Drone KubeConfig

Retrieve and create Drone secrets for Kubernetes service accounts

Quickly configure Drone to deploy across multiple Kubernetes clusters.

This script prepares repositories for Kubernetes deployments using the drone-helm plugin - which expects API_SERVER and KUBERNETES_TOKEN as secrets.

Pre-reqs

To keep the tool simple, it expects kubectl and drone binaries to exist in the $PATH and be fully configured.

Tested with Kubernetes 1.7.15 and Drone 0.8.0

Golang binary

NAME:
   drone-kubeconfig - create drone secrets for kubernetes service accounts

USAGE:
   drone-kubeconfig [global options] command [command options] [arguments...]

VERSION:
   0.1.1

COMMANDS:
     help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --repository value, -r value       repository name (e.g. octocat/hello-world)
   --context PREFIX, -c PREFIX        map PREFIX with equivalent `KUBE_CONTEXT` (e.g STAGING_1A=<kube-content-name>)
   --service-account value, -s value  Kubernetes service account for drone (default: "drone")
   --namespace value, -n value        Kubernetes namespace of service account (default: "kube-system")
   --timeout DURATION, -t DURATION    DURATION before commands are cancelled (default: 5s)
   --help, -h                         show help
   --version, -v                      print the version

Example usage:

bin/drone-kubeconfig -c PRODUCTION_1A=1a.prod.mycluster.com -c PRODUCTION_1B=1b.prod.mycluster.com octocat/hello-world

This will create the following secrets for octocat/hello-world:

  • PRODUCTION_1A_API_SERVER: The API server for the 1A kubernetes production cluster
  • PRODUCTION_1A_KUBERNETES_TOKEN: The token for the drone Service Account in the 1A kubernetes production cluster
  • PRODUCTION_1B_API_SERVER: The API server for the 1B kubernetes production cluster
  • PRODUCTION_1B_KUBERNETES_TOKEN: The token for the drone Service Account in the 1B kubernetes production cluster
