From ffd8a8b6e07c52ef79b0e1b98d22a7430b6615aa Mon Sep 17 00:00:00 2001 From: Adam Banky Date: Sun, 11 Jan 2026 16:27:39 +0100 Subject: [PATCH 1/3] fix(runtime): sanitize project names for Docker Compose compatibility Docker Compose requires project names to consist only of lowercase alphanumeric characters, hyphens, and underscores. Projects with periods (e.g., 'tektonio.app') would fail with an error. Changes: - Added sanitize_docker_project_name() function to convert invalid names - Applied sanitization to COMPOSE_PROJECT_NAME environment variable - Added validation during 'weft init' with interactive prompt - Added 11 unit tests + 1 integration test (100% coverage) - Updated troubleshooting.md with Docker Compose name requirements - Updated cli-reference.md to document naming constraints The sanitization: - Converts to lowercase - Replaces invalid characters with hyphens - Removes leading/trailing hyphens/underscores - Provides fallback for edge cases Fixes issue where 'weft up' would fail with: "invalid project name: must consist only of lowercase alphanumeric characters, hyphens, and underscores" --- docs/cli-reference.md | 2 +- docs/troubleshooting.md | 34 +++++++- src/weft/cli/init.py | 21 +++++ src/weft/cli/runtime/helpers.py | 43 ++++++++- tests/unit/weft/cli/test_runtime.py | 130 +++++++++++++++++++++++++++- 5 files changed, 226 insertions(+), 4 deletions(-) diff --git a/docs/cli-reference.md b/docs/cli-reference.md index 617b983..5ab8ffd 100644 --- a/docs/cli-reference.md +++ b/docs/cli-reference.md @@ -44,7 +44,7 @@ weft init [OPTIONS] | Flag | Type | Description | |---------------------------|---------|---------------------------| -| `--project-name TEXT` | String | Project name | +| `--project-name TEXT` | String | Project name (lowercase letters, numbers, hyphens, and underscores only) | | `--project-type CHOICE` | Choice | `backend` \| `frontend` \| `fullstack` | | `--ai-provider CHOICE` | Choice | `claude` \| `ollama` \| `other` | | `--ai-history-path PATH` | Path | AI history repo path | diff --git a/docs/troubleshooting.md b/docs/troubleshooting.md index ee1b1ee..8e7e456 100644 --- a/docs/troubleshooting.md +++ b/docs/troubleshooting.md @@ -129,7 +129,7 @@ Log out and back in for changes to apply. ### Containers fail to start -**Problem** +**Problem** Agent containers exit immediately. **Fix** @@ -142,6 +142,38 @@ Most commonly caused by missing API keys or Docker misconfiguration. --- +### Invalid project name for Docker Compose + +**Problem** +Docker Compose reports: "invalid project name... must consist only of lowercase alphanumeric characters, hyphens, and underscores" + +**Fix** + +Project names with periods (like `my.app` or `company.com`) are not supported by Docker Compose. + +**Option 1: Use a valid name during init** +```bash +weft init --project-name my-app # Use hyphens instead of periods +``` + +**Option 2: Update existing project** +Edit `.weftrc.yaml` and change the project name: +```yaml +project: + name: my-app # Changed from my.app + type: fullstack +``` + +Then restart the runtime: +```bash +weft down +weft up +``` + +**Note:** Weft will automatically sanitize invalid project names for Docker Compose internally.
