Reset the root password for the bitnami deployed mariadb, description in the GIST itself

What??

FIX YOUR MARIADB ROOT PASSWORD

Why??

Because you don't want it broken.

OK

I keep going back to this comment as all bitnami's helm charts have an issue when using ArgoCD with the default username/password for MariaDB where the secret is re-generated everytime.

The correct solution is to use "existingSecret" in the values.yaml OR a secret for an external database.

What I do now since I do not have crazy traffic is to have 1 MariaDB in my Kubernetes Cluster and create a user and a database for each application that uses MariaDB, make sure to give the correct scope for each user.

In any case here's the solution for the default behaviour:

Solution from @lknite in this comment: bitnami/charts#10439 (comment)

Solution

For someone who comes across this later, I was able to get things back up and working by:

edit the mariadb statefulset

kubectl edit statefulset wordpress-<website>-mariadb & setting a command to run: set a command to be run instead of the default from the container

        - /opt/bitnami/mariadb/bin/mysqld_safe
        - --skip-grant-tables
        - --skip-networking
        - --datadir=/bitnami/mariadb/data

now reset the root@% password

k exec -it wordpress-<website>-mariadb-0 -- bash

mysql -u root
> use mysql;
> FLUSH PRIVILEGES;
> ALTER USER 'root'@'%' IDENTIFIED BY '<password to use from your secret>';

modify the statefulset to remove the command added earlier & kill the pod
