This configures all containers in the Pod spec to use the specified GMSA. A sample Pod spec with the annotation populated to refer to gmsa-WebApp1\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: apps/v1\nkind: Deployment\nmetadata:\n  labels:\n    run: with-creds\n  name: with-creds\n  namespace: default\nspec:\n  replicas: 1\n  selector:\n    matchLabels:\n      run: with-creds\n  template:\n    metadata:\n      labels:\n        run: with-creds\n    spec:\n      securityContext:\n        windowsOptions:\n          gmsaCredentialSpecName: gmsa-webapp1\n      containers:\n      - image: mcr.microsoft.com/windows/servercore/iis:windowsservercore-ltsc2019\n        imagePullPolicy: Always\n        name: iis\n      nodeSelector:\n        kubernetes.io/os: windows\n```\n\nIndividual containers in a Pod spec can also specify the desired GMSA credspec using a per-container securityContext.windowsOptions.gmsaCredentialSpecName field. For example\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: apps/v1\nkind: Deployment\nmetadata:\n  labels:\n    run: with-creds\n  name: with-creds\n  namespace: default\nspec:\n  replicas: 1\n  selector:\n    matchLabels:\n      run: with-creds\n  template:\n    metadata:\n      labels:\n        run: with-creds\n    spec:\n      containers:\n      - image: mcr.microsoft.com/windows/servercore/iis:windowsservercore-ltsc2019\n        imagePullPolicy: Always\n        name: iis\n        securityContext:\n          windowsOptions:\n            gmsaCredentialSpecName: gmsa-Webapp1\n      nodeSelector:\n        kubernetes.io/os: windows\n```\n\nAs Pod specs with GMSA fields populated (as described above) are applied in a cluster, the following sequence of events take place\n\nThe mutating webhook resolves and expands all references to GMSA credential spec resources to the contents of the GMSA credential spec.\n\nThe validating webhook ensures the service account associated with the Pod is authorized for the use verb on the specified GMSA credential spec. …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
