Docker had internet connection problems

It was solved like this:

1. Create a daemon.json file to add the dns that your machine uses and the google dns that docker uses like this:

{
"dns": ["1.1.1.1", "8.8.8.8"]
}

2. The file /etc/resolvf.conf has a symbolic link that is directed to a default file in ubuntu that contains an ip like 127.0.0.53

we have to make the link like this: ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf which is really the dns used by the network.

3. It will force Docker to recreate the bridge and reset all network rules.

with this script:
pkill docker
iptables -t nat -F
ifconfig docker0 down
brctl delbr docker0
docker -d

4. Restart docker service

service docker restart

5. Clear all docker install error cache with this command:

docker system prune

6. Run the docker installation again

$ docker-compose build --build-arg TARGETARCH=amd64
$ docker-compose up

Go to https://127.0.0.1/
Login with any of users created admin/P3t3r3p0rt (administrator) and viewer/v13w3r (viewer) or the user credentials configured in the configuration file
