Trying to get a basic mautic instance running on my local machine using docker desktop.
Using the basic docker-compose example from github, here is my docker-compose.yml:
name: xxxx-yyyy-services
volumes:
xxyy-data:
networks:
xxyy:
x-mautic-volumes:
&mautic-volumes

- ./mautic/media/images:/var/www/html/docroot/media/images:z
# - ./cron:/opt/mautic/cron:z # Uncomment this line to customize your cron configuration

You can see with the commented out command in the mysql server that I tried setting mysql-native-password=ON.
I have also tried just using the root user to connect to the mysql DB with the same issue.
The issue I am seeing in the log for mautic_web is:
MySQL response contained error: amysqladmin: connect to server at 'xxyy-mysql' failed
error: 'Access denied for user '"root"'@'172.18.0.3' (using password: YES)'
(Where “root” is whichever user I try. The same message occurs for xxxxyyyy_user)
In the MySql logs, I see this error:
2025-10-06T10:06:50.658664Z 41 [Warning] [MY-013360] [Server] Plugin sha256_password reported: ''sha256_password' is deprecated and will be removed in a future release. Please use caching_sha2_password instead'
In MySql (which is up and running correctly), when I do:
SELECT user, host, plugin from mysql.user;
The xxxxyyyy_user has a plugin of caching_sha2_password
I have tried changing that plugin to mysql_native_password and I got a similar, but slightly different error.
What is the correct configuration for MySql in docker-compose so that mautic can connect?
It is worth noting that I can successfully connect to the MySql instance from the command line or other database tools using both the root user and the xxxxyyyy_user. MySql seems to be running fine and works as expected.
