For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\nYou can scale most services running in Kubernetes from the\ncommand line or in a configuration override. You can set scaling\nparameters for Apigee hybrid runtime services in the\n[`overrides.yaml` file](/apigee/docs/hybrid/v1.6/customize-services).\n\nAdvanced configurations\n-----------------------\n\n\nIn some scenarios, you may need to use advanced scaling options. Example scenarios include:\n\n- Setting different scaling options for each environment. For example, where env1 has a `minReplica` of 5 and env2 has a `minReplica` of 2.\n- Setting different scaling options for each component within an environment. For example, where the `udca` component has a `maxReplica` of 5 and the `synchronizer` component has a `maxReplica` of 2.\n\n\nThe following example shows how to use the `kubernetes patch` command to change\nthe `maxReplicas` property for the `runtime` component:\n\n\n1. Create environment variables to use with the command: \n\n ```gdscript\n export ENV=my-environment-name\n export NAMESPACE=apigee #the namespace where apigee is deployed\n export COMPONENT=runtime #can be udca or synchronizer\n export MAX_REPLICAS=2\n export MIN_REPLICAS=1\n ```\n2. Apply the patch. Note that this example assumes that `kubectl` is in your `PATH`: \n\n ```carbon\n kubectl patch apigeeenvironment -n $NAMESPACE \\\n $(kubectl get apigeeenvironments -n $NAMESPACE -o jsonpath='{.items[?(@.spec.name == \"'$ENV'\" )]..metadata.name}') \\\n --patch \"$(echo -e \"spec:\\n components:\\n $COMPONENT:\\n autoScaler:\\n maxReplicas: $MAX_REPLICAS\\n minReplicas: $MIN_REPLICAS\")\" \\\n --type merge\n ```\n3. Verify the change: \n\n ```text\n kubectl get hpa -n $NAMESPACE\n ```"]]
