Bumper

Overview

This Go application provides a simple version bumping service. It includes two primary functionalities: bumping the version of a given semantic version string and retrieving the current version of the application. The application leverages the go-semver package for semantic version parsing and operations, and the gorilla/mux package for routing HTTP requests.

Features

• Version Bumping: POST requests to /bump will increment the specified version according to the specified mode (major, minor, or patch).
• Get Current Version: GET requests to /version will return the current version of the application.

Requirements

• Go programming language
• External Go packages:
  • github.com/adamwasila/go-semver
  • github.com/gorilla/mux

Installation

To run this application, you need to have Go installed on your system. After installing Go, you can set up the project by following these steps:

1. Clone the repository to your local machine.
2. Navigate to the project directory.
3. Run go get to install the required dependencies.

Usage

To start the server, run the following command in the terminal from the project directory:

go run main.go

Running with Docker

To run the application using Docker, follow these steps:

1. Build the Docker image:

    make docker-build

2. Run the Docker container:

    make docker-run

Makefile Commands

• make test: Run tests.
• make build: Build the application.
• make clean: Clean the build directory.
• make run ARGS="<args>": Run the application with specified arguments.
• make docker-build: Build the Docker image.
• make docker-run: Run the Docker container.
• make docker-push: Push the Docker image to a registry.

Dockerfile

The Dockerfile uses a multi-stage build process:

• The first stage uses golang:1.19 to build the application.
• The second stage uses alpine:3.14 to create a lightweight container.
