Dart runtime Dockerfile

This repository contains Dockerfile of Dart runtime for Docker's automated build published to the public Docker Hub Registry.

This image is a base image that makes it easy to dockerize standard Dart application.

It can automatically bundle a Dart application with its dependencies and set the default command with no additional Dockerfile instructions.

This project heavily borrowed code from Google's google/dart-runtime Docker image.

Base Docker Image

• dockerfile/dart

Installation

1. Install Docker.

2. Download automated build from public Docker Hub Registry: docker pull dockerfile/dart-runtime

   (alternatively, you can build an image from Dockerfile: docker build -t="dockerfile/dart-runtime" github.com/dockerfile/dart-runtime)

Usage

This image assumes that your application:

• has a the pubspec.yaml and pubspec.lock files listing its dependencies.
• has a file named bin/server.dart as the entrypoint script.
• listens on port 8080.

When building your application docker image, ONBUILD triggers fetch the dependencies listed in pubspec.yaml and pubspec.yaml and cache them appropriatly using pub get.

• Step 1: Create a Dockerfile in your Dart application directory with the following content:

    FROM dockerfile/dart-runtime

• Step 2: Build your container image by running the following command in your application directory:

    docker build -t="app" .

• Step 3: Run application by mapping port 8080:

    APP=$(docker run -d -p 8080 app)
    PORT=$(docker port $APP 8080 | awk -F: '{print $2}')
    echo "Open http://localhost:$PORT/"
