Hello,
if i try to resolve a DNS with 8.8.8.8 for example from inside a Docker container i get the error
11:45:43 dcef1022a64a:/# dig @8.8.8.8 google.de
communications error to 8.8.8.8#53: host unreachable
communications error to 8.8.8.8#53: host unreachable
communications error to 8.8.8.8#53: host unreachable
The Docker container was setup with Portainer. Portainer was installed via TrueNas App.
Right now i use Jailmaker (jlmkr) and have a Pi-Hole container running as my local DNS.
From inside the Test Docker container DNS resolve with my local works fine (see screenshot). I use the rtsp/net-tools docker image as testing container.
If i go into a Docker container which are in a jlmkr container i am able to dig @8.8.8.8 google.de
vb are from the jlmkr linux container.
