Our AKS cluster was configured to auto-renew Let's Encrypt certificates through Ingress Cert-Manager annotation and this worked perfectly until we upgraded to AKS 1.20.7. This then stopped working ...

I have prayed for this for so long, it's hard to believe Roe was finally overturned. This should spur on our efforts to support and care for women and families tempted to see abortion as their best or only option, to point them to the truth.

Has anything changed with the way that JSON Patch works in #Kubernetes recently? Seeing some failed interactions due to missing the /data/ in the path, and requiring it to be a list of operations. Not quite sure why my code has ever worked tbh 😅

This is a really great idea - API gateways / ingress tooling utilising OpenAPI is much better than requiring duplication, and ensures that teams are building with API documentation first, but would be a barrier for those who need to backfill docs

First, make sure you understand what Kubernetes is, and how to leverage it. Second, challenge how you got to step two. If it still makes sense, start with a managed offering, and avoid getting sidetracked cosplaying SRE instead of building your business. cloud.google.com/kubernetes-eng…

After migrating my personal APIs to #Kubernetes, I've got a tonne of blog posts to write up 🙌🏼

Thu, 20 May 2021 22:21 by Jamie Tanna . #kubernetes.

#Kubernetes peeps - is there a way to mount a Secrets volume as read-write and allow an application to write to it? I'm migrating code that expects a filesystem to persist secret changes to and am not sure if I'm trying to avoid rewriting too much?

Wed, 12 May 2021 01:44 by Jamie Tanna . #kubernetes.

Is anyone using #gitlab's Auto DevOps with a Maven/Gradle multimodule project? Thinking about maybe giving it a go, with deployment to GKE for ease of management of my services, but wanna find out if its suitable first, and how to pass secrets that would be in an application.properties on the host. Or I guess, do I need to rewire the app instead?

oh it's simple. you write the app, then you write the dockerfile. then you write the helm chart. then you write the deployment to describe the helm chart which describes the deployment for the containerized app. In this simple tutorial, we will launch a hello world app.. 1/496
