Introspect Data Helm Chart Repository

Please note - these are meant to be used as examples for specific usecases. In general, we don't advise using these charts as-is for most environments, but figured they were worth sharing given the amount of effort we put into it!

Prerequisites

• kubectl installed
• helm installed (requires kubectl)
• Your local kubeconfig set up to talk to your K8s cluster
• Our private helm repo needs to be installed (hosted on in this repo!)
  • We're following this process... mostly
  • Add the helm chart to your local repos list:

helm repo add id-public  "https://raw.githubusercontent.com/introspectdata/helm-public/master/"

CI Workflow

This project has a bit of an 'odd' CI workflow through CircleCI:

• Only commits to master trigger builds
• Within that build, each individual chart needs to be specified in the build configuration
• If you're adding a new chart--make sure you update the build!
• This specific build profile has it's SSH deploy key set to read/write - so once it lints, packages and re-indexes the helm repo, it pushes to github again
  • VERY IMPORTANT - the comment of the commit from CircleCI has a [skip ci] directive that makes it so that it doesn't loop infinitely.
