How to mount external windows file share inside pod hosted on AWS EKS?
You could modify the cloudformation stack to install the drivers after startup, see https://amazon-eks.s3-us-west-2.amazonaws.com/cloudformation/windows-public-preview/amazon-eks-cfn-quickstart-windows.yaml
It references https://amazon-eks.s3-us-west-2.amazonaws.com/cloudformation/windows-public-preview/amazon-eks-windows-nodegroup.yaml which contains the following powershell startup lines
<powershell>[string]$EKSBinDir = "$env:ProgramFiles\Amazon\EKS"[string]$EKSBootstrapScriptName = 'Start-EKSBootstrap.ps1'[string]$EKSBootstrapScriptFile = "$EKSBinDir\$EKSBootstrapScriptName"[string]$cfn_signal = "$env:ProgramFiles\Amazon\cfn-bootstrap\cfn-signal.exe"& $EKSBootstrapScriptFile -EKSClusterName ${ClusterName} ${BootstrapArguments} 3>&1 4>&1 5>&1 6>&1$LastError = if ($?) { 0 } else { $Error[0].Exception.HResult }& $cfn_signal --exit-code=$LastError ` --stack="${AWS::StackName}" ` --resource="NodeGroup" ` --region=${AWS::Region}</powershell>Add your custom installation requirements and use this new stack when launching your nodes
We ultimately end up using code approach using SharpCifs.Std for some of the reasons including:
- Avoid any possible environment configuration issues with involvement of cluster admins esp installing Flexvolume based CIFS drivers across Kubernetes cluster.
- Code native turned out to be much better control
- available in with nuget package
- compatible with .NET Standard 2.x which means .NET Core 2.x
- File share operations aren't read/write intensive
