Page 207-208 "Synk"	The section is called "Synk", and contains a few references to "Synk" but it should read "Snyk". The hyperlink is OK and goes to the right snyk.io website. We had an argument at work on how to say snyk (sneak, snake, etc) and I still don't know :) Note from the Author or Editor: Thanks for catching this!	Samuel Beaulieu	Aug 20, 2022
Page 143 Image pull policy	On page 143, re Image pull policy it states a wrong but popular misunderstanding for the setting 'Always'. It does not always pull the image and lead to poor performance. It is similar to running ´docker pull’ which does not pull existing images (unless they have changed). Here are the kubernetes doc on the subject: Always « every time the kubelet launches a container, the kubelet queries the container image registry to resolve the name to an image digest. If the kubelet has a container image with that exact digest cached locally, the kubelet uses its cached image; otherwise, the kubelet pulls the image with the resolved digest, and uses that image to launch the container. » https://kubernetes.io/docs/concepts/containers/images/#image-pull-policy Note from the Author or Editor: Good catch, thanks for pointing this out!

Page not applicable in digital book 2nd paragraph Chapter 4	https://learning.oreilly.com/library/view/cloud-native-devops/9781098116811/ch04.html#:-:text=creates%20a%20Kubernetes%20resource%20called%20a%20Deployment Chapter 4 second paragraph states - "Under the hood, the `kubectl run` command creates a Kubernetes resource called a Deployment" Shouldn't this be "...creates a Kubernetes resource called a `Pod`"? ``` kubectl run --help Create and run a particular image in a pod. ``` Note from the Author or Editor: Thanks for catching this. You are correct that kubectl run now creates a Pod. In earlier versions it would create a Deployment. We updated the wording in a few other places in the book for this change, but this one got missed. Thanks again for submitting!	Arka	Jun 05, 2022
