Quick and easy to use Docker container for your local Drupal development. It contains a LAMP stack and an SSH server, along with an up to date version of Drush. It is based on Debian Stretch.
This image contains:
- Apache 2.4
- MariaDB 10.1
- PHP 7.0
- Drush 8
- The latest release of Drupal Console (for
8and8.*.*tags) - Drupal 7 or 8 (depending on tag)
- Composer
- PHPMyAdmin
- Blackfire
When launching, the container will contain a fully-installed, ready to use Drupal site.
- Drupal:
admin:admin - MySQL:
root:(no password);drupal:drupal - SSH:
drupal:drupal(root:root)
- 80 and 443 (Apache)
- 22 (SSH)
- 3306 (MySQL)
If you wish to enable Blackfire for profiling, set the following environment variables:
BLACKFIREIO_SERVER_ID: Your Blackfire server IDBLACKFIREIO_SERVER_TOKEN: Your Blackfire server token
You can read more about this image here.
Clone the repository locally and build it:
git clone https://github.com/wadmiraal/docker-drupal.git
cd docker-drupal
docker build -t yourname/drupal .
Notice that there are several branches. The master branch always refers to the current recommended major Drupal version (version 8 at the time of writing). Other branches, like 7.x, reflect prior versions.
Get the image:
docker pull wadmiraal/drupal
You can specify the specific Drupal version you want, like 7.41 or 8.0.0. For example:
docker pull wadmiraal/drupal:7.41
You can also use the latest Drupal version of any major release branch by omitting the minor (and patch) version information:
docker pull wadmiraal/drupal:7
For optimum usage, map some local directories to the container for easier development. I personally create at least a modules/ directory which will contain my custom modules. You can do the same for your themes.
The container exposes its 80 and 443 ports (Apache), its 3306 port (MySQL) and its 22 port (SSH). Make good use of this by forwarding your local ports. You should at least forward to port 80 (using -p local_port:80, like -p 8080:80). A good idea is to also forward port 22, so you can use Drush from your local machine using aliases, and directly execute commands inside the container, without attaching to it.
Here's an example just running the container and forwarding localhost:8080 and localhost:8022 to the container:
docker run -d -p 8080:80 -p 8022:22 -t wadmiraal/drupal
If you want to run in HTTPS, you can use:
docker run -d -p 8443:443 -p 8022:22 -t wadmiraal/drupal
Here's an example running the container, forwarding port 8080 like before, but also mounting Drupal's sites/all/modules/custom/ folder to my local modules/ folder. I can then start writing code on my local machine, directly in this folder, and it will be available inside the container:
docker run -d -p 8080:80 -v `pwd`/modules:/var/www/sites/all/modules/custom -t wadmiraal/drupal
Using Drush aliases, you can directly execute Drush commands locally and have them be executed inside the container. Create a new aliases file in your home directory and add the following:
# ~/.drush/docker.aliases.drushrc.php
<?php
$aliases['wadmiraal_drupal'] = array(
'root' => '/var/www',
'remote-user' => 'root',
'remote-host' => 'localhost',
'ssh-options' => '-p 8022', // Or any other port you specify when running the container
);
Next, if you do not wish to type the root password everytime you run a Drush command, copy the content of your local SSH public key (usually ~/.ssh/id_rsa.pub; read here on how to generate one if you don't have it). SSH into the running container:
# If you forwarded another port than 8022, change accordingly.
# Password is "root".
ssh root@localhost -p 8022
Once you're logged in, add the contents of your id_rsa.pub file to /root/.ssh/authorized_keys. Exit.
You should now be able to call:
drush @docker.wadmiraal_drupal cc all
This will clear the cache of your Drupal site. All other commands will function as well.
Similarly to Drush, Drupal Console can also be run locally, and execute commands remotely. Create a new file called ~/.console/sites/docker.yml and add the following contents:
# ~/.console/sites/docker.yml
wadmiraal_drupal:
root: /var/www
host: localhost
port: 8022 # Or any other port you specify when running the container
user: root
console: drupal
You can now call something like:
drupal --target=docker.wadmiraal_drupal module:download ctools 8.x-3.0-alpha19
You can find more information about Drupal Console in the official documentation.
Note: did you know you can now run tests very quickly without having to maintain a local Drupal instance? Check drupal-run-tests.sh for more information.
If you want to run tests, you may need to take some additional steps. Drupal's Simpletest will use cURL to simulate user interactions with a freshly installed site when running tests. This "virtual" site resides under http://localhost:[forwarded ip]. This gives issues, though, as the container uses port 80. By default, the container's virtual host will actually listen to any port, but you still need to tell Apache on which ports it should bind. By default, it will bind on 80 and 8080, so if you use the above examples, you can start running your tests straight away. But, if you choose to forward to a different port, you must add it to Apache's configuration and restart Apache. You can simply do the following:
# If you forwarded to another port than 8022, change accordingly.
# Password is "root".
ssh root@localhost -p 8022
# Change the port number accordingly. This example is if you forward
# to port 8081.
echo "Listen 8081" >> /etc/apache2/ports.conf
/etc/init.d/apache2 restart
Or, shorthand:
ssh root@localhost -p 8022 -C 'echo "Listen 8081" >> /etc/apache2/ports.conf && /etc/init.d/apache2 restart'
If you want to run tests from HTTPS, though, you will need to edit the VHost file /etc/apache2/sites-available/default-ssl.conf as well, and add your port to the list.
PHPMyAdmin is available at /phpmyadmin. The MySQL port 3306 is exposed. The root account for MySQL is root (no password).
Blackfire is a free PHP profiling tool. It offers very detailed and comprehensive insight into your code. To use Blackfire, you must first register on the site. Once registered, you will get a server ID and a server token. You pass these to the container, and it will fire up Blackfire automatically.
Example:
docker run -it --rm -e BLACKFIREIO_SERVER_ID="[your id here]" -e BLACKFIREIO_SERVER_TOKEN="[your token here]" -p 8022:22 -p 8080:80 wadmiraal/drupal
You can now start profiling your application.
