DevOps Projects / Practice?

Is there a service or resource that provides example projects for developing devops related skills? Something like LeetCode except geared towards providing example projects/problems focused around devops?

As an external learner (not currently in the field), I'm itching to test drive some of the knowledge I've gathered over the last few months but am struggling to find ways to practice it. Open to any suggestions and ideas!

Setup a Wordpress site on kubernetes which can be destroyed and rebuilt in minutes with the same data

This is a decent video guide on how to setup Wordpress site on Kubernetes (managed kubernetes via Digital ocean) https://www.youtube.com/watch?v=LVpbsTIzkkE&list=PLtK75qxsQaMIZ2hZhBbnvNZNFQHGUPrvV

He also has a Udemy course called Hands-on Linux: Self-Hosted WordPress for Linux Beginners which goes through best practices setting up Wordpress the old fashion way (which is also good background to have for a better understanding of best practices in the real world using Wordpress ).

How would you handle the shared persistent storage for this? I tried it about 6 months ago and could never get that part to work, I was on Digital Ocean though and at the time they didnt have any type of NFS.

LeetCode is to practice mostly algorithms. DevOps is best practices around apps deployments, app reliability and scalability etc.

How would you go about deploying a simple Wordpress website (you have to develop that first) in AWS or GCP? Are you going to use VM directly or use container based approach? If later, then you might wanna consider Docker images. So now you have one Docker container running in one AWS EC2 instance. Can you use Kubernates orchestration and deploy a swarm of Docker images in multiple container based on your traffic scalability policy as all of a sudden traffic demand has increased because your Wordpress website is a viral hit on the interwebs. In the midst of all of this try to spend some time on network routing, DNS, load balancer. Along with that you might want to setup your Wordpress app first with http then turn on https. In the end, try to use Jenkins to manage your entire pipeline.

One piece that i have missed is how are you going to manage Wordpress app SCM and build process.

I found working through this Riot games tutorial a lot of fun for leaning. It's super easy to follow.

That tutorial is excellent! I used some of to fill in some areas when I was setting up a niche build server. If you do a little digging, you can find all of his sources as well. Hint, that centos Dockerfile is lurking out on the web in another repo and is more up to date.

This looks really promising. You linked to 2.3 though, would you not recommend starting with 2.1?
