How Environment Variables Indicate Deployment State
Once invoked, a pre- or post-processing script can determine in which deployment state (install, import, delete, uninstall, import rollback, or install rollback) it is running by checking the environment variables BTAD_ChangeRequestAction, BTAD_InstallMode and BTAD_HostClass.
The following table describes the combinations of the three variables that indicate the different deployment states.
| Deployment State | Expected Values |
|---|---|
| BTAD_ChangeRequestAction | |
| Import without overwrite flag | Create |
| Import with overwrite flag | Update |
| Install | Update |
| Uninstall | Delete |
| Import rollback | Delete |
| Install rollback | Delete |
