hypolas/registrator repository overview

⁠Registrator (With Network priority)

I added to the "registrator" the ability to select docker networks name or subnetwork has been prioritized in the tools.

Under certain conditions and it does not matter the order of the Docker network, the eth0 card is not reassembled as the first network. This creates a problem with Consul's healthcheck, for example, where the IP address Consul used is unreachable by Consul.

This therefore allows you to have several networks identified in your container but to prioritize the one you want.

In the event that no IP is found in the list of defined networks, registrator will show the first IP (standard operation).
