@smallzhongfeng Thanks for your work.. When I'm working on #793, I made similar changes. However it seems too much changes and it was primary to label cluster name and I thought it wasn't worth it.

Do you have some more input for this one? I'm OK to accept this PR with some comments.

[smallzhongfeng]

Thanks @advancedxy , but currently, I'm sorry that I haven't found a better way to make the code more elegant.. :-(

[smallzhongfeng]

If you have time, please help me take a look again. Thanks @advancedxy :-)

[advancedxy]

LGTM, except one minor comment.

[smallzhongfeng]
