Ceph » Orchestrator

Current situation

Right now, we have already three different type of things that ceph orch apply supports:

• Standard services: service_type: mon|mgr|rgw...
• Host specs: service_type: host
• Generic Deployments: service_type: container

Idea

The idea is to distinguish them better for the user. Make it clear that a host spec is not a service.

kind: host
hostname: foobar
addr: 127.0.0.1

is better than

service_type: host
hostname: foobar
addr: 127.0.0.1

Thus, I propose to add another layer called kind: host|service|deployment on top of service_type.

Like so:

kind: host
hostname: myhost1
labels:
- rgw
---
kind: service
service_type: rgw
service_id: foobar
spec:
  realm: myrealm
  zone: myzone
---
kind: rgw_realm
name: realm-a
pull_endpoint: http://10.2.105.133:80
---
kind: rgw_zone
name: zone-a
---
kind: deployment
service_name: prometheus-webhook-snmp
placement:
    ADD_PLACEMENT_HERE
image: hello:latest
ports:
- 999: 999
envs:
- args="--debug --snmp-host=ADD_HOST_GATEWAY_HERE --metrics" 

ceph orch apply -i cluster.yaml

or

cephadm bootstrap --apply-spec cluster.yaml
