Notes

Set at least one AI provider key or the gateway will not boot. First boot runs migrations and a publish pipeline; allow several minutes before the healthcheck passes. Optionally set EXTERNAL_URL to the public URL you will serve it on.

Original stackfile

The compose file this template deploys, straight from its repo:

# Canonical one-click catalog compose for the systemprompt gateway.
# This is the artifact marketplace catalogs (Portainer, Dokploy, CasaOS,
# CapRover derivatives) reference by raw URL. It runs the published GHCR
# image; the root docker-compose.yml builds from source. Keep the service
# and volume topology in sync — smoke-tests.yml `compose-drift` enforces it.

git clone https://github.com/lissy93/portainer-templates
cd portainer-templates
docker compose -f sources/stacks/systemprompt.yml up -d

Container Documentation

postgres Documentation

The PostgreSQL object-relational database system provides reliability and data integrity.

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.

Image won't pull

Test the pull directly on the host: docker pull postgres:18-alpine

  • "manifest unknown" means the tag no longer exists.
  • "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.

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

Container keeps restarting

The unless-stopped restart policy relaunches the app after every crash, so the real error can scroll past.

  • Check the logs right after a restart, the last few lines before it died are the useful ones.
  • Get the exit code with docker inspect <container> --format '{{.State.ExitCode}}'
  • Still stuck? Redeploy once with the restart policy set to no so the failure stays visible.

Stack won't deploy

Compose stacks fail fast on small mistakes, and Portainer shows the reason just above the editor.

  • YAML only accepts spaces for indentation, a single tab breaks the whole file.

Raise an issue

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

A Compose stack

systemprompt is a Compose stack, a set of containers (2 of them) defined in one file and brought up together by Portainer, then started and stopped as a single app.

The services

This stack is built from 2 containers that run side by side. Here's each one, with the image it runs and anything it waits for first:

  • postgres runs postgres:18-alpine
  • app runs ghcr.io/systempromptio/systemprompt-template:0, starts after postgres

Volumes

A volume is where systemprompt 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:

  • /var/lib/postgresql kept in the postgres_data volume Docker manages
  • /app/web kept in the app_web volume Docker manages
  • /app/storage/data kept in the app_storage_data volume Docker manages
  • /app/services/profiles/docker kept in the app_profiles volume Docker manages

Environment variables

Environment variables are the settings you hand over when you deploy, things like a password or a timezone. systemprompt takes 10 of them, all with defaults you can leave alone or tweak:

  • POSTGRES_USER, defaults to systemprompt
  • POSTGRES_PASSWORD, defaults to systemprompt
  • POSTGRES_DB, defaults to systemprompt
  • DATABASE_URL, defaults to postgres://systemprompt:systemprompt@postgres:5432/systemprompt
  • ANTHROPIC_API_KEY, pulled from your own environment
  • OPENAI_API_KEY, pulled from your own environment
  • GEMINI_API_KEY, pulled from your own environment
  • EXTERNAL_URL, pulled from your own environment
  • HOST, defaults to 0.0.0.0
  • PORT, defaults to 8080

Restart policy

The restart policy here is unless-stopped, so Docker restarts systemprompt after a crash or reboot, but leaves it off when you stop it on purpose. You can change this on the deploy screen. The choices are no (never restart), on-failure (only after a crash), unless-stopped (restart unless you stop it), and always (bring it back no matter what).

Networking

Portainer puts these services on one shared private network, so they can find each other by name (like postgres) while only the ports above are open to you.

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 systemprompt up. Add the template list to Portainer once, then deploying systemprompt is a click rather than a wall of config.
