Hi, with kubectl apply … deployments are defined in yaml files, which seems to be a very static approach. Basically I would like to dynamicallly create unique deployments per customer but based on the same deployment-yaml. Meaning I would need to pass eg. a customer id dynamically rather than def…

Well, as far a I understand Helm its not declarative, isn’t it? However, my final goal is to kick off this dynamic deployment creation through a PHP Client using the REST API. I think Helm has no libraries available to support this easily, right?

Helm can be a little bit of both. You’d provide it a template (Chart) and it would populate that with a values file. So if you needed a common template that would be populated by changing variables it would fit nicely. Each deployment (chart + values) would be it’s own unique deployment. The values…

Yes, but Helm seems to be not declarative though. Eg. if you look a the helm deployments you won’t find kubectl.kubernetes.io/last-applied-configuration annotations there. The helm developer guide covers more the templates than the external available apis. So right now I tend to build on the late…

Ahh ya, if you’re relying on kubectl things would be different. Helm does keep track of its deployments and you can see things via the helm history command. If you want to keep things going through kubectl you can use Helm strictly for templating using the helm template . command. This will do the t…

No, that’s not what I need. kustomize just applies overlays which are still stored in static yaml files. What I want is to apply the dynamically created content of a eg. a kustomization.yaml through a REST API. without the obligation to store it in the filesystem in advance. I consider to pass inf…

I can’t think of anything else off the top of my head that doesn’t rely on having files somewhere. There might be something out there though. Sorry I couldn’t be of more help. Good luck!

No problem at all and thanks for your assistance. I will do some more research, however maybe I will have to stick with files anyway.

If you find something let us know. I’m interested to hear what solution you find.

Have you looked into Helm at all? I think that might be a good fit for this case. https://helm.sh/
