Module 1: Introduction to CircleCI

• CircleCI overview: cloud-native CI/CD platform
• CircleCI architecture: executors, workflows, and orbs
• CircleCI Cloud vs CircleCI Server deployment options
• Navigating the CircleCI dashboard: pipelines, workflows, and jobs

Module 2: CircleCI Configuration Fundamentals

• config.yml structure: version, jobs, workflows, and executors
• Executor types: Docker, machine, macOS, and Windows
• Steps: checkout, run, save_cache, restore_cache, and store_artifacts
• Environment variables: project, context, and built-in variables

Module 3: Workflows and Job Orchestration

• Sequential and parallel workflow design

• Final assessment and course certification

Experience in the Industry Gain expertise from CircleCI practitioners who have built high-performance CI/CD pipelines for SaaS companies, mobile app teams, and cloud-native engineering organisations using CircleCI Cloud and Server.

Backgrounds at the Top Our CircleCI trainers have worked at technology companies and DevOps consultancies delivering fast, reliable software releases with CircleCI as the core continuous integration and delivery platform.

Clear & Effective Teaching CircleCI config.yml, executors, workflows, caching, orbs, test parallelisation, and deployment pipelines are explained with practical software delivery scenarios and real pipeline configuration examples.

Hands-On Learning Focus Students build CircleCI pipelines, write custom orbs, parallelise tests, configure deployment workflows, and optimise pipeline performance through structured hands-on lab exercises.

Up-to-Date Knowledge Trainers keep content current with the latest CircleCI platform releases, CircleCI runner updates, dynamic configuration features, and evolving CI/CD pipeline optimisation best practices.
