Description:

This sample app combines both options below

Option 1:

• Python coding exercise
• Write a small class that retrieves data from an API

Option 2:

• Practical docker exercise
• Candidate should have docker installed
• Will be working to set up and run a basic app (that will be created) in docker

Option 1

The python app pulls the latest release from the GitHub API with a small class as well as another small class for downloading te release binary.

Option 2

Uses a docker container to 'build' the 'Option 1' basic app into a binary inside a container using:

docker build --target final --tag sample .

This builds a container with the PyInstaller binary setup with an entrypoint so it can be executed without specifying the binary:

docker run -it --privileged -v $(pwd):/tmp localhost/sample -d -o /tmp

Note: the '-d' flag means 'download latest' and '-o' is the volume mounted directory where the latest binary will be download.

Sample Output

$ docker run -it --privileged -v $(pwd):/tmp localhost/sample -d -o /tmp
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Discovered the latest version from the GitHub API: v2.213.2.
