This role will install the following services:
  • designate-api
  • designate-central
  • designate-worker
  • designate-producer
  • designate-mdns
  • designate-sink

The DNS servers Designate will interface with can be defined in the designate_pools_yaml variable. This is eventually written to the Designate pools.yaml file.

## DNS Backend Configuration
#  Configuration for the DNS backend that Designate will talk to, Designate
#  supports lots of backends, bind9, powerdns, nsd, djb, dyn, akamai, etc.
#  DNS Backends are configured via a YAML file that Designate reads. The DNS
#  server need not be in the actual Designate container, but for development,
#  or for some internal addressing use cases, it may make sense.

# YAML to use for the Designate pools.yaml file. If this variable is defined,
# a pools.yaml file will be written to /etc/designate/pools.yaml with the
# provided YAML data.
# This is some example pools.yaml information that will work with a
# simple bind9 installation in the same container as Designate.
# designate_pools_yaml:
#   - name: "default"
