kubelet minikube Back-off restarting failed container

Question

Hi Guys,

I am trying to create one mysql pod in kubernetes cluster. But I got this below error.

$ kubectl describe pods mysql 

Normal   Scheduled  <unknown>          default-scheduler  Successfully assigned default/mysql to minikube
Normal   Pulled     15s (x4 over 58s)  kubelet, minikube  Container image "mysql:5.7" already present on machine
Normal   Created    15s (x4 over 58s)  kubelet, minikube  Created container mysql-con
Normal   Started    15s (x4 over 57s)  kubelet, minikube  Started container mysql-con
Warning  BackOff    2s (x6 over 55s)   kubelet, minikube  Back-off restarting failed container

How can I solve this?

Hi@akhtar,

You may get this error if you didn't provide environment variable. Mysql pod needs environment variable to launch a container. You can use the below given variables in your code.

MYSQL_ROOT_PASSWORD:
MYSQL_USER:
MYSQL_PASSWORD:
MYSQL_DATABASE:

Hope this is helpful.
