typescript-docker-multi-stage-build

The purpose of this repository is to show how you can build a Docker image for a Node.js + TypeScript app with the Docker multi-stage feature, available since version 17.05.

Run the app

1. Install dependencies: npm install
2. Start the app: npm start
3. Call the greeting endpoint:

curl http://localhost:3000/greeting\?name\=John

{"id":"76ac792c-c1a9-4fc5-ba75-39652a06b381","message":"Hello, John!"}

Build the Docker image

To build the Docker image, use the docker build command:

docker build . -t greeting-service:latest

To stop the build on a specific stage, use the target option:

docker build --target builder -t greeting-service:latest .

Run the Docker image

To run the Docker image, use the docker run command:

docker run -p 3000:3000 --rm greeting-service:latest

Then, you can invoke the greeting service running in a Docker container with:

curl http://localhost:3000/greeting\?name\=Docker

{"id":"7af0385b-99dc-4d47-a423-f6ab18ea7f1c","message":"Hello, Docker!"}

typescript-docker-multi-stage-build's Issues

Container does not exit cleanly with SIGTERM because of running in PID 1

Should replace entry point with:
ENTRYPOINT [ "/sbin/tini", "-v", "-e", "143", "--", "node", "lib/server.js" ]
