This change adds the capability to rename the subcloud after bootstrap or during subcloud rehome operation. Added a field in the database to separate the region name from the subcloud name. The region name determines the subcloud reference in the Openstack core, through which it is possible to access the endpoints of a given subcloud. Since the region name cannot be changed, this commit adds the ability to maintain a unique region name based on the UUID format, and allows subcloud renaming when necessary without any endpoint impact. The region is randomly generated to configure the subcloud when it is created and only applies to future subclouds. For those systems that have existing subclouds, the region will be the same as on day 0, that is, region will keep the same name as the subcloud, but subclouds can be renamed. This topic involves changes to dcmanager, dcmanager-client and GUI. To ensure the region name reference needed by the cert-monitor, a mechanism to determine if the request is coming from the cert-monitor has been created. Usage for subcloud rename: dcmanager subcloud update <subcloud-name> --name <new-name> Usage for subcloud rehoming: dcmanager subcloud add --name <subcloud-name> --migrate ... Note: Upgrade test from StarlingX 8 -> 9 for this commit is deferred until upgrade functionality in master is restored. Any issue found during upgrade test will be addressed in a separate commit Test Plan: PASS: Run dcmanager subcloud passing subcommands: - add/delete/migrate/list/show/show --detail - errors/manage/unmanage/reinstall/reconfig - update/deploy PASS: Run dcmanager subcloud add supplying --name parameter and validate the operation is not allowed PASS: Run dcmanager supplying subcommands: - kube/patch/prestage strategies PASS: Run dcmanager to apply patch and remove it PASS: Run dcmanager subcloud-backup: - create/delete/restore/show/upload PASS: Run subcloud-group: - add/delete/list/list-subclouds/show/update PASS: Run dcmanager subcloud strategy for: - patch/kubernetes/firmware PASS: Run dcmanager subcloud update command passing --name parameter supplying the following values: - current subcloud name (not changed) - different existing subcloud name PASS: Run dcmanager to migrate a subcloud passing --name parameter supplying a new subcloud name PASS: Run dcmanager to migrate a subcloud without --name parameter PASS: Run dcmanager to migrate a subcloud passing --name parameter supplying a new subcloud name and different subcloud name in bootstrap file PASS: Test dcmanager API response using cURL command line to validate new region name field PASS: Run full DC sanity and regression Story: 2010788 Task: 48217 Signed-off-by: Cristian Mondo <cristian.mondo@windriver.com> Change-Id: Id04f42504b8e325d9ec3880c240fe4a06e3a20b7
