Linkerd Service Mesh

The Linkerd Service Mesh is installed in all Kubernetes clusters at Gjensidige. Linkerd's main function is to ensure encrypted network traffic inside the cluster. This is achieved by injecting a Proxy Sidecar into all pods. All inbound and outbound network traffic to pods will then be routed through these proxies, which in turn secures the communication using Mutual TLS Authentication (mTLS).
