kamranazeem/centos-multitool image - ErrImagePull

[themsay]

Your tutorial is really helpful. I have two things to point at on https://github.com/Praqma/LearnKubernetes/blob/master/kamran/Kubernetes-The-Hard-Way-on-BareMetal.md

1. As I was going through this I hit an issue with your test image kamranazeem/centos-multitool. I don't know if the problem is from my setup?

   
   $ kubectl run centos-multitool --image=kamranazeem/centos-multitool
   deployment "centos-multitool" created

$ kubectl get pods -o wide -w NAME READY STATUS RESTARTS AGE IP NODE centos-multitool-1226373562-rb2md 0/1 ImagePullBackOff 0 53s 10.200.0.14 worker-1 nginx-158599303-7jkwz 1/1 Running 3 1d 10.200.1.13 worker-2 nginx-158599303-p89b2 1/1 Running 3 1d 10.200.0.13 worker-1 centos-multitool-1226373562-rb2md 0/1 ErrImagePull 0 1m 10.200.0.14 worker-1 centos-multitool-1226373562-rb2md 0/1 ImagePullBackOff 0 1m 10.200.0.14 worker-1 centos-multitool-1226373562-rb2md 0/1 ErrImagePull 0 1m 10.200.0.14 worker-1 centos-multitool-1226373562-rb2md 0/1 ImagePullBackOff 0 1m 10.200.0.14 worker-1

2. I suggesting instead of extracting the PodCIDR information with https://github.com/Praqma/LearnKubernetes/blob/master/kamran/Kubernetes-The-Hard-Way-on-BareMetal.md#managing-the-container-network-routes steps.

You can simple get all at once without container with command:

$ kubectl get nodes --output=jsonpath='{range .items[*]} {.spec.podCIDR} {.spec.externalID} {"\n"}{end}' 10.200.0.0/24 worker-1 10.200.1.0/24 worker-2

or for each node can be done with below: 

$ kubectl get nodes --output=jsonpath='{range .items[*]}{.spec.podCIDR} {.spec.externalID} {"\n"}{end}' | grep worker-1 | awk '{print $1}' 10.200.0.0/24

NB: 'worker-1' and 'worker-2' is my worker node hostname(s).

Thanks once again for your time.

Hi! Thanks for your feedback!

For the multitool, the new image is actually here: https://github.com/Praqma/Network-MultiTool

Thanks for the short-hand / simplified command to extract network routes information. Very helpful. Thanks!

Regards, Kamran
