This is Gerhard’s first set of interviews from KubeCon North America 2021.
William Morgan shares with us some of the finer Linkerd details, such as the underlying security theme, why native Kubernetes objects are preferable to more CRDs, and the joy of meeting team members in person.
Frederic Branczyk speaks about Parca, a new continuous system profiling tool that uses eBPF to help you understand what is happening on your hosts.
Andrew Rynhard gives us a great Talos OS and Kubespan perspective, and shares some really good follow-up videos on these topics.
The last conversation is with David Flanagan - you know him as Rawkode - about new beginnings. It’s only been less than two months since we’ve had him in episode 18, and he kept really busy. Caleb, his 3 weeks old baby boy, was the youngest attendee at this conference, and some talks made him sleepy, so good job everyone.
Matched from the episode's transcript 👇
David Flanagan: Yeah, Brian Ketelsen and I are the creators and maintainers of CUE Blocks. We’re both huge fans of CUE. We think it’s just a great language for defining schema, applying constraints, and even doing some basic comprehensions and mathematics with them.
So it’s not a Turing-complete programming language, but they are starting to add more query APIs and other things to bring it in line with some of that.
So I really like Dagger… I have done an episode with Solomon on Rawkode Live, where we dug into Dagger and we did some deployments. I think it’s a really good tool, and I love seeing CUE used in this way. It’s very similar to TerraForm, in the regards of that you have to have something that understands the abstract form. The HCL, the Yaml, or even the CUE is just compiling down to Yaml at the end of the day anyway.
You’re still constrained in that you can’t do a lot of conditional logic. Loop logic does exist in CUE, and you can do some things like that… But then modifying things within the loop gets a bit difficult, because you’ve only got access to that array count. So it depends on your use case. But I think Dagger is great, and that they’re moving beyond, into like where Boundary is as well. I’m not sure if you’re familiar with HashiCorp’s Boundary…
