UnsupportedMediaType when patching ingress

[SaschaHeyer]

Hi

when patching a ingress we get the following error message

{
      kind: 'Status',
      apiVersion: 'v1',
      metadata: {},
      status: 'Failure',
      message: '415: Unsupported Media Type',
      reason: 'UnsupportedMediaType',
      details: {},
      code: 415
    }

Kubernetes Version: 1.14.10-gke.27

This is almost certainly because the Content-type header is set to application/json instead of application/strategic-merge-patch+json or something similar.

See #440 which discussed the same issue.

Closing this issue since I believe the question is answered. If you still have problems, please place them in #440

It would be good to include full patch example in examples directory. I also got the same issue. My fixed code looks like:

  const k8sNetworkingApi = kc.makeApiClient(k8s.NetworkingV1beta1Api);
  const patchedIngress = {
    metadata: {
      annotations: {
        'nginx.ingress.kubernetes.io/cors-allow-origin': '*'
      }
    }
  }
  k8sNetworkingApi.patchNamespacedIngress(ingressName, namespace, patchedIngress, undefined, undefined, undefined, undefined,
    { headers: { 'content-type': 'application/merge-patch+json' } })

We would happily take a PR adding a complete patch example to the examples directory.

I filed: #450

To track this, @saxicek if you have the time to create a PR that would be awesome!
