…mware-tanzu#3092) * Add default field to BSL CRD Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Add a new flag `--default` under `velero backup-location create` add a new flag `--default` under `velero backup-location create` to specify this new location to be the new default BSL. Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Add a new default field under `velero backup-location get` add a new default field under `velero backup-location get` to indicate which BSL is the default one. Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Add a new sub-command and flag under `velero backup-location` Add a new sub-command called `velero backup-location set` sub-command and a new flag `velero backup-cation set --default` to configure which BSL is the default one. Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Add new flag to get the default backup-location Add a new flag `--default` under `velero backup-location get` to displays the current default BSL. Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Configures default BSL in BSL controller When upgrade the BSL CRDs, none of the BSL has been labeled as default. Sets the BSL default field to true if the BSL name matches to the default BSL setting. Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Configures the default BSL in BSL controller for velero upgrade When upgrade the BSL CRDs, none of the BSL be marked as the default. Sets the BSL `.spec.default: true` if the BSL name matches against the `velero server --default-backup-storage-location`. Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Add unit test to test default BSL behavior Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Update check which one is the default BSL in backup/backup_sync/restore controller Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Add changelog Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com> * Update docs locations.md and upgrade-to-1.6.md Signed-off-by: JenTing Hsiao <jenting.hsiao@suse.com>
