Original stackfile

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

services:
  kratos-selfservice-ui-node:
    ports:
      - "4455:4455"
    environment:
      - PORT=4455
      - SECURITY_MODE=
      - KRATOS_BROWSER_URL=http://127.0.0.1:4433/

Or deploy it directly from the source:

git clone https://github.com/xneo1/portainer_templates
cd portainer_templates
docker compose -f Template/Stack/ory-kratos-standalone.yml up -d

More install options in our documentation.

Serve Ory Kratos (Standalone) 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 ory-kratos-standalone.example.com to http://kratos-selfservice-ui-node:4455

Add this to your Caddyfile

ory-kratos-standalone.example.com {
	reverse_proxy http://kratos-selfservice-ui-node:4455
}

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 0.0.0.0:4455 failed: port is already allocated", something else on your server is using that port.

  • Find what's using it: sudo ss -tlnp | grep :4455
  • Stop the other service, or pick a different host port. In 4455:4455 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:4455. The 0.0.0.0 link Portainer shows isn't a real address.
  • Give it a minute after first deploy, kratos-selfservice-ui-node can take a while to initialise.
  • Make sure your firewall allows the port, e.g. sudo ufw allow 4455

Required settings are blank

SECURITY_MODE has no default value, and kratos-selfservice-ui-node may crash or misbehave if left empty.

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

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

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

Ports

A port is the door the app answers on. A mapping like 4455:4455 means it's reachable on port 4455 of your server, where the left number is yours to change and the right one belongs to the app. It opens:

  • 4455:4455

Environment variables

Environment variables are the settings you hand over when you deploy, things like a password or a timezone. Ory Kratos (Standalone) takes 3 of them, and one needs a value before it'll start properly:

  • PORT, defaults to 4455
  • SECURITY_MODE, needs a value
  • KRATOS_BROWSER_URL, defaults to http://127.0.0.1:4433/

Networking

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

Container name

Once it's deployed, Portainer names the container kratos-selfservice-ui-node. That's what you'll spot in the containers list and use in commands like docker logs kratos-selfservice-ui-node.

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 Ory Kratos (Standalone) up. Add the template list to Portainer once, then deploying Ory Kratos (Standalone) is a click rather than a wall of config.
