The method comprises the following steps:
in particular, to create a cluster on a virtual machine, a first virtual machine may be created, which may serve as an installation node of the cluster.
Specifically, after the first virtual machine is created, a first key parameter may be obtained, where the first key parameter may be used as an initialization environment variable for starting a cluster creation application instance, and then the cluster creation application instance may be started based on the first key parameter, a container mirror image corresponding to the cluster creation application instance is solidified with a dependent component of an allowed server and a task script of cluster management, and the cluster creation application instance may execute a cluster creation operation.
Optionally, the cluster management method provided by the present invention may be applied to a containerization platform, and the containerization platform may use Openstack as an infrastructure layer. The main role of Openstack is to decouple the physical and logical topology of the IT system. By running a plurality of operating systems (namely virtual machines) on one machine at the same time, the problem of improving the resource utilization rate of a physical machine under the condition of ensuring the independence and isolation of service instances can be solved.
Optionally, the containerization platform may construct a container arrangement engine based on K8S on the infrastructure layer, so as to achieve finer-grained resource utilization, and achieve dynamic lateral expansion of physical resources according to a service load by means of the container arrangement capability of K8S.

On this basis, the containerization platform may further incorporate K8S as an Openstack base. By combining the component containerization technology and the container arrangement technology, the containerization platform can realize multiple copies, high availability and dynamic expansion and contraction of Openstack service granularity, and can simplify the deployment of Openstack. The core components of Openstack all run in Pod on the K8S base. Openstack inter-component communication can be converted into inter-Pod communication.

The CCM front end, the CCM back end, the Job of cluster management operation and the containers of the Openstack control plane can be communicated with each other through a K8S two-layer network.
Optionally, the CCM back end may be a micro service developed based on Client go, and may implement communication with a K8S message bus and an Openstack core component, and the CCM front end may be a user operation interface. The interface of the CCM rear end can be directly called by the front end interface, and then the CCM rear end is responsible for operating the Openstack and K8S interfaces, so that the virtual machine can be created, and Job can be started.
Alternatively, Job's container mirror may have all of the underlying dependent components of the ansable server fixed, such as python, open-ssh, etc. While task (task) scripts for cluster management may also be solidified into the Job container image. Job's entrypoint (entrypoint specifies the mirror's default entry command) is set to receive the participating Shell script. The parameters of the Shell script are all obtained from the environment variable env of the container. Different management processes can be performed depending on the acquired parameters: such as creating clusters, deleting clusters, scaling clusters, upgrading nodes in clusters, etc. Job may interact with the virtual machine via the SSH protocol.
Optionally, the virtual machine needs to be started according to a preset virtual machine image, and all software packages that the K8S cluster depends on when deployed may be solidified in the preset virtual machine image.

In a large-scale use scenario, the CCM can perform multi-copy deployment and elastic expansion and contraction. Job is a lightweight container, and is flexible to deploy and quick to start and stop. The method has important significance for enhancing Platform as a Service (PaaS) Platform user experience and ensuring the stability of the PaaS Platform.

Optionally, the first key parameter includes: the method comprises the steps that an IP address of a first virtual machine, a root password of the first virtual machine, a cluster version and a cluster-dependent container runtime type are set; the container arrangement engine is Kubernetes; the starting the cluster creation application instance based on the first key parameter comprises:

and starting the target application instance based on the second key parameter, wherein the target application instance runs on the container arrangement engine in a work class container form.
Specifically, after a cluster is created, in order to implement cluster management functions such as cluster expansion, cluster contraction, cluster deletion, cluster upgrading or cluster rollback, a cluster management task may be determined, and then based on the cluster management task, a second key parameter for cluster management may be obtained, and then a target application instance may be started based on the second key parameter, a container mirror image corresponding to the target application instance is solidified with an ansable server dependent component and a cluster management task script, and then the target application instance may execute operations such as cluster expansion, cluster contraction, cluster deletion, cluster upgrading or cluster rollback, and the like, the target application instance operates on the container arrangement engine in a work-class container form, and after the cluster management operation is executed, a container corresponding to the target application instance may exit, and automation of various cluster management may be implemented.
It will be appreciated that the CCM has the capability to communicate with both Openstack core components and api-servers of the K8S base.
In one aspect, the CCM may complete management of the virtual machine by invoking an Openstack interface, such as creation, addition, deletion, and the like of a virtual machine node.
On the other hand, the CCM can communicate with the api-server of the K8S base to create other services Pod to accomplish specific functions. The management work of the K8S cluster on top of the virtual machine can be assumed by the service Pod. The service Pod is configured as an allowed server by solidifying the allowed task (task) in the mirror. The CCM may pass virtual machine node information (IP address, username password, etc.) to the ansable server container in the form of environment variable injection and pull the Pod. And executing the cluster management task according to the joined constraint after the Pod is started. The Pod has a significant lifetime, i.e. the lifetime is the time to execute a management command, so the Pod runs in Job style in the K8S base.

Optionally, in a case that the cluster management task is the cluster extension task, the second key parameter includes: the method comprises the steps of setting a cluster version and a cluster-dependent container runtime type, wherein the cluster version comprises an IP address of a first virtual machine, a root password of the first virtual machine, an IP address of a second virtual machine, a root password of the second virtual machine, and the cluster runtime type.

in step 607, after the cluster expansion is completed, the CCM front end may display the cluster Ready.
It will be appreciated that cluster minification is similar to cluster expansion, except that the flow needs to be reversed and the virtual machines deleted after Job complete.
It is understood that the cluster delete may be a pull of the cluster delete Job, which deletes the virtual machine after Job comelinee. (if the user has cleared the service, the virtual machine can also be deleted directly)
Optionally, after the starting of the cluster creation application instance based on the first key parameter, the method further includes:
displaying first information for indicating that a cluster is ready in case that the execution of the cluster creation application instance is determined to be completed;
