connect in interface JMXConnector

Overrides:

connect in class org.jolokia.client.jmxadapter.JolokiaJmxConnector

Throws:

IOException

createAdapter

protected org.jolokia.client.jmxadapter.RemoteJmxAdapter createAdapter(org.jolokia.client.J4pClient client)
                                                                throws IOException

Get a kubernetes client for the specified local context (in ~/.kube/config)

Parameters:

context - , specify context, null for current context

Returns:

client configured for the specified context - potentially recycled as the setup is expensive (YAML parsing is amazingly slow)

resetKubernetesConfig

public static void resetKubernetesConfig()

Manually reset any cached config. To be uses in case you have changed your kubeconfig

expandAndProbeUrl

protected org.jolokia.client.J4pClient expandAndProbeUrl(io.fabric8.kubernetes.client.KubernetesClient client,
 Map<String,Object> env)

Returns:

a connection if successful

Throws:

MalformedURLException

 io.fabric8.kubernetes.client.KubernetesClient client,
 StringBuilder url,
 HashMap<String,String> headers)

Probe whether we find Jolokia in given namespace, pod and path
