GitHub Actions Optimization Techniques
While multiple production deployments in a day is routine for many companies, there are still teams that struggle with building bulk dependencies that take the build times forever.
This is for them..
1. Speed Up Your Workflows with Caching:
Just by implementing cache in a sample project,
I reduced build time from 5m 29s to 2m 12s - A whopping 60%.
And the installation of dependencies time reduced from 5m 17s to 1m 38s - A 69% improvement.
We all know, Caching allows you to save dependencies and other commonly used data between workflow runs, significantly cutting down the time needed for repeated tasks.
Instead of doing this:
Install build essentials
Install dependencies
Run application script
Do this:
Install build essentials
Cache dependencies
Install dependencies
Run application script
GitHub Actions snippet without Caching:
- name: Install build essentials
run: sudo apt-get update && sudo apt-get install -y python3-distutils python3-dev build-essential
- name: Install dependencies
run: |
python -m pip install --upgrade pip
pip install -r requirements.txt
- name: Run Python script
run: |
python main.pyGitHub Actions Config with Caching:
- name: Install build essentials
run: sudo apt-get update && sudo apt-get install -y python3-distutils python3-dev build-essential
- name: Cache dependencies
uses: actions/cache@v4
with:
path: ~/.cache/pip
key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
restore-keys: |
${{ runner.os }}-pip-
- name: Install dependencies
run: |
python -m pip install --upgrade pip
pip install -r requirements.txt
- name: Run Python script
run: |
python main.pyThe above example is for pip. Adjust the path and key according to your project's dependency management (e.g., ~/.m2 for Maven, ~/.gradle for Gradle).
2. Simplify Workflow Management with Reusable Workflows:
Reusable workflows enable you to consolidate shared processes, making them easily applicable across multiple workflows. This approach minimizes repetition and boosts the overall maintainability of your workflow configurations.
An example:
# .github/workflows/reusable-workflow.yaml
name: Reusable Workflow
on: workflow_call
jobs:
reusable-job:
runs-on: ubuntu-latest
steps:
- name: Print message
run: echo "Reusable workflow executed"You can now call this workflow from any other workflow within your repository.
name: Use Reusable Workflow
on: [push]
jobs:
execute-reusable:
uses: your-org/repo/.github/workflows/reusable-workflow.yaml@mainThese are very simple to understand and implement.
Remember, often the most simple solutions do great magic. We just overlook them.
