Lights, Camera, GitHub Actions!

We refactored a complex 244-line CI/CD workflow into a clean 74-line reusable pipeline. This session shows you how.

Lights, Camera, GitHub Actions!
#1about 3 minutes

Understanding the core components of GitHub Actions

A workflow is triggered by an event and contains jobs with steps that run on hosted or self-hosted runners.

#2about 7 minutes

Configuring workflow triggers with events and filters

Workflows can be triggered by repository events, schedules, or manual dispatches, with filters for branches, tags, and paths to control execution.

#3about 10 minutes

Sharing data between jobs with contexts and variables

Use contexts, environment variables, inputs, and outputs to pass information between different jobs and steps in a workflow.

#4about 6 minutes

Managing job dependencies and concurrency

Control the execution order of jobs using the `needs` keyword and manage parallel runs with concurrency groups to prevent race conditions.

#5about 4 minutes

Creating modular pipelines with reusable workflows

Avoid duplicating code by creating reusable workflows that can be called from other workflows, passing secrets and inputs as needed.

#6about 6 minutes

Demoing manual inputs and job dependency results

A practical demonstration shows how to use different input types for manual triggers and how job dependencies affect skipped or failed jobs.

#7about 13 minutes

Refactoring a repetitive Java build with reusable workflows

A complex multi-OS Java build workflow is refactored into a cleaner, maintainable pipeline by extracting common logic into a reusable workflow.

#8about 15 minutes

Answering audience questions on GitHub Actions

The speaker answers questions about comparing GitHub Actions to other CI/CD tools, optimizing performance, and its future evolution.
