kubebuilder VS Transmission

The Spin operator uses the Kubebuilder framework and contains a Spin App Custom Resource Definition (CRD) and controller. It watches Spin App Custom Resources and realizes the desired state in the K8s cluster. Aside from the immediate benefits gained by running Wasm workloads in k8s, additional optimizations such as Horizontal Pod Scaling (HPA) and k8s Event-driven Autoscaling (KEDA) can be achieved in a pinch.

kubebuilder: brew install kubebuilder

The operator that I've been working on is designed to manage the full lifecycle of a QuestDB database instance, including version and hardware upgrades, config changes, backups, and (eventually) recovery from node failure. I used the Operator SDK and kubebuilder frameworks to provide scaffolding and API support.

Recently, I've been spending a lot of time writing a Kubernetes operator using the go operator-sdk, which is built on top of the Kubebuilder framework. This is a list of a few tips and tricks that I've compiled over the past few months working with these frameworks.

Since we built our operator using the Kubebuilder framework, most standard monitoring tasks were handled for us out-of-the-box. Our operator automatically exposes a rich set of Prometheus metrics that measure reconciliation performance, the number of k8s API calls, workqueue statistics, and memory-related metrics. We we were able to ingest these metrics into pre-built dashboards by leveraging the grafana/v1-alpha plugin, which scaffolds two Grafana dashboards to monitor Operator resource usage and performance. All we had to do was add these to our existing Grafana manifests and we were good to go!

I wrote a CSI driver and some operators. I admire K8s, because you can find solution to almost any problem in the source code - API versioning, load balancing, request throttling, optimistic concurrency, security, and much much more. I recommend https://book.kubebuilder.io/ It is similar to Operator SDK, but without Openshift-specific stuff. It gradually introduces you to many k8s concepts, and follows design patterns that k8s uses internally.

Do you mean this: https://book.kubebuilder.io/ ?

A better way to write an operator these days is to use kubebuilder [1].

My complaint is that I have seen orgs write operators for random stuff, often reinventing the wheel. Lot of operators in orgs are result of resume driven development. Having said that it often comes handy for complex orchestration.

Why bake libtransmission into the app instead of just using the transmission daemon's RPC?

What you've done actually makes it harder to use, because in order to configure any of transmission's settings (ports, connection/torrent connection limits, bandwith limits, etc) the user needs to dig around to find the transmission config folder and then manually edit JSON with a text editor - because your client doesn't expose any of transmissions numerous settings [1] to the user except for choosing the download folder.

I'm not sure why anyone would want to use this instead of Flood [2] or even old Transmission Web Control [3]

Grab this file. Install Transmission on Mac or Deluge on Win. Optional: run a VPN if you're in the US(mostly) and worried about your ISP sending you a cease-and-desist notice. Open the file using the app you installed. Wait. It should start within a minute or two and download progress will be seen. Speed depends on how many people are sharing it. Any issues, let me know.

Why "NO TORRENT"? Just get TransmissionBT and torrent whatever you want

Its intresting you mention that, before reading your reply I went and created a post in the Q n A section, asking for help about this very thing and I linked to the same GitHub issue you linked to here. I have yet to get a reply lol.here

transmission can run as a headless server with a web gui

Get a VPN like Windscribe(set windscribe firewall to on instead of auto), forward your port via their website. Use a good torrent client like https://transmissionbt.com/ set that port in the options, and add a blocklist https://github.com/Naunter/BT\_BlockLists/raw/master/bt\_blocklists.gz
