Build Docker Image

• Docker build commad: docker build -t ansible . [--build-arg USER=$USER]

• Run ansible container: docker run -it ansible ansible

• docker run --mount type=bind,source="$(pwd)"/ansible,target=/home/$USER/ansible -v ~/.ssh:/home/$USER/.ssh:ro --rm -it --name ansible ansible /bin/bash

  • this command mount ansible folder and .ssh folder

  • if using mount option, the ansible folder in host must be created before running the command

  • using bind, the ansible folder in host will be owned by current user, using -v (volume), the username in host will be owned by root
