[Amateur remarks] Build multiple WordPress on AWS using Docker Compose
1.First of all
I built WordPress with EC2, EBS, and MySQL using the AWS free frame, but it is a remarks column when I verified the construction with more efficient Docker Compose. ** Working environment: SSH (ec2-user) is connected to AWS for verification. ** **
2_1. Install docker.
sudo yum install -y docker
Check the version of docker.
docker -v
Docker version 19.03.13-ce, build 4484c46
Run the docker service.
sudo service docker start
2_2. Install docker compose.
I referred to the following site. https://docs.docker.jp/compose/install.html#linux Check the release page of the Compose repository on GitHub. https://github.com/docker/compose/releases Install version 1.27.4.
sudo curl -L https://github.com/docker/compose/releases/download/1.27.4/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
Grant execution authority.
sudo chmod +x /usr/local/bin/docker-compose
Check the version of docker compose.
sudo /usr/local/bin/docker-compose -version
docker-compose version 1.27.4, build 40524192
3_1. Build WordPress using Docker Compose.
I referred to the following site.
Create a local environment where WordPress works using Docker Compose https://codeaid.jp/blog/docker-wp/
3_2. Create a working folder.
mkdir docker_wp
cd docker_wp
3_3. Create an operating environment file (docker-compose.yml).
** Remarks: We will build a total of 3 sites, 2 WordPress sites and 1 phpMyAdmin site. ** **
nano docker-compose.yml
docker-compose.yml
version: '3.3'

phpmyadmin:
depends_on:

volumes:
db_data: {}
** Remarks: Host name, user name, password, database name, ports, etc. are optional. ** **
** Note: If you are connecting remotely, change the user (ec2-user → ssm-user). ** **
sudo su ssm-user
3_3. Execute the following command.
sudo /usr/local/bin/docker-compose up -d
Creating network "docker_wp_default" with the default driver
Creating volume "docker_wp_db_data" with default driver

3_4. Check the status of the container.
sudo /usr/local/bin/docker-compose ps
Name Command State Ports

4_1. Confirm that WordPress and phpMyAdmin have started.
Check the AWS port.
Check each site from the browser.
http://Babrick IP:8000 → WordPress 1
http://Babrick IP:8010 → WordPress 2
http://Babrick IP:8080 → phpMyAdmin
4_2. Perform the WordPress installation.
After setting the WordPress user etc., a trouble occurred after executing the installation. The command in the terminal became unresponsive, so on the AWS EC2 dashboard When I checked the instance, the CPU usage was 99%. When I checked it again after a while, the CPU usage rate had dropped, so I was able to avoid the trouble by restarting the instance.
To log in to docker_wp_wordpress1_1, execute the following command.
sudo docker exec -i -t docker_wp_wordpress1_1 /bin/bash

Postscript
At work, I used VirtualBox etc. to build an environment such as Windows 7 and Wndows 10 in a virtual environment and verified Windows Update etc. We were able to verify that Docker has no OS and can efficiently build multiple sites. In this verification, I was able to realize the work efficiency of Docker Compose.
