    type: json
  ServiceNetMap:
    default: {}
    description: Mapping of service_name -> network name. Typically set

    type: json
    description: >
      SSH key for migration.
      Expects a dictionary with keys 'public_key' and 'private_key'.
      Values should be identical to SSH public/private key files.

    type: number

conditions:

  # During Ocata->Pike upgrade initially configure the ssh service on port 22
  # to proxy migration commands to the containerized sshd on port 2022.
  # When the upgrade converges we can switch migrations over to port 2022.
