DevOps engineering has become one of the most in-demand technical disciplines of the decade, bridging software development and infrastructure operations through automation, containerization, and continuous delivery pipelines. CertLabz offers a complete catalogue of free, blockchain-verified DevOps certificates covering the full toolchain: Docker, Kubernetes, GitHub Actions, Terraform, Ansible, Prometheus, Grafana, and Linux. Every CertLabz certificate is earned through hands-on browser labs and a SkillTracker exam, and every certificate ships with a unique blockchain verification URL plus CPE credit hours that count toward renewals for AWS, Microsoft, Cisco, and CompTIA credentials. This guide ranks the CertLabz DevOps certificates worth earning in 2025 and maps a clear path from your first course cert to a full-stack DevOps Engineer Skill Track.

Free CertLabz DevOps Certificates in 2025
DevOps Engineer Skill Track
The flagship CertLabz DevOps credential. Ten lab modules and 30 hands-on labs walk you through the full delivery lifecycle: Git workflows, Docker, Kubernetes, GitHub Actions and GitLab CI pipelines, Terraform infrastructure as code, Ansible configuration, and Prometheus and Grafana observability. Finish the SkillTracker exam to earn a free blockchain-verified certificate worth up to 13 CPE credits.
Site Reliability Engineering Skill Track
Built around real SRE practice: SLIs, SLOs, error budgets, blameless postmortems, on-call rotations, capacity planning, and incident response. Ten lab modules and 30 hands-on labs cover golden-signal monitoring, alerting strategy, runbook automation, and chaos engineering. Awards a free blockchain-verified certificate worth 11.5 to 13 CPE credits on completion of the SkillTracker exam.
Kubernetes Fundamentals Course
A focused course certificate covering Kubernetes architecture, pods, deployments, services, ConfigMaps, secrets, ingress, and basic cluster operations. Browser-based interactive labs spin up a real cluster you can break and rebuild. Awards a free blockchain-verified course certificate of completion that maps cleanly into the DevOps Engineer Skill Track when you are ready to go deeper.
Docker Fundamentals Course
The fastest on-ramp into the CertLabz DevOps catalogue. Covers containerization fundamentals, Dockerfile authoring, Docker Compose for multi-container applications, networking, and volumes through hands-on browser labs. Completing the course awards a free blockchain-verified certificate of completion. Essential knowledge for any DevOps or platform engineering role in 2025.
Terraform & IaC Course
Hands-on Terraform from the ground up: providers, resources, variables, state management, modules, workspaces, and remote backends. Browser sandboxes provision and destroy real infrastructure so you build practical IaC muscle memory, not slide-deck theory. Completing the course awards a free blockchain-verified certificate that pairs with the DevOps Engineer Skill Track.
GitHub Actions and GitLab CI Course
A side-by-side course on the two most widely used CI/CD platforms. You build pipelines for automated testing, container image builds, environment secrets, matrix builds, and multi-stage deployments using both GitHub Actions and GitLab CI. The free blockchain-verified certificate of completion proves you can ship a production pipeline, not just describe one.
Cloud Engineer Skill Track
Vendor-neutral cloud foundations across AWS, Azure, and GCP: identity, networking, compute, storage, managed databases, and serverless. Ten lab modules and 30 hands-on labs build the cloud literacy every DevOps engineer needs before specialising. Awards a free blockchain-verified certificate worth up to 13 CPE credits and pairs naturally with the DevOps Engineer Skill Track.
Ansible Automation Course
Configuration management and infrastructure automation with Ansible: inventories, playbooks, roles, handlers, vault, and idempotent task design. Hands-on labs target real Linux fleets so you practise rolling changes safely. Completing the course awards a free blockchain-verified certificate of completion and counts toward the DevOps Engineer Skill Track requirements.
Linux Administration Course
The Linux fluency every DevOps engineer needs: shell, permissions, systemd, networking, package management, log analysis, and shell scripting. Browser terminals drop you into a real distribution from minute one. Awards a free blockchain-verified certificate of completion and cross-links to CertLabz CompTIA Linux+ exam prep when you are ready for a vendor-neutral exam-aligned credential.
Observability with Prometheus & Grafana
End-to-end observability: metrics with Prometheus, dashboards with Grafana, alerting rules, log pipelines, and the four golden signals. Hands-on labs instrument a sample microservice so you graduate able to diagnose a real production incident. Awards a free blockchain-verified certificate of completion and complements the SRE Skill Track.
