What is Dart?

Dart is an approachable, portable, and productive language for high-quality apps on any platform.

Its goal is to offer the most productive programming language for multi-platform development, paired with a flexible execution runtime platform for app frameworks, and support for full-stack development. For more details, see [***]

By utilizing Dart's support for ahead-of-time (AOT) compilation to executables, you can create very small runtime images (~10 MB).

Using this image

We recommend using small runtime images that leverage Dart's support for ahead-of-time (AOT) compilation to executables. This enables creating small runtime images (~10 MB).

Creating a Dart server app

After installing the Dart SDK, version 2.14 or later, use the dart command to create a new server app:

shell
$ dart create -t server-shelf myserver

Running the server with Docker Desktop

If you have Docker Desktop installed, you can build and run on your machine with the docker command:

shell
$ docker build -t dart-server .
$ docker run -it --rm -p 8080:8080 --name myserver dart-server

When finished, you can stop the container using the name you provided:

shell
$ docker kill myserver

Image documentation

Dockerfile

The Dockerfile created by the dart tool performs two steps:

1. Using the Dart SDK in the dart:stable image, compiles your server (bin/server.dart) to an executable (server).

2. Assembles the runtime image by combining the compiled server with the Dart VM runtime and it's needed dependencies located in /runtime/.

Dockerfile
# Specify the Dart SDK base image version using dart:<version> (ex: dart:3.10)
FROM dart:stable AS build

# Resolve app dependencies.
WORKDIR /app
COPY pubspec.* ./
RUN dart pub get

# Copy app source code and AOT compile it.
COPY . .
# Ensure packages are still up-to-date if anything has changed
RUN dart pub get --offline
RUN dart build cli --target bin/server.dart -o output

# Build minimal serving image from AOT-compiled `/server` and required system
# libraries and configuration files stored in `/runtime/` from the build stage.
FROM scratch
COPY --from=build /runtime/ /
COPY --from=build /app/output/bundle/ /app/

# Start server.
EXPOSE 8080
CMD ["/app/bin/server"]

.dockerignore

Additionally it creates a recommended .dockerignore file, which enumarates files that should be omitted from the built Docker image:

text
.dockerignore
Dockerfile
build/
.dart_tool/
.git/
.github/
.gitignore
.packages
