What if your Pods need to trust self-signed certificates?
I've built a small MutatingAdmissionWebhook controller [0] that handles this, via a pod annotation whose value is a secret with `ca.crt` inside, and it uses the (mostly) de facto standard openssl variables to configure the libraries, so that it works across pretty much everything I've tried it with off the shelf.
I build a bundle (though I may just move to trust-manager [1]) and replicate it into all namespaces with kubernetes-replicator [2], and then I can annotate any pod with

To anyone hosting in Kubernetes: Do you put all of your apps in one namespace (e.g., default), or one app per namespace?
Whichever way you go, I’ve successfully used this to replicate secrets: https://github.com/mittwald/kubernetes-replicator

How do you keep timezone data up-to-date?
So far I came across k8tz, which could be a solution.
- k8tz: Kubernetes admission controller and a CLI tool to inject timezones into Pods and CronJobs

Mounting a file from existing container to another in same pod
i recently saw some interesting github project that use emptyDir volume that first mounts to an initContainer with script that copy files from the container to the emptyDir and after that you mount this emptyDir to your actual container. you can even mount specific files using subPath. the initContainer image is written in golang and it is conpiled in a way that it can run in empty container (FROM scratch). the binary is very small so there is no big overhead on the image size...
