UGain - containers and Kubernetes Smoke Test

This repository contains the necessary files to run the lab session about (Docker) containers and Kubernetes.

Initial setup

• How to install the required software on Windows.
• How to install the required software on Linux.
• How to install the required software on Mac.

Getting started

Warning: opening the workspace devcontainer will create a new kind kubernetes cluster on your host system. If you already have a kind cluster with the name ugain that should not be deleted do not open this workspace!

1. Clone this repository to your computer using git.

2. Open lab-containers-smoketest.code-workspace using Visual Studio Code.

   code lab-containers-smoketest.code-workspace

3. Choose "Yes, I trust the authors", so VSCode enables regular mode.

   

4. Click on the "Remote" icon on the bottom left of VSCode.

   

   1. Choose the option "Reopen in container" from the command palette.

      

   2. The container will be automatically created based on the configuration included in the lab files.

5. Wait until the containers are set up. This can take a few minutes because the container needs to be pulled and built. You can check the progress by clicking "Starting Dev Container (show log)" in the notification on the bottom right of VSCode.

6. When the containers are setup, Click on Terminal -> Run Task -> start smoke test. A terminal will appear with the smoketest running. The output should look somewhat like the following:

 *  Executing task: ./smoketest.sh
