options:
  source:
    type: string
    default: distro
    description: |
      Repository from which to install. May be one of the following:
      distro (default), ppa:somecustom/ppa, a deb url sources entry,
      or a supported Ubuntu Cloud Archive e.g.
      .
      cloud:<series>-<openstack-release>
      cloud:<series>-<openstack-release>/updates
      cloud:<series>-<openstack-release>/staging
      cloud:<series>-<openstack-release>/proposed
      .
      See https://wiki.ubuntu.com/OpenStack/CloudArchive for info on which
      cloud archives are available and supported.
  base-port:
    type: int
    default: 3306
    description: |
        Base port number for RW interface. RO, xRW and xRO will
        increment from base_port.
  ttl:
    type: float
    default: .5
    description: |
        Time to live (in seconds) of information in the metadata cache.
        Accepts either an integer or a floating point value. The granularity is
        limited to milliseconds, where 0.001 equates to one millisecond.
        Precision is truncated to the supported range; for example ttl=0.0119
        is treated as 11 milliseconds. The value 0 means that the metadata
        cache module queries the metadata continuously in a tight loop.
  auth_cache_refresh_interval:
    type: int
    default: 2
    description: |
        Time (in seconds) between the auth-cache refresh attempts. Defaults to
        2. The value must be smaller than auth_cache_ttl and ttl else Router
        won't start.
  auth_cache_ttl:
    type: int
    default: -1
    description: |
        Time (in seconds) until the cache becomes invalid if not refreshed.
        Defaults to -1 (infinite). The value must be larger than
        auth_cache_refresh_interval else Router won't start.
