Detailed process of modifying hostname after Docker creates a container

There is a medicine for regret in the world, as long as you are willing to think about it! No more recreating containers!

I have a container called m2 and now I want to change its hostname

1. Check the location of the container configuration file on the host machine. Here we see /var/lib/docker/containers/67e012c02434168aff3762ab4edf7550f0bfe1db57b396ce78660f140dd3056e

2. Shut down the container and shut down the docker service prerequisites, which is very important! ! ! Prerequisites are very important! ! ! Prerequisites are very important! ! !

3. Enter the host folder where the configuration file of the container is located, search for the original hostname, and you can see that we need to modify three places, the files are config.v2.json, hostname, hosts

4. Make a backup before modifying

5. Modify these 3 places

6. Start the docker service, start the container, and check the hostname

hostname modified successfully! Are you surprised? ! !
