Can anyone tell me what's wrong with this stack? All I get is a white page when trying to visit the web ui:

version: "3.8"

services:

    shlink:
        hostname: shlink
        image: shlinkio/shlink:latest
        environment:
            TZ: ${TZ}
            PUID: 1000
            PGID: 1000
            DEFAULT_DOMAIN: 'shlink.mydomain.com'
            IS_HTTPS_ENABLED: 'true'
            GEOLITE_LICENSE_KEY: 'redacted'
            DB_DRIVER: 'mysql'
            DB_HOST: 'mysql'
            DB_USER: 'shlink'
            DB_PASSWORD: 'redacted'
        networks:
            - odb
        deploy:
          mode: replicated
          replicas: 1
          placement:
            constraints:
              - node.labels.Main == true
          restart_policy:
            condition: any
 
    shlink-web-client:
        hostname: shlink-web-client
        image: shlinkio/shlink-web-client:latest
        environment:
            TZ: ${TZ}
            PUID: 1000
            PGID: 1000
        depends_on:
            - shlink
        ports:
            - 8990:80
        networks:
            - odb
        deploy:
          mode: replicated
          replicas: 1
          placement:
            constraints:
              - node.labels.Main== true
          restart_policy:
            condition: any

networks:
  odb:
    external: true
    name: db

It's connecting and filling the db, so the db connection isn't the issue.

TIA

The first thing I would suggest is that you don't use the latest tags. Those are considered unstable. Try with a specific version. https://shlink.io/documentation/install-docker-image/#versions

If that doesn't help, open the browser console and check the output.

Finally, you can also check the web client container logs.

@acelaya ty. Ok, ill take a look and report back my result.

Side note, any chance of making a single image that includes both the back end and the web ui, so we don't have to 'stack' them, and just run 1 container? (I try to live by the "KISS" mantra ("Keep It Simple, Stupid")). lol

Shlink web UI is split by design.

Shlink web UI is split by design.

I know, but is there no way to join them in a single container still?

It is probably not easy, as it would break many of the containerized software principles. But even if it was, it is not going to happen, because it's a concious decison, and would make no sense because of how the web client is designed. You will understand it once the white screen issue is solved.

@acelaya Success! changing them both to :stable got me to a UI. :)

I think the tagging is what threw me. Usually people will use :latest for stable, and something like :nightly for the latest potentially unstable changes.

ty for the help!

I'm running into another issue now :/

Shlink container runs fine, and populates the MySQL db when it starts. Verified by dropping all tables in it and restarting the container. Several times.

Log:

<etc..> Many of those....

Shlink web UI container also seems to run fine, and I can load the page.

I can ping both the MySQL and web client containers from the shlink container:

I can ping the shlink and MySQL containers from the web ui container:

But when in the web ui it says "visits: NaN" and "orphan visits: shlink 2.6 is needed" (I have Stable 2.10 which I'm assuming is .4 versions backward compatible), and at the bottom it says "Server: - Client: v3.4.2" (no server version).

So it's like it's not connecting to the db somewhere. When I say "it", I don't know whether it's shlink or the webui container, since shlink seems to connect and populate, and the web ui seems to make zero connections to the db? (I'm assuming the web ui doesn't connect to the db since it requires reading the server info from a .json file and not the db?

No idea how to precede from here
