For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\n\nApigee hybrid supports [rolling\nupdates](https://kubernetes.io/docs/tutorials/kubernetes-basics/update/update-intro/). In Kubernetes, rolling updates allow Deployment updates to take place with zero\ndowntime by incrementally updating Pod instances with new ones.\n\nComponents that support rolling updates\n---------------------------------------\n\n\nIf you change property settings for any hybrid of the following components in your\noverrides file, you can use\nthe `revision` property to signal that you want to perform a rolling update\nto the affected pods.\n\n- `runtime`\n- `mart`\n- `udca`\n- `metrics`\n- `synchronizer`\n\nYou can also use `revision` when you change any\nof the following properties:\n\n- `nodeSelector.*`\n- `envs.*`\n- `imagePullSecrets.*`\n- `gcpProjectID`\n- `k8sClusterName`\n- `contractProvider`\n- `org`\n\nHow to perform a rolling update\n-------------------------------\n\n\nFor example, suppose you want to change the current `runtime` memory from 1Gi to\n5Gi:\n\n\nIn the current configuration, `revision` is set to `blue`: \n\n```\n...\nrevision: blue\n...\nruntime:\n replicaCountMin: 2\n replicaCountMax: 20\n resources:\n cpu: 1000m\n memory: 1Gi\n...\n```\n\n\nIn the new configuration, `revision` is changed to `green`, signaling\nthat you want to perform a rolling update when\nthe change is applied. The value you set `revision` to does not matter; you can\nuse any string you wish, as long as you change it from the previous value to something else. \n\n```\n...\nrevision: green\n...\nruntime:\n replicaCountMin: 2\n replicaCountMax: 20\n resources:\n cpu: 1000m\n memory: 5Gi\n...\n```\n\n\nWhen you apply the change, you can use the `-c` flag to only update a specific\npod. For example: \n\n```\napigeectl apply -f my-overrides.yaml -c runtime\n```\n\n\nOr, if you do not use `-c` all of the pods that have config changes will be updated."]]
