Refer Error while building Docker image for custom app - #4 by revant_one
I did exactly this yesterday on the shared post.
Use GitHub - castlecraft/custom_frappe_docker for reference
Check this diff and make changes as per your app(s) Comparing main...isppme · castlecraft/custom_frappe_docker · GitHub
Share your app url and I’ll share a diff branch like isppme
You’ll have to run “docker build …” command to build the images
