Docker WordPress Development on Google Cloud with Cloud SQL. We have covered the details of setting up WP on LEMP stack on Ubuntu 18.04 LTS.
Now, in this tutorial we are going to use EasyEngine to set up WordPress in Docker on Google Cloud and use Cloud SQL for database.
Prerequisites
Make sure you choose Ubuntu 16.04/18.04 or Debian while setting up your Google Compute Engine.
- Up and running Compute Engine, see the Setting up Compute Engine Instance.
- Domain name is pointed to your virtual machine.
- For setting up Cloud DNS, see the Setting up Google Cloud DNS for your domain.
- Google Cloud SQL Setup, see Setup Cloud SQL and connect with Compute Engine.
| Platform | RAM | SSD | Cost |
| Alibaba Cloud | 512 MB | 20 GB | $2.50/mo |
| Cloudways – Managed Cloud | 1 GB | 25 GB | $10/mo |
| Kinsta – Google Cloud Managed WP | 1 Website | 10 GB | $30/mo |
Install EasyEngine
We shall install EasyEngine with the official installer script for Linux. This script will install all dependencies for you.
Go to your Google Cloud Console and navigate to Compute Engine >> VM Instances and SSH to your instance.
Now execute the following commands to install EE v4.
sudo apt update
wget -qO ee rt.cx/ee4 && sudo bash ee
This will take a few minutes to install and setup docker. Once the installation is complete you will receive a confirmation like this below.
+-------------------+-------------------------------------------------------------------------+
| OS | Linux 4.15.0-1026-gcp #27-Ubuntu SMP Thu Dec 6 18:27:01 UTC 2018 x86_64 |
| Shell | /bin/bash |
| PHP binary | /usr/bin/php7.2 |
| PHP version | 7.2.13-1+ubuntu18.04.1+deb.sury.org+1 |
| php.ini used | /etc/php/7.2/cli/php.ini |
| EE root dir | phar://ee.phar |
| EE vendor dir | phar://ee.phar/vendor |
| EE phar path | /home/username |
| EE packages dir | |
| EE global config | |
| EE project config | |
| EE version | 4.0.8 |

Now you can proceed to create a new site.
Set up WordPress in Docker
There are different types of sites that can be created using EasyEngine
- Basic HTML website
- PHP website with database
- WordPress website (Cache, Non-cache, Sub-domain, Sub-directory)
- Multi-site WordPress on Sub-domain or Sub-directory
Now we shall install WP using cache and use Cloud SQL as database.
The command to create a new site is sudo ee site create yourdomainname.com --type=wp
We shall customize the installation with some additional parameters as defined below.
- dbhost => External database host name
- dbuser => Database username
- dbpass => Database password
- dbname => Database name
- admin-email => WP admin Email
- admin-user => WP admin username
- admin-pass => WP admin password
- dbprefix => Database prefix
- cache => Enable Redis cache
- ssl => Install SSL certificate
Now execute the following command to create your WordPress website.
sudo ee site create yourdomainname.com --type=wp --dbhost=CLOUD_SQL_INSTANCE_IP_ADDRESS --dbuser=database_username --dbpass=database_password --dbname=database_name --admin-email=your_email --admin-user=admin_username --admin-pass=admin_password --dbprefix=db_prefix_ --cache
Now you have instructed EasyEngine to create a WP website for your Domain name with Redis cache, Cloud SQL for database and custom login credentials.
Within a few seconds your website will be created with the above details and once the set up is completed you will receive your site details like this.
Configuring project.
Verifying connection to remote database
Success: Connection to remote db verified
Creating WordPress site yourdomainname.com
Copying configuration files.
Starting site's services.
Downloading and configuring WordPress.
+--------------------+------------------------------------------+
| Site | https://yourdomainname.com |
+--------------------+------------------------------------------+
| Site Root | /opt/easyengine/sites/yourdomainname.com |
+--------------------+------------------------------------------+
| Site Title | yourdomainname.com |
+--------------------+------------------------------------------+
| WordPress Username | WordPress Username |
+--------------------+------------------------------------------+
| WordPress Password | WordPress Password |
+--------------------+------------------------------------------+
| DB Host | CLOUD_SQL_INSTANCE_IP_ADDRESS |

| DB Name | Database Name |

| SSL | Enabled |
+--------------------+------------------------------------------+
| SSL Wildcard | No |
+--------------------+------------------------------------------+
| Cache | Enabled |
+--------------------+------------------------------------------+
Now visit your Domain name in your browser, you can see your website homepage.
Great!
Let’s check the admin to verify what is used.
Login to your dashboard with your admin username and password. If you don’t remember the password you can always get your site info.
sudo ee site info yourdomainname.com
As you can see Nginx Helper and WP Redis plugins are activated by default in your installation.
Install SSL Certificate in Docker
Now you can install Let’sEncrypt SSL certificate using EE v4.
sudo ee site update yourdomainname.com --ssl=leOnce this is completed your site will be accessible with HTTPS.
Docker Processes
You can check also the running services inside containers using sudo docker ps

You can see PHP, Redis, Nginx are running inside docker.
You can also check the docker status for memory, cpu and I/O usage.
sudo docker stats

Now your WordPress installed with Docker containers. To learn more abour EE you can get more details by checking their handbook.
Running WordPress inside the Docker is easy now!
