How to reload environment variables file in a running Docker container

Question

I have a running container with an environment variables file mounted as such:

docker run -d --env-file ./env.list my/image and everything is working well, now I have updated my ./env.list file and would like the updated files to be reflected. Tried restarting the container but that didn't work.

Solution

It's currently not possible. Check this and this.

See if using docker commit to save the state and create a new instance will fit your situation.

Thanks for the references, pretty helpful. Unfortunately the only way is to re-run the container for now.
