Hello All,
I have been struggling with this for quite a while now and just cannot find a solution to how to change the IP address range that the containers pull address from. right now my containers are pulling 172 addresses which seems to work for Plex but is breaking nextcloud.
My environment:
TruenasSCALE: 25.04.0
Interface IP’s: 192.168.1.100 & 192.168.1.200
Nextcloud
Plex
I had Nextcloud running until I tried to add files_external which needed to be activated by “occ app:enable files_external”. As soon as I executed that directive Nextcloud broke and I started receiving an error complaining about a 172 address.
Investigating further I did a “docker ps” command and found the id of the container running nextcloud.
At the bottom (for readability) is the output of the “docker inspect ” command for that container. As you see it is using 172 addresses. I would like to use all 192.168.0.0/16 addresses for all of my containers to simplify my routing internally but for the life of me cannot figure out how to change the pool of IP’s that docker pulls from.
I have tried editing the entries in the daemon.json file from 172.17.0.0/12 to 192.168.0.0/16 but no luck and when I reboot it gets overwritten anyway:
