Docker image is huge (6.5 GB)

[applejag]

Describe the bug
The Emanote Docker image is over 6 GB in size

$ podman images sridca/emanote:latest
REPOSITORY                TAG         IMAGE ID      CREATED       SIZE
docker.io/sridca/emanote  latest      3fafc9417949  52 years ago  6.49 GB

(funny it says "CREATED 52 years ago" 🤭)

To Reproduce

1. docker pull sridca/emanote:latest
2. docker images sridca/emanote:latest
3. See results

Expected behavior
Docker image sizes are usually in the range of 1-200MB in size.

As the built emanote binary on my machine is ~200MB then the Docker image should be in that size range as well.

Additional context
For comparison of some images I already had locally:

// typical dev images:

Almost as big as the Unity3D editor bundled with the IL2CPP compiler :P

Note: I'm using Podman, which lists the uncompressed file size. On Docker Hub it lists the compressed file size, which is only at 1GB (instead of 6.5 GB): https://hub.docker.com/layers/emanote/sridca/emanote/latest/images/sha256-c5d836ea139e51d4094baf0f4544aec2a123b53abd91b015a01ea3ce28acca5d?context=explore
