Operations and DevOps

Coming Soon

This lesson will teach you modern DevOps practices for deploying and managing Erlang applications at scale. You’ll learn how to:

• Build CI/CD pipelines for Erlang applications
• Containerize Erlang applications with Docker
• Implement infrastructure as code with Terraform
• Set up automated deployment and rollback strategies
• Create monitoring and alerting for production systems

What You’ll Build

By the end of this lesson, you’ll have implemented:

• Complete CI/CD pipeline with automated testing
• Docker containerization for Erlang applications
• Kubernetes deployment manifests
• Infrastructure as code with Terraform
• Automated monitoring and alerting setup

Key Concepts Preview

# Dockerfile for Erlang application
FROM erlang:24-alpine

WORKDIR /app
COPY _build/prod/rel/chat_server ./
EXPOSE 8080

CMD ["./bin/chat_server", "foreground"]

# GitHub Actions CI/CD
name: Build and Deploy
on:
  push:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Setup Erlang
        uses: erlef/setup-beam@v1
        with:
          otp-version: "24"
          rebar3-version: "3.18"
      - name: Run tests
        run: rebar3 eunit

This lesson builds on the scaling strategies from Lesson 31 and prepares you for the advanced OTP patterns we’ll explore in Lesson 33.
