Run commands inside Docker from bat file in Windows about butterfly HOT 9 CLOSED

just do the same thing the Docker Quickstart Terminal shortcut does, but add whatever command to the end:

cd "C:\Program Files\Docker Toolbox"
"C:\Program Files\Git\bin\bash.exe" --login -i "C:\Program Files\Docker Toolbox\start.sh" docker run hello-world

I would like to achieve the same thing.

@novaterata thank you for the reply. This is quite helpful. Do you also have a quick tip about how to initiate a command inside VM after it is open? If I want to pass the command similar to what you proposed then we have to start the VM for every new command?

I ideally need to be able to communicate to VM once it's opened.

http://stackoverflow.com/questions/26639968/boot2docker-startup-script-to-mount-local-shared-folder-with-host look at the accepted answer. It explains the location of a file that boot2docker will run when it starts. This could be your doorway so to speak. You could start a service of some kind here.

@novaterata will do! thanks for the prompt reply.

I don't know if that will work as I've kind of ignored windows docker since I deal with too many SMB shares. Good luck!

Here is my findings so far:

OpenFOAM image is using boot2docker version 1.6.2. boot2docker was deprecated in favor of docker-machine and docker-for-Windows. Here is a useful subcommand comparison.

Nevertheless it is possible to use docker to run commands in a running container in Windows.

1. Use boot2docker shellinit and set the environment based on the output.
2. Once environment is set. You can use docker ps to find container ID for OpenFOAM. Name of the container for the latest release is of_plus_300.
3. The docker exec command runs a new command in a running container. I can create a .sh file in study folder and then I can use docker exec -it [container id] [command] to run it.

The only issue here is that some of the OpenFOAM files and folders are not available to root user. In the newer versions exec -u is available to change the username but not in version 1.6.2.

I tried a couple of solutions such as using sudo su to change the user inside the bash but so far I couldn't get it to work. There is a discussion here that suggests that I can re-create OpenFOAM's environment. I rather to just change the user if possible but if that can't happen then this can be the solution.

This post was very helpful.

I think figured it out! This batch file runs the .sh in case folder that runs blockMesh and snappyHexMesh.

study_room.bat

cd "C:\Program Files\Boot2Docker for Windows"
set DOCKER_CERT_PATH=C:\Users\Administrator\.boot2docker\certs\boot2docker-vm
set DOCKER_TLS_VERIFY=1
set DOCKER_HOST=tcp://192.168.59.103:2376
docker exec -it 63915d16038d bash /home/ofuser/workingDir/butterfly/study_room/study_room.sh

study_room.sh

#!/bin/bash
su - ofuser -c "cd /home/ofuser/workingDir/butterfly/study_room_ver_3; blockMesh; snappyHexMesh"

docker exec does the job. No need to extra .sh file.

@echo off
cd "C:\Program Files\Boot2Docker for Windows"
set DOCKER_CERT_PATH=C:\Users\Administrator\.boot2docker\certs\boot2docker-vm
set DOCKER_TLS_VERIFY=1
set DOCKER_HOST=tcp://192.168.59.103:2376
docker exec -it 63915d16038d su - ofuser -c "cd /home/ofuser/workingDir/butterfly/indoor_airflow; blockMesh | tee /home/ofuser/workingDir/butterfly/indoor_airflow/etc/blockMesh.log"
