TLDR: Describe your issue in a one liner here

I've set up the config.json several times and it wont update when I check the webui.

I recently rebuilt a corrupt docker.img and it was working perfectly before.

  1. Is this urgent: No

  2. DNS provider(s) you use: Cloudflare

  3. Program version:

    Running version latest built on 2020-03-13T01:30:06Z (commit d0f678c)

  4. What are you using to run the container: unraid

  5. Extra information (optional)

Logs:

Running version latest built on 2024-02-04T14:45:13.409Z (commit 133956f)

Check the config.json file is bind mounted correctly? It seems it doesn't find it (so it creates it as empty)

It created an empty file which I later filled. How do I verify if bind is mounted? I followed each step.

Where is your config.json file on your host system, and what's your bind mount configured for the /updater/data directory?

/mnt/user/appdata/ddns-updater/data I don’t follow on bind mount - is that the “touch” command? I followed each line from the unraid instructions exactly.

You should a volume mount (aka bind mount) between /mnt/user/appdata/ddns-updater/data (on your host system) and /updater/data (in the container)

Correct. That’s how mine is setup. /updater/data in the container and /mnt/user/appdata/ddns-updater/data is where config is stored.

Try running it with LOG_LEVEL=debug and see what logs it has? It should log out the entire configuration read, I guess in this case likely just {}?

Yes it doesn't find the file /updater/data/config.json.

DEBUG config read: {}

so it creates as an empty json object {}.

Try accessing a terminal on your Unraid machine and run

docker inspect --format "{{json .Mounts}}" $(docker ps --filter "label=org.opencontainers.image.title=ddns-updater" --latest --format "{{.ID}}" --no-trunc)

That should print out the bind mounts
