The GMSA credential spec does not contain secret or sensitive data. It is information that a container runtime can use to describe the desired GMSA of a container to Windows. GMSA credential specs can be generated in YAML format with a utility PowerShell script.\n\nFollowing are the steps for generating a GMSA credential spec YAML manually in JSON format and then converting it\n\nImport the CredentialSpec module: ipmo CredentialSpec.psm1\n\nCreate a credential spec in JSON format using New-CredentialSpec. To create a GMSA credential spec named WebApp1, invoke New-CredentialSpec -Name WebApp1 -AccountName WebApp1 -Domain $(Get-ADDomain -Current LocalComputer)\n\nUse Get-CredentialSpec to show the path of the JSON file.\n\nConvert the credspec file from JSON to YAML format and apply the necessary header fields apiVersion, kind, metadata and credspec to make it a GMSACredentialSpec custom resource that can be configured in Kubernetes.\n\nThe following YAML configuration describes a GMSA credential spec named gmsa-WebApp1\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: windows.k8s.io/v1\nkind: GMSACredentialSpec\nmetadata:\n  name: gmsa-WebApp1  # This is an arbitrary name but it will be used as a reference\ncredspec:\n  ActiveDirectoryConfig:\n    GroupManagedServiceAccounts:\n    - Name: WebApp1   # Username of the GMSA account\n      Scope: CONTOSO  # NETBIOS Domain Name\n    - Name: WebApp1   # Username of the GMSA account\n      Scope: contoso.com # DNS Domain Name\n  CmsPlugins:\n  - ActiveDirectory\n  DomainJoinConfig:\n    DnsName: contoso.com  # DNS Domain Name\n    DnsTreeName: contoso.com # DNS Domain Name Root\n    Guid: 244818ae-87ac-4fcd-92ec-e79e5252348a  # GUID of the Domain\n    MachineAccountName: WebApp1 # Username of the GMSA account\n    NetBiosName: CONTOSO  # NETBIOS Domain Name\n    Sid: S-1-5-21-2126449477-2524075714-3094792973 # SID of the Domain\n```\n\nThe above credential spec resource may be saved as gmsa-Webapp1-credspec.yaml and applied to the cluster using: kubectl apply -f gmsa-Webapp1-credspec.yml\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
