Docker Compose files to distribute and delete gMSA Cred Spec files across a Swarm Cluster

1. Distribute Credential Spec File

# Distribute a Credential Spec file to all Windows Server cluster nodes
# gmsa.json by default, else set $env:CREDSPEC with filename
version: '3.3'
configs:
  credspec:
    file: ${ProgramData}/Docker/CredentialSpecs/${CREDSPEC:-gmsa.json}
services:
  copy:
    command: cmd /c copy credspec C:\\out\\${CREDSPEC:-gmsa.json}
    configs:
      - credspec
    deploy:
      mode: global
      restart_policy:
        condition: none
      placement:
        constraints:
        - node.platform.os == windows
    image: microsoft/nanoserver
    volumes:
      - source: ${ProgramData}/Docker/CredentialSpecs
        target: C:\out
        type: bind

2. Delete Credential Spec File

# Delete a Credential Spec file from all Windows Server cluster nodes
# gmsa.json by default, else set $env:CREDSPEC with filename
version: '3.3'
services:
  copy:
    command: cmd /c del C:\\out\\${CREDSPEC:-gmsa.json}
    deploy:
      mode: global
      restart_policy:
        condition: none
      placement:
        constraints:
        - node.platform.os == windows
    image: microsoft/nanoserver
    volumes:
      - source: ${ProgramData}/Docker/CredentialSpecs
        target: C:\out
        type: bind
