Learn about configurations >

• enable-auto-restarts | boolean

  Default: True

  Allow the charm and packages to restart services automatically when required.

• nagios_context | string

  Default: juju

  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

  Comma separated list of nagios servicegroups for the service checks.

• ovn-exporter-channel | string

  Default: stable

  The snap channel to install the prometheus-ovn-exporter from. Setting this option to an empty string will result in the snap not being installed or removed if it has already been installed.

• ovn-source | string

  Overlay repository from which to install OVS+OVN.

  The default for this configuration option is determined at charm runtime.

  When charm is deployed into a fresh environment on Ubuntu 20.04 (Focal Fossa), the default will be 'cloud:focal-ovn-22.03'.

  When charm is upgraded or deployed into a fresh environment on a different series the default will be to not use the overlay repository.

  To disable the overlay repository, set this option to 'distro'.

  Note that updating this setting to a source that is known to provide a later version of OVN will trigger a software upgrade.

• ovsdb-server-election-timer | int

  Default: 4

  Raft leader election timeout in seconds. The charm allows a value between 1 and 60 seconds. . The Open vSwitch ovsdb-server default of 1 second may not be sufficient for a loaded cluster where the database server may be too busy serving requests to respond to elections in time. . Using a higher value will increase the time to discover a real failure, but you must weigh that against the risk of spurious leader flapping and the unwanted churn that entails. . NOTE: The ovsdb-server will refuse to decrease or increase the value of this timer more than 2x the current value. The charm will compensate for this and decrease / increase the timer in increments, but care should be taken to not decrease / increase the value too much in one operation.

• ovsdb-server-inactivity-probe | int

  Default: 60

  Maximum number of seconds of idle time on connection to client before sending an inactivity probe message.

  The Open vSwitch ovsdb-server default of 5 seconds may not be sufficient depending on type and load of the CMS you want to connect to OVN.

• snapd_refresh | string

  How often snapd handles updates for installed snaps. The default (an empty string) is 4x per day. Set to "max" to check once per month based on the charm deployment date. You may also set a custom string as described in the 'refresh.timer' section here: https://forum.snapcraft.io/t/system-options/87

• source | string

  Default: caracal

  Repository from which to install packages.

  May be one of the following:

  distro (default) ppa:somecustom/ppa (PPA name must include UCA OpenStack Release name) deb url sources entry|key id or a supported Ubuntu Cloud Archive pocket.

  Supported Ubuntu Cloud Archive pockets include:

  cloud:xenial-pike cloud:xenial-queens cloud:bionic-rocky

  Note that updating this setting to a source that is known to provide a later version of Ceph will trigger a software upgrade.
