Perfect explination with hand drawn schema.

Great talk. Network Policies are definitely being underutilized. Thanks for clarifying all that.

[@phannguyen1556]

@Cristiano Brayden i really appreciate your reply. I got to the site on google and im waiting for the hacking stuff atm. Takes quite some time so I will reply here later when my account password hopefully is recovered.

It's a useful tool indeed, but I profoundly disagree with logic that's being used in writing rules. Empty should mean Empty. An empty bracket ( [ ] ) should mean NO node! If ALL nodes want to be specified than a symbol like '*' (wildcard) should be used. The set could be read as [ * ]. That's the way it has always been and I don't see any reasons why we should stray from that true and tested historic symbolic protocol. Allowing the reverse of logic, where empty bracket means 'all nodes' can be the source of costly errors in big projects.

[@matthartstonge]

Had a quick think about this, I compare it to NoSQL(mongo) and RESTful APIs, where if you specify nothing to filter by, you get all the things!

[@yahyabilge9765]

Some little confusion about cdir vs cidr :) But gorgeous explanation and presentation

[@dsinghr]

Isn't RBAC does the same thing? It allows specific microservices to talk to specific microservices. Similar to what NetworkPolicies does..

[@Aliennnaa]

network policies usually works on layer 4 or 3 of osi ,where is rbac are at the endpoint talking to the api server to get authorization so layer 7

[@TiexinGuo]

I wouldn’t listen to a guy talking about network who reads CIDR as CDIR multiple times.

[@zamboz01]

Yeaa like he is doing it on purpose not because there are hundreds of people in front of him. He miss spoke a few times but it is normal in that setting. But you will never know.
