> Diagnose build timeouts, missing lockfiles, or compilation errors.

- **Category**: Troubleshoot
- **Last Verified**: 2026-07-14

## Symptom

Build fails with error code `DOCKERFILE_BUILD_FAILED` or `DEPENDENCY_INSTALL_FAILED`.

## What it means

The compilation worker failed to build your code layers.

## Most likely causes

- Missing dependency files (e.g. `package-lock.json` or `go.sum`).
- Syntax errors in compilation steps or tests.
- Build exceeded the 20-minute execution limit.

## How to diagnose it

Stream the build logs to read compiler standard output:

```bash
kubeletto logs my-service --build
```
