SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for cms-db failed: Temporary failure in name resolution

Update :

I used this manual from the forum : Xibo CMS with Docker on Ubuntu 22.04

There is a problem with the configuration : cms_custom-ports.yml

volumes:
- “./shared/db:/var/lib/mysql:Z”
restart: always
environment:
- MYSQL_DATABASE=cms
- MYSQL_USER=cms
- MYSQL_RANDOM_ROOT_PASSWORD=yes
mem_limit: 1g
env_file: config.env
cms-xmr:
image: [Package xibo-xmr · GitHub](http://ghcr.io/xibosignage/xibo-xmr:0.11)

cms-memcached:
image: memcached:alpine
command: memcached -m 15

cms-quickchart:

Add the following lines.
Add the lines to the cms-db

networks:
default:
aliases:
- mysql

If not the mysql docker container keeps running into problems/restart etc.
After added this lines, the mysql docker container runs stable.

Xibo : Can you add this lines in the template files of cms_custom-ports.yml ??
