This generally includes everything +needed to configure the service excluding the local bind ports which +are still managed in the per-node role templates directly (controller.yaml, +compute.yaml, etc.). All other (global) service settings go into +the puppet/service templates. + +Input Parameters +---------------- + +Each service may define its own input parameters and defaults. +Operators will use the parameter_defaults section of any Heat +environment to set per service parameters. + +Config Settings +--------------- + +Each service may define a config_settings output variable which returns +Hiera settings to be configured. + +Steps +----- + +Each service may define an output variable which returns a puppet manifest +snippet that will run at each of the following steps. Earlier manifests +are re-asserted when applying latter ones. + + * config_settings: Custom hiera settings for this service. + + * step_config: A puppet manifest that is used to step through the deployment + sequence. Each sequence is given a "step" (via hiera('step') that provides + information for when puppet classes should activate themselves. + + Steps correlate to the following: + + 1) Load Balancer configuration + + 2) Core Services (Database/Rabbit/NTP/etc.) + + 3) Early Openstack Service setup (Ringbuilder, etc.) + + 4) General OpenStack Services + + 5) Service activation (Pacemaker) + + 6) Fencing (Pacemaker) diff --git a/puppet/services/services.yaml b/puppet/services/services.yaml new file mode 100644 index 00000000..f9681634 --- /dev/null +++ b/puppet/services/services.yaml @@ -0,0 +1,40 @@ +heat_template_version: 2016-04-08 + +description: > + Utility stack to convert an array of services into a set of combined + role configs. + +parameters: + Services: + default: [] + description: | + List nested stack service templates. + type: comma_delimited_list + EndpointMap: + default: {} + description: Mapping of service endpoint -> protocol.
