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. * audit-middleware | boolean Enable Keystone auditing middleware for logging API calls. * config-flags | string Comma-separated list of key=value config flags. These values will be placed in the heat.conf [DEFAULT] section. * database | string Default: heat Database name * database-user | string Default: heat Username for database access * debug | boolean Enable debug logging. * dns-ha | boolean Use DNS HA with MAAS 2.0. Note if this is set do not set vip settings below. * encryption-key | string Encryption key used for authentication info in database. * ha-bindiface | string Default: eth0 Default network interface on which HA cluster will bind to communication with the other members of the HA Cluster. * ha-mcastport | int Default: 5959 Default multicast port number that will be used to communicate between HA Cluster nodes. * haproxy-client-timeout | int Client timeout configuration in ms for haproxy, used in HA configurations. If not provided, default value of 90000ms is used. * haproxy-connect-timeout | int Connect timeout configuration in ms for haproxy, used in HA configurations. If not provided, default value of 9000ms is used. * haproxy-queue-timeout | int Queue timeout configuration in ms for haproxy, used in HA configurations. If not provided, default value of 9000ms is used. * haproxy-server-timeout | int Server timeout configuration in ms for haproxy, used in HA configurations. If not provided, default value of 90000ms is used. * harden | string Apply system hardening. Supports a space-delimited list of modules to run. Supported modules currently include os, ssh, apache and mysql. * instance-user | string The default user for new instances. This option is deprecated as of Juno. If left empty, Heat will use the default user set up with your cloud image (for OS::Nova::Server) or 'ec2-user' (for AWS::EC2::Instance). * max-stacks-per-tenant | int Maximum number of stacks any one tenant may have active at one time. * 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 are 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 * openstack-origin | string Default: yoga 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 e.g. . cloud:- cloud:-/updates cloud:-/staging cloud:-/proposed . See https://wiki.ubuntu.com/OpenStack/CloudArchive for info on which cloud archives are available and supported. . NOTE: updating this setting to a source that is known to provide a later version of OpenStack will trigger a software upgrade unless action-managed-upgrade is set to True. * os-admin-hostname | string The hostname or address of the admin endpoints created for heat in the keystone identity provider. . This value will be used for admin endpoints. For example, an os-admin-hostname set to 'heat.admin.example.com' with ssl enabled will create the following admin endpoints for ceilometer: . https://heat.admin.example.com:8004/ * os-admin-network | string The IP address and netmask of the OpenStack Admin network (e.g. 192.168.0.0/24) . This network will be used for admin endpoints. * os-internal-hostname | string The hostname or address of the internal endpoints created for heat in the keystone identity provider. . This value will be used for internal endpoints. For example, an os-internal-hostname set to 'heat.internal.example.com' with ssl enabled will create the following internal endpoints for ceilometer: . https://heat.internal.example.com:8004/ * os-internal-network | string The IP address and netmask of the OpenStack Internal network (e.g. 192.168.0.0/24) . This network will be used for internal endpoints. * os-public-hostname | string The hostname or address of the public endpoints created for heat in the keystone identity provider. . This value will be used for public endpoints. For example, an os-public-hostname set to 'heat.example.com' with ssl enabled will create the following public endpoints for ceilometer: . https://heat.example.com:8004/ * os-public-network | string The IP address and netmask of the OpenStack Public network (e.g. 192.168.0.0/24) . This network will be used for public endpoints. * 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. * rabbit-user | string Default: heat Username to request access on rabbitmq-server. * rabbit-vhost | string Default: openstack RabbitMQ virtual host to request access on rabbitmq-server. * region | string Default: RegionOne OpenStack Region * ssl\_ca | string SSL CA to use with the certificate and key provided - this is only required if you are providing a privately signed ssl\_cert and ssl\_key. * ssl\_cert | string SSL certificate to install and use for API ports. Setting this value and ssl\_key will enable reverse proxying, point Heat's entry in the Keystone catalog to use https, and override any certificate and key issued by Keystone (if it is configured to do so). * ssl\_key | string SSL key to use with certificate specified as ssl\_cert. * ttl | int Default: 3600000 TTL in MS for heat queues in the openstack vhost. Defaults to 1 hour, but can be tuned up or down depending on deployment requirements. * use-internal-endpoints | boolean Openstack mostly defaults to using public endpoints for internal communication between services. If set to True this option will configure services to use internal endpoints where possible. * use-policyd-override | boolean If True then use the resource file named 'policyd-override' to install override YAML files in the service's policy.d directory. The resource file should be a ZIP file containing at least one yaml file with a .yaml or .yml extension. If False then remove the overrides. * use-syslog | boolean Setting this to True will allow supporting services to log to syslog. * verbose | boolean Enable verbose logging. * vip | string Virtual IP(s) to use to front API services in HA configuration. . If multiple networks are being used, a VIP should be provided for each network, separated by spaces. * vip\_cidr | int Default: 24 Default CIDR netmask to use for HA vip when it cannot be automatically determined. * vip\_iface | string Default: eth0 Default network interface to use for HA vip when it cannot be automatically determined. * worker-multiplier | float The CPU core multiplier to use when configuring worker processes for this service. By default, the number of workers for each daemon is set to twice the number of CPU cores a service unit has. This default value will be capped to 4 workers unless this configuration option is set.
