Search Results for: vSphere with Kubernetes

I just learned that SSL certificate for VMware's vSphere with Tanzu Content Library (https://wp-content.vmware.com/v2/latest/lib.json) had just been updated a few days ago and this will have an impact for anyone who had subscribed to the Content Library prior to the certificate update.

Since I had setup the subscribed Content Library several months back, all the OVAs at the time were already sync'ed and there are no immediate errors when the "Fetch Content Library" task is performed (which will be fixed in a future release). However, I was seeing some strange issues with deploying specific versions of Kubernetes and I did not think much of it and deploying another version was fine, so I figured maybe it was just my setup. I also had another lab, so I ended up using that environment most recently.

It is only until you click on a specific Content Library Item and perform a manual sync will you see the following error, which indicates you are affected:

A general system error occurred: HTTP request error: cannot authenticate SSL certificate for host wp-content.vmware.com.

The quickest way to check whether you are affected is by looking at the configured SSL Thumbprint of your subscribed Content Library and comparing that to the vSphere with Tanzu Content Library endpoint.

Unfortunately, the configured SSL Thumbprint for the subscribed Content Library is not visible in the vSphere UI, but this information is available in the vSphere Content Library API.

I just put together this quick PowerCLI snippet which will retrieve the SSL Thumbprint for your subscribed Content Library and compare to the current thumbprint. If it does not match, you will get an error message printing out the current SSL Thumbprint.

$SubscribedCLName = "TKG-Content-Library"
$TKGCLThumbprint = "01:8D:FD:13:A6:9E:CA:AC:CB:7C:67:18:C1:47:11:8C:64:91:5D:C9"

$contentLibraryService = Get-CisService com.vmware.content.library
$LibraryIDs = $contentLibraryService.list()

foreach($libraryID in $LibraryIDs) {
        $library = $contentLibraryService.get($libraryID)
        if($library.name -eq $SubscribedCLName) {
            $ContentLibrary = $Library
            break
        }
}

if($ContentLibrary.subscription_info.ssl_thumbprint -ne $TKGCLThumbprint.toLower()) {
    Write-Error "SSL Thumbprint $($ContentLibrary.subscription_info.ssl_thumbprint) for $SubscribedCLName does not currently match!`n"
}

The fix is straight forward, simply edit the settings of your subscribed Content Library, do not make any changes and then click on OK. Since the configured SSL Thumbprint no longer matches the hosted Content Library, you will be prompted with an action to confirm the new thumbprint and then you can save the settings.

As of right now, the SSL Certificate for the hosted vSphere with Tanzu Content Library is valid until July 7, 2022 and I expect that VMware will replace the TLS certificate prior to that date and this operation will need to be performed again. Since this issue was initially reported internally, I have also asked to see if an official VMware KB to be published.
