#oci #oraclecloud #wordpress #docker

Introduction

Oracle cloud provides free resources. You can follow the steps below to host your WordPress website on OCI for free.

Environment

Ubuntu Server
Docker and compose plugin
Domain name

Installation

Step-1: Create compute instance

I’ll continue with the manual installation to go through the steps in case you want to install it manually. In the web console, click the navigation menu on the upper left side and select Compute > Instances. Click on Create Instance. I’ll choose the name "wordpress" and Ubuntu 22.04 Minimal.

Step-2: Install Docker Engine on Ubuntu

https://docs.docker.com/engine/install/ubuntu/

sudo apt-get update

sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

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

Step 3: Manage Docker as a non-root user

root> sudo usermod -aG docker ubuntu
root> newgrp docker
ubuntu> docker ps

Step 4: Configure Docker to start on boot with systemd

sudo systemctl enable docker.service
sudo systemctl enable containerd.service

Step 5: Get free domain name from freenom.com

Target: Ubuntu compute instance Public IP address

Step 6: Create docker-compose.yml

mkdir -p ~/wordpress/ && cd ~/wordpress/
vi docker-compose.yml
