docker-hat

docker-hat

A hat for your Docker!

This is a set of helper commands to run and manage Docker containers on OS X.

Requirements

• Homebrew
• VirtualBox
• Node.js (>= 0.12)
  • Automatically installed if installing via Homebrew!

Installation

Super simple with Homebrew, just run the below and you'll be up-and-running in no time:

brew tap chinthakagodawita/homebrew-dh
brew update
brew install docker-hat

Commands

All commands are simply sub-commands of the dh binary. A full list is below (examples coming soon!):

dh init

Sets up Docker to run on your Mac. This goes off and sets up (via dinghy) the following things:

• Docker host VM (boot2docker): To run your containers in, docker-machine is used to instrument this
• NFS server (unfsd): So that files can be shared to the container without being bottlenecked by VirtualBox's shared folder implementation
• DNS nameserver (dnsdock): Creates a wildcard DNS on *.docker which automatically maps to the Docker host

Usage

dh init

dh soe

Starts up a nifty Standard Operating Environment for building various applications in. Currently only supports PHP (with special focus on Drupal & Wordpress) but more coming soon!

See the docker-containers repository for a full list and Dockerfiles.

Subcommands

dh soe start

Start up a new container using one of the special pre-built SOE images.

Usage

dh soe start <container-name>

dh soe stop

Stop an already-running container.

Usage

dh soe stop <container-name>

dh soe restart

Restart a running container using the same settings it was started up with.

Usage

dh soe restart <container-name>

dh soe drush

Run Drush inside on of your running containers. Sets up paths correctly so that it executes on your docroot.

Usage

dh soe drush <container-name> [command]

dh host

Controls your Docker host virtual machine and environment.

You shouldn't normally need to start or stop this manually—it should be brought up when required. This command is there for all the times it refuses to listen.

Subcommands

dh host start

Start the Docker host virtual machine.

Usage

dh host start

dh host stop

Stop the host.

Usage

dh host stop

dh host restart

Restart the host.

Usage

dh host restart

dh host status

Show Docker host status.

Usage

dh host status

dh exec

Run a command (any command!) in a container.

Usage

dh exec <container-name> <command>

Example

dh exec foo tail -f /var/log/apache2/error.log

dh shell

Attaches a bash shell to one of your containers and gives your full interactive control. Simply type exit to close.

Usage

dh shell <container-name>

Example

dh shell foo
