Can't connect to mysql pod in Kubernetes when using Secrets for password (Access denied)

Question

I try to setup a mysql database in Kubernetes. I configured a ConfigMap to store the Database name and a Secret that contains the root password, the user and the password fo

Answer 1

You need to give the access to client machine to connect mysql database.

replace the address with your desktop ip and run this command on mysql database. then test the connection.

GRANT ALL PRIVILEGES ON *.* TO 'root'@''   WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'   WITH GRANT OPTION;
FLUSH PRIVILEGES;

The way you created secret is not correct. remove and create it like this. I tested in my cluster it worked.

kubectl create secret generic db-credentials --from-literal=mysql-root-password=Test1234 --from-literal=mysql-user=testadm --from-literal=mysql-password=Test1234
