This readme help you to build and run the current part of the project. Slides: http://slides.com/adrienfenech/mti-devops/fullscreen
Firstly, build the project
docker build -t username/nodejs_server .
In this command, you specify a tag to retrieve a specific build, and use . to specify that the current directory contains the Dockerfile.
then, run it:
docker run -i -p 80:8080 --name=nodejs_server username/nodejs_server
With this command, you tell docker to keep an interactive mode with -i which lets you execute command if needed. In this case, you can see that the server is running, and simply ctrl + c to kill it if needed.
You also specify you want to bind the port 8080 used by the container (see Dockerfile -> EXPOSE 8080 & server.js which listen on port 8080) with the port 80 of the host (your machine) using the option -p.
Finally, you named your container to easily retrieve it.
After you have launched the container, you can see it running with the command docker ps. You can also list each container you already build & run with docker ps -a and see there current status. Then, you can stop one (docker stop <image_name>) or remove one (docker rm <image_name>).
You can also build and run this project with docker-compose. For this, use:
docker-compose up
This command will build and run each application contains by the docker-compose.yml file. You can also specify option like -d to run the image in detached mode.
For those who are running on Windows, you cannot access to the server via localhost. In fact, the docker-machine on which you are running created a specific environment which can be accessed with an ip address. To find it, use
docker-machine ip
