Creating custom viz plugin

[arnabneogi86]

Hi,
I'm trying to create custom viz plugins following the url:
https://preset.io/blog/building-custom-viz-plugins-in-superset-v2/

For releasing the plugin, I dont want to use superset's released code. I have already set up docker with postgres with your image.
Is there a way to reference your image and still add the custom plugins?
For development, I'm running superset's git code and then running dev-server to show the custom viz.
Just dont want to create image from that and want to use your image.
