Problems solved by technology

When the cluster is deployed in a multi-physical machine X multi-virtual machine solution, if a single physical machine fails, all virtual machines / nodes of the machine will be unavailable, which may lead to serious availability problems in the entire K8s cluster
Therefore, it is necessary to manually assign the master node (master) to a virtual machine located on a different physical machine to deal with the availability problem caused by the failure of a single physical machine and the failure of all nodes on the same machine

Embodiment Construction

[0037] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0038] This container high-availability deployment method reasonably configures the scheduling strategy based on the anti-affinity feature of K8s, and forcibly schedules multiple copies of the same application to virtual machine nodes located on different physical machines, thereby ensuring the high availability of the cluster.

Abstract

The invention particularly relates to a high-availability deployment method for containers. According to the container high-availability deployment method, a scheduling strategy is reasonably configured based on the anti-affinity characteristic of K8s, and multiple copies of the same application are forcibly scheduled to virtual machine nodes located on different physical machines, so that the high availability of a cluster is ensured. According to the container high-availability deployment method, automatic scheduling of the cluster key Pod on different physical machine nodes can be realized,and the problem that the scheduling of the cluster key Pod is abnormal due to the fact that a plurality of virtual machine nodes are unavailable caused by a single physical machine fault is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of cluster deployment, in particular to a high-availability deployment method for containers. Background technique [0002] Kubernetes (K8s) is a brand-new leading distributed architecture solution based on container technology. Based on Docker technology, it provides containerized applications with a series of complete functions such as deployment and operation, resource scheduling, service discovery, and dynamic scaling, which improves the Convenience and high availability of large-scale container cluster management. [0003] The main function of a container platform is to allocate computing, storage, and network resources required for runtime to containers. The container scheduling system is responsible for selecting the most suitable hosts to start containers on and associating them. It must be able to automatically handle container failures and automatically start more containers on more hosts to hand...
