How to create k8s deployment using kubernetes-client in c#?

Closing this issue (Resolved)

Reference: https://github.com/Azure/autorest/issues/931

Cause of issue: incorrect version of Kubernetes ApiVersion.

Solution: get and replace ApiVersion from kubernetes api.

Can also handle the exception using:

        try        {            var result = client.CreateNamespacedDeployment(deployment, namespace);        }        catch (Microsoft.Rest.HttpOperationException httpOperationException)        {            var phase = httpOperationException.Response.ReasonPhrase;            var content = httpOperationException.Response.Content;        }

For the full clarity and future visitors, it's worth to mention, what is exactly behind this bad request error (code: 400) returned from API server, when using your code sample:

"the API version in the data (extensions/v1beta1) does not match the expected API version (apps/v1)"

Solution:

 ApiVersion = "extensions/v1beta1" -> ApiVersion = "apps/v1"
