Docker network

The default network bridge has no name/alias resolution capabilites! To use container names/alias assign the container to a user-defined bridge network.

Containers on the default bridge network can only access each other by IP addresses, unless you use the --link option, which is considered legacy. On a user-defined bridge network, containers can resolve each other by name or alias. Source:


Plesk web services fails

I just had an issue with a new Plesk Plesk Obsidian 18.0.45 installation, where the web services were broken after doing some migration from another Plesk instance. The web service was not controllable anymore from the Plesk frontend.The Plesk error log says The service node must be a web server node.

The solution

plesk repair installation
plesk repair web
/usr/local/psa/admin/bin/nginxmng -d
/usr/local/psa/admin/bin/nginxmng -e
service apache2 restart
