Docker make .sh executable and run it

docker cmd run shell script
docker entrypoint
dockerfile run shell script
docker run command
docker run sh permission denied
docker build-arg
docker run sh
docker build command

I'm trying to give executable permission to my script inside docker image and run it. I don't want to set chmod + x for it in Dockerfile. i tried

docker run img /bin/bash -c "chmod +x ../test/test.sh; ../test/test.sh

but i got "/bin/bash: bad interpreter: Text file busy"

and i can't just make two containers with this commands:

docker run -d img chmod +x ../test/test.sh

docker run -d img ../test/test.sh

=> starting container process caused "exec: \"../test/testing.sh\": permission denied"

i need somehow bind this two containers together

Text file busy means that something is already using the file.

Normally this would work

docker run --rm -it alpine sh -c 'echo "echo it works" > test.sh && chmod +x test.sh && ./test.sh'

With the second command you create two new containers, that are completly seperate. If you want to execute something in an running container you can use docker exec -it <container id or name> <command e.g. bash>

You don't need to set perms if you just pass your script as parameter:

How to use an entrypoint script to initialize container data at , Use a shell script as the ENTRYPOINT of a container, and execute the necessary setup steps before passing control to a long-running process. Create a shell� docker run creates a container instance of the maven:3.3.3-jdk-8 image. It executes the command mvn install inside of the container. In principal, this cannot influence your system;

Ok, i've figured it:

first i made a container:

docker run --name CONTAINER -dt IMAGE

then exec my commands:

docker exec CONTAINER chmod +x ../test/test.sh 

docker exec CONTAINER ../test/test.sh

docker exec, COMMAND should be an executable, a chained or a quoted command will not work. b" will not work, but docker exec -ti my_container sh -c "echo a && echo b " will. This will create a new file /tmp/execWorks inside the running container� I'm trying to give executable permission to my script inside docker image and run it.

You can try as temporal workaround (not elegant!) to add a "sleep 1" instruction between the chmod and the execution.

Have a look to this thread: "dockerfile" text file busy

Docker Tip #86: Always Make Your ENTRYPOINT Scripts Executable, RUN chmod +x docker-entrypoint.sh ENTRYPOINT ["/app/docker-entrypoint.sh"]. Now your ENTRYPOINT will always be executable and it will� Also, I'd recommend creating a sub-folder to place your content into. If nothing else, it keeps things tidy. Make sure you mark the script as executable using chmod. Here, I am creating a scripts sub-folder to place my script into and run it from: RUN mkdir -p /scripts COPY script.sh /scripts WORKDIR /scripts RUN chmod +x script.sh RUN script.sh

Docker 'run' command to start an interactive BaSH session � GitHub, Docker. # Assuming an Ubuntu Docker image. $ docker run -it <image> /bin/bash an executable and the latter is detected by searching $PATH for an executable with the name bash . Is there a form of this I can use to log into github as part of the "docker build . docker run -it --entrypoint /bin/sh for the images w/o bash. I'm using Docker on MacOSX (with Boot2Docker). I can run images from Docker Hub. However, when I try to run one of my own images like this: docker run -P mylocalimage or. docker run -P mylocalimage bin/a3-write-back or I get: docker "env: can't execute 'bash': No such file or directory"

Dockerfile Cheat Sheet, FROM can appear multiple times within a single Dockerfile in order to create multiple RUN <command> (shell form, the command is run in a shell, which by default is /bin/sh -c on Linux or cmd /S /C on Windows); RUN ["<executable>",� When you use the RUN command, it will execute the instruction and will create a new layer. RUN command can be used in two forms: Shell form RUN <command> Exec form RUN ["executable", "param1", "param2"] CMD. CMD instruction allows you to set a default command and default parameters which will be executed when docker is run.

Error when running Docker with entrypoint script in Linux VM, Error when running Docker with entrypoint script in Linux VM caused "exec: \" docker-entrypoint.sh\": executable file not found in $PATH". This won't work if your image has a defined ENTRYPOINT. For these cases use: docker run -it --entrypoint /bin/bash <image>

  • the thing is nothing uses it- i've tried to create new image and use this command- it returned with that err. it can be only used by chmod command(i replaced chmod command before semicolon with echo and got "permission denied". i've also tried docker run -d img chmod +x ../test/testing.sh and then docker exec -it container ../test/testing.sh - and i got Container container is not running.. despite the detached mode of my container with chmod..
  • The container exits after docker run -d img chmod +x ../test/testing.sh because there is no process running and you have to use chmod if you don't want to use sh test.sh. Can you post the Dockerfile to look why it is not working
