Scale a Deployment Using Replicas#

You can update a deployment to change the number of replicas as shown below. You may prefer to use an auto-scaler as described in Scale a Deployment Using a Horizontal Pod Autoscaler.

Example Customization#

  1. Create an overlay structure as described in Customize ESS.

  2. Add the customization overlay:

    #kustomization.yaml

...

patches:
  - target:
      kind: Deployment
      name: ess-signup-static
    patch: |-
      -  op: add
         path: /spec/replicas
         value: 3

    By adding more Signup page pods, the customization helps with resiliency.
