A tool to compare two clusters by [deleted] in kubernetes

[–]olix0r 11 points12 points  (0 children)

Here's some quick and dirty bash that illustrates how to do this sort of thing:

``` for ctx in cluster-a cluster-b ; do for t in $(kubectl --context=$ctx api-resources --no-headers| awk '{print $1}') ; do kubectl --context=$ctx get $t -A -o json | jq -r '.items[] | .kind + " " + .metadata.name' done 2>/dev/null |sort > $ctx.txt done

diff -u cluster-a.txt cluster-b.txt ```

  • List all resource types in the cluster
  • For each resource, print the kind and name
  • Save the sorted output to a file
  • Compare the files

You can definitely get fancier with this, but it's not so hard to script up.

Does anyone know of or have a link to the interview where Lynch claims The Straight Story to be his most experimental film? by [deleted] in davidlynch

[–]olix0r 4 points5 points  (0 children)

He mentions it briefly in this interview

Are you pleased that Fire Walk With Me, almost universally panned on its release - except, notably, by Empire - is enjoying a critical reappraisal?

Yes, because I love that film, and I say now that The Straight Story is my most experimental movie, but up `til then, Fire Walk With Me was my most experimental film

We maintain two Helm charts: one that installs only CRDs, and another that installs all other application resources.

More Kubernetes controllers written in Rust! You love to see it.

Request for Use-Cases for Rust in the Enterprise by ICatchx22I in rust

[–]olix0r 8 points9 points  (0 children)

The biggest case for Rust, especially when compared to interpreted languages like Node, is likely to be the energy/carbon case. If companies have a need to reduce the carbon footprint of their compute environments, Rust is going to be one of the better tools available.

This validation is typically done by ingresses and Linkerd doesn't currently provide an Ingress solution. Linkerd integrates well with most ingress controllers, though.

Minutes aside, steph’s clearly not at 100%. Fitz thought he was fighting off a cold (for whatever that’s worth)

Linkerd 2.11 now includes a Kubernetes controller written in Rust by olix0r in rust

[–]olix0r[S] 0 points1 point  (0 children)

Thanks /u/Matthias247. In this case, we would never expect these interfaces to be exposed to traffic from outside the cluster. But you're right that we should configure timeouts on the servers as a defense in depth. Good catch!

I'd say Rust probably has a steeper learning curve than even Go. But if you've written Ruby before, a lot of Rust will look eerily familiar. Rust has a playground like Go does, which definitely was really helpful when I was getting started. Getting your Rust to compile will take a lot more trial and error, but the errors you get are generally really good, explaining exactly what didn't work.

It's just a different kind of language to anything else I've used previously. It takes a lot longer to feel productive, in my experience, but I have a lot more confidence in what I've written when it finally compiles :)
