This project is a great starting point for using Docker with an Node/Express project.
The project requires installing VirtualBox and as well as docker-machine.
Virtualbox can be downloaded: https://www.virtualbox.org/wiki/Downloads.
To start you need to create a VirtualBox virtual machine and specify how many CPUs and how much disk space it should have.
$ docker-machine create dev2 --driver virtualbox --virtualbox-disk-size "5000" --virtualbox-cpu-count 2 --virtualbox-memory "4112"The next step is to use Docker Machine's env command to finish your setup:
$ docker-machine env dev2
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://123.456.78.910:1112"
export DOCKER_CERT_PATH="/Users/user/.docker/machine/machines/dev2"
export DOCKER_MACHINE_NAME="dev2"Finish up the setup by running:
eval "$(docker-machine env dev2)"Next, use: docker-machine ls to ensure your new machine is up and running.
Finally, we can setup and build the docker image:
$ cd <your project directory>
$ docker build -t <your tag> .To run your application:
docker run -p 4500:4500 <your tag>We're running locally, so can get the IP that Docker Machine set up for us with docker-machine ip dev2, and then visit that :4500/docker and we'll get a response.
