After installing Docker, remember to configure the service to automatically start

chkconfig docker on ; systemctl enable docker ; service docker start

Add your docker user to the docker group:

usermod -a -G docker ec2-user

In order to create one container via CLI this command below will be the equivalent of the compose file further below.

docker create \
  --name=webserver --net=host -e VERSION=latest \
  -e PUID=$(id -u docker) -e PGID=$(id -g docker) \
  -v /var/www/html:/app:ro \
  --restart unless-stopped nginx
docker start nginx

docker-compose.yaml

version: '2'
services:
 myproject:
   container_name: webserver
   build: ./
   volumes:
     - /var/www/html:/app
   restart: always
   network_mode: host

If using the compose file above, the container can be executed using:

docker-compose up -d

In order to monitor the status of running containers, run:

docker stats

If you need to get rid of all images:

docker system prune -a

In order to troubleshoot the container, you can attach to a shell using:

docker run -it webserver /bin/bash
