Install on Portainer

Import all app templates into your Portainer instance, for easy 1-click deploys

  1. Ensure both Docker and Portainer are installed, and up-to-date
  2. Log into your Portainer web UI
  3. Under Settings → App Templates, paste the below URL
  4. Head to Home → App Templates, and the list of apps will show up
  5. Select IronFunctions UI, fill in any config options, and hit Deploy

User interface for the open source serverless project at http://github.com/iron-io/functions

Serve IronFunctions UI on your own domain behind Caddy, Nginx or Traefik. Fill in your domain and copy the result. It's a starting point, some apps need their own base URL or extra headers set too.

Proxying ironfunctions-ui.example.com to http://ironfunctions-ui:4000

Add this to your Caddyfile

ironfunctions-ui.example.com {
	reverse_proxy http://ironfunctions-ui:4000
}

Check the logs first

Nine times out of ten the logs tell you exactly what went wrong.

  • In Portainer, go to Containers, click the container, then Logs. Or run docker logs <container>
  • Exit codes help too: 137 means killed, usually out of memory. 126 or 127 means the command inside the image is broken.

Published on a random port

This template exposes 4000/tcp without setting a host port, so Docker picks a random free one on every deploy.

  • Find it in the Ports column of Portainer's container list, or with docker port <container>

Image won't pull

Test the pull directly on the host: docker pull iron/functions-ui:latest

  • "manifest unknown" means the tag no longer exists. This template uses latest, so try pinning a specific version instead.
  • "toomanyrequests" is the Docker Hub rate limit. Log in with docker login to raise it.
  • "no space left on device" means a full disk. Reclaim space with docker system prune

"exec format error"

This means the image was built for a different CPU architecture than your server.

  • This image supports: amd64
  • Check yours with uname -m: x86_64 is amd64, aarch64 is arm64. Raspberry Pi and other ARM boards are the usual culprits.

Required settings are blank

API_URL has no default value, and the app may crash or misbehave if left empty.

  • Fill it in on the deploy screen before hitting deploy.

Privileged mode

This template runs the container in privileged mode, giving it full access to your host.

  • Only deploy it if you trust the app.
  • If deployment is blocked, your Portainer security settings or hardened host may not allow privileged containers.

Raise an issue

Found something which isn't working as it should? Here's how to report it.

A single container

IronFunctions UI runs as one container, the simplest kind of app here. Just the one image to pull and nothing else wired up alongside it.

The app image

An image is the app packed up ready to go, everything IronFunctions UI needs bundled into one download. This template pulls iron/functions-ui:latest, which Docker fetches once (about 77 MB) and then starts your own copy from.

Where the image comes from

Docker pulls its images from registries, public libraries of ready-built apps. IronFunctions UI's comes from Docker Hub, published by iron.

Version tags

The bit after the colon in the image name is the version tag. Here it's latest, which always points at the newest build, so a redeploy can bump you to a newer release without you asking. Newest right now is 0.0.5. Pin a specific tag if you would rather stay on one version.

Which machines it runs on

Every image is built for particular CPU types. This one ships for amd64, so it runs on regular x86 PCs and servers, though not ARM boards like a Raspberry Pi.

Ports

A port is the door the app answers on. Here the app exposes a port but leaves the host side blank, so Docker picks a free one for you. It opens:

  • 4000, published on a random host port

Volumes

A volume is where IronFunctions UI keeps its files so they survive an update or a restart. Without one, anything it saves would sit inside the container and vanish the moment it's recreated. This template mounts:

  • /app/data as a volume Docker manages for you

Environment variables

Environment variables are the settings you hand over when you deploy, things like a password or a timezone. IronFunctions UI takes 1 of them, and one needs a value before it'll start properly:

  • API_URL, needs a value. API URL

Networking

Nothing custom is set, so IronFunctions UI sits on Docker's default bridge network: its own private space that reaches the outside world only through the ports it publishes.

Privileged mode

This template runs IronFunctions UI in privileged mode, which gives it nearly as much access to your server as the system itself. Some apps genuinely need it to reach hardware or manage the host, so it's one to run only if you trust the source.

Platform

The platform is linux, the kind of system the container is built to run on. Docker and Portainer handle this on a normal Linux server.

Portainer app templates

Zooming out, this whole page comes from a Portainer app template: a short recipe telling Portainer how to set IronFunctions UI up. Add the template list to Portainer once, then deploying IronFunctions UI is a click rather than a wall of config.
