I am trying to use Godaddy's K8s client to patch a CRD.
Following their example, I have tried:
Translating their example directly:
const patchService = await client.apis["serving.knative.dev"].v1alpha1.namespaces('default').services.patch({body: {
"spec": {
"template": {
"spec": {
"containers": [
{
"image": "docker.io/quantomworks/mcsh-site:" + build.metadata.annotations['hook-to-k8s']
}
]
}
}
}
}})
console.log("Patch result:")
console.log(patchService)
Creating a service patch object manually, following this example.
const servicePatchObject = [{ op: "replace", path: "/spec/runLatest/configuration/revisionTemplate/spec/container/image", value: "docker.io/quantomworks/mcsh-site:" + build.metadata.annotations['hook-to-k8s']}]
const patchService = await client.apis["serving.knative.dev"].v1alpha1.namespaces('default').services('mcserverhosting-net-site').patch({body: servicePatchObject})
Taking a yaml file that I can run with contents that match a successful kubectl patch services.serving.knative.dev mcserverhosting-net-site --type json -p
- op: replace
path: /spec/runLatest/configuration/revisionTemplate/spec/container/image
value: docker.io/quantomworks/mcsh-site:latest
And then posting it directly
const patchService = await client.apis["serving.knative.dev"].v1alpha1.namespaces('default').services('mcserverhosting-net-site').patch(servicePatch)
All result in the following error:

It's not a complete answer, but an alternative. Switched put
instead of patch
. kubectl apply
equivalent. Also aware that I didn't moc the spec version proplery for API type services.service.knative.dev
, but this was alreay done, undone, and then re-corrected for sanity in the code. Still didn't accept anything I gave it. A cleaner solution would be nice. Currently having to increment [ResourceVersion][1]
this way, which isn't bad.
