# NOTE: This is included from two paths to setup the bridge/bastion
# host in different circumstances:
#
# 1) Gate tests -- here Zuul is running this on the executor against
#    ephemeral nodes.  It uses the "bastion" group as defined in the
#    system-config-run jobs.
#
# 2) Production -- here we actually run against the real bastion host.
#    The host is dynamically added in opendev/base-jobs before this
#    runs, and put into a group called "bastion".
#
# In both cases, the "bastion" group has one entry, which is the
# bastion host to run against.

    # ephemeral nodes have been made to trust this by the multinode
    # setup.
    #
    # NOTE(ianw) : Another option here is to keep the root key as a
    # secret directly in Zuul, which could be written out directly
    # here.  Maybe one day we will do something like this.
