Or, use the original compose file, straight from the template repo. Deploy with:
git clone https://github.com/lissy93/portainer-templates
cd portainer-templates
docker compose -f sources/stacks/systemprompt.yml up -dFor more installation options, see the Documentation in our GitHub repo
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:
137means killed, usually out of memory.126or127means 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 loginto 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
noso 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.
