Main Tasks (Python app): - Add production-ready Dockerfile with best practices - Non-root user (appuser) - Specific base image version (python:3.13-slim) - Proper layer ordering for caching - Health check implementation - Create .dockerignore for optimized build context - Add Docker section to README.md with usage examples - Create comprehensive LAB02.md documentation - Push image to Docker Hub (ellilin/devops-info-service:v1.0.0) - Final image size: 208MB Bonus Task (Go app - Multi-stage build): - Implement multi-stage Dockerfile for Go application - Stage 1: Builder (golang:1.21-alpine) for compilation - Stage 2: Runtime (alpine:3.19) for minimal footprint - Static binary with stripped symbols (-ldflags='-s -w') - Create .dockerignore for Go - Build 31.6MB final image (91% smaller than single-stage) - Push to Docker Hub (ellilin/devops-info-service-go:v1.0.0) - Create detailed LAB02.md documentation explaining: - Multi-stage strategy and benefits - Size comparison analysis - Security implications - Technical explanation of each stage Security: - Both apps run as non-root user - Minimal base images for reduced attack surface - No build tools in production images - Proper health checks implemented
…e CodeQL to v4, fix SARIF upload conditions
Lab 6 Implementation (10 pts + 2.5 bonus): Main Tasks: - Task 1: Refactored roles with blocks and tags (2 pts) * Common role: package/user management blocks with rescue/always * Docker role: installation/configuration blocks with error handling * Comprehensive tag strategy for selective execution - Task 2: Upgraded to Docker Compose (3 pts) * Renamed app_deploy to web_app * Created Docker Compose template with Jinja2 * Implemented role dependencies (web_app depends on docker) * Deployed using community.docker.docker_compose_v2 module - Task 3: Implemented wipe logic (1 pt) * Double-gating with variable + tag for safety * Clean reinstallation workflow (wipe → deploy) * Support for removing volumes and images - Task 4: CI/CD with GitHub Actions (3 pts) * Created ansible-deploy.yml workflow * Integrated ansible-lint for syntax checking * Automated deployment on push to main/master * Added verification steps for application health * Configured path filters for efficiency - Task 5: Documentation (1 pt) * Created comprehensive LAB06.md * Documented all implementations with examples * Answered all research questions * Added testing results and evidence Bonus Tasks: - Bonus Part 1: Multi-App Deployment (1.5 pts) * Created separate variable files for Python and Go apps * Implemented deployment playbooks for each app * Role reusability with different configurations * Independent wipe functionality per app - Bonus Part 2: Multi-App CI/CD (1 pt) * Separate workflows for Python and Go apps * Path filters for independent triggering * App-specific verification steps Infrastructure: - Updated Terraform for Lab 6 - Added security group rules for ports 5000, 5001 - Opened SSH for GitHub Actions self-hosted runner - Updated all resource tags to Lab06 Files Changed: - ansible/roles/common/tasks/main.yml (blocks & tags) - ansible/roles/docker/tasks/main.yml (blocks & tags) - ansible/roles/web_app/ (Docker Compose, wipe logic) - ansible/vars/ (multi-app variables) - ansible/playbooks/ (deployment playbooks) - .github/workflows/ (CI/CD workflows) - terraform/ (infrastructure updates) - README.md (status badges) - ansible/docs/LAB06.md (documentation)
- Deploy Loki 3.0 with TSDB, Promtail 3.0, Grafana 12.3 - Add JSON structured logging to Python and Go apps - Create 4-panel Grafana dashboard with LogQL - Configure production settings (resources, security, health checks) - Add bonus: Ansible monitoring role for automation - Documentation with architecture and setup guide - Screenshots placeholders for 9 required evidence captures
