Connecting network namespace to internet via Linux bridge
I am running a Ubuntu 16.04 host. I have 3 network namespaces: ns1,ns2 and ns3.
# ip netns add ns1
# ip netns add ns2
# ip netns add ns3
I also created a Linux bridge using brctl called testbr.
Using 3 veth pairs, I connected the three network namespaces to the linux bridge (each pair has one end attached to a network namespace and other end attached to the bridge.
ns1 (veth11) --- (veth12) testbr
ns2 (veth22) --- (veth22) testbr
ns2 (veth32) --- (veth32) testbr
I also assigned them IP addresses.
ns1 (veth11: 10.0.0.1) --- (veth12) testbr
ns2 (veth22: 10.0.0.2) --- (veth22) testbr
ns2 (veth32: 10.0.0.3) --- (veth32) testbr
With this setup I am able to ping ns2 or ns3 from ns1. The following works:
# ip netns exec ns1 ping 10.0.0.2
I want to able to ping IPs outside my host from one of the network namespace. For the example, the following should work:
# ip netns exec ns1 ping 8.8.8.8
I want to ask how can I connect my containers (network namespaces) to the internet via the bridge I have setup.
