If you’ve ever tried to set up an Intel RealSense camera with ROS 2 on a fresh machine, you already know the pattern: it works on one system, then breaks on another, and you lose time chasing environment differences. That’s why I put together realsense-ros2-docker — a small, focused repository that provides a simple Dockerfile for RealSense bring-up with ROS 2. Repo: https://github.com/SAJIB3489/r
State that survives a docker compose down is one of those things you don't think about, until your test suite needs it, your local dev needs it, and your CI pipeline absolutely doesn't. LocalStack handles persistence with one switch (PERSISTENCE=1) and it's a Pro-only feature. Floci ships four storage modes, all free, all in core, with per-service overrides. Pick the right tradeoff for the job.
