Can I pass environment variables to a Docker container using Cockpit?

Question

I don't see such an option in the UI:

.

Answer 1

You can probably pass it in the command field

Try -e MYENV=24 and see if that shows up in the container

Answer 2

According to a comment by a Cockpit developer, the UI doesn't currenly expose the ability to specify environment variables when starting a container.

The recommended approach is to simply run docker run from the command line and pass the environment variables in the traditional way, thus bypassing Cockpit's Run Image dialog:

docker run -e "MYENV=24" myimage

Once created, the resulting container can still be monitored and managed from Cockpit.
