  • jsonnet

    Jsonnet - The data templating language

    > As an aside, the existence of the '{{ | indent 4 }}' function in helm should disqualify it from any serious use. Render, don't template.

    This. My first thought when I saw the indentation hack was "it can't be a serious, production-ready software".

    My take on this is as follows.

    If you have a simple use case, write your K8s manifests directly.

    If you have a complex use case, Helm is often more pain than its worth. Use alternatives, for example Jsonnet[0] with kubecfg[1]. Or emit manifests from your language of choice. Just don't use Helm.

  • cdk8s

    Define Kubernetes native apps and abstractions using object-oriented programming

  • k9s

    🐶 Kubernetes CLI To Manage Your Clusters In Style!

    For anyone managing a k8s cluster and are fatigued with memorizing and reciting kubectl commands should definitely take a look at k9s[0]. It provides a curses like interface for managing k8s which makes it really easy to operate and dive into issues when debugging. Move from grabbing logs for a pod to being at a terminal on the container and then back out to looking at or editing the yaml for the resource definition in only a few key presses.

        helm diff upgrade   --namespace 

  • cert-manager

    "kubectl apply -f https://github.com/cert-manager/cert-manager/releases/downlo..."

    Taken straight from their docs.

  • yq

    yq is a portable command-line YAML, JSON, XML, CSV, TOML and properties processor

    I actually used to sed configurations, now I use yq[0] whenever I need to programatically edit YAML/JSON. It has much less side effects.

    But for Kubernetes manifests specifically, the right tool for the job is Kustomize[1]. It ships with kubectl and I'm a big believer in using default tools when possible.

    > Like you're installing new version, do you go over manifests and edit those by hand over and over every update?

    I check the patch notes, diff the configuration files to see if anything new popped up, do the required changes if necessary, jump the version number and deploy.

    It sounds laborious but it's really not that much work most of the time, and more importantly it forces you to have a good sense for what and how everything works. Plus it allows you to have a completely transparent, readable environment. Both are important for keeping things running in a production environment. Otherwise you might find yourself debugging incomprehensible systems you've never paid attention to in the middle of the night with 2 hours left before traffic starts coming in.
