of this embodiment, the application scenario of this embodiment is introduced.

Operators are based on application-specific controllers that extend the capabilities of the Kubernetes API to create, configure, and manage instances of complex applications on behalf of users. Operators manage applications and their components using Custom Resources (CR), an API extension mechanism in Kubernetes. A Custom Resource Definition (CRD) specifies a CR and lists all configurations available to Operator users. Operators monitor CR types and take application-specific actions to ensure that the current state matches the desired state for that resource. In the PaaS platform application scenario, cloud-native PaaS components are deployed based on operators. As the number of resource pools and container cloud clusters in resource pools increases, the number and versions of operators in container cloud clusters also increase.

For the dynamic cross-resource pool operator deployment method, please refer to Figure 1, including the following steps:

Step A01) Record the matching relationship between the paas component version and the operator version;

Step A03) record the instance of the paas component of the cloud cluster and the operator version used;

Step A04) Listen for new operator version release messages, and send operator version upgrade tasks to component instances that need to upgrade the operator version;

Step A05) Monitor the logout message of the paas component instance, and if there is an operator version that is not used by any paas component instance, uninstall the operator of the corresponding version from the cloud cluster.

The method for recording the matching relationship between the paas component version and the operator version includes: establishing a matching table between the paas component version and the operator version, and the matching table records the operator version that matches the paas component version.

In this embodiment, version management center 10: the public area version management center 10 provides paas component version and operator version management functions, and maintains the constraint relationship between the paas component version and operator version.

Operator automatic deployment: When the user selects a container cloud cluster in a certain resource pool to activate the paas component, the paas component activation engine first determines whether the operator is deployed in the container cloud cluster. The latest operator version, and then automatically distribute the deployment of the operator, automatically deploy the operator, and record the version relationship between the container cloud cluster instance and the component operator in the instance center, and then provide the basis for the automatic upgrade of the operator version.

Operator automatic upgrade: When a new operator version is released, a notification message will be sent to the operator management dispatching center after the version is released successfully. The operator management dispatching center will obtain all container cloud clusters with the operator installed and generate The operator upgrade task, the operator upgrade task will first obtain the instance version in the container cloud cluster, and judge whether they match the latest operator version. If they match, the operator upgrade chart will be delivered to the resource pool container cluster to automatically pull up the new version of the operator.

Operator automatic unloading: When the deregistration of the paas component instance in a certain container cloud cluster of a certain resource pool is completed, it is judged whether there is an instance of the component in the container cloud cluster, and if it does not exist, the unloading of the operator is triggered.

After receiving the activation command of the paas component of the cloud cluster, it is judged whether the operator matching the version of the paas component has been deployed in the cloud cluster. The version of the paas component, obtain the matching operator version, and deploy the matching operator version.

If the operator version table does not record the operator version that matches the paas component version, it is determined that the cloud cluster has not deployed an operator that matches the paas component version. Conversely, if the operator version table has records that match the paas component version operator version, it is determined that the operator that matches the paas component version has been deployed in the cloud cluster;

Step B04) After deploying the matching operator version, update the operator version table.

The methods for recording the paas component instance of the cloud cluster and the operator version used include:

Create a paas component version table, the paas component version table records the currently used paas component version and the paas component instance set, the paas component instance set records the paas component instance and the operator version used by the paas component instance.

Query the paas component version table to obtain the paas component instance set corresponding to the old operator version, that is, the paas component instance set that needs to be upgraded to the operator version, and the paas component instances in the paas component instance set are the paas component instances that need to be upgraded to the operator version.

The methods for judging whether the operator version is used by the paas component instance include:

Query the paas component version table to obtain the paas component instance set corresponding to the operator version. If the paas component instance set is empty, it is determined that the operator version is not used by any paas component instance. Conversely, if the paas component instance set is not empty, it is determined that the operator The version is used by the paas component instance.
