Download the PHP package visay/dockerwordpress without Composer

DockerWordpress helps you developing Wordpress projects

DockerWordpress creates the necessary Docker containers (webserver, database, php, mail, redis, elasticsearch, couchdb) to run your Wordpress project. The package provides a wrapper script in vendor/bin/dockerwordpress which simplifies the handling of docker and does all the configuration necessary.

We created this package to make development on Wordpress projects easier and to create a simple reusable package which can easily be maintained and serves well for the standard project.

Development will continue further as the package is already reused in several projects. Contributions and feedback are very welcomed.

Install docker

https://docs.docker.com/installation/ (tested with docker v17.03)

Install docker-compose

We use docker-compose to do all the automatic configuration:

http://docs.docker.com/compose/install/ (tested with docker-compose v1.12)

The repository contains a Dockerfile which will automatically be built in the docker hub after each change and used by docker-compose to build the necessary containers.

Install dockerwordpress into your distribution

Add visay/dockerwordpress as dev dependency in your composer.

Example:

Note:

DockerWordpress uses port 80 for web access so you need to make sure that your host machine does not have any software using that port. Usually this happens if you have apache or nginx installed in your host machine, so you can stop it with:

Run dockerwordpress

vendor/bin/dockerwordpress up -d

The command will echo the url with which you can access your project. Add the hostname then to your /etc/hosts and set the ip to your docker host (default for linux is 0.0.0.0). You can also use any subdomain with *.hostname and it will point to the same server. What you need to do is to add exact subdomain name to your /etc/hosts. The parameter -d will keep it running in the background until you run:

vendor/bin/dockerwordpress stop

The default database configuration for your wp-config.php is:

<?php

## Database connection
define('DB_NAME', 'dockerwordpress');
define('DB_USER', 'root');
define('DB_PASSWORD', 'root');
define('DB_HOST', 'db');

Also note that there is a second database dockerwordpress_test available for your testing context. The testing context url would be test.hostname and this hostname should be added to your /etc/hosts too.

Check the status

vendor/bin/dockerwordpress ps

This will show the running containers. The data container can be inactive to do it's work.

Tips & Tricks

Configure remote debugging from your host to container

DockerWordpress installs by the default xdebug with the following config on the server:

xdebug.remote_enable = On
xdebug.remote_host = 'dockerhost'
xdebug.remote_port = '9001'
xdebug.max_nesting_level = 500

So you can do remote debugging from your host to the container through port 9001. From your IDE, you need to configure the port accordingly.

Running a shell in one of the service containers

vendor/bin/dockerwordpress run SERVICE /bin/bash

SERVICE can currently be app, web, data, db, redis, elasticsearch or couchdb.

Access project url when inside app container

As of current docker doesn't support bi-directional link, you cannot access web container from app container. But in some case you will need this connection. For example in behat tests without selenium, you need the url of your site in Testing context while running the tests has to be done inside the app container.

DockerWordpress adds additional script after starting all containers to fetch the IP address of web container and append it to /etc/hosts inside app container as below:

You need to define the default test suite url in your behat.yml to use http://test.project-url and then you can run the behat tests without having to connect external selenium server

Access database inside container from docker host

While you can easily login to shell of the db container with vendor/bin/dockerwordpress run db /bin/bash and execute your mysql commands, there are some cases that you want to run mysql commands directly from your host without having to login to the db container first. One of the best use cases, for example, is to access the databases inside the container from MySQL Workbench tool. To be able to do that, we have mapped database port inside the container (which is 3306) to your host machine through 3307 port.

Access CouchDB

From your host machine, you can access couchdb from web interface or command line:

Web: http://0.0.0.0:5984/_utils/

Cli: curl -X GET http://0.0.0.0:5984/_all_dbs

From inside your app container, you can also access couchdb through the command line:

Attach to a running service

Run vendor/bin/dockerwordpress ps and copy the container's name that you want to attach to.

Run docker exec -it <containername> /bin/bash with the name you just copied. With this you can work in a running container instead of creating a new one.

Check open ports in a container

vendor/bin/dockerwordpress run SERVICE netstat --listen

Wordpress CLI included

From v1.0.1 we support the WordPress CLI. The installation of WordPress CLI must be done on your composer level. Your WordPress composer should look like:

In order to execute WordPress CLI command first to need to access to the App container
