GitHub Actions has revolutionized the way developers automate workflows. While the platform is powerful on its own, the ability to use parameters and manual triggers can take your automation game to the next level. In this blog, we’ll explore how to create workflows with parameters and manually trigger them for greater control and flexibility.
Introduction to GitHub Actions
GitHub Actions is a CI/CD platform integrated directly into GitHub, allowing you to automate tasks like testing, building, and deploying code. It uses workflows defined in YAML files to automate these tasks based on triggers such as push events, pull requests, or scheduled times.
Understanding Workflow Parameters
Parameters in GitHub Actions provide a way to make your workflows more dynamic and flexible. They allow you to pass in different values for various parts of the workflow, such as environment variables, paths, or commands.
Example of a Simple Workflow with Parameters:
name: Deploy
on:
workflow_dispatch:
inputs:
environment:
description: 'Deployment Environment'
required: true
default: 'production'
type: string
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Deploy to environment
run: |
echo "Deploying to ${{ github.event.inputs.environment }}"
In this example, the workflow_dispatch trigger allows the workflow to be manually triggered from the GitHub Actions UI. The environment input parameter can be used to specify where the code should be deployed (e.g., production, staging).
Manual Triggers with
workflow_dispatch
Manual triggers give developers the ability to run workflows on-demand rather than automatically based on events like pushes or pull requests. This is useful in situations where you want to control exactly when a workflow runs, such as deploying a new release or performing maintenance tasks.
To enable manual triggers, use the workflow_dispatch event in your YAML file. You can also define inputs that allow the person triggering the workflow to customize its behavior.
Setting Up a Workflow with Manual Triggers:
name: Run Tests
on:
workflow_dispatch:
inputs:
test_suite:
description: 'Select Test Suite'
required: true
default: 'all'
type: choice
options:
- unit
- integration
- e2e
- all
jobs:
test:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Run selected test suite
run: |
echo "Running ${{ github.event.inputs.test_suite }} tests"
In this workflow, a user can manually trigger the tests and select which test suite to run: unit tests, integration tests, end-to-end (e2e) tests, or all of them.
Advanced Use Cases
1. Conditional Deployments: You can combine parameters with conditions to deploy to different environments based on user input.
- name: Deploy to Environment
if: ${{ github.event.inputs.environment == 'production' }}
run: echo "Deploying to Production"v
2. Dynamic Configuration: Use parameters to dynamically configure your workflow based on the needs of your project.
- name: Build with Parameters
run: |
echo "Building project with configuration: ${{ github.event.inputs.configuration }}"
Benefits of Using Parameters and Manual Triggers
Flexibility: Adapt your workflows to different environments, configurations, or scenarios without modifying the YAML file each time.
Control: Manually trigger workflows when you’re ready, rather than relying on automated triggers that may not always be ideal.
User-Friendly: Easily interact with your workflows through the GitHub UI, making it simple to deploy, test, or build your projects.
