How to use docker bridge link containers

[DearTanker]

As we know, if we use bridge network mode, all docker containers will get a dedicated IP like 172.17.0.*. 

But when you reboot some docker containers, those IPs will change. so it is very inconvenient to use IP.

I don't want to use unraid IP, because I think it will let all data transfer back and forth in the router.

 

Is there any way to use something like hostname to links containers on unraid?

Why would you directly use those IPs?  Usual way to communicate with a container would via the host IP and applicable port.

Like "unraid-ip:123 --> router --> unraid-ip:456 --> router --> unraid-ip:123".

As long as your server is wired, data will not traverse the router unless it being used by a wireless client or if the client is on a different subnet than the server. Meaning, if you are trying to read from InfluxDB container from Grafana container, via the server IP, the data will not traverse your router. It will be horseshoed through the eth0 interface.

 

Make sense?
