In docker-compose there is a .env file which can hold all the properties of used in docker-compose.yml
Is there an equivalent of that in docker run command? I have exhausted the docs and forums but couldn't find any answers.
Here is what I am looking for: Rather than docker run -v /dir1:/dir1 -v /dir2:dir2 -p 80:80 repo/image
run docker run -config config.yml repo/image' with config.yml file holding all the property mappings
One option could be to have the parameters stored in a file and just get the string of the file using cat:
docker run $(cat config.file) repo/image Where config.file content should be something like:
-v /dir1:/dir1 -v /dir2:dir2 -p 80:80 This does seem to be an unfortunate gap. The best workaround I've found is to use docker-compose with a docker-compose.yml file to define the container and all it's flags and then use
docker-compose run your-service-name-here To just run a single one-off container.
Unfortunatelly, it is no way to do this as you describe. However you can add several env config files and merge them to one .env like describe this answer
$ awk -F= '!a[$1]++' first.env second.env > .env
