Kubernetes network policies: Both the Azure Network Policies and Calico work with this new solution.Deploy on: Calico supports multiple data planes: Even if an app scales to thousands of containers in seconds, Project Calico can still configure security seamlessly. firewalld provides an init script for systems using classic SysVinit and also a systemd service file. EKS, AKS, GKE, VMware Tanzu, Rancher, Openshift, Kubeadm. A lot of time has passed since then, and Kubernetes networking has continued to mature, with many of Calico’s core concepts now adopted as mainstream Enable and Disable firewalld. 11, which was the current version at that time. I do not feel sure calico is a cause of this problem. kube-system calico-node-ct6c9 2/2 Running.

I've bringing up Kubernetes cluster with calico as CNI on CentOS 7 with firewall enabled.

ACI & Kubernetes – The Calico K8s CNI & MetalLB (Part One) 25th October 2021.

As lwr20 explained it already, both kubelet/calico and firewalld configured iptables.

To improve security, you can use Azure Network Policies or Calico Network Policies to define rules that control the traffic flow between different microservices. Calico firewalld In contrast to the Cisco ACI CNI ( read about this here ), the Calico CNI does not integrate with ACI but this is certainly not a negative, Calico and MetalLB have a lot to offer and to emulate some of the good parts of the Cisco Good point.
