Docker environment variables

[itxtoledo]

I don't find in documentation any available environment variables for docker. I need for example limit memory usage.

Hi @itxtoledo, yes you are right that we do not have any examples nor explanation here: https://www.dragonflydb.io/docs/getting-started/docker
or here: https://www.dragonflydb.io/docs/getting-started/docker-compose @Niennienzz worth opening an issue about it and adding some examples on how to add command line arguments to docker or docker-compose.

but you can add regular arguments like this: docker run --network=host --ulimit memlock=-1 docker.dragonflydb.io/dragonflydb/dragonfly --maxmemory=8GB

Would Dragonflydb not support reading environment variables in addition to passing parameters via the command line?

We actually do support reading environment variables!
Just set DFLY_x (where x is the exact name of the flag, case sensitive) and you should be good to go :)

i.e. something like docker run --network=host --ulimit memlock=-1 -e DFLY_maxmemory=8GB docker.dragonflydb.io/dragonflydb/dragonfly

It worked, thank you very much, but this could be in the documentation to save you time

Great! Indeed, I'll add this to our README.
