Killercoda offers free environments (based on Ubuntu) with various tools for beginners to try hands-on. It also has the Kubernetes playground which provides control plane server access for 1 hour. In which we can try to practice hands-on with control plane components. Because sometimes we are dependent on training platforms to try the control plane (or kubeadm) practice, and killercoda comes handy as a free... - Source: dev.to / about 1 year ago

Https://killercoda.com/ has a few scenarios. Source: about 1 year ago

I think killercoda is pretty cool, they don't have a lot of scenarios yet but it does create them like killer.sh does. You can even submit scenarios! Source: over 1 year ago

Killercoda has free labs, I recommend doing those. And there are a few other sites offering paid practice exams or even question dumps, but some of those seem sketchy. I'd personally stick to KodeKloud, killer.sh and Killercoda. Source: over 1 year ago

Since we're here. What do people use when they need to test their software installs well on naked Ubuntu Server of some version? To not do manual setup in VMWare, can be Linux-only. I've found Multipass https://multipass.run/ by Canonical and I wonder if anyone recommends it. - Source: Hacker News / 9 days ago

Multipass I love Multipass for quick Ubuntu instances spun up for testing or as a playground. Wish I would have known and used of it sooner. - Source: dev.to / 3 months ago

I have been using Multipass [0] for a while and it works great to quickly spin up an Ubuntu environment on my MacBook. It supports cloud config in case you want a custom instance. It seems to be limited to running Ubuntu instances only (at least, I haven't figured out how to run other Linux instances) but if you want a quick clean Ubuntu VM I would recommend it. 0: https://multipass.run/. - Source: Hacker News / 5 months ago

I would be cautious or even distrustful of using anything from Oracle. VirtualBox components come under three different licenses - GPLv2, personal use & evaluation license, and an enterprise license. Their VirtualBox license FAQ [1] gives them enough leeway to change future licenses at will. If an exploit is discovered in your old VirtualBox and they've changed the license, you're out of luck. We've moved our... - Source: Hacker News / 11 months ago
