Use go debugger's delve with Kubernetes
Some time ago I faced a bug where it was untrivial to understand the precise workflow.
One of the beauties of the open-source is that the user can also take the pilot seat ;-)
In this article, we will see how to compile the Dell CSI driver for PowerFlex with a debugger, configure the driver to allow remote debugging, and attach an IDE.
Velero backup to PowerScale S3 Bucket
Velero is one of the most popular tools for backup and restoring of Kubernetes resources.
PowerScale is Dell's leading scale-out NAS solution, supporting many different access protocols including S3!
Dell Container Storage Module - A GitOps-ready platform!
One of the very first things I do after deploying a Kubernetes cluster is to install a CSI Driver to provide persistent storage to my workloads; coupled with a GitOps workflow, it takes seconds literally to be able to run stateful workloads.
Build a custom Dell CSI Driver
With all the Dell CSI drivers and dependencies being open-source, anyone can tweak them to fit a specific use case.
This article demonstrates creating a patched version of a Dell CSI Driver for PowerScale.
CSI PowerFlex performance
Containerized workloads and microservices are designed to be ephemeral. It can be to answer the needs of scalability (via Pod autoscaling) or because they process data for a short period (ML workload). Every day stateful apps are becoming a bigger part of Kubernetes workloads.
Blazing fast kubectl completion
You can use cache_builder from kubectl-fzf to speed-up completion and use a systemd unit to start it on login.
Implement Tanzu on private networks with VyOS
With a virtual router (here VyOS ), and proper routing table, it is possible to implement VMware Tanzu on private networks without NSX-T.
Use cert-manager with Karavi Observability
Check out how Prometheus metrics & Grafana dashboard work for CSI PowerFlex from this karavi observability video .
Learn more about karavi and karavi-observability from their respective repositories.
PersistentVolume static provisioning
In this article, we will discuss and present a script (ingest-static-pv.sh ) for Persistent Volume static provisioning of Dell CSI Drivers for PowerMax, PowerStore, PowerScale, PowerFlex, and Unity.
