| Summary | 0003423: Cannot run command in container from host | ||||
| Description | Hello, apologies if this is my error. I am trying to start the docker container and run a command. docker run -ti --rm -e DISPLAY= -u0 -u 1000:1000 -v /tmp/.X11-unix:/tmp/.X11-unix -v /home/elm/OpenFOAM/elm-7:/home/openfoam -e XAUTHORITY=/home/openfoam/.Xauthority -v :/home/openfoam/.Xauthority openfoam/openfoam7-paraview56 ./mm Ideally the "openfoam7-linux" script would be updated to include an option for running a command. Many thanks! | ||||
| Steps To Reproduce | 1. Create /home/elm/OpenFOAM/elm-7 2. cd /home/elm/OpenFOAM/elm-7 3. create file mm with the following text: #!/bin/bash echo 'Bite me' > ~/mm2.txt 4. chmod 744 mm 5. Run with docker run -ti --rm -e DISPLAY= -u0 -u 1000:1000 -v /tmp/.X11-unix:/tmp/.X11-unix -v /home/elm/OpenFOAM/elm-7:/home/openfoam -e XAUTHORITY=/home/openfoam/.Xauthority -v :/home/openfoam/.Xauthority openfoam/openfoam7-paraview56 ./mm | ||||
| Additional Information | Docker version 19.03.5, build 633a0ea838 (have also tried version 18) Tried on 2 different host machines. (one running debian testing, one running debian stretch). Tried openfoam/openfoam7-paraview56 and an openfoam6 container. Tried removing the -ti, removing -rm. Tried adding sleep 5 after the echo line in mm. I looked at entry.sh in root of the container and the last exec line seems to be correct but does it get the command from docker? If I type exec /bin/bash mm in the running container the script runs correctly and the container exits. If I try a completely different container (not from openfoam.org) things work as expected. | ||||

Have decided to keep the container running. So will start with openfoam7-linux And will run processes by finding conatiner id with: docker container ls Then exec script with: docker exec -it $CONTAINER_ID /home/openfoam/mm |

Not a bug. The entry script is designed to launch an interactive shell. You can't pass non-interactive commands to it. If you want to run the instance with a command, just bypass the entry script alltogether. Add "--entrypoint ./mm" to your launch command instead of just "./mm". |
