Deploying iSCSI
===============
To deploy an iSCSI gateway, create a yaml file containing a
service specification for iscsi:
.. code-block:: yaml
service_type: iscsi
service_id: iscsi
placement:
hosts:
- host1
- host2
spec:
pool: mypool # RADOS pool where ceph-iscsi config data is stored.
trusted_ip_list: "IP_ADDRESS_1,IP_ADDRESS_2"
api_port: ... # optional
api_user: ... # optional
api_password: ... # optional
api_secure: true/false # optional
ssl_cert: | # optional
...
ssl_key: | # optional
...
For example:
.. code-block:: yaml
service_type: iscsi
service_id: iscsi
placement:
hosts:
- [...]
spec:
pool: iscsi_pool
trusted_ip_list: "IP_ADDRESS_1,IP_ADDRESS_2,IP_ADDRESS_3,..."
api_user: API_USERNAME
api_password: API_PASSWORD
ssl_cert: |
