[Bug] Docker interactive session: "error during container init: exec: "$GRASSBIN": executable file not found in $PATH: unknown"

[lrntct]

Describe the bug

When trying to use a docker image interactively, I get the following error:

docker run -it osgeo/grass-gis:releasebranch_8_4-debian
docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: exec: "$GRASSBIN": executable file not found in $PATH: unknown

This occurs with all the docker images listed on the website

To reproduce

docker run -it osgeo/grass-gis:releasebranch_8_4-debian

Expected behavior

I would expect to be able to use grass in an interactive docker session

Try specifying an entry point too. There is not an entry point specified in the Dockerfile if I remember well, only the CMD. Not all runtimes like that.

You're totally right, calling docker run -it osgeo/grass-gis:releasebranch_8_4-debian bash works fine. I'll close this now.
