Problem installing K8s Master on GCP (exercise 2.2)

debashish

Hi,

I ran into problem with the installation itself in exercise 2.2, am following the code in LFD259 V2019-03-11 SOLUTIONS. When I run the KbsMaster.sh, kubectl was not installed. Following is the output I got. How do I get past this? It seems the issue is regarding incompatible CNI version. Note that I am using GCP trial and the VM was set up exactly following your video tutorial. Appreciate the help.

Install kubeadm and kubectl
OK

An issue at https://github.com/kubernetes/kubernetes/issues/75683 states that using 1.13.5 (or later) fixes this, do you recommend this?

Please ignore, I should read other posts in the forum already. Using v 1.13.5 solved my issue.

Hi Deb,
Keep in mind there may be slight differences between v1.13.5 and v1.13.1 (the release tested for lab exercises).
An easy fix for the v1.13.1 installation is to also install kubernetes-cni=0.6.0-00 when installing the 3 kube* components v1.13.1.
