Method Details

serviceMetadata

public static org.springframework.cloud.kubernetes.commons.discovery.ServiceMetadata serviceMetadata(io.fabric8.kubernetes.api.model.Service service)

getApplicationNamespace

public static String getApplicationNamespace(io.fabric8.kubernetes.client.KubernetesClient client,
 @Nullable
 String namespace,
 String configurationTarget,
 org.springframework.cloud.kubernetes.commons.KubernetesNamespaceProvider provider)

this method does the namespace resolution. Namespace is being searched according to the order below.

     1. from incoming namespace, 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)
           5. from KubernetesClient::getNamespace, which is implementation specific.
 

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

client - fabric8 Kubernetes client

Returns:

application namespace

Throws:

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