Chapter 14: Understanding the Linkerd Service Mesh

1. True – Linkerd has an automatic protocol and TCP connection detection.
2. False – Linkerd does not provide its own ingress controller.
3. False – The Linkerd proxy is written in Rust, while control plane components are written in Go.
4. True – The control and data planes can be in a single namespace if we want them to be. Note that admin privileges are required to create CRDs.
5. True – When a Linkerd proxy is injected into a running pod using the linkerd inject command, the pod is restarted automatically.
6. False – The pod will be recreated if we want to add a debug sidecar.
7. True – The retry budget helps us avoid a retry storm. We don't need to configure Linkerd to achieve this.
8. True – For automatic sidecar injection, Istio needs a namespace to be labeled with istio-injection=enabled...
