Sorry for the question but I can't get the image to work.
It seems that mounting the volumes does not work.
Both with docker-compose and docker-run I get the error.

ERROR: for ddns Cannot start service ddns: failed to create shim: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:545: container init caused: rootfs_linux.go:76: mounting "/home/docker/ddns/database" to rootfs at "/root/dyndns/database" caused: mount through procfd: open o_path procfd: open /var/lib/docker/overlay2/ef39d03481702de8c0a78268fdbc289a44817d9a0c1bb2ec4f50c381a3b382ee/merged/root/dyndns/database: not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

by adding value to the environment or any other way? please help

In my opinion, the logs page currently has no advantage because only the first 30 logs are listed and I cannot see the last updates.
The best solution is probably paging, but I think it's an advantage if you can see the "last" 30 logs.

Hi, I am trying to migrate from MintDNS on Windows Server 2012 to this awesome replacement, but I am running into a few issues:

1. When I try to create a hostname with just a single character (such as a.example.com, I get the following error:

   Error: Key: 'Host.Hostname' Error:Field validation for 'Hostname' failed on the 'hostname' tag`

   Where can I edit and remove this restriction?

2. I was able to remove the 8-character minimum restrictions for usernames and passwords, but I was wondering, is it possible to not limit hostnames to unique usernames? I would like to be able to assign multiple hosts to the same user (that way current hosts assigned to the same user can continue to resolve without the login information needing to change.

3. How can I make both hostnames and usernames case INsensitive on creation, edit and ddns updates? I would like that regardless of how they are inputted (on creation of hostname and edits) or received for DDNS Update, that they are always translated to lowercase and stored that way.

Any help would be appreciated. Thanks in advance.

Hello, first of all, thank you very much, you made a really good project.
Excuse my lack of knowledge, I am trying to achieve something like dyndns.org is doing, i have this domain dyn.xyz, and i want that my host be like lottar.dyn.xyz -> 22.33.44.11

In my registrant I added this records

ddns.dyn.xyz. A 11.22.33.44
ns NS 11.22.33.44

this is my setup.

version: '3'
services:
ddns:
image: bbaerthlein/docker-ddns-server:latest
restart: always
environment:
DDNS_ADMIN_LOGIN: 'admin:$apr1VH1Az7CwF5qRV'
DDNS_DOMAINS: 'dyn.xzy'
DDNS_PARENT_NS: 'ns.dyn.xyz'
DDNS_DEFAULT_TTL: '3600'
ports:
- "53:53"
- "53:53/udp"
- "8080:8080"
volumes:
- ./bind-data:/var/cache/bind
- ./database:/root/database

Can you help me, I am stuck, not able to achieve it ..

Would it be possible to implement a field to enter the DNS type?
Such as an MX record
Thank you very much!!!, sorry for my English :)

Good day,

i would like to use Zone-Transfer and this docker-instance as primary dyndns zone, is that possible or could you implement it?

Would be neat that you could simply add a zone-transfer option with a list of allowed server ips over the GUI ;).

Following planed setup: Plesk as secondary dns server for the subdomain, your docker instance as primary with zone-transfer.

Thanks a lot.

Best Regards

Hi,
i've deployed the container and opened the 53 Port in my Firewall.

I've created an CNAME record on my Domain for ddns.domain.tld. This points to my nginx which is a reverse proxy with TLS offloading for the UI (:8080).
I can access the UI with the BASIC Auth credentials, and API Requests are working too.

I also added Following DNS Records:

The host was refreshed successfully via API (i see it in Logs and on UI)

my problem is:
When i enter https://host.myzone.domain.tld , i cannot reach my server. I am getting the following error:

Hmmm… can't reach this page

It looks like the webpage at https://host.myzone.domain.tld/ might be having issues, or it may have moved permanently to a new web address.
ERR_TUNNEL_CONNECTION_FAILED

I enabled Port Forwarding on my Router already. When entering https://Router-IP, I can access my Server behind it.

Somehow it seems, that the NS Record is not really propageted, because i cannot even ping my URL except using a custom DNS:

$ ping host.myzone.domain.tld

ping: host.myzone.domain.tld: Temporary failure in name resolution

$ nslookup host.myzone.domain.tld

Server:         127.0.0.53
Address:        127.0.0.53#53
 
** server can't find host.myzone.domain.tld: SERVFAIL
 
$ nslookup host.myzone.domain.tld myzone.domain.tld

nslookup: couldn't get address for 'myzone.domain.tld': failure

$ nslookup host.myzone.domain.tld mzns1.domain.tld

Server:         mzns1.domain.tld
Address:        123.123.123.123#53
 
Name:   host.myzone.domain.tld
Address: <router-ip>

It's been already 2 Days since i configured the DNS.
What am i doing wrong?

DynDNS not compatible API
pls help me .
how can update from router's API

/nic/update?hostname=blog.dyndns.example.com
Return : {"message":"Not Found"}

The handlers will listen on:
/nic/update
/v2/update
/v3/update

I run the following code:
docker run -it -d \ -p 4080:8080 \ -p 53:53 \ -p 53:53/udp \ -v /opt/ddns/bind:/var/cache/bind \ -v /opt/ddns/database:/root/database \ -e DDNS_ADMIN_LOGIN='******:$$apr1$$evkvf9PG$$q6yyhxZvWdtPN5Vmg1Mne/'\ -e DDNS_DOMAINS=dyndns.*****.de \ -e DDNS_PARENT_NS=dns1.*****.de \ -e DDNS_ALLOW_WILDCARD=true \ -e TZ=Europe/Berlin \ -e VIRTUAL_HOST=dyndns.olivertempel.de \ -e LETSENCRYPT_HOST=dyndns.olivertempel.de \ -e [email protected] \ -e DDNS_DEFAULT_TTL=3600 \ --network="proxy" \ --name=dyndns \ bbaerthlein/docker-ddns-server:latest

username and password where generated with:
echo $(htpasswd -nb user password) | sed -e s/\$/\$\$/g

If i want to login, it says authentication failed.

