How to Run Docker on Raspberry Pi for Industrial Applications
Setting up Docker on Raspberry Pi is simple. Setting it up correctly for industrial use is different.
Step 1: Choose the Right Hardware
- Raspberry Pi 4 or Pi 5
- Sufficient RAM (4GB minimum, 8GB preferred)
- Reliable storage — industrial SD or USB SSD
Step 2: Install a Stable OS
- Raspberry Pi OS Lite (64-bit)
- Minimal setup preferred — fewer moving parts
Step 3: Install Docker
- Use the official Docker convenience install script
- Verify ARM64 image compatibility for everything you deploy
Step 4: Optimise for Performance
- Limit container CPU and memory with explicit resource caps
- Monitor CPU, memory and I/O continuously
- Avoid noisy logging to local disk
Step 5: Secure the System
- Restrict SSH access and disable defaults
- Use secure credentials and key-based auth
- Keep both the OS and Docker engine patched
Common Mistakes
- Running too many containers per device
- Ignoring storage limits and SD wear
- No security configuration beyond defaults
Final Thought
Setup is easy. Stability takes planning.
