I've to connect to a service running inside a runc container, I've written the below script and is able to ping the container from the host and can connect to the internet from inside the container.
But I'm unable to ping the container from another host.
bridge_setup.sh
#!/bin/bash sudo brctl addbr br0 sudo ip addr add 192.1xx.xxx.xx/24 dev br0 sudo ip link set br0 up net_setup.sh
