Docker Deployment steps

• Building your image

Go to the directory that has your Dockerfile and run the following command to build the Docker image. The -t flag lets you tag your image so it's easier to find later using the docker images command:

  docker build . -t node-web-app

• Your image will now be listed by Docker:

  docker images

• Run the image Running your image with -d runs the container in detached mode, leaving the container running in the background. The -p flag redirects a public port to a private port inside the container. Run the image you previously built:

  docker run -p 3000:3000 -d node-web-app

• Get container ID

  docker ps

• Print app output

  docker logs <container id>
