I have created a mysql container like so:
docker run --name nextcloud-mysql -e MYSQL_ROOT_PASSWORD=ABC -e MYSQL_DATABASE=nextclouddb -e MYSQL_USER=nextclouduser -e MYSQL_PASSWORD=123 -d mysql:8
I have also created a nextcloud container like so:
docker run -d --network mynetwork --ip 192.168.1.227 --restart unless-stopped nextcloud
In my browser I call up 192.168.1.227 and am greeted by the first run wizard.
I enter the following info:
- username: admin
- password: ***
MySQL/MariaDB:
- database user: nextclouduser
- database password: 123
- database name: nextclouddb
- database host: nextcloud-mysql
Result:
Error message:
Error while trying to create admin user: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution
Any help in getting this cleared up would be great.

Your nextcloud-mysql and nextcloud containers in different networks. Mysql I think in network bridge, nextcloud app in network mynetwork
You need to make both containers are on same network, add same network parameters to command for mysql containers as for application.example: --network mynetwork --ip 192.168.1.228
I think that mynetwork is your physical network and I'm not sure that docker can correctly resolve name nextcloud-mysql in your case, You may need to write IP address a database in application config.
