Docker/Podman - Cannot get MySQL connection to work

[Russell Jones]

Hi all,

I am struggling to get the Docker container to be able to login to the MariaDB container. The error I am getting is:

[2022-03-16T16:15:32,504] ERROR pool.ConnectionPool - Unable to create initial connections of pool.
java.sql.SQLException: Driver:org.mariadb.jdbc.Driver@58486deb returned null for URL:"jdbc:mysql://127.0.0.1:3306/rundeck?autoReconnect=true&useSSL=false"

Googling that error is telling me it believes the URL is in a bad format, or that it does not recognize the driver.

Below is my podman-compose file. Do y'all see anything wrong with it? What am I messing up?

Thanks!

Replying back for benefit of others - Got this solved. It was the double quotes around my URL causing the issue. :-)
