Container Documentation
monica-app Documentation
Monica – the Personal Relationship Manager.
monica-db Documentation
MySQL is a widely used, open-source relational database management system (RDBMS).
Serve Monica 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 monica.example.com to http://monica-app:80
Add this to your Caddyfile
monica.example.com {
reverse_proxy http://monica-app:80
}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.
Port already in use
If deployment fails with "Bind for 0.0.0.0:818 failed: port is already allocated", something else on your server is using that port.
- Find what's using it:
sudo ss -tlnp | grep :818 - Stop the other service, or pick a different host port. In
818:80only the left number is yours to change, the right one belongs to the app.
Running but the page won't load
The container is up but nothing appears in your browser.
- Use your server's real IP:
http://your-server-ip:818. The 0.0.0.0 link Portainer shows isn't a real address. - Give it a minute after first deploy, monica can take a while to initialise.
- Make sure your firewall allows the port, e.g.
sudo ufw allow 818
Permission denied on volumes
If the logs show "permission denied", the app can't write to its data folder on the host.
- Fix the ownership:
sudo chown -R 1000:1000 /portainer/Files/AppData/Config/monica(and the same for the other mapped folders)
Image won't pull
Test the pull directly on the host: docker pull monica:apache
- "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 always 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.

A Compose stack
Monica 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:
monica-apprunsmonica:apache, starts after monica-dbmonica-dbrunsmysql:5.7
Ports
A port is the door the app answers on. A mapping like 818:80 means it's reachable on port 818 of your server, where the left number is yours to change and the right one belongs to the app. Once it's running, open http://your-server-ip:818 in a browser. It opens:
818:80, likely the web interface
Volumes
A volume is where Monica 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/www/html/storagefrom/portainer/Files/AppData/Config/monicaon the host/var/lib/mysqlfrom/portainer/Files/AppData/Config/monica/mysqlon the host
Environment variables
Environment variables are the settings you hand over when you deploy, things like a password or a timezone. Monica takes 7 of them, all with defaults you can leave alone or tweak:
DB_HOST, defaults todbDB_USERNAME, defaults tomonicaDB_PASSWORD, defaults tosecretMYSQL_RANDOM_ROOT_PASSWORD, defaults totrueMYSQL_DATABASE, defaults tomonicaMYSQL_USER, defaults tomonicaMYSQL_PASSWORD, defaults tosecret
Restart policy
The restart policy here is always, so Docker brings Monica back up after a crash and again when the server reboots. Good for anything you want running around the clock. 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 monica-app) 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 Monica up. Add the template list to Portainer once, then deploying Monica is a click rather than a wall of config.
