Putting a UI around Docker with Portainer

But one goes deep into how to set it up with deep integration on Docker Machine and DigitalOcean on a more expert level.
While the other provides a very simple beginner level Play with Docker setup and then goes on how to install an entire application stack, with frontends, databases and workers.
Most of these solutions/management UIs/etc. focus on delivering some form of simple stack management, metrics, and infrastructure provisioning, but one thing I've yet to see is application lifecycle management (this is not a criticism of Portainer, more of an overall gap in the market I think needs addressing).
I'd love to see something with more obvious CI/CD hooks and a good UI that let me follow the build and deployment status of an entire stack -- this may not seem like a good direct fit for the likes of Portainer, but after a few deploys you'd probably like to have comparable metrics between releases, etc.
