Examples with PodOperationsImpl io.fabric8.kubernetes.client.dsl.internal.PodOperationsImpl used on opensource projects

Example 1 with PodOperationsImpl

use of io.fabric8.kubernetes.client.dsl.internal.PodOperationsImpl in project syndesis by syndesisio.

the class KubernetesSupport method watchLog.

/*
     * Feeds the controller of the given podName to the callback handler for processing.
     *
     * We do this instead of using the watchLog() feature of the k8s client lib because it really sucks due to:
     *  1. You can't configure the timestamps option or the sinceTime option.  Need to resume log downloads.
     *  2. It seems to need extra threads..
     *  3. It might be hiding some of the http failure conditions.
     *
