Course Outline
Infrastructure-as-Code Sovereignty
- Identify the risks associated with cloud consoles and SaaS IaC, including vendor lock-in and audit gaps.
- Examine Terraform architecture in depth, covering core components, providers, state management, and the plan/apply workflow.
- Conduct a comparative analysis of Terraform against alternatives such as Pulumi, Ansible, and CloudFormation.
Configuration Language and Providers
- Master HCL syntax: defining resources, data sources, variables, and outputs.
- Configure on-premise providers: Proxmox, libvirt, vSphere, and PowerDNS.
- Explore community providers and the fundamentals of custom provider development.
- Understand resource dependencies and the underlying graph theory.
State Management
- Evaluate the security implications of local versus remote state storage.
- Set up self-hosted backends using PostgreSQL, S3-compatible storage (MinIO), Gitea, and etcd.
- Implement state locking, encryption at rest, and robust backup strategies.
- Manage state migration and detect configuration drift.
Modules and Workspaces
- Structure modules with inputs, outputs, and versioning best practices.
- Build private module registries using Git tags.
- Ensure isolation across dev, staging, and production environments via workspaces.
- Leverage self-hosted alternatives to Terraform Cloud, such as Atlantis or Spacelift.
Provisioning and Lifecycle
- Integrate cloud-init and PXE for bare-metal provisioning.
- Utilize provisioners: local-exec, remote-exec, and file transfer.
- Leverage null resources and triggers for custom automation workflows.
- Manage resource destruction, planning, and tainting for safe rollbacks.
Security and Compliance
- Enforce variable validation and mark sensitive data appropriately.
- Implement policy-as-code for on-premise environments using Sentinel and OPA alternatives.
- Establish robust audit logging and plan file review processes.
CI/CD Integration
- Automate plan and apply workflows in GitHub Actions or Woodpecker CI.
- Integrate
terraform fmt,validate, and linting tools in pre-commit hooks. - Set up cost estimation and budget guardrails.
- Develop comprehensive rollback strategies and state recovery procedures.
Requirements
- Intermediate understanding of infrastructure-as-code concepts and cloud computing fundamentals.
- Practical experience with JSON, HCL (HashiCorp Configuration Language), and version control systems.
- Familiarity with on-premise virtualization platforms such as Proxmox and VMware.
Audience
- Infrastructure engineers responsible for provisioning bare metal servers and private cloud resources.
- DevOps teams managing on-premise resources through declarative configuration.
- Organizations actively seeking to avoid reliance on cloud control planes for managing infrastructure state.
