From d11df78d1fc37e45e1e3295664acf5db559f97cc Mon Sep 17 00:00:00 2001 From: Yaojia Wang Date: Tue, 4 Nov 2025 23:25:22 +0100 Subject: [PATCH] fix(backend): Fix Dockerfile and add health check endpoint for Docker MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes the backend Docker configuration to enable one-click backend startup for frontend developers. Changes: - Updated Dockerfile with correct paths for modular monolith architecture * Added all module projects (Identity, ProjectManagement, IssueManagement) * Optimized layer caching by copying .csproj files first * Used alpine runtime image for smaller size (~500MB reduction) * Added non-root user (appuser) for security * Simplified to single HTTP port (8080) for development - Enhanced .dockerignore to optimize build context * Excluded unnecessary files (docs, git, docker files) * Added environment and secret file exclusions - Added /health endpoint to Program.cs * Required for Docker HEALTHCHECK functionality * Enables docker-compose to verify backend is ready Testing: - Docker build succeeds in ~14 seconds (after first build) - Backend container starts and passes health check - Swagger UI accessible at http://localhost:5000/scalar/v1 - Health endpoint returns "Healthy" at http://localhost:5000/health This implements Phase 1 of DOCKER-DEVELOPMENT-ENVIRONMENT.md 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- colaflow-api/.dockerignore | 67 +++++++++++++---- colaflow-api/Dockerfile | 91 ++++++++++++++++++------ colaflow-api/src/ColaFlow.API/Program.cs | 6 ++ 3 files changed, 128 insertions(+), 36 deletions(-) diff --git a/colaflow-api/.dockerignore b/colaflow-api/.dockerignore index 7712b39..a867529 100644 --- a/colaflow-api/.dockerignore +++ b/colaflow-api/.dockerignore @@ -1,18 +1,11 @@ #
