Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly MCC). This means everything you need is in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Ceph default configuration options¶

Warning

This procedure is valid for MOSK clusters that use the MiraCeph custom resource (CR), which is available since MOSK 25.2 to replace the deprecated KaaSCephCluster. For the equivalent procedure with the KaaSCephCluster CR, refer to the following section:

Ceph default configuration options

Ceph Controller provides the capability to specify configuration options for the Ceph cluster through the rookConfig key-value section of the MiraCeph CR 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 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 objectStore.rgw section is defined, Ceph Controller specifies the following OpenStack-related default configuration options for each Ceph cluster:

Ceph Object Gateway options that 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>
