Overview

Currently, the docker/go-events project does not have CI/CD automation set up. To facilitate the automation process for Continuous Integration (CI) and Continuous Deployment (CD), the following next steps are proposed for implementing a CI/CD pipeline.

Next Steps for Setting Up CI/CD

1. Select a CI/CD Tool: Choose a CI/CD tool that suits your workflow. Common options include GitHub Actions, GitLab CI, CircleCI, Travis CI, and Jenkins.

2. Create Configuration Files: Depending on the selected CI/CD tool, create the necessary configuration files in the root directory of the project.

3. Define Build and Test Scripts: Ensure build and test scripts are defined to compile the Go code and run tests. The following example showcases a basic test script.

Example Build Script (build.sh)

Create a build.sh script to compile the application.

#!/bin/bash

set -e

echo "Building the Go application..."
go build -o go-events ./...
echo "Build completed successfully!"

4. Define Test Commands: Create commands to run tests during the CI process. Below is an excerpt that could be included in your CI configuration to run Go tests.

Example Test Command

go test ./... -v

5. Integration with Docker: If containerization is a requirement, create a Dockerfile that defines the image for the application. Below is a basic Dockerfile example.

Example Dockerfile

FROM golang:1.19 AS builder

WORKDIR /app
COPY . .

RUN go build -o go-events ./...

FROM gcr.io/distroless/base

COPY --from=builder /app/go-events /go-events

ENTRYPOINT ["/go-events"]

6. Configure CI/CD Workflow: Define the CI/CD pipeline in your chosen CI/CD tool. Below is a hypothetical example of what a GitHub Actions workflow might look like, placed in .github/workflows/ci.yml.

Example GitHub Actions Workflow

name: CI

on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Set up Go
        uses: actions/setup-go@v2
        with:
          go-version: '1.19'

      - name: Install Dependencies
        run: go mod tidy

      - name: Build
        run: ./build.sh

      - name: Test
        run: go test ./... -v

Conclusion

To implement CI/CD for the docker/go-events project, consider the outlined steps to select the appropriate tools, create necessary configuration files, and ensure build and test scripts are in place. Setting up a CI/CD pipeline will enhance the development workflow by automating code validation and deployment processes.
