During my Cloud Director 10.4.1 to 10.5 upgrade, I hit a repeated issue during the database upgrade step. Unable to upgrade the database: org.postgresql.util.PSQLException: ERROR: could not open shared memory segment “/PostgreSQL.839369758”: No such file or directory Or sometimes this: Unable to upgrade the database: org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend I dug through many, MANY logs. At first I thought it was the resources on my VCD cell, so I increased CPU and RAM allocations and the upgrade was successful.

With the release of VMware Cloud Director 10.5 to VMware Cloud Providers, I wanted to jump on it early and get a blog post about the upgrade process and new features. Except, I’ve been battling a small issue getting the upgrade through in my lab! Enjoy the read. My environment consists of: Cloud Director 10.4.1 (single cell) Container Service Extension 4.0.3 App LaunchPad 2.1.2 For this post, I’ll only be upgrading Cloud Director to 10.

I recently posted how to upgrade VMware Cloud Director’s Container Service Extension from 4.0.1 to 4.0.3. The next step in the journey is to configure the new CAPVCD provider (1.0.1) on any existing Kubernetes clusters deployed by CSE, and then upgrade those clusters from TKG 1.5.4 images to TKG 1.6.1 images. Wait, what am I updating? Kubernetes clusters deployed by CSE include what’s called a Cluster API Provider (CAP) for VMware Cloud Director (VCD) which is where we get CAPVCD.

I’ve got VMware Cloud Director Container Service Extension (CSE) 4.0.1 running in my lab to test and demo Kubernetes Clusters as-a-service in Cloud Director. CSE 4.0.3 was released on the 20th of April 2023 and came with significant improvements. Let’s take a look at my current environment: VCD 10.4.1 CSE UI Plugin 4.0.1 CSE Server 4.0.1 vSphere 7.0U3 NSX-T 4.0.1.1 NSX ALB (Avi) 22.1.2-9086 Based on the above, I don’t need to change a single thing for CSE 4.

Bill of Materials VMware vRealize Log Insight 8.10.2 VMware Cloud Director 10.4.1 VMware Cloud Director App Launchpad Extension 2.1.2 Photon OS 4.0 (for ALP) Have you deployed the Application Launchpad (ALP) extension into VMware Cloud Director in your Cloud Platform? You’re probably wondering how you can get those pesky logs out from your ALP servers. I found a great post by Vysakh Nair detailing how to use the vRLI Agent to forward logs from Cloud Director appliances.

I’ve had some partners ask for a reference that maps VCD, CSE, TKG images and TKr versions in a single table. Behold! The Cloud Director column details the VCD version, CSE details the version of CSE compatible with the VCD builds. TKG Images column lists the versions of Tanzu Kubernetes Grid images that are supported by CSE, and the Tanzu Kubernetes Release (TKr) column details the Kubernetes releases available for the TKG Images version in the list.
