Here's how the components will work together: Flow: Developer pushes code → Jenkins (CI/CD orchestrator) → Triggers Ansible playbooks → Ansible deploys to Kubernetes → Uses ServiceAccount with proper RBAC
Here's how everything works together:
-
Architecture Overview: Jenkins Pod: CI/CD orchestrator, triggers on code changes Ansible Pod: Configuration management and deployment executor ServiceAccount: Shared identity with cluster-wide permissions RBAC: ClusterRole with necessary permissions for both pods
-
Deployment Flow: Code Push → Jenkins Pipeline → Ansible Playbook → Kubernetes Deployment
-
Key Integration Points: Shared ServiceAccount: Both Jenkins and Ansible pods use jenkins-ansible-sa with proper RBAC permissions API Server Access: ServiceAccount token automatically mounted at /var/run/secrets/kubernetes.io/serviceaccount/ kubectl Access: Both pods have kubectl binary mounted from host Ansible Playbooks: Stored in ConfigMaps, accessible to both pods Communication: Jenkins triggers Ansible via Kubernetes Jobs or direct pod execution
-
Why This Design: Jenkins: Handles CI/CD orchestration, webhooks, notifications, and pipeline management Ansible: Executes actual deployments, configuration management, and infrastructure tasks Separation of Concerns: Jenkins focuses on workflow, Ansible on execution Scalability: Can spin up multiple Ansible execution pods as needed
