  kbcli cluster logs mycluster --tail=20
  
  # Display stdout info of specific instance my-instance-0 (cluster name comes from annotation app.kubernetes.io/instance)
  kbcli cluster logs --instance my-instance-0
  
  # Return snapshot logs from cluster mycluster with specific instance my-instance-0 (stdout)
  kbcli cluster logs mycluster --instance my-instance-0
  
  # Return snapshot logs from cluster mycluster with specific instance my-instance-0 and specific container
  # my-container (stdout)
  kbcli cluster logs mycluster --instance my-instance-0 -c my-container
  
  # Return slow logs from cluster mycluster with default primary instance
  kbcli cluster logs mycluster --file-type=slow
  
  # Begin streaming the slow logs from cluster mycluster with default primary instance
  kbcli cluster logs -f mycluster --file-type=slow

Options

  -c, --container string    Container name.
      --file-path string    Log-file path. File path has a priority over file-type. When file-path and file-type are unset, output stdout/stderr of target container.
      --file-type string    Log-file type. List them with list-logs cmd. When file-path and file-type are unset, output stdout/stderr of target container.
  -f, --follow              Specify if the logs should be streamed.
  -h, --help                help for logs
