Diagram 13-1, 13-2 |
the 2 scenario diagrams in Chapter 13 about multi-cluster setup (13-1, 13-2) do not clearly illustrate the differences. And they may have been swapped
In 13-1: https://learning.oreilly.com/library/view/istio-up-and/9781492043775/assets/iuar_1301.png
1. there are numbered call-outs but not referenced anywhere in the chapter
2. the diagram included seems confusing as the text refers it to a single control plane but each cluster in the diagram shows its own control plane. If it's referring to two control plane working together as a logical single control plane, please update the text to remove confusion
In 13-2: https://learning.oreilly.com/library/view/istio-up-and/9781492043775/assets/iuar_1302.png
1. there are no call-outs but the writing suggested there are call-outs
2. If the text refers to diagram 13-1, it's missing #5, and the other call outs do not make sense
3. The diagram does not show Istio control plane on the other cluster

The paragraph after Example 5-8 says "Notice that only the istio-system namespace has the istio-injection label assigned" In fact, Example 5-8 shows the default and Docker namespaces labeled with a value of enabled.

First, the reader isn't told where to get the envoy.yaml in the command. There isn't one included in the Istio distribution.
Second, the command line option `-d 80:10000` says to map container port 10000 to host port 80. However, the following paragraph says to open port 15000 on the localhost. Either the command needs to change or the paragraph needs to change.

Extraneous apostrophes in a couple of the last sentences of this chapter.
"On the list of certificates used by productpage pod’s service proxy, ’you should see three files (see Example 5-14)."
"In theory you could use Envoy to create the state of the world; however, Pilot is responsible for configuring Envoy service proxies, the Istio configuration, and service discovery data.’"

The restart parameter should be `Never` not `never` as the option is case-sensitive.
$ kubectl run -i --rm --restart=never dummy --image=tutum/curl:alpine -n istio-system --command \
-- curl -v '...'
