Drone + Docker + Node "Hello World" Example

This repository gives you a quick introduction to getting docker running with Node. It is intended for the Docker beginner.

You can adapt the same approach to other languages but I chose Node because it's what I use most often.

Setup

First, checkout this project locally and then follow these steps:

0. Go through the Docker installation and getting started guide before you start.
1. Install the Docker Toolbox.
2. Start a "Quickstart Terminal" session (see the getting started guide).
3. Build the Docker image: docker build -t hello-world .
4. Run the image in a container: docker run -d -p 4001:4000 hello-world

• The -d flag says to run the container in the background (daemon mode).
• The -p flag maps port 4000 from the container to port 4001 on the docker machine.

5. View your new container: docker ps -a
6. Check the logs for your container: docker logs <container-id>
7. Check the port of the container: docker port <container-id>
8. Open the app running on the docker machine: open http://$(docker-machine ip default):4001

Notes & Tips

• If you make changes to your application, you will need to rebuild your image and restart your container.
• The docker-machine command controls the virtual machine that is running Docker on your machine.
• View logs for a docker container: docker logs <container-id>
• List the running containers: docker ps -a
• List all local images: docker images
• Remove an image: docker rmi <image-id>
• Remove a container: docker rm <container-id>
