config-key layout
|
|
===================
|
|
|
|
*config-key* is a general-purpose key/value storage service offered by
|
|
the mons. Generally speaking, you can put whatever you want there.
|
|
Current in-tree users should be captured here with their key layout
|
|
schema.
|
|
|
|
OSD dm-crypt keys
|
|
=================
|
|
|
|
Key::
|
|
|
|
dm-crypt/osd/$OSD_UUID/luks = <json string>
|
|
|
|
The JSON payload has the form::
|
|
|
|
{ "dm-crypt": <secret> }
|
|
|
|
where the secret is a base64 encoded LUKS key.
|
|
|
|
Created by the 'osd new' command (see OSDMonitor.cc).
|
|
|
|
Consumed by ceph-volume, and similar tools. Normally access to the
|
|
dm-crypt/osd/$OSD_UUID prefix is allowed by a client.osd-lockbox.$OSD_UUID
|
|
cephx key, such that only the appropriate host can retrieve the LUKS key (which
|
|
in turn decrypts the actual raw key, also stored on the device itself).
|
|
|
|
|
|
ceph-mgr modules
|
|
================
|
|
|
|
The convention for keys is::
|
|
|
|
mgr/$MODULE/$option = $value
|
|
|
|
or::
|
|
|
|
mgr/$MODULE/$MGRID/$option = $value
|
|
|
|
For example,::
|
|
|
|
mgr/dashboard/server_port = 80
|
|
mgr/dashboard/foo/server_addr = 1.2.3.4
|
|
mgr/dashboard/bar/server_addr = 1.2.3.5
|
|
|
|
|
|
Configuration
|
|
=============
|
|
|
|
Configuration options for clients and daemons are also stored in config-key.
|
|
|
|
Keys take the form::
|
|
|
|
config/$option = $value
|
|
config/$type/$option = $value
|
|
config/$type.$id/$option = $value
|
|
config/$type.$id/$mask[/$mask2...]/$option = $value
|
|
|
|
Where
|
|
|
|
* `type` is a daemon type (`osd`, `mon`, `mds`, `mgr`, `client`)
|
|
* `id` is a daemon id (e.g., `0`, `foo`), such that `$type.$id` is something like `osd.123` or `mds.foo`)
|
|
* `mask` restricts who the option applies to, and can take two forms:
|
|
|
|
#. `$crush_type:$crush_value`. For example, `rack:foorack`
|
|
#. `class:$classname`, in reference to CRUSH device classes (e.g., `ssd`)
