Following a report on Discord.
I'm struggling with the ddclient docker container because it doesn't has curl installed and my dyndns host needs it to update everything, what should I do to get it into your image? ❤️
here is an example what I have to enter to get it to run:
```
protocol=dyndns2
use=if, if=eth0
ssl=yes
use=cmd, cmd='curl https://checkipv4.dedyn.io/'
server=update.dedyn.io
login=XXXX.dedyn.io
password='XXXX'
XXXX.dedyn.io
```
That is what the log says to me:
```
Can't exec "curl": No such file or directory at /usr/bin/ddclient line 2175.
WARNING: found neither ipv4 nor ipv6 address
```
