Chap 2: Can't sign CSR (Minikube, Docker driver, Arm M1) about cka-study-guide

Ah-- that makes total sense! And yes, I was going to submit that whole block with the code tags as well. Thanks for the script, and I'll take a look at it this afternoon. Much appreciated.

CLOSING: Will submit errata. Error appears to be based on user local machine configuration.

Based on the error message you provided, it seems like you are missing the ~ character for the path to refer to .minikube in the user home directory. The path should be ~/.minikube/ca.crt. Alternatively, use the full path to the file.

Thanks, @bmuschko -- so that's a typo in the book, then, which I can log in the errata. But more importantly, if I put the ~ back in, then it at least finds the signature, but Docker still fails:

docker@minikube:~/cert$ openssl x509 -req -in johndoe.csr -CA ~/.minikube/ca.crt -CAkey ~/.minikube/ca.key -CAcreateserial -out johndoe.crt -days 364
Signature ok

Ugh, you are right. There's an issue with the formatting of that command in the book. In the text above the command, you can see another incorrect formatting <code>.... Would you mind sending that to the errata?

In regard to the commands, check this script I use during my live training: https://github.com/bmuschko/cka-crash-course/blob/master/exercises/01-rbac/create-user-context.sh

Side note: It seems like you installed minikube with a different user than docker. Therefore, it's not visible to the user.

I added this issue to the errata: https://app.oreilly.com/cs/portal/edit/errata/200061
