Best Practices 39
•Everything is in version control •Use Ansible inventory for environment specific information •Use Ansible Vault for secure storage for passwords •Generate Jenkins Jobs automatically via Job DSL • GitLab REST API •One Click Release & Deployments Best practices_ 40 Automate Everything
•All application run in Docker container •Environment independent Docker images •Use latest OS version (recent Kernel) •Use fixed Docker / Ansible versions •Have a clone of every system for testing new versions • incl. CI/CD Pipeline •Create User / Group (uid/gid) per Application Type • required for volume mount permissions •Do not run Docker Container under root! Docker_ 41 Stable Docker Setup
42
•Company Proxies • HTTPs / Man-in-the-Middle •Self-signed Certificates (HTTPs) •Freedom to spin up servers using Terraform •Automate network configuration •Keynote • Jean-Jacques van Oosten: "Do not compromise!" Enterprise Environments_ 43 Typical problems
