Hi, is there any documentation or working example regarding the

--container-context

option for

dagster api grpc

? I'm looking for a way to configure the environment of the container launched by the

DockerRunLauncher

. Using

env_vars

within the launcher section of the

dagster.yaml

file is not a viable option for me because I'd like to set different variables for different grpc servers.

Hi Marco - it's a JSON string that can look like this to set env vars in Docker for example:

'{"docker": {"env_vars": ["FOO_ENV_VAR=bar_value", "BAZ_ENV_VAR"] } }'

It's not very well documented currently, we're hoping to move to a place where you set that config in a place like workspace.yaml instead of needing to pass around JSON strings - but it should work for the forseeable future
