why is my application so large?

I have a Python FastAPI API using a few libraries, but flyctl deploy takes FOREVER and I think it’s related to the docker container sizes.

I didn’t setup docker, this is was all done by flyctl launch. Why do I have a docker container layer with 5+GB?

I used to have a ton of files in my working directory, but I’ve since deleted them. Do I have to wipe a cache somewhere? Thanks in advance

Assuming you are deploying via a Dockerfile, it would be helpful to share both the Dockerfile and the contents of .dockerignore.

Meanwhile, try creating a file with the following contents:

FROM ubuntu
COPY . .

Then running:

fly console --dockerfile Dockerfile.test -C bash

And from there run:

du | sort -n

What this will do is create an ephemeral machine, upload your source, and create a shell where you can explore.
