Method Detail

watch

Watch watch(Watcher<T> watcher)

Watch returns Watch interface that watches requested resource

Parameters:

watcher - Watcher interface of Kubernetes resource

watch interface Watch

watch

Watch watch(io.fabric8.kubernetes.api.model.ListOptions options,
            Watcher<T> watcher)

Watch returns Watch interface that watches requested resource

The passed in options may be modified as a side-effect of this call.
Values that already exist at this context, such as the labels, fields, and resourceVersion will be overridden on the passed in options regardless of initial values.

Parameters:

options - options available for watch operation

watcher - Watcher interface of Kubernetes resource

Returns:

watch interface Watch

watch

@Deprecated
Watch watch(String resourceVersion,
            Watcher<T> watcher)

Please use watch(ListOptions, Watcher) instead, it has a parameter of resourceVersion

Watch returns Watch interface that watches requested resource from specified resourceVersion

Parameters:

resourceVersion - resource version from where to start watch

watcher - Watcher interface of Kubernetes resource

Returns:

watch interface Watch

streamingList

default CompletableFuture<String> streamingList(Consumer<T> onItem)

Helper method to use the WatchList feature to list resources. A watch is used under the covers, but will be terminated after the initial events.
Not specifying a resourceVersion on the context or using 0 will perform a "consistent read" from the time at which the request started processing.

Parameters:

onItem - a consumer to be called for each item

Returns:

a CompletableFuture that provides the terminal resourceVersion, or any underlying exception during processing. It may be cancelled to terminate the streamingList operation early
