Design CI workflows to prevent resource conflicts when multiple builds run concurrently on shared infrastructure. This includes using unique identifiers for temporary resources, minimizing container privileges, and separating CI-specific operations from local development workflows.
Key practices:
Example of problematic code:
TMP_CONTAINER="tmpcontainer" # Fixed name causes conflicts
docker run --privileged ... # Unnecessary privileges
Better approach:
TMP_CONTAINER="tmpcontainer-$(date +%s)-$$" # Unique per run
docker run ... # Only add --privileged if actually needed
This prevents build failures when multiple PRs or builds execute simultaneously on shared CI infrastructure, and ensures local development workflows remain usable without requiring system-level permissions.
