Raspberry Pi 4 SSD Running Raspberry OS Lite: Troubleshooting Random Hangs with Docker Containers (Home Assistant, Pi-Hole, NetDaemon)
In this article, we will discuss how to set up and run Docker containers for Home Assistant, Pi-Hole, and NetDaemon on a Raspberry Pi 4 with an SSD and Raspberry OS Lite. We will also cover some potential solutions to the issue of random hangs that can occur with this setup.
Prerequisites
- Raspberry Pi 4 with an SSD
- Raspberry OS Lite installed on the SSD
- Docker installed on the Raspberry Pi
Setting up Docker Containers
To set up Docker containers for Home Assistant, Pi-Hole, and NetDaemon, you will first need to create a docker-compose.yml file. Here is an example of what this file might look like:
```
version: '3'
services:
homeassistant:
image: homeassistant/home-assistant:stable
volumes:
- /path/to/your/config:/config
restart: unless-stopped
pi-hole:
image: pihole/pihole:latest
volumes:
- /path/to/pihole/data:/etc/pihole
- /path/to/pihole/logs:/var/log/pihole
ports:
- "53:53/udp"
- "53:53/tcp"
- "67:67/udp"
- "80:80"
- "443:443"
restart: unless-stopped
netdaemon:
image: netdaemon/netdaemon:latest
volumes:
- /path/to/netdaemon/config:/app
environment:
- TZ=America/Los_Angeles
restart: unless-stopped
```
Make sure to replace the placeholders with the actual paths on your system. Once you have created this file, you can start the containers by running the following command:
```
docker-compose up -d
```
Troubleshooting Random Hangs
If you are experiencing random hangs with this setup, there are a few potential solutions you can try:
-
Increase the swap size: By default, Raspberry OS Lite has a very small swap size, which can cause issues when running multiple Docker containers. You can increase the swap size by following the instructions in this guide.
-
Disable IPv6: Some users have reported that disabling IPv6 can help resolve issues with random hangs. You can disable IPv6 by adding the following line to the
/etc/dhcpcd.conffile:``` interface eth0 noipv6rs ``` -
Use a different kernel: Some users have reported that using a different kernel, such as the one from the thibmaek/raspberrypi-kernel repository, can help resolve issues with random hangs.
