OpenShift is (arguably) the best PaaS Kubernetes distribution, and certainly the most enterprise-ready one. I use it in production and it's a great piece of engineering. They heavily contribute back to Kubernetes upstream instead of forking it. Red Hat is responsible for many important Kubernetes features like RBAC.
They acquired Ansible and, recently, CoreOS.
Software Collections make it really easy to run an up-to-date software stack on RHEL by decoupling it from the base OS (which is the way to go, IMO).
And of all the IdPs I recently evaluated, Keycloak sucks the least.
How does SmartOS solve this?
Also, does the Joyent stack have an OpenShift equivalent? Triton wants my credit card details to sign up with their public cloud, but I might grab a spare box and give it a try.
...if after reading that you still have specific questions, ask.
You don't need a credit card, if you don't want to run it on Joyent's servers, you can run Triton for free on your own at home, at work, (or someone else's) infrastructure. All of that technology is freely available at Github at no cost other than reading a little bit of documentation and investing some time to set it up following the instructions.
Out of curiosity, do Digital Ocean, Hetzner, Azure or AWS not ask for a credit card?
