docker in unraid can't find expected key

Hi there, I'm trying to use your docker implementation in unraid and I'm receiving an error when I try to start it.

time="2021-06-27T03:39:09Z" level=fatal msg="yaml: line 33: did not find expected key"

It is definitely seeing the .yaml file. I've tried putting my public ip in the data: field to no avail.
I'm trying to add a subdomain home.domain.com

I have created an api key and put it in the ddns.yml file.

Any help would be appreciated, thanks!

Hi @wwray,

Could you please share how you setup a yaml file?

Try the following configuration:

domains:
  domain.com:
  - type: "A"
    name: "home"

Hi @wwray ,

Thanks!

But unfortunately, this is not the full yaml file. May I ask you to share full yaml file (without secrets, better via GitHub to preserve spacing and highlighting)?

In first message error says that error is on line 33. My assumption is that maybe some spacing is broken. I want to see what is on line 33 and around.

For an experiment you can replace your current file with the following configuration and see if it works:

token: "<your Digital Ocean token>"

domains:
  wraynet.com:
  - type: "A"
    name: "home"

Here you go! sorry I misunderstood, thanks again for your help.

when I use the config provided I get a different error

I've found the following issues:

  1. data key had space in front and this led to error on line 31
  2. because YAML is an interesting format and not JSON, lines with priority, port etc. will be parsed incorrectly (commas in the end of lines

I've adjusted the file (see attached) and seems like it's working now as expected.

I downloaded your file, and pasted in my token in but am still getting an error

Please check what you have on line 22

attached file. There's 3 spaces before the domain, thanks for helping out.

Ok so I finally got it to validate on a .yaml validator and I'm still having the unmarshal error on the 1st domain entry. I understand yaml a lot better than I did this morning. Pretty neat!

Happy to hear that!

What version of ddns are you using?

ddns -v in old one and ddns -ver in new one

wwray commented

I can't get it to start because of the error so can't tell ya. I am using this docker https://hub.docker.com/r/ronnieroller/ddns

skibish commented

Seems like you are using a fork :)

Try this one: https://hub.docker.com/r/skibish/ddns

wwray commented

My deepest apologies @skibish ! I didn't realize I was using a fork. I would have been very sad if it had just worked, but now I'm getting the error below when starting the docker using the config file I provided above.

Ok well, I can't get the container that I'm using to even register the existence of the .ddns.yml file. If I delete it I get the exact same error.
I loaded it up using docker run command in your help docs and I got:

Status: Downloaded newer image for skibish/ddns:latest time="2021-06-28T17:29:52Z" level=debug msg="using the following configuration file: /config/.ddns.yml" time="2021-06-28T17:29:52Z" level=debug msg="initializing ip" time="2021-06-28T17:29:53Z" level=info msg="current ip is <deleted>" time="2021-06-28T17:29:53Z" level=debug msg="syncing dns records" failed to sync dns records: failed to create a record for the domain wraynet.com: unexpected response with status code 422

Which is probably what is supposed to happen, but even if I get the container working I'll then have to deal with the DO error. I'm gonna sit on it and see if I want to try some other way. You can close this ticket since I suspect it's not a problem with your software, thanks for all your help!

Yep, it's a good sign that configuration file is valid and application was able to read it.

I think the issue is now that you specify multiple arrays which all are invalid.

    - 
      type: A
    - 
      name: home
    - 
      data: "{{.IP}}"
    - 
      ttl: "1800"

Each dash means a new array element and in the end they are all wrong because first one has only type: A which is not enough to create a record, second one a name: home which is also not enough because it waits for type, etc.

I should be like this:

domains:
  wraynet.com: 
    - type: A
      name: home
      data: "{{.IP}}"
      ttl: "1800"
