x509: certificate signed by unknown authority when deploying Management Cluster from Windows

Upon completion of Install the Tanzu CLI steps for Windows, you may encounter the following when performing tanzu management-cluster create --ui:

PS > tanzu management-cluster create --ui
Downloading TKG compatibility file from 'projects.registry.vmware.com/tkg/framework-zshippable/tkg-compatibility'
Error: unable to ensure prerequisites: unable to ensure tkg BOM file: failed to download TKG compatibility file from the registry: failed to list TKG compatibility image tags: Get "https://projects.registry.vmware.com/v2/": x509: certificate signed by unknown authority
  tanzu management-cluster create [flags]

To workaround this, edit %USERPROFILE%\.config\tanzu\tkg\config.yaml with the following, then retry management cluster setup:

    version: ""
Bootstrap platformWindows
Target platformAny
Affected versionsv0.2.1

Failed to create inotify errors

Occasionally there are failures during management cluster deployment. In the case where deployment fails at the step indicating “Install providers on management cluster”, you may see the following error in the capx-controller-manager logs when following the Troubleshoot Clusters with Tanzu Diagnostics instructions.

Failed to create inotify object: Too many open files

This can be more common when the system being used for deployment already has several containers running.

On Linux, this issue can be resolved by increasing the inotify watch limits using these commands:

sysctl fs.inotify.max_user_watches=1048576
sysctl fs.inotify.max_user_instances=8192

After running those commands you should be able to retry deploying a managment cluster.
