My kubernetes pods keep crashing with “CrashLoopBackOff” but I can't find any log

Question

This is what I keep getting:

[root@centos-master ~]# kubectl get pods
NAME               READY     STATUS             RESTARTS   AGE
nfs-server-h6nw8   1/1           


        

Answer 1

I had similar issue but got solved when I corrected my zookeeper.yaml file which had the service name mismatch with file deployment's container names. It got resolved by making them same.

apiVersion: v1
kind: Service
metadata:
  name: zk1
  namespace: nbd-mlbpoc-lab
  labels:
    app: zk-1
spec:
  ports:
  - name: client
    port: 2181
    protocol: TCP
  - name: follower
    port: 2888
    protocol: TCP
  - name: leader
    port: 3888
    protocol: TCP
  selector:
    app: zk-1

kind: Deployment
