Summary

In summary:

• Kubernetes Manifests are the basic way of deploying things to kubernetes
  • raw YAML files: no portability, no customisation, no code reuse
• Use Helm to package manifests into installable units
  • powerful templating (Go Templates), rich context information and parameters (values.yaml)
  • possible to publish Helm charts to registries (sharing)
  • umbrella charts to group multiple charts under a parent one (sub-charts)
• Use helmfile to group and manage multiple helm charts as one
  • you still have separate helm releases (vs umbrella chart)
  • declarative YAML with many features (envs, templates)
  • powerful CLI with tons of options
• Use Argo CD to add GitOps and automation to the mix
  • automatically syncs the state defined in a git repo with one or more clusters
  • supports raw manifests, kustomize, helm, jsonnet, … (+ helmfile through a plugin)
  • and much more! multi-cluster support, ApplicationSets, etc.
