Versioning

This project uses a .version file at the root of the repo which the pipeline reads from and does a git tag.

When you intend to commit to main, you will need to increment this version. Once the project is merged, the pipeline will kick off and tag the latest git commit.

Development

Prerequisites

• terraform
• terraform-docs
• pre-commit
• golang
• golint

Configurations

• Configure pre-commit hooks

  pre-commit install
  

Versioning

while Contributing or doing git commit please specify the breaking change in your commit message whether its major,minor or patch

For Example

git commit -m "your commit message #major"

By specifying this , it will bump the version and if you don't specify this in your commit message then by default it will consider patch and will bump that accordingly

Tests
