ceph mgr module enable dashboard

これで、8443 → 8080 ポートになる。

ceph config set mgr mgr/dashboard/ssl false

# ceph mgr services
{
    "dashboard": "http://ceph01:8080/",
}


===== 3.ユーザ設定 =====

user:admin, pass:adminxxxx, role:administratorで設定する場合

<code>
# ceph dashboard ac-user-create admin adminxxxx administrator
{"username": "admin", "lastUpdate": 1592953680, "name": null, "roles": ["administrator"], "password": "$2b$12$iOz46vkfT.zR62AmZXXXXXXXXXXXXXXXAlTOIx1Gz3az1CwqRlFe", "email": null}

これ以降はPrometheus と Grafanaで、Cephの状態を見たい時

cephのモジュールprometheus exporterをenableへ

ceph mgr module enable prometheus

ceph config set mgr mgr/prometheus/rbd_stats_pools glance,cinder,nova

  mkdir /app/grafana
  # cat docker-compose.yml
