Workflows Experiments

A simple Go application with GitHub Actions workflows demonstrating CI/CD and ChatOps slash commands.

Application

This repository contains a basic "Hello, World!" Go application.

Running locally

go run main.go

Building

go build -v ./...

Testing

go test -v ./...

GitHub Actions Workflows

Build Workflow

Located at .github/workflows/build.yaml, this workflow runs automatically on:

• Push to main branch
• Pull requests to main branch

It performs three jobs in parallel:

1. Build: Compiles the Go application
2. Test: Runs all tests
3. Lint: Runs golangci-lint for code quality

Slash Commands (ChatOps)

This repository implements slash commands for pull requests, similar to tektoncd/pipeline.

Available Commands

Comment on a pull request with these commands:

• /retest - Reruns failed GitHub Actions checks for the PR
• /build - Triggers an on-demand build and test of the PR

How It Works

1. Slash Command Routing (.github/workflows/slash.yaml)

   • Listens for issue comments
   • Dispatches commands to appropriate workflows
   • Requires write permission (maintainers only)

2. Command Handlers

   • .github/workflows/chatops_retest.yaml - Handles /retest
   • .github/workflows/chatops_build.yaml - Handles /build

3. Permissions

   • Only users with write access can trigger slash commands
   • Commands only work on pull requests

Example Usage

On a pull request, comment:

/retest

The bot will:

• Find failed workflow runs for the PR
• Rerun the failed jobs
• React with 👍 on success
• Add a comment with logs if it fails
