Ceph default configuration options

Ceph Controller provides the capability to specify configuration options for the Ceph cluster through the spec.cephClusterSpec.rookConfig key-value parameter of the KaaSCephCluster resource as if they were set in a usual ceph.conf file. For details, see Ceph advanced configuration.

However, if rookConfig is empty, Ceph Controller still specifies the following default configuration options for each Ceph cluster:

  • Required network parameters that you can change through the spec.cephClusterSpec.network section:

    cluster network = <spec.cephClusterSpec.network.clusterNet>
public network = <spec.cephClusterSpec.network.publicNet>

  • General default configuration options that you can override using the rookConfig parameter:

    mon target pg per osd = 200
mon max pg per osd = 600

# Workaround configuration option to avoid the
# https://github.com/rook/rook/issues/7573 issue
# when updating to Rook 1.6.x versions:
rgw_data_log_backing = omap

If rookConfig is empty but the spec.cephClsuterSpec.objectStore.rgw section is defined, Ceph Controller specifies the following OpenStack-related default configuration options for each Ceph cluster:

  • Ceph Object Gateway options, which you can override using the rookConfig parameter:

    rgw swift account in url = true
rgw keystone accepted roles = '_member_, Member, member, swiftoperator'
rgw keystone accepted admin roles = admin
rgw keystone implicit tenants = true
rgw swift versioning enabled = true
rgw enforce swift acls = true
rgw_max_attr_name_len = 64
rgw_max_attrs_num_in_req = 32
rgw_max_attr_size = 1024
rgw_bucket_quota_ttl = 0
rgw_user_quota_bucket_sync_interval = 0
rgw_user_quota_sync_interval = 0
rgw s3 auth use keystone = true

  • Additional parameters for the Keystone integration:

    Warning

    All values with the keystone prefix are programmatically specified for each MOSK deployment. Do not modify these parameters manually.

    rgw keystone api version = 3
rgw keystone url = <keystoneAuthURL>
rgw keystone admin user = <keystoneUser>
rgw keystone admin password = <keystonePassword>
rgw keystone admin domain = <keystoneProjectDomain>
rgw keystone admin project = <keystoneProjectName>
