Using Docker compose to deploy WordPress on AWS

This is a diagram that I have used for this lab.

I have explained how to use Docker compose to deploy WordPress on-prem (https://tungle.ca/?p=2381). In this article, I will install docker on the Debian Linux instance on AWS, then deploy WordPress via this docker.

SSH to the machine.

sudo apt-get update

+ Install Docker CE on Debian 10.

apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

+ Add Docker GPG key and Docker repository.

curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"

+ Install Docker Engine.

apt-get update
apt-get install docker-ce docker-ce-cli

+ Enable and start Docker daemon.

systemctl start docker
systemctl enable docker
systemctl status docker

+ Next, use Docker compose to deploy WordPress. Download the Latest Docker Version.

sudo su
curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

+ Change file permission & check the docker version.

chmod +x /usr/local/bin/docker-compose
docker–compose -v

+ Create a sample docker-compose.yml file.

mkdir mywordpress
cd mywordpress/
nano docker-compose.yml
