Learn about configurations >

• auth-supported | string

  Default: cephx

  Which authentication flavour to use. . Valid options are "cephx" and "none". If "none" is specified, keys will still be created and deployed so that it can be enabled later.

• ceph-cluster-network | string

  The IP address and netmask of the cluster (back-side) network (e.g., 192.168.0.0/24) . If multiple networks are to be used, a space-delimited list of a.b.c.d/x can be provided.

• ceph-public-network | string

  The IP address and netmask of the public (front-side) network (e.g., 192.168.0.0/24) . If multiple networks are to be used, a space-delimited list of a.b.c.d/x can be provided.

• customize-failure-domain | boolean

  Setting this to true will tell Ceph to replicate across Juju's Availability Zone instead of specifically by host.

• fsid | string

  fsid of the ceph cluster. To generate a suitable value use `uuid` . This configuration element is mandatory and the service will fail on install if it is not provided.

• harden | string

  Apply system hardening. Supports a space-delimited list of modules to run. Supported modules currently include os, ssh, apache and mysql.

• key | string

  Key ID to import to the apt keyring to support use with arbitary source configuration from outside of Launchpad archives or PPA's.

• loglevel | int

  Default: 1

  Mon and OSD debug level. Max is 20.

• monitor-count | int

  Default: 3

  How many nodes to wait for before trying to create the monitor cluster this number needs to be odd, and more than three is a waste except for very large clusters.

• monitor-secret | string

  This value will become the mon. key. To generate a suitable value use: . ceph-authtool /dev/stdout --name=mon. --gen-key . This configuration element is mandatory and the service will fail on install if it is not provided.

• nagios_context | string

  Default: juju

  Used by the nrpe-external-master subordinate charm. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.

• nagios_servicegroups | string

  A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup

• prefer-ipv6 | boolean

  If True enables IPv6 support. The charm will expect network interfaces to be configured with an IPv6 address. If set to False (default) IPv4 is expected. NOTE: these charms do not currently support IPv6 privacy extension. In order for this charm to function correctly, the privacy extension must be disabled and a non-temporary address must be configured/available on your network interface.

• source | string

  Optional configuration to support use of additional sources such as: - ppa:myteam/ppa - cloud:trusty-proposed/kilo - http://my.archive.com/ubuntu main The last option should be used in conjunction with the key configuration option. Note that a minimum ceph version of 0.48.2 is required for use with this charm which is NOT provided by the packages in the main Ubuntu archive for precise but is provided in the Ubuntu cloud archive.

• sysctl | string

  Default: { kernel.pid_max : 2097152, vm.max_map_count : 524288, kernel.threads-max: 2097152 }

  YAML-formatted associative array of sysctl key/value pairs to be set persistently. By default we set pid_max, max_map_count and threads-max to a high value to avoid problems with large numbers (>20) of OSDs recovering. very large clusters should set those values even higher (e.g. max for kernel.pid_max is 4194303).

• use-direct-io | boolean

  Default: True

  Configure use of direct IO for OSD journals.

• use-syslog | boolean

  If set to True, supporting services will log to syslog.
