How to launch a Wordpress Server with ssl certificate using docker-compose and Redis

Prerequisites

• Docker
• point domain to the server

Install Docker

Before running the instructions below make sure to check the official Docker installation guide for the latest instructions they may have changed in the meantime.

As of 20-05-2025 this is the script to install docker on Ubuntu 20.04 - 24.04

1- update the apt repository.

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

2- Install docker engine latest

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Setup the server

1- Create a directory for the project

2- Clone this repository there

3- Create a .env file by copying the .env.example and change the values to your needs

4- Create a acme.json file and give it the right permissions

touch letsencrypt/acme.json
chmod 600 letsencrypt/acme.json

5- Launch the container

docker compose up -d

Note this is necessary to play with redis : W3 Total Cache to take advantage of Redis Cache

Notes

removing the comments from the docker-compose.yml file will allow you to use the following features:

• Traefik dashboard
• Traefik verbose logs

#- "--api.insecure=true" --> to enable the Dashboard
#- "--log.level=DEBUG" --> to enable the verbose logs
ports:
  #- "8080:8080" --> to enable the Dashboard

Setting up this same system on a local machine

1- Install Docker Desktop

2- Create a directory for the project

3- Clone this repository there

4- Create a .env file by copying the .env.example and change the values to your needs

5- And spin the dev docker compose file

docker compose -f docker-compose.dev.yml up -d
