Getting Started

The Kubernetes plugin can deploy a Docker image of an application to Kubernetes, expose the Deployment with a Kubernetes Service, and source configuration from a Kubernetes Secret or ConfigMap. It also launches on-demand runners to do operations remotely.

Components

  1. Platform
  2. ReleaseManager
  3. ConfigSourcer
  4. TaskLauncher
  1. Docker

Resources

Platform
  1. Kubernetes Deployment
  2. Kubernetes Autoscaler

Functions

func Clientset added in v0.6.0 

func Clientset(kubeconfig, context string) (*kubernetes.Clientset, string, *rest.Config, error)
