Lighthouse Plugin

This repository implements a bundle of plugin to enhance the Kubernetes function. The provided features are listed below.

  • Docker runtime backend

1. Storage Options

Any annotations start with mixer.kubernetes.io/storage-opt- will be added to docker storage options.

apiVersion: v1
kind: Pod
metadata:
  ...
  annotations:
    mixer.kubernetes.io/storage-opt-size: "1G"

This above example means add size=1G to your container.

2. uts Options

Any annotations start with mixer.kubernetes.io/uts-mode will not use host namespace when host network is true.

apiVersion: v1
kind: Pod
metadata:
  ...
  annotations:
    mixer.kubernetes.io/uts-mode: ""

3. Pid limit

To prevent user's pids flood the host machine, we provide a method to set pid limit for user's container. If you want this feature, set mixer.kubernetes.io/pids-limit: <limit> to your pod's annotations.

apiVersion: v1
kind: Pod
metadata:
  ...
  annotations:
    mixer.kubernetes.io/pids-limit: "40"
spec:
  containers:
  - name: test

4. Offline Options

Offline pods with annotation mixer.kubernetes.io/app-class:greedy will be changed the cgroup path to "kubepods/offline".

apiVersion: v1
kind: Pod
metadata:
  ...
  annotations:
    mixer.kubernetes.io/app-class: "greedy"
