This is a docker / dokku-alt implementation for deploying your Wordpress applications easily. I have edited the deploy scripts to make sure this works in a real-life applications.

The container is designed to work with dokku-alt, however you should be able to use it independently too. I will provide help for dokku-alt.

You will need dokku-alt installed on your server: dokku.example.com. Clone this repository locally or use dokku clone app-name repository-url.

git clone https://github.com/romaninsh/docker-wordpress.git
cd docker-wordpress
git remote add deploy [email protected]:wordpress
git push deploy master

If everything goes well, you should receive URL. Opening that URL will complain about database connection. Let's set up our database next.

Dokku allows you to set up and configure database easily.

dokku mariadb:create wordpress
dokku mariadb:link wordpress wordpress

Refresh your URL and it should redirect you to standard wordpress install steps.

Wordpress is a CMS and people tend to upload files through wp-admin. In a standard docker install those files will dissapear when you re-deploy your site, because a new container is created every time. To make those files persistent, you'll need to set up a volume.

dokku volume:create wordpress /data
dokku volume:link wordpress wordpress

Because the volume we created was empty, volume-init.sh will automatically move wp-content folder from the default installation to your volume. To confirm that wp-content is linked you can peek inside container logs:

dokku logs wordpress

and it should contain:

Moving wp-content to blank volume..
Linking wp-content..

You can access docker containers from host operating system. Type:

ls -l /var/lib/docker/vfs/dir/

and look for recently created folder. Create symlink to access it easy

ln -s /var/lib/docker/vfs/dir/<your-id-here> wordpress

Inside you'll find wp-content folder which you can customise. In my installations it's often linked with it's own repository. Make sure you back up this volume as it would contain your uploaded files.

This wordpress container comes with default wp-config.php file. If you want to tweak it, copy it to your /data volume, then run:

dokku deploy wordpress

You can also add your own .htaccess file to your data volume and it will be automatically used.

You often would like to access logs from your web server. This container configures your apache to send logs through stdout to docker in a normal way. You should be able to see your logs through:

dokku logs wordpress

If you find that this container is not fully usable in your production environment, I would love to improve it as long as it's not compromise it's simplicity.

Start by forking this repository. Then grab the new repository SSH url and run on your local machine:

git remote add my <url>

Perform tweaks necessary, test them by doing

git push deploy master

and when everything is perfect,

git push my master

Once done, go to your repository on github.com and create pull request. Thank you for your contribution.
