DeepSea orchestrator integration¶
DeepSea (https://github.com/SUSE/DeepSea) is a collection of Salt state files, runners and modules for deploying and managing Ceph.
The deepsea module provides integration between Ceph’s orchestrator
framework (used by modules such as dashboard to control cluster services)
and DeepSea.
Orchestrator modules only provide services to other modules, which in turn provide user interfaces. To try out the deepsea module, you might like to use the Orchestrator CLI module.
Requirements¶
A salt-master node with DeepSea 0.9.9 or later installed, and the salt-api service running.
Ideally, several salt-minion nodes against which at least DeepSea’s stages 0 through 2 have been run (this is the minimum required for the orchestrator’s inventory and status functions to return interesting information).
Configuration¶
Four configuration keys must be set in order for the module to talk to salt-api:
salt_api_url
salt_api_username
salt_api_password
salt_api_eauth (default is “sharedsecret”)
These all need to match the salt-api configuration on the salt master (see eauth.conf, salt-api.conf and sharedsecret.conf in /etc/salt/master.d/ on the salt-master node).
Configuration keys¶
Configuration keys can be set on any machine with the proper cephx credentials, these are usually Monitors where the client.admin key is present.
ceph deepsea config-set <key> <value>
For example:
ceph deepsea config-set salt_api_url http://admin.example.com:8000/
ceph deepsea config-set salt_api_username admin
ceph deepsea config-set salt_api_password 12345
The current configuration of the module can also be shown:
ceph deepsea config-show
Debugging¶
Should you want to debug the deepsea module, increase the logging level for ceph-mgr and check the logs.
[mgr]
debug mgr = 20
With the log level set to 20, the module will print out all the data received from the salt event bus. All log messages will be prefixed with mgr[deepsea] for easy filtering.
