k8s plugin sometime swaps the pod name with the node name

XMLWordPrintable

      We are seeing about 10-60 crashed jobs per day with the client seeming to have mixed up the node/pod names in its invocation which leads to us getting 404's from the api server.

      It begins by us launching a job which then sends out a pod template then once everything has started up. Sometime we will be running for a while before a shell call start to fall over or sometime it starts falling over right away.

      It attempts to send shell command to the pod then due to it being the wrong pod name (node name) it fails.

      The main crux of it is this line here:

      io.fabric8.kubernetes.client.KubernetesClientException: pods "ip-*-*-*-*.us-west-2.compute.internal" not found

       

      I've censored the actual ip address, but this is a node name not a pod name so that indicates to me that something is mixing the two up in the plugin.
