docker_container - container stops without completing the commands

I want to create a docker container on a remote host and then, in a second step build a binary for pgBackRest inside that container.
It fails with the task to create the container, install some packages for the build and then remain to run.

  • name: creating a build-container
    docker_container:name: pgBackRestBuilder
    image: docker.io/rockylinux:8
    volumes:
  • /data/build/:/build
    state: started
    restart: true
    detach: true
    tty: true
    interactive: true
    working_dir: /build
    command: dnf install -y make gcc openssl-devel libxml2-devel lz4-devel libzstd-devel bzip2-devel

become: true

What happens is that the container is being spun up, running for about 90 seconds and then shutting down without (as far as I can tell) having installed i.e. make. I was thinking the detach, tty & interactive options should have made the container to last.

any hint, what I am doing wrong here?

Hi,

I assume that running "dnf install -y make gcc openssl-devel
libxml2-devel lz4-devel libzstd-devel bzip2-devel" is done after ~90
seconds.

You are asking for that command to be run in a container, once that
command finishes, the container exists. That's how Docker works, and it
would behave exactly the same as the module if you start a detached
container from the Docker CLI.

If you want the container to keep existing, you need to use a command
that does not exit.

Basically what you ask the module to do is equivalent to running

  docker run --detach --interactive --tty --workdir /build \
     -v /data/build/:/build --name pgBackRestBuilder \
     docker.io/rockylinux:8 dnf install -y make gcc openssl-devel \
     libxml2-devel lz4-devel libzstd-devel bzip2-devel

on the command line.

Cheers,
