Docker

I run several Docker containers managed with Dockge on an LXC in Proxmox. Recently, I encountered an issue where my LXC became unresponsive, and new containers were unreachable. Even the LXC itself stopped responding to pings. After some investigation, I discovered that Docker was assigning an IP range that conflicted with my home network. This quick guide outlines how I resolved the issue.

I have a Raspberry Pi Zero W that runs a docker image of rtl_433, a popular data receiver for decoding data from popular sensors broadcasting on frequencies such as 433.92 Mhz or 915 MHz. For reasons unknown to me, thing stop working. I haven't been able to find out what causes the issue, but I did find that restarting the docker container seems to get things back on track. Setting up an automation that automatically reboots the container is not very elegant, but it works and ended seemingly endless troubleshooting.
