tomsriddle/705.603spring24 repository overview

⁠This is the Docker Example Image as a part of the Portfolio Setup

⁠Overview

As a part of Assignment 1 for Portfolio Setup we have published a docker image to Docker Hub. The repository itself is taken from https://github.com/JWHPortfolio/DockerExample⁠ which runs a Python Linear Regression to generate outputs.

⁠Local Development Environment used for building image

• Apple Mac M1 chip
• Sonoma 14.1.2
• Docker Desktop for Mac 4.26.1 (131620)

⁠Changes Made over Initial Image

Following changes were made on the repository in order to push the image

• In requirements.txt instead of sklearn I specified scikit-learn. W/o this I encountered the following error * The 'sklearn' PyPI package is deprecated, use 'scikit-learn' rather than 'sklearn' for pip commands.* . For more details we can look at https://towardsdatascience.com/scikit-learn-vs-sklearn-6944b9dc1736⁠

• During building using buildx while the build succeeded it did not publish any image to the local docker repository. docker image ls did not show the successfully built image. To resolve this I had to use the --load parameter and also remove one of the multi arch arguments. Details of this issue can be found here https://github.com/docker/buildx/issues/59⁠. This solution finally worked https://github.com/docker/buildx/issues/59#issuecomment-1168619521⁠

• In order to push a readme to Docker hub I also installed a CLI Plugin pushrm https://poweruser.blog/pushing-a-readme-file-to-docker-hub-68200bc4bf71⁠. Using this executing docker pushrm REPOSITORY:IMAGE⁠ pushed the readme file

⁠Built Images

Prior to leveraging the experimental feature of Use containerd for pulling and storing images

After resolving the issue with --load and multi arch parameters, we can see the following

⁠Docker Run

I created an output directory on my local host. Executing docker run had the following output

The output directory had the following files
