options: openstack-origin: default: distro type: string description: | Repository from which to install. May be one of the following: distro (default), ppa:somecustom/ppa, a deb url sources entry, or a supported Ubuntu Cloud Archive release pocket. Supported Ubuntu Cloud Archive sources include: cloud:- cloud:-/updates cloud:-/staging cloud:-/proposed NOTE: updating this setting to a source that is known to provide a later version of OpenStack will trigger a software upgrade unless the action-managed-upgrade configuration option is in play. block-device: default: sdb type: string description: | Device to be used to back Swift storage. May be any valid block device or a path and size to a local file (/path/to/file.img|$sizeG), which will be created and used as a loopback device (for testing only). Multiple devices may be specified as a space-separated list of devices. If set to "guess", the charm will attempt to format and mount all extra block devices (this is currently experimental and potentially dangerous). overwrite: default: "false" type: string description: | If true, charm will attempt to unmount and overwrite existing and in-use block-devices (WARNING). ephemeral-unmount: type: string default: description: | Cloud instances provide ephermeral storage which is normally mounted on /mnt. . Setting this option to the path of the ephemeral mountpoint will force an unmount of the corresponding device so that it can be used as a swift storage device. This is useful for testing purposes (cloud deployment is not a typical use case). zone: default: 1 type: int description: | Swift storage zone to request membership. Relevant only when the swift-proxy charm has been configured for manual zone assignment (the default). This should be changed for every service unit. object-server-port: default: 6000 type: int description: Listening port of the swift-object-server. container-server-port: default: 6001 type: int description: Listening port of the swift-container-server. account-server-port: default: 6002 type: int description: Listening port of the swift-account-server. worker-multiplier: default: 1.0 type: float description: | The CPU multiplier to use when configuring worker processes for the account, container and object server processes. object-server-threads-per-disk: default: 4 type: int description: | Size of the per-disk thread pool used for performing disk I/O. 0 means to not use a per-disk thread pool. It is recommended to keep this value small, as large values can result in high read latencies due to large queue depths. A good starting point is 4 threads per disk. prefer-ipv6: type: boolean default: False description: | 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. account-max-connections: default: 2 type: int description: | Number of connections allowed to the account rsync stanza. container-max-connections: default: 2 type: int description: | Number of connections allowed to the container rsync stanza. object-max-connections: default: 2 type: int description: | Number of connections allowed to the object rsync stanza. object-replicator-concurrency: default: 1 type: int description: | Number of replication workers to spawn. object-rsync-timeout: default: 900 type: int description: | Max duration of a partition rsync (in seconds). nagios-check-params: default: "-m -r 60 180 10 20" type: string description: String appended to nagios check nagios_context: default: "juju" type: string description: | 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: default: "" type: string description: | A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup action-managed-upgrade: type: boolean default: False description: | If True enables openstack upgrades for this charm via juju actions. You will still need to set openstack-origin to the new repository but instead of an upgrade running automatically across all units, it will wait for you to execute the openstack-upgrade action for this charm on each unit. If False it will revert to existing behavior of upgrading all units on config change. harden: default: type: string description: | Apply system hardening. Supports a space-delimited list of modules to run. Supported modules currently include os, ssh, apache and mysql. sysctl: type: string default: description: | YAML formatted associative array of sysctl values, e.g.: '{ kernel.pid_max : 4194303 }' statsd-host: default: '' type: string description: | Enable statsd metrics to be sent to the specified host. If this value is empty, statsd logging will be disabled. statsd-port: default: 3125 type: int description: | Destination port on the provided statsd host to send samples to. Only takes effect if statsd-host is set. statsd-sample-rate: default: 1.0 type: float description: | Sample rate determines what percentage of the metric points a client should send to the server. Only takes effect if statsd-host is set. enable-firewall: type: boolean default: True description: | By default the swift-storage charm will use the UFW firewall to protect storage daemons. This option allows the administrator to disable this feature. allow-ufw-ip6-softfail: description: | When this option is set to True the charm will disable the IPv6 support in ufw in case ip6tables couldn't be activated, situations where this could happen is in a LXC container running on top of a host that doesn't have loaded the ip6_tables. If this option is False (the default) and ip6_tables module couldn't be loaded, the charm will fail to install. type: boolean default: False encrypt: default: false type: boolean description: | Encrypt block devices used by swift using dm-crypt, making use of vault for encryption key management; requires a relation to vault. xfs-inode-size: default: 512 type: int description: XFS inode size to use for block devices. storage-region: default: 1 type: int description: | Swift storage region to request membership. Relevant only when the swift-proxy charm has been configured with the Swift Global Cluster feature. object-server-port-rep: default: 6010 type: int description: Listening port of the swift-object-replicator server. container-server-port-rep: default: 6011 type: int description: Listening port of the swift-container-replicator server. account-server-port-rep: default: 6012 type: int description: Listening port of the swift-account-replicator server.
