A great article describing how to send log from Kubernetes Clusters to a centralized system (here Elasticsearch) on AWS. Monitoring is a key part when we are talking K8s for many reasons that are quite obvious but sometimes forgotten. I will never repeat enough this. Monitoring if the key for happy systems, happy administrators and … Read more Configuring Fluentbit on VMware Cloud PKS for…

NSX-T loses synch w/ vCenter inventory, but statuses don’t appear to show an issue. Basically, you add a host to a vCenter cluster, NSX-T bits should start to automatically installing on new host. Assuming you’ve created a Transport Node Profile and associated w/ the cluster. The problem is that NSX-T doesn’t see the new host and its link to the compute manager (vCenter) looks fine.
|Looks fine, Y U NO WORK!?|
So what’s going on here?
This appears to affect NSX-T 2.5 and 2.5.1. Cause is unknown.
Restart the cm-inventory service on each NSX-T mgmt/controller node using API or CLI.
If you were to query the status of the cm-inventory via API or CLI, you could query all 3 manager/controller nodes and get a status of running. Even if the primary node associated w/ the VIP, if configured, is not necessarily in charge of inventory. So you could restart the cm-inventory service till you are blue in the face and get nowhere because another node is actually responsible for maintaining the sync.
Even so, with this particular problem, they would all look healthy. You’d have to dig into the logs to find the issue. Thankfully Nathan Pyle from VMware helped us find the issue and provided us w/ a workaround solution until the bug is addressed in a future version.

Making a post on this as I experienced this first hand. Issue is, after reboot, some pods will not run. Specifically, vco and pg. This can be verified by executing the following command in one of the node: kubectl get pods –all-namespaces You’ll notice some pods will be CrashLoop state. To resolve, the following KB will help: https://kb.vmware.com/s/article/78235 For new installs: https://kb.vmware.com/s/article/76870 Hope that helps!
Why do you need this. If you work with VMware NSX on daily basis you should care about Backup & Restore procedure. According to VMware you can schedule NSX Manager backup and think you are on safe side but restore procedure requires to perform full NSX Manager restore and then… Continue reading

NSX-T Edge provides computational power to deliver IP routing and services. We can deploy multiple Edge nodes up to 10 to form an NSX-T Edge cluster. An NSX Edge cluster is a group of homogeneous nodes with common properties that provide high availability for the Edge nodes.. Having an NSX-T edge cluster will ensure that at […]
Lately I was updating a couple of my scripts, and when I re-used my script that automatically updates AWS records for Let’s Encrypt DNS challenges, I realised that I never stored my AWS credentials anywhere, but I was just using those cached into my powershell environment. Time to have some proper credential management.
