General Step to Dockerizing a Project

• Tools
  • Online Tool to test docker quickly
  • podman-desktop
  • portainer for linux
• Create a dockerfile
• Create .dockerignore to make docker ignore some files such as node_modules
  • By this step you can build and run the container
• If multiple docker need to be coupled together add docker-compose.yml
  • By this step you can run multiple containers
  • 6. docker compose

How to Run a Docker Project

1. Build the image

docker image build -t zekaryas/projectName .
#docker image build -t{tag or name} name_of_the_image .{where the dockerfile is}
# . means in the current directory

#list images we have
docker image ls

2. Run the image

docker container run -d -p 80:8080 zekaryas/projectName
# -d = detached: run in the background
# -p = port mapping public_port:container_exposed_port

# list containers and their information {id, state{running, exited},name}
docker ps

3. Manage the container

Once we have container we can stop/start/restart it using its id

docker stop [container_id]
docker restart [contaier_id]
docker start [container_id]

How to Run a Docker-Compose Project

1. Build the image(s)

docker-compose up -d --build

# -d = detached background
# --build = build images

docker-compose ps
# Lists containers and their state 

2. Managing docker-compose

docker-compose stop
docker-compose start
docker-compose restart

3. Remove docker-compose containers and their contents
   • Stops containers and removes containers, networks, volumes, and images created by up.

docker-compose down
