Method Details

createApiClientForInformerClient

public static io.kubernetes.client.openapi.ApiClient createApiClientForInformerClient()

kubernetesApiClient

public static io.kubernetes.client.openapi.ApiClient kubernetesApiClient()

getApplicationNamespace

public static String getApplicationNamespace(String namespace,
 String configurationTarget,
 org.springframework.cloud.kubernetes.commons.KubernetesNamespaceProvider provider)

this method does the namespace resolution for both config map and secrets implementations. It tries these places to find the namespace:

    1. from a normalized source (which can be null)
    2. from a property 'spring.cloud.kubernetes.client.namespace', if such is present
    3. from a String residing in a file denoted by `spring.cloud.kubernetes.client.serviceAccountNamespacePath`
              property, if such is present
           4. from a String residing in `/var/run/secrets/kubernetes.io/serviceaccount/namespace` file,
                  if such is present (kubernetes default path)

If any of the above fail, we throw a NamespaceResolutionFailedException.

Parameters:

namespace - normalized namespace

configurationTarget - Config Map/Secret

provider - the provider which computes the namespace

Returns:

application namespace

Throws:

org.springframework.cloud.kubernetes.commons.config.NamespaceResolutionFailedException - when namespace could not be resolved
