Docker run -p -d /node-web-app. Print the output of your app: $ docker ps $ docker logs Running on If you need to go inside the container you can use the exec command: $ docker exec -it /bin/bash.

Step 1 - Create a simple nodejs app
First, you should initialize a new package
and install express framework.
Good. Now you have package.json file with express as a dependency in it. Here is hello world nodejs app in a single file server.js
Good. We have a nodejs app. To test it you can run:
The app should be availbale on http://localhost:8080
Step 2 - Make a docker container
Now let's copy a Dockerfile from official Nodejs website.
We don't want a node_modules folder in our docker container. All dependencies should be installed from scratch. Let's create a .dockerignore file and prevent node_modules from copying to the container.
Done with files. This is your files structure:
Now let's build the container:
You can try to run it:
Result should be the same:
Step 3 - Push to cloud
In order to install node js docker container, create a new app via cli or admin panel and set a port to 8080.
Now just push the container:
Done. The link to app is in control panel.
Bonus 1: SSL certificate for HTTPS
Node Yarn Docker Box
It's already done for you. If you need to connect your custom domain, SSL certificate will be provided for it.
Bonus 2: Autoscaling
With autoscaling the app will be scaled up when CPU and RAM load goes up and scaled down when it goes down.
Logs and app status
Docker Yarn Cache
Now you can deploy nodejs with docker without a massive build time.
