I am very new to Docker but enjoying the study. Recently I have tried to build an image for a simple ML app that I had build earlier. I have used python:3.11-slim base image and installed a few dependencies. After the final build, the image size turned out to be 1.13 GB. How is this happening?

I am trying to build a Github Action that automatically compiles and publishes my dotnet core container and pushes the image to our Container Registry. Below is my Github Action file. How do I ensure that the C# source code is not embedded into the container image?

The Edge TPU Compiler (edgetpu_compiler) is a command line tool that compiles a TensorFlow Lite model (.tflite file) into a file that’s compatible with the Edge TPU (_edgetpu.tflite file).

I am trying to initiate a build pipeline from Github Actions. The host runner is on Azure VM. The step inside the workflow initiate a docker build as follows:

I am a beginner using Docker.When I tried to compile a dockerfile using docker, when I ran apt update, I got warnings “No system certificates available” and “GPG error The following signatures could not be verified because the public key is not available: NO_PUBKEY xxx”, which eventually resulted in an error “apt repository is not signed”. I searched Google for ways to solve the above problem. First, I tried to install ca-certificates using the apt install command, but the installation failed because the apt source was not updated. I then tried to add the missing key for apt “apt-key adv –keyserver keysever.ubuntu.com –recv-keys xxx”, but it reported an error that one of gnupg, gnupg2, and gnupgl was missing. I then tried to install the above three tools, but all failed because the apt source was too old (the specific error was: Package gnupg is not available, but is referred by another package. This may mean that package is missing, has been obleted, or is only available from another source). So I think I’m in an endless loop. I need to install some necessary tools to update the apt source, but the installation of these tools depends on me updating the apt source. So is there an effective way to update the public key in my docker without installing additional tools?
The following is part of my dockerfile:

Our project used to extract test report from docker build with Dockerfile:

I have been trying so many ways to extend the PATH envvar in my container.
Here is my currently last shot at it:
