k8s

When working with multiple Kubernetes clusters and namespaces switching context can be a chore.

For this I enjoy using kubectx and kubens.

They can be installed using kubectl krew.

kubectl krew install ctx
kubectl krew install ns

This is a simple script that takes multiple kube config files and deeply merges them into one.

Debugging container workloads can be a challenge sometimes, especially when running them in k8s, behind a reverse proxy or in other, possibly complex, traffic flow scenarios.

How to add things to a list using kustomize. This is useful for example when you need to patch additional environment variables into a pod.

Since early 2019 the sprig library used by helm provides a concat function that does exactly this.

I have run and am still running loads of Kubernetes clusters, mostly on-premise.
