What this course is
Where 'works on my machine' stops being a sentence.
Docker is the foundation of modern application delivery. Every cloud platform runs containers. Every modern CI/CD pipeline builds and ships images. Kubernetes is just orchestration of containers. Without Docker fluency, the rest of the modern stack is opaque.
At Nexperts, Docker is delivered as a 3-day intensive across 24 hours of live, hands-on lab time. We give you a real Docker host plus a small registry. By day 3 you've built 10+ images, run a multi-service Compose stack, hardened images for production and pushed signed images to a private registry.
Most engineers learn Docker by copying commands they don't understand. We work the other way — you understand the namespace and cgroup foundation first, and the commands click in 20 minutes.
We cover Docker, Docker Compose v2, Buildx, BuildKit, Docker Swarm-lite, and the path forward to Kubernetes (CKA / CKAD). We also cover Podman as an alternative — the RHEL standard.
Who should take this course
👨💻
Developers
Containerising the apps you build for cleaner local + CI/CD experience.
🐧
Sysadmins
Operations is moving to containers. This is the jump course.
☁️
Cloud engineers
ECS, ACI, GKE all run containers. This is the foundation under them.
📚
DevOps engineers
Pipelines build images. Images run in production. This is the daily-driver skill.
🔐
Security engineers
Container security is now a tier-1 discipline. This is the entry point.
📝
CKA / CKAD aspirants
K8s without Docker fluency is impossible. This is the prerequisite course.
Prerequisites
✓ Basic Linux command-line literacy (we recommend our Linux Admin course first)
✓ Comfortable with cd, ls, grep, vi / nano
✓ No prior containerisation experience required
✓ Basic networking (IP, ports, DNS)
→ If you can navigate a Linux server, you're ready.
Course Curriculum
Three days. From docker run to signed registries.
We cover Docker across 6 modules in 3 days. Every module is 70% hands-on against a live Docker host. By day 3 you have a multi-service production-grade stack running.
Hands-On Labs
8 labs. Build, run, ship.
Every lab runs on a live Docker host with a private registry. By day 3 you have a hardened production-grade multi-service stack.
01
Namespaces
Inspect Linux namespaces and cgroups of running containers.
Foundations
02
Multi-Service
Run a 3-container multi-service stack manually.
Daily-Driver
03
Volumes
Build persistent storage with volumes + bind mounts.
Daily-Driver
04
Multi-Stage
Build a Java + React app to a 35MB image.
Dockerfile
05
Compose Stack
Stand up a 6-service e-commerce stack with Compose.
95% of our Docker graduates ship a production stack on day 3.
Most Docker courses skip the namespace + cgroup foundation — the part that makes Docker click. We start there. By day 3, the entire toolchain feels coherent.

Why our pass rate is 95%
Self-study average: ~50% completion
Self-study Docker often plateaus at run + Dockerfile basics. Compose, image security and registries get skipped.
Nexperts: 95% capstone pass
We cover the full stack. By day 3 you have a hardened production-grade multi-service stack you can ship.
Your Container Path
Docker pairs with CKA and AWS.
Docker is the foundation. Stack with CKA / CKAD for Kubernetes, AWS / Azure for cloud-native, or DevOps tracks for end-to-end pipelines.
