Docker compose

1. Prepaere Dockerfile
2. Create image (When Dockerfile is changed, must do this procedure)

   docker compose build --no-cache    

3. Create a specific container and exec it

   # service name is specified in docker-compose.yml
   docker compose run ${compose_service_name} bash

4. Create the set of containers and run it

   # Up
   docker compose up
   docker compose up -d # runs in background
   
   # If nginx service does not run correctly, try some of them
   #   1. Use `--forece-recreate` option
   #   1. Change service name in `docker-compose.yml`
   docker compose up --force-recreate

5. Launch your browser and access to http://localhost:8080

Simple docker sample

# Create
docker run --name ${container_name} -d -p 8080:80 nginx
docker ps

# attach
docker exec -it ${container_id} /bin/bash

# Terminate
docker stop ${container_id}
docker rm ${container_id}
docker container prune # Remove all containers

# Delete image
docker images
docker rmi ${image_name}
