deployment of mysql not intaking root password set in secret-CodePudding

I've googled and googled and not sure what I'm doing wrong. it seems how ever way i try to set the root password for mysql, it doesn't seem to work. I'm currently testing out the below(which i've seen plastered over the internet) and this too doesn't work. I'm not getting any errors, logs do not show any errors, and honestly at this point, I'm kind of lost and would appreciate some help.

secrets.yaml file:

apiVersion: v1
kind: Secret
metadata:
  name: mysqlpass
  namespace: gitea
type: Opaque
data:
  password: "cGFzc3dvcmQxMjM="

and my deployment file has the following set:

 spec:
      containers:
      - image: mysql/mysql-server:latest
        imagePullPolicy: IfNotPresent
        name: gitea-mysql
        env:
          # Use secret in real usage
        - name: MYSQL_ROOT_PASSWORD
          valueFrom:
            secretKeyRef:
              name: mysqlpass
              key: password

my current pod logs:

CodePudding user response：

I remember having a similar problem with Docker. I ended deleting (CAREFUL HERE) any folder created during the creation of the previous mysql docker container. One of those folders has the password for the root user and unless this is deleted or changed it will continue with any other mysql container used to replace the old one.

CodePudding user response：

fixed it! turns out it was an issue with the way I had set up persistent volumes. The way my cluster is set up is that all pods have a pv on an nfs drive. i had forgotten to specify which server the nfs drive was to be mounted on. After making that fix, i saw files populating the pv, and the set password to work.

in my defense, i blame me not connecting the dots of the empty pv directories to my sleep deprivation.

For anyone else that comes across this similar issue, check to make sure everything else is set correctly. Even though your PV might not error out, it could still be set up incorrectly.
