I used Tekton for the last two years, and I didn't like it. One of the reasons is the community split around Tekton Hub between versions 3 and 4. Another reason is that it's not very Kubernetes native. While you write YAML, there are a subset of instructions that limit you regarding mundane things you can do on Kubernetes but Tekton doesn't support, such as mounting different PersistentVolumeClaims or setting tasks by platforms or nodes (amd64, arm64, etc).

I was so frustrated that I created my own Kubernetes-native CI/CD solution. Currently in development phases (when it is done, I will publish it here). This one uses real native Kubernetes components (jobs). You create Webhooks that launch Workflows, and Workflows can launch other Workflows or Jobs. You can do anything in a Job with no limitations other than Kubernetes itself. Take a look if you want: https://github.com/jlsalvador/simple-cicd

I looked at Tekton, but the complexity of doing simple things put me off. I have been running woodpecker which now has Kubernetes support.

Installing the Helm Chart for the Woodpecker agent gives K8s support with no special configuration needed. My needs are simple but I have been really impressed with how easy it has been.
