Problems solved by technology

[0004] However, in the process of deleting the container, the processing processes of each component are executed concurrently, and the execution order of each process cannot be strictly controlled. The business may be affected due to the unreasonable execution order, which may lead to the loss of container data or business interruption

Embodiment Construction

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0065] First, combine figure 1 , briefly explaining the structural composition of the container cluster management system in the traditional technology and the implementation process of deleting containers.

[0066] Such as figure 1 As shown, the container cluster management system includes a management node and several service nodes connected to the management node. Among them, the management node includes API (interface) server, Etcd database and endpoint controller. The API ser...

Abstract

The invention relates to a container management and control method and a processing node. After a management node deletes container information of a first container on the basis of the obtained deletion request for the first container and stops receiving and / or forwarding of a connection request for the first container, a service node removes routing information of the first container, and feeds back first deletion state information of the first container routing information to the management node, the management node sets the state of the first container to be a second state when determiningthat the service node satisfies a deletion condition for the routing information of the first container based on the obtained at least part of the first deletion state information, and the service node triggers to execute a deletion operation for the first container based on the second state of the first container. Visibly, the execution sequence of each component processing flow in the containerdeletion process is strictly controlled, the correct processing logic of container deletion can be ensured, and data loss or service interruption in the container deletion process is avoided.

Description

technical field [0001] The present application belongs to the field of container cluster management, and in particular relates to a container control method and a processing node. Background technique [0002] The container cluster management system is an open source platform, including a management node and at least one service node, which can realize automatic deployment, automatic expansion and contraction, maintenance and other functions of container clusters based on each node. K8s (Kubernetes) is a relatively common container cluster management system, created by Google, and is an open source version of Borg, Google's large-scale container management technology. [0003] At present, when a container cluster management system such as K8s deletes a container, the API server in the management node will first set the container state to Terminating (terminating) state, and each component in the cluster node monitors this state and executes its own processing synchronously ...
