Ceph » Orchestrator

1. Deploy cluster using cephadm
2. Deploy iscsi services using iscsi.yml file

[ceph: root@magna007 ~]# cat iscsi.yml 
service_type: iscsi
service_id: iscsi
placement:
  hosts:
  - host1
  - host2
spec:
  pool: iscsi_pool
  trusted_ip_list: "10.8.128.108,10.8.128.113" 
  api_user: admin
  api_password: admin

3. Login to container using "podman exec -it 12e38d148b25 /bin/sh" then do gwcli
4. Create target and gateways

[root@host1 ~]# podman exec -it 99b46c7235da sh

sh-4.4# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.8.128.108 host1 host1
10.8.128.113 host2 host2
127.0.1.1 host1 host1 ceph-3ce40d5c-dd5a-11eb-8a7a-002590fc2538-iscsi.iscsi.host1.kkxugr-tcmu
