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.
