Docker-compose setup for Wordpress

Dockerized Wordpress Setup for Cloud VM

This setup includes:

• Mariadb 10
• Wordpress 5
• Nginx for reverse proxy and SSL
• Let's Encrypt SSL certificate

System Requirements

1. Memory usage

   This setup can run reliably with memory usage < 1G. If using EC2 on AWS, choose the micro size.

2. Disk space

   This really depends on how much you want to put on your website. The default option for EC2 (8GB) may not be enough. I just went for 30G and it should last me a long time.

   Alternatively, consider setting up an OS disk and a data disk, and mapping /var/lib/docker to the data disk.

Prerequisites

1. Docker and docker-compose are installed

2. DNS record pointing to your VM

3. aws CLI

Also check out my cloud-init setup here.

Installation

1. Clone this repo

2. Run install.sh with the following environment variables:

   • INSTALL_DIR: the docker-compose directory that you will be using
   • WP_HOSTNAME: the hostname of your website (= DNS record)
   • COMPOSE_PROJECT_NAME: project name; optional, default to basename of INSTALL_DIR

   You may run the command like this:

   INSTALL_DIR=<install dir> WP_HOSTNAME=<hostname> COMPOSE_PROJECT_NAME=<project name> ./install.sh
   

   You will be prompted during SSL certificate generation.

3. Add a cron job to renew your certificate (see below)

4. Add a cron job to backup your website (see below)

Alternative installation without SSL

(If you know what you are doing...)

Use install-no-ssl.sh instead.

Certificate renewal

To manually renew your certificate, go to your INSTALL_DIR and run

bin/renew-cert.sh

To reload Nginx after renewing the certificate:

bin/nginx-reload.sh

You may set up a cron job to automatically renew your certificate.

Backup

You must have aws CLI installed, and an s3 bucket accessible from your VM. If you are using EC2, the easiest way is to attach an IAM role to your VM.

To manually backup your website, go to your INSTALL_DIR and run

sudo bin/backup.sh <s3 bucket name>

The backup will include:

• Your installation folder
• All docker volumes in your installation

You may set up a cron job to automatically backup your website.
