Hi
I am currently going through the Kubernetes Chapter and I am running into an issue with the deployment. The prometheus container keeps going into a crashbackloop.
Normal Pulled 10m (x5 over 11m) kubelet, vagrant Container image "prom/prometheus:v2.1.0" already present on machine Normal Created 10m (x5 over 11m) kubelet, vagrant Created container prometheus Warning BackOff 83s (x49 over 11m) kubelet, vagrant Back-off restarting failed container
It comes and then all the services shutdown

Anyone else bump into this issue?
Running K8s 1.14.1, with containerd as my runtime.
