Hi @HarryHung,
Thank you for your PR addressing this issue. We avoid overwriting deployed images, so we need a few minor changes in your PR:

• Please create a folder at build-files/poppunk/2.7.8-x86_64_v3 and move your Dockerfile and README into it.
• Add the new version 2.7.8-x86_64_v3 to the main README.

Let us know if you have any questions.
