6. Table of Contents 1. CI/CD using GitLab 1. CI/CD Workflow 2. CI/CD Terms 3. CI/CD Tools Analisys 2. Infrastructure as Code 1. What’s Infrastructure as Code? 2. Infrastructure as Code Workflow 3. Terraform as Code 3. GitOps Approach 4. CNCF (Cloud Native) 1. What’s CNCF? 2. Projects & initiatives & GitOps 3. CNCF Landscape 5. Demo (Hand-on DevOps)
7. What’s the purpose of this? Let’s start discuss the real objetive
8. Bringing some questions… Why you are using GitLab, Terraform and AWS? How are these tools integrating? How it works? What’s the connection of this with the DevOps? 8
9. Roadmap 9 1 3 5 6 4 2 DevOps (Collaboration, Automation, Communication) Infrastructure as Code (Terraform, Pulumi, Ansible) Cloud Native (Argo CI, Kubernetes, Crossplane, FluxCD) Continuous Integration & Continuous Delivery Jenkins/GitLab/GitHub Actions GitOps (Infrastructure Automation using Git) Automated DevOps workflow (Comming soon apps bringing scale, elasticity, resiliency, flexibility)
10. 1. CI/CD – Continous Integration & Continuous Delivery Bringing some essential concepts
12. 12 Cloud Native Glossary DevOps CI/CD Infrastructure as Code Terraform CNCF Kubernetes Containers Cloud Cluster Machine Learning Ansible Git K8S Kubelet GitOps
13. GitLab CI/CD Pipelines For every stage of the DevOps Lifestyle 13
15. GitLab Pipeline Example
16. CI/CD Tools Analysis 16 Jenkins Open source automation server which enable developers to build, test and deploy their app. GitLab Not a Open source tool. Pipeline as Code feature, pipeline based on YML files. Actions is a CI/CD tool for GitHub workflow. Pipelinein YML files, support many Devops Tools. GitHub Actions A CD Tool focused on GitOps workflow inside Kubernetes. Argo CD
17. 2. Infrastructure as Code Bringing some essential concepts
18. What’s (IaC) Infrastructure as Code? Basically IaC is a way to use code instead manual process to create and provisioning the resources on Cloud environment. 18
19. Infrastructure as Code Workflow 19
20. Infra as Code (IaC) with Terraform to provision an autoscaling group 20
21. Terraform demonstration diagram 21 AWS API’s Terraform main.tf Azure declarative Infrastructure as Code (IaC)
22. Terraform process is easy 22 1 2 3
23. How Terraform calls the Cloud providers 23
24. Terraform x Crossplane Basically everything is called via API’s. The Crossplane keeps the eyes on the providers API’s until to modify the infrastructure 24
25. 3. GitOps Bringing some essential concepts
26. 4. CNCF Bringing some essential concepts
27. “As part of the Linux Foundation, we provide support, oversight and direction for fast-growing, cloud native projects, including Kubernetes, Envoy and Prometheus”. 27
