From 20b53bd4b86020a7390c0640d97440bbf91c0ca0 Mon Sep 17 00:00:00 2001 From: Ryan Clark Date: Thu, 26 Jun 2025 12:18:32 -0700 Subject: [PATCH] feat: add BetterUp deployment infrastructure for Langflow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive Kubernetes deployment and CI/CD setup for deploying Langflow in BetterUp infrastructure. ## πŸš€ Kubernetes Deployment - **Helm Chart**: Complete chart with Deployment, Service, HPA, PDB, Secrets - **Security**: Non-root containers, security contexts, resource limits - **Scaling**: Horizontal Pod Autoscaler with CPU-based scaling - **Health Checks**: Liveness and readiness probes for reliability - **Environment Values**: Dev-specific configuration with staging/prod ready ## πŸ”„ CI/CD Pipeline - **Build Workflow**: Docker image build and push to ECR - **Deployment Pipeline**: Helm chart packaging and Kubernetes deployment - **Test Suite**: Python tests and Docker build validation - **Environment Promotion**: Automated dev/staging, manual production ## 🐳 Production Container - **Multi-stage Build**: Optimized for security and size - **PostgreSQL Ready**: Built-in database connectivity with langflow[postgresql] - **Security**: Non-root user (1000:1000), minimal attack surface - **Health Checks**: Built-in HTTP health endpoint monitoring ## πŸ—οΈ Infrastructure Integration - **ECR**: Container registry for betterup-langflow-us-east-1 - **EKS**: Kubernetes deployment with proper service accounts - **RDS**: PostgreSQL database (managed via betterup-infrastructure) - **IAM**: Service account with AWS role integration - **Secrets**: Database credentials via AWS Secrets Manager ## πŸ“ Repository Changes - Add `release/kubernetes/langflow/` - Complete Helm chart - Add `.github/workflows/` - CI/CD workflows following BetterUp patterns - Add `Dockerfile.production` - Production-optimized container - Add `DEPLOYMENT.md` - Comprehensive deployment documentation - Remove `docker_example/` - Replaced with production setup ## πŸ”§ Environment Support - **Dev (us-east-1-dev)**: Single replica, reduced resources, debug logging - **Staging**: Multi-replica, production-like setup (future) - **Production**: High-availability configuration (future) ## πŸ“š Documentation - **DEPLOYMENT.md**: Complete deployment guide with troubleshooting - **Architecture Diagrams**: GitOps workflow and component overview - **Environment Configuration**: Detailed setup for each environment ## ⚑ Next Steps 1. Deploy infrastructure from betterup-infrastructure PR #3373 2. Create ECR repository and configure IAM roles 3. Set up GitHub Actions secrets and environments 4. Test deployment pipeline in dev environment This follows established BetterUp patterns from identity-service and lighthouse deployments. πŸ€– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../build_and_push_staging_image.yml | 60 ++++++ .../deploy_us_east_1_staging_chart.yml | 47 +++++ .../push_us_east_1_staging_chart.yml | 47 +++++ .github/workflows/staging_cd.yml | 26 +++ .github/workflows/test.yml | 52 +++++ DEPLOYMENT.md | 192 ++++++++++++++++++ Dockerfile.production | 46 +++++ README.md | 82 ++++---- docker_example/Dockerfile | 3 -

It depends on the `postgres` service. - -Environment variables: - -- `LANGFLOW_DATABASE_URL`: The connection string for the PostgreSQL database. -- `LANGFLOW_CONFIG_DIR`: The directory where LangFlow stores logs, file storage, monitor data, and secret keys. - -Volumes: - -- `langflow-data`: This volume is mapped to `/app/langflow` in the container. - -### PostgreSQL Service - -The `postgres` service uses the `postgres:16` Docker image and exposes port 5432. - -Environment variables: - -- `POSTGRES_USER`: The username for the PostgreSQL database. -- `POSTGRES_PASSWORD`: The password for the PostgreSQL database. -- `POSTGRES_DB`: The name of the PostgreSQL database. - -Volumes: - -- `langflow-postgres`: This volume is mapped to `/var/lib/postgresql/data` in the container. - -## Switching to a Specific LangFlow Version - -If you want to use a specific version of LangFlow, you can modify the `image` field under the `langflow` service in the Docker Compose file. For example, to use version 1.0-alpha, change `langflowai/langflow:latest` to `langflowai/langflow:1.0-alpha`. diff --git a/docker_example/docker-compose.yml b/docker_example/docker-compose.yml deleted file mode 100644 index 10c8bdfdc584..000000000000 --- a/docker_example/docker-compose.yml +++ /dev/null @@ -1,29 +0,0 @@ -services: -
