Deployment

Quick Start

R.deployment :backend do
  # Specify number of replicas
  replicas 2

  # Specify labels
  match_labels feature: :main, component: :backend

  container do
    # Define main container
  end
end

Deployment is one of the Pod Template Owners, so all methods, like pod_template and container are available.

replicas

Shortcut to spec.replicas, used to specify desired number of Pod replicas:

R.deployment :backend do
  replicas 2
end

match_labels

Used to tell Deployment how to find its Pods. Labels are specified in the Pod template and the same labels (or match expressions) are specified in the Deployment selector (.spec.selector):

R.deployment :backend do
  match_labels feature: :main, component: :backend
end

The code above will generate the following YAML:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: backend
spec:
  selector:
    matchLabels:
      feature: main
      component: backend
  template:
    metadata:
      feature: main
      component: backend
...
