Real-time synchronization method for state of Docker container

Abstract

The invention discloses a real-time synchronization method for the state of a Docker container. The method comprises the following steps of building a container management platform; building a container, storing container information in an Etcd database, and setting a TTL expiration time of the container; deploying a container monitoring component in a host where the container is located, wherein the container monitoring component periodically reports monitoring data to the container management platform; when the container management platform receives the monitoring data, updating the corresponding TTL expiration time of the container in the Etcd database; monitoring the Etcd database by using the container management platform, when the condition that the container information is deleted is monitored, judging whether the state of the container in the platform database is a stop state by using the container management platform, and if no, updating the state to be the stop state. According to the method, the state of the container under abnormal scenes such as the Docker host is shut down and the Docker progress is stopped can be updated.

Description

technical field [0001] The invention relates to the field of cloud computing container management, in particular to a method for real-time synchronization of Docker container states. Background technique [0002] The management and use of containers is the next stage of cloud computing. Due to its light weight, easy migration, and easy startup, containers are gradually adopted by major cloud computing platforms and provided to developers as services. The container may be shut down or restarted due to the abnormal process running inside it. At this time, the container management platform needs to be able to monitor the state changes of the container in real time and give corresponding alarm information. Docker (open source container engine) provides processing The interface of Docker events, but it cannot handle all abnormal situations, such as the shutdown of the Docker host, the stop of the Docker process, etc. Contents of the invention [0003] To solve the above proble...
