Preparing your environment

We need to edit our hosts file so our machine recognize the traefik domains we will be using. As ou can see in the docker-compose.yml, traefik is using localhost.node and localhost.phpmyadmin.

Edit your hosts file with the following command:

sudo nano /etc/hosts

Then, add these lines:

127.0.0.1 localhost.node

127.0.0.1 localhost.phpmyadmin

Save and exit.

Running your server

• Install node dependencies:

cd app && npm install && cd ..

• Create the docker network used by the containers:

docker network create node

• Then run your server with:

sudo docker-compose up

• Or run it in the background with:

sudo docker-compose up -d

Stopping your server

• To simply and gently stop:

sudo docker-compose stop

• To discard everything changed in the cointainers and reset them:

sudo docker-compose down
