Duration 4 days – 28 hrs
Overview
This 4-day hands-on course introduces developers and technical practitioners to Linux containers using Podman, then bridges those skills into Kubernetes and Red Hat OpenShift (OCP v4.18). Participants learn core container concepts, build and manage images, persist data, troubleshoot containerized workloads, compose multi-container applications, and deploy containerized apps to OpenShift using foundational orchestration concepts.
Objectives
- Explain container fundamentals and how containers differ from traditional deployment models
- Use Podman to run, inspect, access, network, and manage containers end-to-end
- Work with container registries and manage container images effectively
- Build custom container images using Containerfiles, including advanced instructions
- Apply rootless Podman concepts for improved security and developer workflows
- Persist application data using volume mounting and basic database container patterns
- Troubleshoot container issues using logs and debugging approaches
- Build and run multi-container applications using Compose for developer environments
- Deploy and run containerized applications on OpenShift/Kubernetes, including multi-pod apps
- Consolidate learning through a comprehensive review lab
Audience
- Application developers transitioning to container-based development
- DevOps engineers and build/release engineers supporting container pipelines
- SRE/Platform engineers who need container fundamentals before OpenShift operations
- QA/Automation engineers working with containerized test environments
- Technical leads evaluating containerization and OpenShift adoption
Pre-requisites
- Basic Linux command-line skills (files, permissions, editors, processes)
- Familiarity with application runtime concepts (services, ports, environment variables)
- Basic understanding of networking concepts (IP, DNS, ports)
- Optional but helpful: basic Git and CI/CD exposure
