Need help finding a good software stack for a private Kubernetes cluster

I need a:

1. CMS (with webhooks)
2. Something that easily lets me deploy stuff (as in either a git triggered deployment or just uploading a zip file)
3. and an easy-to-use static file hosting server that supports dynamic uploads since I need to do Incremental static regeneration (I have played around with caddy and cepth a bit)

Edit: if anyone is still willing to help I'd be really helpful. I'm not a veteran of self-hosting
