docker-rerun

docker-rerun is a small utility script that makes it easy to re-run docker containers using the same arguments you used previously.

Want to update to a newer image, or add a missing port publication? docker-rerun’s got you covered.

How to use it

In the most basic usage, you pass in a container name and it will be stopped, deleted and recreated:

$ ./docker-rerun apache

To check what exactly is going to be performed beforehand, use the --dry-run option:

$ ./docker-rerun --dry-run apache
docker stop apache
docker rm apache
docker run --name=apache -p=80:80/tcp --restart=always apache:latest

What’s supported

At present docker-rerun supports a small number of commonly used arguments:

* Commands (trailing arguments)
* Environment variables (-e/--env)
* Labels (-l/--label)
* Names (--name)
* Networks (--net)
* Port publications (-p)
* Restart policies (--restart)
* User switching (-u/--user)
* Volumes (-v/--volume, and --volumes-from)

What’s not done yet

Many other command line arguments:

* Linking and aliases
* Permissions and policies
* Advanced networking options

Additional options to allow mutating the container config when rerunning. For example:

$ ./docker-rerun --image nginx:1.11.1 nginx

Should replace the previously used image with the one specified.
