docker-container-helper

A command line helper for Docker containers

I got sick and tired of typing docker exec -it $CONTAINER_NAME$ $COMMAND$ every time I wanted to poke inside a container. So I made this.

Right now it looks for a docker-compose file with a container_name variable and executes the command in there.

Requirements

  • Docker installed on your machine
  • A docker-compose.yml file containing a container-name value

Installation:

  • Clone this repo.
  • Make the dockerContainerHelper.sh file executable with chmod +x dockerContainerHelper.sh.
  • Move the file to a directory in your $PATH, such as /usr/local/bin.

If you want more flexibility, create a symlink called container-exec somewhere in your $PATH linked to the dockerContainerHelper.sh file within the repo. This allows you to continue to develop with Git while maintaining the convenience of the command line executable. Plus, Zsh (I think) provides auto-complete for executables in the $PATH, so that's a nifty bonus of using a symlink.

cd $SOMEWHERE_IN_PATH$
ln -s $dockerContainerHelper.sh_LOCATION$ container-exec

Usage

container-exec composer install
container-exec bash
