Docker for Dev

Installation

Follow the instructions in install/INSTALL.md.

Run the global containers

We have two containers that will run globally, apart from any project.

1. mysql - you'll have one server that you can reference from all your projects
2. nginx proxy - all requests will go through this proxy, which maps domain names to running containers

Start these by running the start script:

./start.sh

Stop them by running the stop script:

./stop.sh

The first time you start it, it may take a while as it downloads or builds the containers you need.

Open a shell in a running container

Get the name of your container. E.g., "global_mysql_1". Then run:

docker exec -it YOUR_CONTAINER /bin/sh

Or shorten this by adding the following to your .bash_profile:

dsh()
{
  docker exec -i -t $1 /bin/sh
}

Then, to open a shell in a container:

dsh YOUR_CONTAINER

You'll find yourself using this on occasion to get a shell in a running container to run WP CLI, for example.

Connect to your mysql server

Using a tool like Sequel Pro, you can connect to your mysql server much like you would with a locally hosted mysql. The container's port 3306 is mapped to your local port 3306.

Host: 127.0.0.1
User: root
Password: password

In your WordPress config, change the host name to mysql.

Connect to your memcached server

Each project will run its own memcached container. From your WordPress config, set the host to memcached:11211.

To access it from your local system, find the port number by checking docker ps. You might see a number like "32976". Use that port to connect to the server. E.g.,

telnet 127.0.0.1 32976
