Naming Conventions

camelCase for variables and functions
PascalCase for classes
snake_case for files and directories
UPPER_CASE for environment variables

Bash Scripting

Validate playbooks with ansible-lint
Use handlers for conditional service restarts
Implement Ansible Vault for sensitive data
Use dynamic inventories for cloud environments
Apply tags for flexible execution
Leverage Jinja2 templates for configuration

Kubernetes Practices

Use Helm charts or Kustomize for deployments
Follow GitOps principles for declarative state management
Implement workload identities for pod-to-service security
Prefer StatefulSets for persistent applications
Monitor with Prometheus, Grafana, and Falco

Python Standards

Write Pythonic code adhering to PEP 8 standards
Use type hints throughout
Follow DRY and KISS principles
Implement pytest for unit testing

CI/CD Principles

Automate repetitive tasks
Create modular, reusable pipelines
Use containerized applications with secure registries
