+# ownDynDNS-netcup
+
+![docker-build](https://github.com/sujiba/ownDynDNS-netcup/actions/workflows/docker_build_push.yml/badge.svg?event=push)
+
+
+This container is based on the work of:
+* [PHP](https://hub.docker.com/_/php)
+* [Fernwerker ownDynDNS](https://github.com/fernwerker/ownDynDNS)
+
+## Nectup configuration
+You need to create your dns entries beforehand:
+
+| Host     | Type  | Destination  |
+|----------|-------|--------------|
+| vpn      | AAAA  | IPv6         |
+| vpn      | A     | IPv4         |
+
+## Container configuration
+Create docker-compose.yml and config in your app directory i.e.:
+
+```
+mkdir -p /opt/docker/owndyndns
+cd /opt/docker/owndyndns
+
+# Create docker-compose.yml and copy the contents from repository file
+vi docker-compose.yml
+
+# Create config, copy the contents from repository file and change the parameters
+vi config
+
+# Start the Container with
+docker compose up -d
+```
+
+## Fritz!Box configuration
+* Login to your Fritz!Box
+* Go to /Internet/Freigabe/DynDNS
+* Set mark on "DynDNS benutzen"
+* Enter Update-URL: `https://<url of your webspace>/update.php?user=<username>&password=<pass>&ipv4=<ipaddr>&ipv6=<ip6addr>&domain=<domain>`
+    * You only have to change `https://<url of your webspace>` (http without valid TLS certificate)
+* Domainname: `vpn.example.com`
+* Username: Defined in config 
+* Password: Defined in config
