A list of one or more policy names to associate with the server group. The list
must contain at least one policy name. The current valid policy names are ``anti-affinity``
, ``affinity``, ``soft-anti-affinity`` and ``soft-affinity``, the latter two were
added in microversion 2.15. Each policy name must be a non-empty string with
no leading or trailing spaces. Maximum length is 255 characters.
A list of exactly one policy name to associate with the server group. The
current valid policy names are:
- ``anti-affinity`` - servers in this group must be scheduled to
different hosts.
- ``affinity`` - servers in this group must be scheduled to the same host.
- ``soft-anti-affinity`` - servers in this group should be scheduled to
different hosts if possible, but if not possible then they should still
be scheduled instead of resulting in a build failure. This policy was
added in microversion 2.15.
- ``soft-affinity`` - servers in this group should be scheduled to the same
host if possible, but if not possible then they should still be scheduled
instead of resulting in a build failure. This policy was added in
microversion 2.15.
