Matrix Distribution
When to Use This Skill
Poor Fit
- Sequential operations where order matters
- Operations with shared state between targets
- When total job count would exceed GitHub Actions limits (256)
Implementation
Dynamic Matrix
Generate the target list in a discovery stage:
See examples.md for detailed code examples.
Failure Isolation
Prevent one failure from canceling other jobs:
strategy:
matrix:
target: ${{ fromJson(needs.discover.outputs.targets) }}
fail-fast: false # Critical: continue processing other targets
Rate Limiting
Control concurrency to avoid API rate limits:
strategy:
matrix:
target: ${{ fromJson(needs.discover.outputs.targets) }}
max-parallel: 10 # Limit concurrent jobs
Examples
See examples.md for code examples.
