Metabase pod is running but not ready, continuously crasehs.

First of all I am new to Kubernets so I am not sure if this is a me problem or issue with the code!
After I follow up on the turorial I get two pods, one for posgres and one for metabase. The postgres pod seems to behave correctly but the metabase pod is running but is not ready. Then the metabase crashes and restarts continuously.
Output:
```%> kubectl get pods \n
NAME READY STATUS RESTARTS AGE
database-5486bd697b-fh58m 1/1 Running 0 8m57s
metabase-6555cd59d5-dm4xg 0/1 CrashLoopBackOff 6 (2m7s ago) 8m57s
```
