The content\_id is considered when matching images between the source and destination to decide which images to mirror. By varying this value you can mirror disjoint sets of images from the same source into a single glance, either by using multiple deployments of this charm, or by using a tool such as sstream-mirror-glance, and they will not interfere with each other. Here is a more interesting example value: ``` com.example.customstack.{region}:ubuntu:celery-worker ``` Currently the only available substitution is "region". Any other attempted substitutions will break the sync script. * custom\_keyring | string base64-encoded GPG keyring for verifying the simplestreams mirror signature. Only required when mirroring a custom user-created repository, defaults to /usr/share/keyrings/ubuntu-cloudimage-keyring.gpg which is used to sign cloud-images.ubuntu.com. Can be produced with the following command: gpg --no-default-keyring --keyring gnupg-ring:custom\_keyring.gpg --keyserver keyserver.ubuntu.com --recv-keys KEYID * custom\_properties | string Space separated list of custom properties (format key=value) to be set in glance for all synced images e.g. hw\_firmware\_type, hw\_vif\_multiqueue\_enabled. * frequency | string Default: daily cron job frequency - one of ['hourly', 'daily', 'weekly'] * hypervisor\_mapping | boolean Enable configuration of hypervisor-type on synced images. . This is useful in multi-hypervisor clouds supporting both LXD and KVM. * ignore\_proxy\_for\_object\_store | boolean Default: True Controls whether Juju model proxy settings are going to be used by sstream-mirror-glance when connecting to object-store endpoints from the Keystone catalog. * key | string DEPRECATED - option no longer used and will be removed * mirror\_list | string Default: [{url: 'http://cloud-images.ubuntu.com/releases/', name\_prefix: 'ubuntu:released', path: 'streams/v1/index.sjson', max: 1, item\_filters: ['release~(trusty|xenial|bionic|focal|jammy)', 'arch~(x86\_64|amd64)', 'ftype~(disk1.img|disk.img)']}] YAML-formatted list of simplestreams mirrors and their configuration properties. Defaults to downloading the released images from cloud-images.ubuntu.com. * 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 * name\_prefix | string Default: auto-sync/ This is prefixed to the object name when uploading to glance. * region | string Default: RegionOne OpenStack region to operate in. * run | boolean Enable cron-based synchronisation * snap-channel | string Default: stable Snap channel to install simplestreams snap from * source | string DEPRECATED - option no longer used and will be removed * ssl\_ca | string base64-encoded SSL CA to use to verify certificates from keystone and glance if using SSL on the services. * 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\_swift | boolean Default: True Controls whether swift will be used for image metadata storage or not. If set to False, image metadata will not be written to object store while images will still be synced to Glance. * user\_agent | string Default: glance-simplestreams-sync User agent to use when requesting images from image servers listed in the mirror\_list. * visibility | string Default: public Visibility to apply to stored images. Possible values are 'public', 'private', 'community', and 'shared'.
