octant VS keda

I just can't understand why people don't give Octant (https://octant.dev/) a try.

Octant https://octant.dev/

Have you seen Octant https://octant.dev/? (It's a question not a recommendation).

Octant

Like the Kubernetes Dashboard, Octant is an open-source web interface for visualizing your clusters and applications. The solution supports multiple plugins via a core gRPC API, making Octant extensible and richly featured. Like other tools, it provides real-time updates on the health and performance of your cluster’s objects plus related objects. This detailed metrics tracking is meant to simplify the debugging process and highlight problems before they become threatening. Building off of kubectl and kustomize, Octant is a simple and reliable tool for managing the Kubernetes system as a whole.

Octant is one of the best-known tools in the Kubernetes dashboard space. It’s a project that Bryan Liles built a lot of back when he was at Heptio. I remember Bryan talking on Twitter about a new tool he was working on that would help folks think about what was running in their Kubernetes clusters, and that was Octant. VMWare acquired Heptio after that, and now Bryan and Octant are both at VMWare.

Let us wait for a few moments before the URL is reachable. Meanwhile, let us install Octant from here.

If you’re looking for a set of valuable tools that collectively work as a powerful dashboard, Octant may be ideal.

It seems you want something like KEDA (https://keda.sh)

Most just utilize out of the box macro resources available in HPA.

For more advanced use cases there is keda - https://keda.sh/

Thankfully KEDA operator was already part of the cluster, and all Robin had to do was create a ScaledObject manifest targeting the Dispatch ScaleUp event, based on the rabbitmq_global_messages_received_total metric from Prometheus.

Keda

KEDA introduces event-driven scaling to Kubernetes workloads. It integrates with Kubernetes Horizontal Pod Autoscalers and can scale pods based on external metrics from services like databases and message queues (Kafka, RabbitMQ, MongoDB).

# update version 2.8.2 if required kubectl apply -f https://github.com/kedacore/keda/releases/download/v2.8.2/keda-2.8.2.yaml

This is traditionally a AWS Lambda usecase - or an OpenFaas kind of usecase. But very recently i discovered https://keda.sh/ and it seems it is specifically meant for this in a kubernetes environment.

If you deploy the application to Amazon EKS, you can also consider using KEDA to auto-scale your consumer application based on the number of messages in the MSK topic.
