docker ubuntu networking bash

I've been banging my head against this for hours. I've been banging my head against this for hours... I'm working with an scenario with Docker on Ubuntu 22.04 where my containers want to access the external internet. My Docker setup uses the default bridge network, and I have verified that the host can access the internet without any issues. However, when I try to ping external addresses from within a container, I get `ping: bad address 'google.com'`. I have tried restarting Docker and flushing the iptables rules, but the question continues. Here's how my Docker network is configured: ```bash $ docker network ls NETWORK ID NAME DRIVER SCOPE 3e71054ce9d2 bridge bridge local 0a1b2c3d4e5f host host local 6f3e7d8a9b0c none null local ``` I also checked the container’s DNS settings and they appear to be fine: ```bash docker run --rm --network bridge busybox cat /etc/resolv.conf ``` This outputs: ``` # Generated by resolvconf nameserver 127.0.0.11 options ndots:0 ``` I’ve confirmed that the Docker service is running with: ```bash $ systemctl status docker ``` The output shows the service is active. Additionally, I ran: ```bash docker run --rm --network bridge busybox ping 8.8.8.8 ``` This fails with `ping: 8.8.8.8: Network is unreachable`. Is there something I might be missing in the configuration, or is there a deeper networking scenario I should investigate? Any insights would be greatly appreciated! My development environment is Linux. Any help would be greatly appreciated! This is part of a larger application I'm building. Thanks in advance!
