Docker¶

Build, ship, and run applications in containers — from your first docker run to production-ready images, Compose stacks, and CI/CD integration.

Overview¶

The REBASH Academy Docker track is a structured, 20-tutorial curriculum for developers and DevOps engineers. Containers power modern delivery: local dev parity, CI pipelines, and the foundation of Kubernetes. Each tutorial follows our documentation standards with theory, hands-on labs, commands, best practices, and interview questions.

Learning Path

Complete Linux, Networking, and Git first — Docker builds directly on those skills.

Learning Objectives¶

After completing this track, you will be able to:

Explain containers vs VMs and run Docker on Linux
Build optimized images with Dockerfile and multi-stage builds
Manage data with volumes and orchestrate stacks with Compose
Configure container networking and push to registries
Secure, monitor, and troubleshoot containers in production
Integrate Docker into CI/CD and transition toward Kubernetes

Who Is This For?¶

Audience	Benefit
Developers	Consistent local dev and deployable artifacts
DevOps / SRE	Containerize services and pipeline images
Students	Job-ready Docker for interviews and labs
Cloud engineers	Foundation before Kubernetes

Linux — cgroups, namespaces, and CLI tools
Networking — bridges, ports, and DNS
Git — version Dockerfiles and Compose files
Kubernetes — next step after this track
