docker-dev: Utilities to use Docker in development environments

docker-dev optimises Docker and Docker Compose for use on a developer's computer, making some common tasks easier than they would be otherwise.

Once you've cloned or downloaded this project, you can enable it by adding the following line to ~/.bashrc:

source /path-to-dockerdev/dockerdevrc

Commands

The following Bash scripts are included:

docker-dev

docker-dev wraps some Docker Compose subcommands in order to pass extra arguments. It's not opinionated about the structure of your Docker Compose file, and you can switch between docker-dev and docker-compose.

docker-dev supports autocompletion in a Bash session.

docker-dev build [EXTRA_ARGS...]

Wraps docker-compose build, and also:

  • Avoids leaving intermediate containers behind.
  • Pulls the latest version of any parent Docker images.
  • If an executable file called .dockerdev-prebuild exists in the current working directory, it'll be run before running docker-compose build (unless the executable fails).

docker-dev run [EXTRA_ARGS...]

Wraps docker-compose run to prevent leaving containers behind once the command ends.

docker-dev up [EXTRA_ARGS...]

Wraps docker-compose up and prevents leaving containers behind once the command ends and to exit once any of the services explicitly called exits.

docker-dev up2 [SERVICES...]

Experimental: This subcommand is expected to replace docker-dev up eventually, and it will be changed or simply removed in future releases.

This subcommand wraps docker-dev up and works around limitations in Docker Compose when the services you want to run depend on other services -- namely:

  • Logs from dependent services are output in the foreground.
  • Terminating the docker-dev process also terminates dependent services.
  • Likewise, when a dependent service terminates, all the other services and the parent process are terminated.

docker-dev down

Runs docker-compose down so that all the resources in the project are removed.

docker-clean

This command will remove all your Docker resources (e.g., containers, volumes), except for images created in the past week.
