Resolved A custom hostname for Mysql8 run via Docker

[marek.tenus]

I've been running mysql8 container via Docker using a Plesk's extension.
When I connect my app with the container, I use its IP (MySQL container) as hostname. But as you know, this IP is dynamically assigned.
It means that after restarting the container IP/rebooting system, it can be changed.
My question is: How can I set up a custom hostname for my MySQL with the Plesk's extension?

example

before in my app config

MYSQL_HOST=<CONTAINER_IP>

after in my app config

MYSQL_HOST=mysql

I hope I've explained it clearly.

I solved that by running docker via console and setting up a static IPs for my containers. Because of it, you can't to change settings with Plesk's extension.