Whats Wrong?

Hi and thanks for this handy tool,

as i had a ddns service before i have some clients rolled out and want to
add them to the new service - the usernames and passwords were really short and i dont want
to change them on the clients - is there a way to disable the check for these fields (username / password)??

Currently i get the following warning:

Error: Key: 'Host.UserName' Error:Field validation for 'UserName' failed on the 'min' tag

Thanks in advance.

would be great to have multi arch containers (arm and arm64), its simple to setup with github actions for public repositories:

see https://github.com/maltegrosse/zero-ui-noauth/blob/main/.github/workflows/container.yml

First of all, big thx for the nice server. I'm currently trying it out on my VPS and found a few things which would be cool to get fixed.

If you add a host and update it with a ipv4 and a ipv6 address, both addresses are available on the DNS, but the hosts view only shows the last updated entry. It would be nice if it could show both entries.

Are they using this system whose interface is slightly different but very similar in terms of API and the data it receives?

https://www.duckdns.org/

i have the follwing configuration in my docker

version: '3'
services:
  ddns:
    image: bbaerthlein/docker-ddns-server:latest
    container_name: dyndns
    restart: unless-stopped
    environment:
      DDNS_ADMIN_LOGIN: 'example:example_pwd'
      DDNS_DOMAINS: 'ns.example.com'
      DDNS_PARENT_NS: 'ns.example.com'
      DDNS_DEFAULT_TTL: '3600'
    ports:
      - "53:53"
      - "53:53/udp"
      - "8080:8080"
    volumes:
       - ./bind-data:/var/cache/bind
       - ./database:/root/database
    networks:
       - proxy
       - dyndns
networks:
  dyndns:
  proxy:
    external: true 

The configuration works fine and is running. I also can update the IPs but i couldn't manage to get the answer when calling the host.

Configuration DNS Try 1:
1.) ns.example.com A IP-OF-NGINX-PROXY
2.) *.ns.example com CNAME ns.example.com

Not working (only for update)

Configuration DNS Try 1:
1.) ns.example.com A IP-OF-NGINX-PROXY
2.) *.ns.example com NS ns.example.com

Not working (only for update), if i try the host host1.ns.example.com i get "no dns-adress found. DNS_PROBE_POSSIBLE " when i look at the terminal of DDNS-Server there is also no request.

If i make a NS-Lookup at ns.example.com there are even no entries

So i am wondering if i have some misconfiguration of my NGINX Proxymanager.
Did anyone manage it to get it work?

In the docs it says to create a record for ns.<domain.tld> to point to "put ipv4 of dns server here". It is not clear to me if that means pointing to where the acme-compainion is running, as it functions as DNS as well (as far as I understand) or if it has to point to my provider DNS server.

Can somebody enlighten me?

I have some services running at home which don't work with ipv6 addresses (on the server side), but as my router is updating both addresses (and i cannot configure it there), the clients will always get the ipv6 address and fail to connect.

What i've noticed, is that when only the A entry of the DNS is set, the client resolves only the ipv4 address and the connection works fine. For those cases it would be great if there is a flag to prevent ipv6 entries of a certain host.

Hello, if ever you can provide information on how to deploy this container, with docker-compose, behind traefik, that would be incredible!

Also, is the webUI also on 8080 or is it on another port? because I can't reach it.

I understand that this is against the way of a ddns service and you don't update those entries, but for providing aliases to other dyndns entries e.g. when you changed the name, this can be really useful.

Hi!

My router is only able to issue one GET-query with placeholders for the IPv4 and IPv6 address to update a dDNS provider.

So I wanted to propose adding query-parameters to trigger updates of both the A and AAAA record from one query. From a quick look it seems this would need some additional mechanics in the UpdateIp function. I'd propose adding the type-explicite parameters myipv4 and myipv6 while keeping myip with automatic type determination around for backwards compatibility.

Cheers,

Jörn

My ddns domain has a single letter component. Like this for example:
myhost.d.example.com

The ".d." fails the validation tag "hostname" of github.com/go-playground/validator.
Afaik there is no reason that the domain should be validated as a hostname. It should rather be the fqdn validator tag.

disable auth would be a nice feature in order to plugin some oauth proxy in front of the ui.

perhaps some minor changes have to be done:
either here:
https://github.com/benjaminbear/docker-ddns-server/blob/master/dyndns/handler/handler.go#L69
something like os.Getenv("DDNS_ADMIN_DISABLE") --> return true

or here:
https://github.com/benjaminbear/docker-ddns-server/blob/master/dyndns/handler/handler.go#L90
just allow empty admin env variable (not sure how it behause in the auth process if ein empty string is set....)

PS. moving all admin routes in an admin subfolder would make to regex matching easier for the oauth proxy, something like ./admin/. and redirect all ./ to ./admin/
