Platform.sh Build Failed: Troubleshooting Guide
A failed build on Platform.sh can be frustrating, but understanding the common causes and how to diagnose them can significantly reduce downtime. This guide provides practical steps to identify and fix build failures.
Understanding Build Logs
The first step in resolving a build failure is analyzing the build logs. These logs contain valuable information about the build process, including any errors or warnings encountered. You can access them through the Platform.sh CLI or the web interface.
- Access the Logs: Use the command
platform logsin your terminal, or navigate to your project in the Platform.sh console and select "Activity". Find the failed build and view its logs. - Identify the Error: Look for error messages (often highlighted in red or marked with "ERROR") and trace them back to their origin. Pay attention to the timestamps to understand the sequence of events.
- Analyze Dependencies: Check for dependency installation errors. These often manifest as "package not found" or "dependency conflict" messages.
Common Causes and Solutions
Dependency Issues
One of the most frequent causes of build failures is related to dependency management. This can stem from incorrect versions specified in your configuration files (e.g., composer.json, package.json, requirements.txt) or problems with the package repositories themselves.
- Incorrect Versions: Double-check that your dependency versions are compatible with your application and the Platform.sh environment. Use version constraints (e.g.,
^7.4for PHP) to allow for minor updates. - Repository Issues: Occasionally, package repositories (like Packagist or npm) may experience temporary outages. Retry the build a few minutes later, or consider using a package proxy.
- Missing Dependencies: Ensure all required dependencies are listed in your configuration files. Use the correct syntax and spelling for each package. For example, a missing PHP extension listed in `.platform.app.yaml` can cause a build failure.
Configuration Errors
Misconfigured services or application settings can also lead to build failures. Review your .platform.app.yaml, .platform/services.yaml, and other configuration files for errors. Pay close attention to syntax and ensure all required fields are present and correctly formatted.
Resource Limits
Build processes have resource limits (e.g., memory, CPU time). Exceeding these limits can cause the build to fail. Optimize your build process to reduce resource consumption, or contact Platform.sh support to request higher limits.
