1. Journey in Implementing CI/CD Imam Muslim Aldi Doanta Kurnia
2. Our Missions 1. Establish data-driven policy making 2. Accelerate government digital transformation 3. Simplify people’s lives with digital technology
3. OKR Organization Values Continuous learning Aligned autonomy Metric-driven & Impact-oriented Agile development Encourage automation Innovative Data-driven Service oriented Responsive Adaptive Dynamic Engineering Culture Engineering Practice Scrum CI/CD TechTalk 360o Feedback
4. Continuous learning Aligned autonomy Metric-driven & Impact Agile development Encourage automation Engineering Culture Engineering Practice CI/CD
5. Cloud Native Application 1. Elasticity = grow and shrink to fit in available resource 2. Resilience = fast automatic and recovery from failure 3. Agility = fast deployment, iteration and reconfiguration Cloud Native Landscape and Trail Map (https://github.com/cncf/trailmap)

13. Benefits and Challenges Benefits: - Automated, repeatable, reliable - Improvement in software quality and delivery speed - Engineer’s confidence and peace of mind Challenges: - Learning curve - Long-term result
14. Why We Use GitLab CI and Jenkins JDS is using GitLab CI dan Jenkins Jenkins GitLab CI - Open Source - Simple and easy to use - Many plugins to use - Complete documentation - Easy to Maintain - Free, 2000 minutes/month - Any Platform Git - Running locally
15. versioning: stage: versioning only: - branches script: - export VER=1.0 code_quality: stage: code_quality dependencies: - versioning script: - script GitLab CI Example stages: - versioning - code_quality - build - test - deploy_staging - deploy_prod deploy_staging_aws: stage: deploy_staging only: - master script: - script deploy_staging_eks: stage: deploy_staging only: - master script: - script deploy_prod_eks: stage: deploy_prod when: manual only: - master script: - script JOBS STAGES
16. Challenges
17. Learning YAML syntax for GitLab CI
18. Increasing complexity in config file April 2019 1 stage File size: 482 B December 2019 6 stages File size: 14 KB
19. Challenges Others: - Managing environment variables - GitLab Runner performance limitations - CI/CD optimization in pipeline duration
20. Case Study: Sapawarga Sapawarga API Total: 2164 pipelines, Successful: 1283 pipelines, Failed: 394 pipeline Success ratio: 76%
