operator VS shell-operator

Now, for the actual deployment of Tekton Pipeline and Triggers - I mentioned an installation via Tekton Operator which might seem like the fastest and the best way to get up and running with everything preconfigured, the operator however (at the time of writing) lacks any actual documentation, so you would need to dig around quite a lot to find any explanation as to how things work, which wouldn't be that big of an problem for me personally. The real problem here though, is that the Operator in OperatorHub isn't up to date and I couldn't find current build/image which renders it more or less useless. I'm sure this will change at some point when Tekton Operator is a little more mature (so keep an eye on it's repository), but until then, other installation options should be used.

Maybe, the Shell operator is a good tool for that?

Shell-operator to parse logs and make action after the pod crash.

Argo workflow can trigger from k8s objects but may be a bit more than you need, shell-operator may be good enough https://github.com/flant/shell-operator for a quick win

I used https://github.com/flant/shell-operator to write a simple Kubernetes operator that automatically creates subdomains for your services by patching an existing ingress.

If you are more into lightweight and common use cases, look at metacontroller or the shell-operator.

Believe it or not, you can write a Kubernetes operator using simple shell scripts: https://github.com/flant/shell-operator

You could use something like shell operator, metacontroller, or operator-sdk to run a command against your load balancer's API whenever a LoadBalancer service is created.

https://github.com/flant/shell-operator should get you quite far but this sounds like the process should just shut itself down when that case is hit...

shell-operator is already used in KubeSphere's ks-installer, Confluent's Kafka DevOps solution, Deckhouse Kubernetes platform, and more. All documentation is available in the project's GitHub repo — if you feel it might be interesting for your needs, give it a try! Any feedback is warmly welcome.
