  "content": "# Sync Phases and Waves\n\nSync phases and hooks define when resources are applied such as before or after the main sync operation. This makes it possible to define jobs, or any other resource to run or be applied in any specific order.\n\nArgo CD has the following hook types:\n\n| Hook | Description |\n| --- | --- |\n| `PreSync` | Executes prior to the application of the manifests. |\n| `Sync` | Executes after all `PreSync` hooks completed and were successful, at the same time as the application of the manifests. |\n| `Skip` | Indicates to Argo CD to skip the application of the manifest. |\n| `PostSync` | Executes after all `Sync` hooks completed and were successful, a successful application, and all resources in a `Healthy` state. |\n| `SyncFail` | Executes when the sync operation fails. |\n| `PreDelete` | Executes before Application resources are deleted. Only runs when the entire Application is being deleted, not during normal sync operations (even with pruning enabled. ) |\n| `PostDelete` | Executes after all Application resources are deleted. *Available starting in v2.10.* |\n\nAdding the argocd.argoproj.io/hook annotation to a resource will assign it to a specific phase. During a Sync operation, Argo CD will apply the resource during the appropriate phase of the deployment. Hooks can be any type of Kubernetes resource kind, but tend to be Pod, Job or Argo Workflows. Multiple hooks can be specified as a comma separated list.\n\n## How phases work?\n\nArgo CD will respect resources assigned to different phases, during a sync operation Argo CD will do the following:\n\n1. Apply all the resources marked as PreSync hooks. If any of them fails the whole sync process will stop and will be marked as failed\n2. Apply all the resources marked as Sync hooks. If any of them fails the whole sync process will be marked as failed. Hooks marked with SyncFail will also run\n3. Apply all the resources marked as PostSync hooks. If any of them fails the whole sync process will be marked as failed.\n\nHoo… [9,823 more characters]",
