Best Docker Certifications in 2026 — DCA Is Gone, Here's What to Do Instead

The DCA Is Dead — Now What?

If you've searched for "Docker certification" recently, you've probably noticed the confusion. The Docker Certified Associate (DCA) — the only official Docker certification — was discontinued when Mirantis acquired Docker Enterprise. There is no direct replacement from Docker Inc. or Mirantis.

That leaves Docker as one of the most widely used technologies in the world with no official vendor certification. But that doesn't mean you can't prove your Docker skills. You just need to know where to look

Docker Certification Options in 2026

1. Cloud Provider Container Certifications

AWS, Google Cloud, and Azure all include Docker and container knowledge in their certifications, but none of them are Docker-specific:

• AWS Certified DevOps Engineer — covers ECS, ECR, and container deployment, but Docker is a small part of a much larger exam
• Google Cloud Professional Cloud DevOps Engineer — includes GKE and container concepts
• Azure Administrator (AZ-104) — touches on Azure Container Instances

The problem: these are cloud-specific exams that cost $150–$300, require extensive study beyond Docker, and test you on vendor lock-in services rather than core Docker skills.

2. Kubernetes Certifications (CKA/CKAD)

The CNCF's Certified Kubernetes Administrator (CKA) and Certified Kubernetes Application Developer (CKAD) are often recommended as Docker certification alternatives. They do cover container concepts, but:

• They focus on Kubernetes, not Docker
• They cost $395 each
• They assume you already know Docker — they don't test it directly
• Writing a Dockerfile and managing containers is very different from managing Kubernetes clusters

3. Linux Foundation Certified IT Associate (LFCA)

The LFCA includes a "DevOps Fundamentals" section that covers container basics. But at $250 and with Docker being just one of many topics, it's not a Docker credential — it's a general IT certification that happens to mention containers.

4. TrueCert Docker Track

TrueCert offers a progressive Docker certification path:

Level	Certification	Questions	Time	Price
Introduction	Docker Introduction	10	10 min	Free
Fundamentals	Docker Fundamentals	20	30 min	$14.99
Professional	Docker Professional	25	50 min	$29.99

What's covered:

• Introduction — containers vs VMs, basic commands, images, Dockerfiles
• Fundamentals — Dockerfile instructions, container lifecycle, images and containers, Docker Compose, volumes and storage, Docker networking
• Professional — multi-stage builds, container security (scanning, rootless, read-only), registry management, advanced Compose (profiles, healthchecks), resource limits, overlay networking, logging and monitoring, production deployment patterns

All assessments are timed, randomized from a question bank, and produce verifiable Open Badges 2.0 certificates.

Which Should You Choose?

Choose CKA if you're focused on Kubernetes and already know Docker well. The CKA assumes Docker knowledge — it doesn't teach or test it.

Choose a cloud cert if you need to prove skills on a specific platform (AWS, GCP, Azure) and containers are just part of that picture.

Choose TrueCert if:

• You want to verify your Docker skills specifically, not as a side topic in a broader exam
• You don't want to spend $195–$395 on a certification that barely covers Docker
• You want to start free and progress through levels
• You need instant results and a verifiable credential

The Practical Approach

Here's what we'd recommend:

Step 1: Take the free Docker Introduction on TrueCert. 10 minutes, zero risk. See if you actually know the basics or just think you do.

Step 2: If you pass, move to Docker Fundamentals. This covers the core skills you use daily — Dockerfiles, Compose, networking, volumes. 20 questions, 30 minutes, $14.99.

Step 3: For engineers who manage containers in production, Docker Professional covers multi-stage builds, security scanning, registry management, and production deployment patterns — the skills that separate someone who uses Docker from someone who runs it in production.

Step 4: If your role also involves orchestration, pair your Docker credentials with the Kubernetes track. Container skills and orchestration skills complement each other — Docker is how you build and run containers, Kubernetes is how you manage them at scale.

The Bottom Line

The DCA is gone and nothing has directly replaced it. Cloud certs and Kubernetes certs include containers as a subtopic, but none of them actually verify that you can write a Dockerfile, debug a container, configure networking, or secure a production deployment.

Docker skills aren't going away — containers are the foundation of modern deployment. The certification landscape just hasn't caught up. TrueCert fills that gap with Docker-specific assessments at every level, starting free.
