By themselves, simple routed networks or the commonly used flannel network driver, for example, cannot apply network policy.
So will Flannel support network policy? Then when?
@SydOps You can get network policies with flannel today if you use Canal!
Check it out - https://github.com/tigera/canal
It runs Calico alongside Flannel for network policy.
@caseydavenport
Thanks, will take a look.
So why should I use flannel at all rather than calico?
