For series=Trusty we support UCA for openstack-release= * juno * kilo * ... . NOTE: updating this setting to a source that is known to provide a later version of OpenStack will trigger a software upgrade. . NOTE: when openstack-origin-git is specified, openstack specific packages will be installed from source rather than from the openstack-origin repository. openstack-origin-git: type: string default: description: | Specifies a default OpenStack release name, or a YAML dictionary listing the git repositories to install from.

Defaults to 512MB. vcpu-pin-set: type: string default: description: | Sets vcpu_pin_set option in nova.conf which defines which pcpus that instance vcpus can or cannot use.

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: type: string default: description: | A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup. # Network configuration options # NOTE: by default all access is over 'private-address' use-internal-endpoints: default: False type: boolean description: | 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. 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. cpu-mode: type: string default: description: | Set to 'host-model' to clone the host CPU feature flags; to 'host-passthrough' to use the host CPU model exactly; to 'custom' to use a named CPU model; to 'none' to not set any CPU model.

Defaults to 'host-passthrough' for ppc64el, ppc64le if no value is set. cpu-model: type: string default: description: | Set to a named libvirt CPU model (see names listed in /usr/share/libvirt/cpu_map.xml). Only has effect if cpu_mode='custom' and virt_type='kvm|qemu'. # Storage configuration options libvirt-image-backend: type: string default: description: | Tell Nova which libvirt image backend to use. Supported backends are rbd, lvm and qcow2. If no backend is specified, the Nova default (qcow2) is used. Note that rbd imagebackend is only supported with >= Juno. rbd-pool: type: string default: 'nova' description: | RBD pool to use with Nova libvirt RBDImageBackend. Only required when you have libvirt-image-backend set to 'rbd'. rbd-client-cache: type: string default: description: | Enable/disable rbd client cache. Leaving this value unset will result in default Ceph rbd client settings being used (rbd cache is enabled by default for Ceph >= Giant). Supported values here are "enabled" or "disabled". ceph-osd-replication-count: type: int default: 3 description: | This value dictates the number of replicas ceph must make of any object it stores withing the nova rbd pool. Of course, this only applies if using Ceph as a backend store. Note that once the nova rbd pool has been created, changing this value will not have any effect (although it can be changed in ceph by manually configuring your ceph cluster). # Other configuration options sysctl: type: string default: description: | YAML formatted associative array of sysctl values, e.g.: '{ kernel.pid_max : 4194303 }' manage-neutron-plugin-legacy-mode: type: boolean default: True description: | If True nova-compute will install neutron packages for the plugin stipulated by nova-cloud-controller.

Please do not enable this on new deployments. # Huge page configuration - off by default hugepages: type: string default: description: | The pecentage of system memory to use for hugepages eg '10%' or the total number of 2M hugepages - eg "1024". For a systemd system (wily and later) the prefered approach is to enable hugepages via kernel parameters set in MAAS and systemd will mount them automatically. 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.
