Deleting stale kubernetes clusters in vCD

Unlike the previous version the CSE 4.x is a stateless appliance and its data is stored in VMware Cloud Director Database.  The cluster creation and deletion compared with CSE 3.x version has improved. Besides, there are some scenarios where the cluster deletion is failing even when the "Force Delete" option is chosen. We can use vCD API explorer to delete it, the following are the API queries you can execute  Under definedEntity POST /1.0.0/entities/{id}/resolve DELETE /1.0.0/entities/{id}

VCD Upgrade failure via VCPLCM

One of the nicest tool available for vCD Life cycle management is VMware Cloud Provider Lifecycle Manager. We were able to successfully upgrade our POC environment from 10.3.3 to 10.4.1.1, which gave us confidence in upgrading the production environment using VCPLCM 1.5. Unfortunately, the upgrade was failing in the production environment and I wanted to share the experience and solution for it.  This tool makes our life easier to do all the prerequisite checks and takes snapshots and take backups of DB before doing the upgrade. It was failing at the stage of "Upgrade_DB" with the below task in VCPLCM. We could see it was timing out with a Postgres IO timeout error in the vCD logs. The logs in VCPLCM and VCD are not very informative and also the upgrade failure results in an automatic rollback to dig further.   ["2023-05-19 13:13:43,812Z"] 2023-05-19 13:13:43,811 - DEBUG - Starting with VCD upgrade.
