docker-compose-nodejs-example

An example of Nodejs and Mongodb servers built using Docker Compose

Good example here of loading a database fixture: https://stackoverflow.com/a/33397913/25868

To run the Node.js server on your dev pc:

PRE-REQ: You need MongoDB installed to run this directly on your dev PC.

Clone or download this repo, open a command line, change to the repo directory, then install dependencies:

cd web
npm install

Then run the server:

npm start

Now navigate your browser to http://127.0.0.1:3000/ to view the app.

To view the REST API navigate your browser to http://127.0.0.1:3000/data.

Ensure you have VirtualBox and Vagrant installed.

Bring the VM up:

vagrant up

Or run the batch file to record the log to a file:

vm-up.bat

This starts an Ubuntu VM, installs Docker and Docker Compose, then automatically runs docker-compose up to start the system.

At the end you should be able to browse to http://localhost:3000 on your dev workstation and see the web page it produces.

After you reboot the Vagrant VM the system will no longer be running. To restart it, first shell in:

vagrant ssh

Then change to the shared directory:

cd /vagrant

Then run Docker Compose:

sudo docker-compose up -d

The -d parameter starts it detatched from the command line.

To rebuild image (say after changing the code):

sudo docker-compose up --build -d

To list running containers:

sudo docker-compose ps

To kill the containers:

sudo docker-compose kill

For a particular container run:

sudo docker exec -it <container-name> bash

For example, the db container:

sudo docker exec -it db bash

Warning don't try this at home kids:

#!/bin/bash
# Delete all containers
sudo docker rm $(sudo docker ps -a -q)
# Delete all images
sudo docker rmi $(sudo docker images -q)

sudo docker-compose logs

Note: This won't get you a production ready system. I'm still trying to figure out how to do that with Kubernetes.
