Description

Technical Field

[0001] The present invention relates to the technical field of deployment of distributed clusters, and in particular to a method and system for deploying an OpenShift cluster based on a cloud platform. Background Art

[0002] OpenShift is a container-based application platform that provides a complete environment for developing, deploying and managing enterprise-level applications. OpenShift uses Docker containers to package and run applications, ensuring application portability and consistency. OpenShift is based on Kubernetes (K8s), an open source container orchestration platform that provides features such as automatic expansion, rolling updates, and self-healing. In OpenShift, a cluster consists of a group of worker nodes, which can be physical servers or virtual machines. The nodes in the cluster run multiple containerized applications. OpenShift supports a multi-tenant architecture, allowing multiple projects to run in the same cluster, each with its own resource quotas and security policies. OpenShift provides an automated deployment process that supports continuous integration and continuous deployment (CI / CD) from source code to running applications. OpenShift clusters are ideal for enterprise-level application development and deployment, especially for scenarios that require high availability, scalability, and security. With OpenShift, enterprises can quickly build, deploy, and manage complex applications while reducing operational complexity and costs.

[0003] In the prior art, when deploying OpenShift, you first need a bastion server, deploy a load balancer, DNS, http server, and private image repository in the bastion server, configure the deployment list of OpenShift, and then use the OpenShift-install command to generate the ignition file required by coreos. When installing the boot node and master or worker node of OpenShift, you need to enter the livecd mode and use coreos-installer to specify the ignition file to install the operating system. The whole process is cumbersome and complicated, and if any key link in the middle has an error, it needs to be redeployed. Among them, the bastion refers to a collection of resources required to install the OpenShift cluster, including a load balancer, DNS resolution, http server, and private image repository, as well as the ignition files required by coreos; the bootstrap refers to the boot node when installing OpenShift, which is mainly used to create a temporary control plane. When the master node is deployed, the temporary control plane is transferred to the master node, and the control plane is transferred to the master node; the master node is the management node of the OpenShift cluster, responsible for managing the entire OpenShift cluster; the worker node is the working node of the OpenShift cluster, and all business pods run on the worker node. Summary of the invention
