Ability to create environment variables/file for use in Docker containers

Recommended Posts

Similar to how you can create a .env file when using docker-compose, in other projects I would put a number of variables in here that I could use across a number of containers and reference them with ${VARIABLE_NAME}


I use Traefik as my reverse proxy, setting up all those labels was a bit time consuming, setting up new containers would be simplified if I could have label values stored as variables that I could reference. If I ever change my host, I have a LOT of containers to update vs updating a single variable

Also when testing mysql containers with predefined username and password. I'm sure there are plenty more use cases


A small section on the Docker tab to allow managing of variables, and then of course the ability to then use them when creating/editing a container


In addition, Docker also allows using a file with the --env-file option, I know I could do this up manually but a nice front end to create/manage them would be handy.. but perhaps asking to much now
