How to setup a Flask app using Docker as a standalone website

Question

Hello,

I’m reaching out with respect to a problem I had earlier and am now taking a new simpler approach. I have a dockerized Flask app that I want as a standalone web page.

I followed this great guide here to spin up a droplet with a Flask app on it through Docker.

https://www.digitalocean.com/community/tutorials/how-to-build-and-deploy-a-flask-application-using-docker-on-ubuntu-18-04#step-1-%E2%80%94-setting-up-the-flask-application

I want to essentially do this and have it be a subdomain of a site I already own. Say my site is mysite.us and I want this droplet to be @ demo.mysite.us

How would I go about setting that up? Thanks!

Hi there @frankieguz,

Yes indeed, it should be enough to point your domain name to the Droplet’s IP address in order to get it pointed to your Flask application.

In case you wanted to add an SSL certificate, then you could use Nginx as a reverse proxy to handle the SSL termination, or use Cloudflare with Flexible SSL instead.

Regards,
Bobby

Thanks! This guide using Node instead of Flask should be appropriate right? [https://www.digitalocean.com/community/tutorials/how-to-secure-a-containerized-node-js-application-with-nginx-let-s-encrypt-and-docker-compose]

Secure your containerized Node.js application by following this tutorial, which shows you how to deploy a Node.js application with an Nginx reverse proxy using Docker Compose. You will obtain certificates for your application domain with Let's Encrypt and ensure that your application receives a high security rating.
