Terrakube with Google Cloud Identity Authentication

Requirements

To use this examples you will need the following:

  • Google Cloud Identity
  • Google Storage Bucket
  • MySQL

Before running the helm chart it is require to have a working ingress setup in your cluster (For example Ngnix Ingress but any other ingress should work)

YAML Example

Replace <<CHANGE_THIS>> with the real values

## Global Name
name: "terrakube"

## Terrakube Security
security:
  adminGroup: "<<CHANGE_THIS>>" # The value should be a gcp group (format: [email protected] example: [email protected])
  patSecret: "<<CHANGE_THIS>>"  # Sample Key 32 characters z6QHX!y@Nep2QDT!53vgH43^PjRXyC3X
  internalSecret: "<<CHANGE_THIS>>" # Sample Key 32 characters Kb^8cMerPNZV6hS!9!kcD*KuUPUBa^B3
  dexClientId: "google"
  dexClientScope: "email openid profile offline_access groups"
  gcpCredentials: |
    ## GCP JSON CREDENTIALS for service account with API Scope https://www.googleapis.com/auth/admin.directory.group.readonly
