OpenTofu and Flux CD — Open-Source Alternatives in the DevOps Ecosystem

Hands-on training covering two key open-source tools in the DevOps ecosystem. Participants learn OpenTofu as a Terraform alternative for infrastructure management and Flux CD as a GitOps controller for Kubernetes. The program covers integration of both tools into a cohesive IaC + GitOps pipeline and production scenarios.

Why choose this training?

The Terraform license change and the growing popularity of GitOps are driving more organizations to seek fully open-source alternatives for infrastructure management and deployments. OpenTofu as a Terraform fork under the Linux Foundation umbrella and Flux CD as a native GitOps controller for Kubernetes provide the answer. This training shows how to effectively leverage both tools in a cohesive delivery pipeline.

Participants go through the full cycle — from managing infrastructure with OpenTofu, through implementing GitOps with Flux CD, to integrating both tools into a production pipeline. The program also covers production scenarios: disaster recovery, secrets management, and monitoring. Each module includes hands-on exercises on dedicated Kubernetes clusters.

The training is particularly valuable for DevOps engineers, platform engineers, and SREs who want to build or modernize their delivery pipeline using open-source tools. Whether you are migrating from Terraform or starting your IaC journey from scratch, the training delivers practical competencies ready for day-one application.

What makes our approach unique?

With over 2,500 trainings delivered and a network of more than 500 experts, EITT offers training led by practitioners who deploy OpenTofu and Flux CD in production environments daily. Our trainers understand both the strengths and limitations of each tool, enabling honest and practical knowledge transfer.

The training stands out through its emphasis on integration — rather than teaching each tool in isolation, we show how OpenTofu and Flux CD work together in a cohesive pipeline. Participants build a complete end-to-end solution, from infrastructure provisioning to application deployment, giving them a ready-to-use pattern for their own projects.
