Junior DevOps test job

The developers gave you a web application written in node.js. The source code is located in this repository, in the app folder. The application listens on port 3000 and responds to HTTP requests with Hello, World

You need to package this application into a docker image and create a configuration to deploy it to a server using docker-compose. The application on the site must be located in the virtual directory /foo, to access it, addresses like http(s)://domain_name/foo will be used. Use specialized docker images for application packaging and deployment.

The result, namely: a Dockerfile for creating a docker image, a docker-compose.yml file, and other files, upload to a personal repository on github.com and send us a link.

Deployment involves the following sequence of commands:

$ git clone https://github.com/YOUR_NAME/REPO_NAME.git
$ cd REPO_NAME
# docker-compose up -d

Deployment testing

$ curl http://localhost/foo

Optional conditions, but we expect you to complete them.

  • Make access to the application only via https protocol, when accessing via http, a redirect to https should occur. For the site, use self-signed certificates, put them in the repository along with other files.

  • Launch two containers with the application on different ports and set up balancing of incoming requests to the site to these application instances.
