kubernetes Cookbook
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.
