Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

kubernetes Cookbook

Build Status Cookbook Version

Resources for deploying various Kubernetes entities, these resources are designed to be ran on the kubernetes master but can be ran anywhere that has access to a kubernetes api by changing the ['kubernetes']['master']['ip'] attribute. These resources utilize the kubeclient ruby gem and run against the v1beta1 api.

Currently broken resources: (waiting on support for v1 api through kubeclient gem)

  • Kubernetes Pod (kube_pod)
  • Kubernetes Replication Controller (kube_replication_controller)
  • Kubernetes Service (kube_service)

Requirements

Platforms

  • All platforms where kubeclient gem can be installed

Chef

  • Chef 14+

Cookbooks

  • build-essential

Attributes

  • ['kubernetes']['master']['ip'] - the address used when contacting the kubernetes api
  • ['kubernetes']['master']['port'] - the port that will be used when contacting the kubernetes api
  • ['kubernetes']['client_version'] - the version of the kubeclient gem to install

Resources

Kubernetes Pod (kube_pod)

Manage a standalone Kubernetes pod, there is no redundancy in a pod and is simply used to specify a group of containers to be jointly deployed on a host.

Actions

  • create - default. ensures the pod is created
  • destroy - ensures the pod does not exist

Attribute Parameters

  • id - name attribute. The identifier used when managing the pod
  • containers - required a hash of container information that will be used when creating the pod
  • volumes - a hash of volume information used when specifying storage for containers
  • labels - specify the labels that will be added to the pod

Examples

kube_pod "my-pod" do
  containers({
    name: 'pod-member',
    image: 'my/image'
  })
  labels "aww=yiss"
  action [:destroy,:create]
end

Kubernetes Replication Controller (kube_replication_controller)

Replication controllers are used to maintain a consistent amount of a pod at any given time using selector labels

Actions

  • create - default. ensures the replication controller is created
  • destroy - ensures the replication controller does not exist

Attribute Parameters

  • id - name attribute. The identifier used when managing the replication controller
  • containers - required a hash of container information that will be used when the replication controller needs to generate new pods
  • volumes - a hash of volume information used in generating new pods
  • selector - how the replication controller will ensure that enough replicas exist
  • pod_labels - specify the labels added to the individual pods that are spawned off
  • labels - specify the labels that will be added to the replication controller

Examples

kube_replication_controller "master-controller" do
  containers({
    name: 'redis-master',
    image: 'dockerfile/redis'
  })
  replicas 2
  selector 'role' => 'master','app' => 'redis'
  labels ['aww=yiss','motha-freakin=breadcrumbs']
  action [:destroy,:create]
end

Kubernetes Service (kube_service)

Deploy a Kubernetes service, which can be used as a basic container load balancer that routes traffic based on selector labels

Actions

  • create - default. ensure the service exists
  • destroy - ensure the service does not exist

Attribute Parameters

  • id - name attribute. The identifier used when managing the service
  • port - required the port that the service will listen on for traffic
  • container_port - what port the service will route to on the selected containers defaults to the port that the service is listening on
  • selector - labels that the service will use when choosing containers to route traffic to
  • labels - labels that will be added to the service

Examples

kube_service "backend-service" do
  port 8005
  selector 'role' => 'backend'
end

Containers and Volumes

The syntax used when specifying containers and volumes is specific to the kubernetes api, for examples on what these can/should look like please see the kubernetes documentation/examples.

Labels

Theres a bit of magic in the helper library that allows you to specify labels as either a hash 'this' => 'that', 'app' => 'redis', an array of labels ['this=that','app=redis'], or a comma delimited string 'this=that,app=redis'. All three will be treated as the same thing when writing your resources.
