Problem with the provider-template template https://github.com/crossplane/provider-template

[Filippo Giorgi]

Hi, I'm developing a provider for observing and calculating ML metrics. The moment I start my provider.yaml file it is created but from Healty = False, reporting this error message.

Message: cannot initialize parser backend: couldn't find "package.yaml" file after checking 1426 files in the archive (annotated layer: false): EOF What should package.yaml be? I attach my provider code:

Hi, 

Please see https://github.com/crossplane/crossplane/blob/main/design/one-pager-package-format-v2.md on details for packaging format and what a package.yaml is. 

You could use https://explore.ggcr.dev to inspect your image and compare it with an existing provider, as a real world example, see its contents for provider-helm: https://explore.ggcr.dev/fs/xpkg.upbound.io/upbound/provider-helm@sha256:449e0a091de563a7301198f126c07f01ce798bf179fb5f098bc742b4fd5e1bd8/package.yaml 

However, I believe something wrong with how you build and package your provider. Since you're using https://github.com/crossplane/provider-template, you should be able to build & push your provider by following https://github.com/crossplane/crossplane/discussions/3817#discussion-4921460

Hope this helps.

Hi,
thanks for the answer, I build and package my provider by following the developing tutorial on this link https://github.com/crossplane/provider-template. For the point 7. Replace the default controller and ProviderConfig implementations with your own, I only modified my file /provider-template/apis/sample/v1alpha/mytype_types.go and /provider-template/internal/controller/mytype/mytype.go . After that I used make reviewable and make build, I apply the crds, I pushed the build in my repository and I create a second yaml file, the one I send in the previous mail, for apply the provider in my cluster and I had the error of the package.yaml.
So I don't know what it could go wrong. 

Another question, is it a problem use the latest version of crossplane? Or I have to use the crossplane version 1.16.0, because in the go.mod file it use that.

Thanks for the answer!
