I have an existing MySQL 8 docker container at localhost:3308 which is working.
I just pulled the latest WordPress docker image and ran it with
docker run --name some-wordpress -p 8080:80 -d wordpress
//localhost:8080/wp-admin/setup-config.php displays correctly bit will not connect to the MySql instance. The error page gives no diagnostic info so I can’t tell what specifically isn’t working. Just “Error establishing a database connection”
I set the following:
Database Name: wordpress [I created a schema called wordpress in MySql assuming “Database” = “Schema”]
Username: root
Password: password
Database host: localhost:3308
Table prefix: wp_
The user has full access to the wordpress schema.
What am I missing/doing wrong?

I have set up a server to host multiple websites according to this tutorial: //blog.ssdnodes.com/blog/host-multiple-ssl-websites-docker-nginx/
I have also configured a docker-compose.yml for wordpress like they did in example 2 in the same tutorial. But when I open the website, I get an "Error establishing a database connection" Error. I remember doing this a few months back with everything working fine, but I cant remember what I did differently.
This is the error message I receive [multiple times] after typing docker-compose up
wp_test | MySQL Connection Error: [1045] Access denied for user 'wordpress'@'172.20.0.9' [using password: YES]

My docker-compose.yml file looks like this:

volumes:
- db_data:/var/lib/mysql
restart: always
environment:

WORDPRESS_DB_PASSWORD: wordpress

I have tried to stop and start the the image, as suggested here: //www.reddit.com/r/docker/comments/ahzv5d/wordpress_cant_connect_to_mysql/
I have also tried another wordpress docker-config.yml and added the nginx paramaters myselve, but got the same error message //docs.docker.com/compose/wordpress/
EDIT I got new error messages
