Transparent Proxy on Consul Service Mesh

Consul 1.10 can transparently intercept and redirect traffic to sidecar proxies in the service mesh to allow applications to be deployed without modification. Transparent proxy, a new feature in Consul 1.10, provides an easier onboarding experience for deploying applications with Consul service mesh on Kubernetes. With transparent proxy, traffic is automatically redirected from a service within the application to the service's sidecar proxy.

Using transparent proxy in conjunction with terminating gateways and service intentions, traffic can also be forced to egress through terminating gateways, ensuring to secure communication with services outside the network.

One example of utilizing transparent proxy with traffic redirection exemption involves deploying ingress controllers on Kubernetes and using sidecars to facilitate direct communication with a service mesh.
