Install HotLoop
There are two ways to run a HotLoop product for real: Helm on k3s or any Kubernetes, or Podman with Quadlet on a box that isn’t in a cluster. No Docker, no Compose, and no bare podman run from a shell that dies with the session. A plain podman run is fine to kick the tires, and Flow’s page says so, but it isn’t an install.
Pick the way
Section titled “Pick the way”| You have | Use | Page |
|---|---|---|
| A k3s or Kubernetes cluster | Helm | k3s and Helm |
| A Pi, a NUC or a small industrial PC, no cluster | Podman Quadlet | Podman Quadlet |
| Either, and you want to know how updates behave | The :stable auto-update |
What you can install today
Section titled “What you can install today”| Product | Latest release | Helm | Quadlet | Start here |
|---|---|---|---|---|
| HotLoop IoT | 4.18.10 | Yes | Yes | Install IoT |
| HotLoop Edge | 4.18.10 | Yes | Yes | Install Edge |
| HotLoop Gateway | 4.18.10 | Yes | Yes | Install the Gateway |
| HotLoop Edge Relay | 4.18.10 | Yes | Yes | Install the Edge Relay |
| HotLoop Flow | 2.2.0 | Yes | Yes | Install Flow |
| HotLoop Cascade | 0.1.2 | Yes, no login needed | Yes, no login needed, see Cascade with Podman Quadlet | Running Cascade |
HotLoop IoT, Edge, Gateway and the Edge Relay come out of one tag, in lockstep, so they share a version number. Flow and Cascade have their own. The IoT, Edge and Gateway Quadlet units need Podman 5.0 or newer, and the relay’s unit was run on Podman 4.9.3. Raspberry Pi OS Bookworm ships 4.3, which has no Quadlet at all, so a Pi wants Trixie or newer.
Before you put one on a real plant
Section titled “Before you put one on a real plant”- Read the write gate. It is the same in every product, and it’s why nothing moves a machine you didn’t arm.
- Put the database on a USB SSD and not the SD card, if it’s a Pi. History writes all day, every day, and SD cards die of exactly that.
- Back up the device password key. It isn’t in the database and it isn’t in a backup, so it is part of your data. Backups says how.
- Take a backup before you move a site up a product or upgrade across a release, and copy it off the box.
