CircleCI – Continuous Integration

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
• Job dependencies with requires keyword
• Approval jobs for manual deployment gates
• Scheduled workflows for nightly builds and maintenance

Module 4: Caching and Workspace

• Dependency caching: save_cache and restore_cache configuration
• Cache key strategies for maximum cache hit rates
• Workspaces: persisting data between jobs in a workflow
• Artifacts: storing and downloading build outputs

Module 5: CircleCI Orbs

• Orb overview: reusable pipeline components
• Using certified orbs: AWS, Kubernetes, and Slack orbs
• Writing custom orbs: commands, jobs, and executors
• Publishing and versioning custom orbs

Module 6: Testing and Code Quality

• Parallelising tests with test splitting
• Storing test results for insights and failure analysis
• Code coverage integration with CodeCov and SonarQube
• CircleCI Insights: pipeline performance and test analytics

Module 7: Deployment Pipelines

• Deploying to AWS, GCP, and Azure from CircleCI
• Kubernetes deployment with kubectl and Helm orbs
• Blue-green and canary deployment patterns in CircleCI
• Rollback strategies and deployment safeguards

Module 8: Capstone Project and Assessment

• Full CI/CD pipeline: test, build, and multi-environment deployment
• Custom orb development and publishing exercise
• Test parallelisation and pipeline optimisation project
• 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.
