Kubernetes Network Policies Using Cilium - Controlling Ingress/Egress from Namespaces
Kubernetes clusters are used by multiple tenants to run their containerized workloads. Often, the tenant workloads are mapped to namespaces and strict access control is required for inter-namespace communications. The access control could be needed for separation of concerns such as monitoring namespace vs application namespace; for compliance such as PCI vs non-PCI workloads; or to meet requirements of serving different end customers such as workloads serving Pepsi vs Coke. In this post, we will look at namespace based segmentation of traffic along with examples of allowing specific inter-namespace communications.

Cilium 1.2: DNS Security Policies, EKS Support, ClusterMesh, kube-router integration, ...
We are excited to announce the Cilium 1.2 release. The release introduces several new features addressing the top asks from Cilium users and community members. One of the most exciting features is the introduction of security policies based on DNS names to secure access to external services outside of the cluster. Another top ask was to introduce the ability to connect and secure multiple Kubernetes clusters. We are introducing ClusterMesh as an alpha level feature to address this ask. It allows to connect and secure pods running in different Kubernetes clusters. Equally important is the Kube-router integration with Cilium. The effort led by the team from DigitalOcean enables to combine BGP networking provided by kube-router with BPF based security and load-balancing from Cilium. As usual, a big shout out to the entire community of Cilium developers. The total number of contributors has grown to 85 and 579 commits have been contributed in the time period between 1.1 and 1.2.

Prometheus Metrics for Kubernetes Networking Using Cilium
In Kubernetes deployments, Prometheus is a popular monitoring system and time-series database for storing health and performance metrics of all the components. Equally popular is Grafana for plotting the metrics. In this post, we will provide steps to setup Prometheus and Grafana for understanding important Cilium metrics related to the security and health of service interactions in a Kubernetes cluster.
