• Run nginx

  • in foreground
    • docker run -p 81:80 --name web nginx
  • in foreground and removing it when stopped
    • docker run -p 81:80 --name web --rm nginx
  • in background
    • docker run -p 81:80 --name web -d nginx

  • foreground, mounting the nginx/html directory:

    docker run --rm \
    -p 81:80  \
    --name web \
    --mount type=bind,source=$PWD/nginx/html,target=/usr/share/nginx/html \
    nginx
    

• Enter the container:

  docker exec -it web /bin/bash
  

• Build a local image from the Dockerfile

  docker build -t osinet/nginx:latest .
  

• Run the newly built image:

  docker run --rm \
  -p 81:80 \
  --name web \
  --mount type=bind,source=$PWD/nginx/html,target=/usr/share/nginx/html \ 
  osinet/nginx
  

• List images

  • All except intermediates: docker images
  • All including intermediates: docker images -a
  • Images with this name: docker images osinet/nginx

Step 2: node

cd nginx/node
docker build -t node-app .
docker run -p 8888:8888             \
  -v $PWD/node/src:/usr/src/app/src \ 
  --name voting-node                \
  node-app
