This adds new lifecycle update operation so that a semantic check lifecycle
step is run against the "to" application during application-update.
The application specific lifecycle code requires a custom semantic check
using the new hook (e.g., similar to the following):
if hook_info.lifecycle_type == constants.APP_LIFECYCLE_TYPE_SEMANTIC_CHECK:
if hook_info.operation == constants.APP_UPDATE_OP:
if hook_info[LifecycleConstants.EXTRA].get(LifecycleConstants.TO_APP, False):
return self.update_check(app_op._dbapi, app)
* VirtualBox: AIO-SX
* Created example application changes for platform-integ-apps using
semantic check shown above, and prototype update_check() routine.
* Tested the following for both pass and fail semantic check cases:
system application-update platform-integ-apps-1.0-29.tgz
* Tested that apps on the application-update are okay on an upgrade,
as invoked in upgrade-scripts/65-k8s-app-upgrade.sh.
i.e., system upgrade-activate
Semantic check passes, update proceeds to 1.0-29 "to" version,
the 1.0-27 "from" version is cleaned up.
Semantic check fails, application recovery proceeds to "from" version,
the 1.0-29 "to" version is cleaned up.
Example when semantic check fails,
| platform-integ-apps | 1.0-27 | platform-integration-manifest | manifest.yaml \
| applied | Application update from version 1.0-27 to version 1.0-29 aborted. \
Application recover to version 1.0-27 completed. Please check logs for details
