If you're having SSL-related issues when connecting Adminer to an Azure MySQL database, try out this very helpful answer, with the following nuances:
- no need for client key or client certificate, i.e., discard environment
DB_SSL_CERTand the respective volumes
- use only
DB_SSL_CAand its respective volume with the certificate provided by Azure (see more details here)
Note: these instructions assume you have Adminer running as a Docker container, but the same arguments being passed to the Adminer plugin login-ssl should apply nonetheless.
