How to copy files from worker nodes (Linux and Windows) to local machine?

1. You can copy files from Linux worker node by the following steps:

• Connect to the Linux node using kubectl enter command:

  kubectl enter <node>
  

• Open another shell and look for the connector-xxxxxx pod in default namespace:

  kubectl get pods
  

• Copy the file from connector pod which will be the Linux worker node to your local machine:

  kubectl cp connector-xxxxxx:/FilePathOnLinuxNode /DestPathOnYourLoaclMachine/Filename
  

  Example:

  kubectl cp connector-xxxxxx:/tmp/logs.zip /tmp/logs.zip
  

2. You can copy files from Windows worker node by the following steps:

Note: Username and Password are required for Windows node.

• Connect to the Windows node using kubectl enter command:

  kubectl enter <windows-node>
  

• Open another shell and look for the connector-xxxxxx pod in default namespace:

  kubectl get pods
  

• Exec to the connector pod which will be a Liunx node in your cluster:

  kubectl exec -it connector-xxxxxx -- bash
  

• Copy the file from Windows node to the Linux node using scp command:

  scp <WindowsNodeUserName>@<WindowsNodeNameOrIPaddress>:/FilePathOnWindowsNode /DestPathOnLinuxNode/Filename
  

  Example:

  scp azureuser@aksnp000000:/c:/Users/azureuser/aksn000000_logs.zip /tmp/aksnp000000_logs.zip
  

• Copy the file of Windows node from connector pod which will be the Linux worker node to your local machine:

  kubectl cp connector-xxxxxx:/FilePathOnLinuxNode /DestPathOnYourLoaclMachine/Filename
  

  Example:

  kubectl cp connector-xxxxxx:/tmp/aksnp000000_logs.zip /tmp/aksnp000000_logs.zip
