From 94c19282fed99ba905c98c88bdbf4babb43833a1 Mon Sep 17 00:00:00 2001 From: Kevin Wittek Date: Fri, 15 Aug 2025 13:53:22 +0200 Subject: [PATCH 1/3] feat: integrate Docker Compose with individual service files and add CI smoke tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove run.sh script and .env file - Update README.md to use Docker Compose directly - Replace root docker-compose.yml with include directive - Add individual docker-compose.yml files for each service - Configure consistent port mapping (8080 internal, 8080-8083 external) - Update all services to use LLAMA_URL/LLAMA_MODEL env vars only - Add health endpoint to Node.js service - Add GitHub Actions workflow with Docker Model Plugin integration - Remove dotenv dependency from Node.js project BREAKING CHANGE: services now require Docker Model Runner instead of .env file 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .env | 5 -- .github/workflows/smoke-tests.yml | 136 ++++++++++++++++++++++++++++++ README.md | 4 +- docker-compose.yml | 92 ++------------------ go-genai/docker-compose.yml | 22 +++++ go-genai/main.go | 18 ++-- node-genai/app.js | 36 +++----- node-genai/docker-compose.yml | 22 +++++ node-genai/package.json | 1 - py-genai/app.py | 24 +++--- py-genai/docker-compose.yml | 23 +++++ run.sh | 20 ----- rust-genai/docker-compose.yaml | 16 +++- rust-genai/src/config.rs | 9 +- 14 files changed, 266 insertions(+), 162 deletions(-) delete mode 100644 .env create mode 100644 .github/workflows/smoke-tests.yml create mode 100644 go-genai/docker-compose.yml create mode 100644 node-genai/docker-compose.yml create mode 100644 py-genai/docker-compose.yml delete mode 100755 run.sh diff --git a/.env b/.env deleted file mode 100644 index 0f321546..00000000 --- a/.env +++ /dev/null @@ -1,5 +0,0 @@ -# Configuration for the LLM service -LLM_BASE_URL=http://model-runner.docker.internal/engines/llama.cpp/v1 - -# Configuration for the model to use -LLM_MODEL_NAME=ai/llama3.2:1B-Q8_0 \ No newline at end of file diff --git a/.github/workflows/smoke-tests.yml b/.github/workflows/smoke-tests.yml new file mode 100644 index 00000000..bb113404 --- /dev/null +++ b/.github/workflows/smoke-tests.yml @@ -0,0 +1,136 @@ +name: Smoke Tests + +on: + push: + branches: [ main, update-compose-integration ] + pull_request: + branches: [ main ] + +jobs: + smoke-test: + runs-on: ubuntu-latest + + strategy: + matrix: + project: [go-genai, py-genai, node-genai, rust-genai] + + steps: + - name: Checkout code + uses: actions/checkout@v4 + + - name: Set up Docker Buildx + uses: docker/setup-buildx-action@v3 + + - name: Install Docker Model Plugin + run: | + # Add Docker's official GPG key + sudo apt-get update + sudo apt-get install ca-certificates curl + sudo install -m 0755 -d /etc/apt/keyrings + sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc + sudo chmod a+r /etc/apt/keyrings/docker.asc + + # Add the repository to Apt sources + echo \ + "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \ + $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \ + sudo tee /etc/apt/sources.list.d/docker.list > /dev/null + sudo apt-get update + + # Install docker-model-plugin + sudo apt-get install -y docker-model-plugin + + # Verify installation + if sudo docker model version;
