I read this How does docker compare to openshift?

But I have a question : This is an extremely simplified description of what usually devs do with Openshift :

1. Select a "pod" (let's say a JBoss/Wildfly container)

2. From within Openshift you point to your github repo

3. Openshift would clone the repo, build it and deploy it

4. Openshift present you with a web URL to access this repo port 8080

There's of course a lot more going on but that's as simple as it gets

Is this setup doable in my own linux box, VM or a cloud instance (Docker Container --> clone, build and deploy from git repo)? What would I need without messing too much with networking and domains etc?

from my research I see the following tools:

1. Kubernetes

2. Dokku : I see it described as "Your own Heroko"

I also keep hearing about CaaS (Containers as a Service)

I understand I would be needing another tool or process to the build (CI/CD) capability, and to triggering builds with git push.
