Container Documentation

blinko-postgres Documentation

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

Serve Blinko 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 blinko.example.com to http://blinko-website:1111

Add this to your Caddyfile

blinko.example.com {
	reverse_proxy http://blinko-website:1111
}

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.

Port already in use

If deployment fails with "Bind for 0.0.0.0:1111 failed: port is already allocated", something else on your server is using that port.

  • Find what's using it: sudo ss -tlnp | grep :1111
  • Stop the other service, or pick a different host port. In 1111:1111 only 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:1111. The 0.0.0.0 link Portainer shows isn't a real address.
  • Give it a minute after first deploy, blinko can take a while to initialise.
  • Make sure your firewall allows the port, e.g. sudo ufw allow 1111

Image won't pull

Test the pull directly on the host: docker pull postgres:14

  • "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 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 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

Blinko 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:

  • blinko-website, starts after blinko-postgres
  • blinko-postgres runs postgres:14

Ports

A port is the door the app answers on. A mapping like 1111:1111 means it's reachable on port 1111 of your server, where the left number is yours to change and the right one belongs to the app. It opens:

  • 1111:1111
  • 5432:5432

Environment variables

Environment variables are the settings you hand over when you deploy, things like a password or a timezone. Blinko takes 8 of them, all with defaults you can leave alone or tweak:

  • NODE_ENV, defaults to production
  • NEXTAUTH_URL, defaults to http://localhost:1111
  • NEXT_PUBLIC_BASE_URL, defaults to http://localhost:1111
  • NEXTAUTH_SECRET, defaults to my_ultra_secure_nextauth_secret
  • DATABASE_URL, defaults to postgresql://postgres:mysecretpassword@postgres:5432/postgres
  • POSTGRES_DB, defaults to postgres
  • POSTGRES_USER, defaults to postgres
  • POSTGRES_PASSWORD, defaults to mysecretpassword

Restart policy

The restart policy here is always, so Docker brings Blinko 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 blinko-website) 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 Blinko up. Add the template list to Portainer once, then deploying Blinko is a click rather than a wall of config.
