How to understand the operation of Docker container

Today, I will talk to you about how to understand the operation of the Docker container. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

Whether you have mastered the knowledge of Docker container operation, there are two points that need to be added:

You can create the container first and start it later.

The container created by ① docker create is in the Created state.

② docker start starts the container in the background. The docker run command is actually a combination of docker create and docker start.

-- restart takes effect only when the container's startup process exits.

Exit includes normal exit or abnormal exit. Here are two examples: if the startup process exits normally or OOM occurs, docker will determine whether the container needs to be restarted according to the policy of-- restart. However, if the container exits because of a docker stop or docker kill execution, it does not restart automatically.

After reading the above, do you have any further understanding of how to understand the operation of Docker containers? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
