DevOps Foundations: Implement Semantic Versioning Principles
In this lab, you’ll practice semantic versioning (semver). When you’re finished, you’ll have the skills and knowledge necessary to communicate compatibility clearly with semver.
Terms and conditions apply.
Challenge
Get Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
Challenge
Understand the Version of Your Code
To start the lab, you will become familiar with a provided project that has an existing semantic versioning as expressed in the git tags, and understand the purpose of versioning.
Challenge
Perform a Patch Update
A code fix results in a patch, and hence a patch update. You will notice and fix a problem in the code, then will properly increment the version to reflect the change and compatibility state with consumers of the project.
Challenge
Perform a Minor Update
Examine the code for an issue and add a new method that the consuming functions will call. Then, examine an issue and make a change that is a version increment judgment call.
Challenge
Perform a Major Update
You will change the implementation of the getCurrentPayload method, breaking the interface of the previous version, and necessitating a major version update.
Provided environment for hands-on practice
