Rules section. This guide assumes your external workload manages domain name resolution service via systemd. Prepare your cluster Enable support for external workloads Note First, make sure you have Helm cilium/cilium:v1.9.18 sudo cp /etc/resolv.conf /etc/resolv.conf.orig sudo systemctl disable systemd-resolved.service sudo service systemd-resolved stop Then, assuming they are in the same directory: NodePort CLUSTER_ADDR= configuration: sudo cp /etc/resolv.conf.orig /etc/resolv.conf sudo systemctl enable systemd-resolved.service sudo service systemd-resolved start Conclusion With the above we have enabled policy-based communication
