October 5, 20232 yr Hello there! I finally managed to build my fileserver, set up the backup, shoved all the data to it, etc, pp. I'm now in a place to set up my services. Docker + CA is the choice I gladly follow since there are a lot applications almost ready to run out there. I ran into startup sequence problems though. Consider the following container instances: PGSQL on 172.0.0.3, Redis on 172.0.0.4. When Redis - for any reason - comes up before PGSQL it will obtain 172.0.0.3 and therefore mess up both, Redis and PGSQL for all dependent services. In the real world this is easily solved by using a DNS server to address those containers by redis://redis.dockernet and sql://pgsql.dockernet I know I can set a container hostname by using `--hostname [host]` and could build a dnsmasq Container to handle the DNS/DHCP. The question is how to get the Unraid Docker Engine accepting (not interfering with) this configuration with no/minimal changes in the UI and/or is there a better solution to this problem? I can't be the only one .. Basically I want to recreate the functionality of this plugin: https://github.com/containers/dnsname/blob/main/README_PODMAN.md There are some forum threads dealing with DNS already but all seem to try to establish DNS to Unraids outside world while I'm happy if I can reliably talk between my containers using their internal hostnames or an entirely different subnet altogether. https://xkcd.com/979/ 🙂
