Migrating an app from Docker Compose to Kubernetes: step 1, proof of concept with Kompose

We start with TellForm, an open source application providing similar functionality to Google Forms or Typeform. The TellForm project already runs on docker-compose and contains several components:

- Nginx proxy in front of web app
- Redis
- Mongo

As a first step to migrating to Kubernetes, we use Kompose to quickly get a proof-of-concept up and running on a local kube cluster.

That's the first real explanation I've seen of how Docker relates to Kubernetes. Great video.

Greate efforts.. niche content that everyone wants but its limited to find

[florianflowfabworx]

okay, thanks a lot - especially for your conclusion. This is my second try to make a SAAS based on Kubernetes out of my Digital Workspace App and I now know that it makes no sense to lose too much time playing around with kompose and better rebuild the yet docker-compose solution to a Kubernetes solution instead of trying to converting it to one...
... especially for the persistent data (user's file uploads plus the database of the instance), I need to find a state-of-the-art solution...

how to migrate postgresql database by changing schemas and without changing users records?

This is a very clear tutorial. But I have a question! We know that docker-compose usually copies the file from the host defined folder to the container defined folder when creating a volume. This way, we can, for example, copy an entire MVC app from /src to /var/www/html. But how can we do that with kubernetes kubemanifests.yaml file? We cannot import any file to our persistent volumes?

Thank you. Very helpful. But, the .env issue may needs some fixes. Otherwise, it can come and bite in the back later

[JerryOmann]

Thanks for this video! But whats about the data in the docker volume? How can we migrate them directly to kubernetes?
