ashb opened a new pull request #4883: [AIRFLOW-4053] Fix KubePodOperator Xcom on Kube 1.13.0 URL: https://github.com/apache/airflow/pull/4883 Make sure you have checked _all_ steps below. ### Jira https://issues.apache.org/jira/browse/AIRFLOW-4053 ### Description Newer versions of Kube return "failed" events for the side car container when the ^C causes the python process to exit with 1 Kube 1.13 runs a different number of kube-dns pods (2 by default, 1.9 and 1.10 ran only 1) so the setup scripts needed changing a little bit. To get a Kube 1.13 cluster I had to upgrade minikube, and it no longer works on a dist without systemd installed (#systemdsucks) so I had to update the travis dist to xenial which is no bad thing! (This version of minikube doesn't need the localkube bootstrapper set anymore, it handles driver=none much more gracefully) ### Tests - [x] Existing tests good enough, and still pass ### Commits - [x] My commits all reference Jira issues in their subject lines, and I have squashed multiple commits if they address the same issue.
