Especially important for folks that spun up clusters with kubeadm, kops, and Kubespray. Please read and test. We’ve tried to give folks the tools and to make K8s.gcr.io as easy to find. Policies and mutating webhooks too!
I think it depends where you are in your career. Is it worth it for you to shell out your money for a cert? Maybe. I know earlier in my career a Red Hat cert opened doors for me (but my employer paid for it to show team competencies). But, now it would be to prove a point or something like beta testing it.
Thank you both for the question and answer. I’ve been trying to figure out when I should be swapping disks in a RAID10 array. I’ll have to tinker with it to get it to work with my RAID controller (PERC H310) but this is exactly what I’m looking for.
I have a desk with a Linux rig right behind me. I use VSCode remote environments most of the time when building containers (which runs over ssh). You could do this with a VM locally too.
I look at it from the deployment solution backwards. I’ve run some pretty intense (for a blog) CI/CD pipelines in the past. But now there are Netlify, Vercel, and others that support a few static site generators. I use Netlify (paying customer) for all my sites now and my SSG of choice is Hugo because it is a single binary that cranks out a full blown static site in less than a second.
You can call a dockerfile whatever you want. You'll need to specify the filename at build. But, the name really doesn't matter. You can call it umptysquat.txt and it'll build you a container.
In the wild, I've seen (case insensitive) Dockerfile (obvs), Containerfile, and Container.
