I'm reading with O'Reilly safari books, so I don't know the page number.
In Chapter4 Section "Uninstalling Istio"
There is a part where apply is executed when kubectl delete should be executed.
Error
$ kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
Correct
$ kubectl delete -f samples/bookinfo/platform/kube/bookinfo.yaml
Note from the Author or Editor:
The reader's comment is correct. There is a multi-line code example under the Uninstalling Istio section toward the bottom of chapter 4:
$ for i in install/kubernetes/helm/istio-init/files/crd*yaml;
do kubectl delete -f $i; done
$ kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
$ kubectl delete -f samples/bookinfo/networking/bookinfo-gateway.yaml
The third line needs to be updated to replace "apply" with "delete" like this:
$ kubectl delete -f samples/bookinfo/platform/kube/bookinfo.yaml

Chapter 4. Uninstalling a Helm-Based Installation |
Location 1486 of 6814 (23%)
The Helm uninstall is missing the removal of the Istio CRDs. It should be after the deletion of the Istio resources and before the deletion of the istio-system namespace.
$ helm template install/kubernetes/helm/istio-init --name istio-init
--namespace istio-system | kubectl delete -f -
Note from the Author or Editor:
The following line should be incorporated into the existing two line code example:
"$ kubectl delete -f install/kubernetes/helm/istio-init/files"
So, the new code example under "Uninstalling a Helm-Based Installation" at the end of chapter 4 should read like so:
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system | kubectl delete -f -
$ kubectl delete -f install/kubernetes/helm/istio-init/files
$ kubectl delete namespace istio-system |

Chapter 5. Manual Sidecar Injection |
Location 1621 of 6814 (25%)
The example command to inject an Envoy sidecar to a running deployment without a source manifest is missing the deployment name.
$ kubectl get deployment -o yaml | istioctl kube-inject -f -
| kubectl apply -f -
It should be something like:
$ kubectl get deployment <deployment_name> -o yaml | istioctl kube-inject -f -
| kubectl apply -f -
Note from the Author or Editor:
The first code example under the "Manual Sidecar Injection" section in Chapter 5 needs updated to include "<deployment_name>" command, like this:
$ kubectl get deployment <deployment_name> -o yaml | istioctl kube-inject -f -
| kubectl apply -f - |

Chapter 5. Envoy's Functionality |
Location 1768 of 6814 (26%)
The first sentence has an extraneous trailing apostrophe.
"Like other service proxies, Envoy uses network listeners to inject traffic.'"
Note from the Author or Editor:
Good feedback. The extraneous apostrophe at the end of this sentence should be removed. |
