Documentation error for powershell script of kubectl installation

• [ ] Feature Request
• [x] Bug Report

Problem:
PowerShell script for windows does not work. An exception occurred once trying to download kebuctl.

Proposed Solution:
update script with download link from
$downloadlink = "($req.Links | where href -Match "kubectl.exe").href"
to "https://storage.googleapis.com/kubernetes-release/release/v1.12.0/bin/windows/amd64/kubectl.exe" or set this text as a link on the page.

Page to Update:
https://kubernetes.io/docs/tasks/tools/install-kubectl/

1.12

You can now start kubectl from C:\Users\vladimir.shmidt.kube\kubectl.exe
copy your remote kubernetes cluster information to C:\Users\vladimir.shmidt.kube/config

Facing exactly the same issue

[tengqm]

Sounds like the install-kubectl.ps1 script from PSGallery is broken. Not sure how are we supposed to fix it. Should we remove the "Install with Powershell from PSGallery" section all together? We already have the curl way to download and install kubectl.exe on Windows (see later in that page).

[vladimir-shmidt]

install-kubectl.ps1 is trying to crawl docs page and find a link with cube installer but somebody removed it from the page so script is broken now

[petenys]

C:[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

then install

[barry8schneider]

@petenys - I had to remove the C: but this fixed teh problem. Thanks

[it-praktyk]

@bottkars, do you publish somewhere the source of the 'install-kubectl.ps1' script?

I can prepare the PR to resolve that.

new version 1.7 of installer is published to Gallery. can be closed for now

[barry8schneider]

@bottkars I think you might have uploaded the 1.6 code to the gallery for 1.7. The header still references 1.6 and the code looks exactly the same:
https://www.powershellgallery.com/packages/install-kubectl/1.7/Content/install-kubectl.ps1
<#PSScriptInfo
.VERSION 1.6
.GUID 32a11a36-f91c-4241-a11f-af0cf3e90f38
.AUTHOR Karsten.[email protected]

[bottkars]

don´t trust that one.

please do "install-script install-kubectl -MinimumVersion 1.7 -force -verbose“

the script should be installed in $HOME/Documents/WindowsPowerShell/Scripts/install-kubectl.ps1

If so, do

ise -f $HOME/Documents/WindowsPowerShell/Scripts/install-kubectl.ps1

You will see it should be 1.7

Publish-Script does not allow to upload same version twice :-)

I've tested it, works correctly on W2K8 R2 and PowerShell 3.0.

IMHO, the issue can be closed now.

[bottkars]

thanks for verifying Wojciech !

Thanks, Barry. After I installed docker, the issue fixed. Not sure why.
