A command line tool for building, testing & running your swift package in a docker container.
brew install iainsmith/formulae/swift-docker # Install swift docker
git clone https://github.com/jpsim/Yams.git # Clone an example package
cd Yams && swift test # Run the tests on your machine
swift docker test # Run the tests in a container
swift docker test --swift 5.1 # Check if the tests pass on swift 5.1
swift docker write-dockerfile # Write a ./Dockerfile to the repo- Test swift packages in one command
swift docker test - Use custom images -
swift docker test --image vapor/swift:latest -
swift docker build/test/runcommands mirrorswift build/test/run - Run your vapor application in a container -
swift docker vapor - Cached builds using docker volumes
- Use a mix of docker volumes & bind mounts for fast, small builds.
- Uses the swift docker image that matches the Package.swift manifest.
- Quickly free up space -
swift docker cleanup - Create a dockerfile for your project
- Quickly print a command to run the swift repl in the container -
swift docker repl - Create a .dockerignore file to avoid adding .git directory to the image
- Support multistage slim builds
- Log output to a file
- cmake build for running on Windows
Install with Homebrew
brew install iainsmith/formulae/swift-dockerInstall from source
> git clone https://github.com/iainsmith/swift-docker-cli.git > cd swift-docker > swift build -c release --disable-sandbox # copy the binary to somewhere in your path. > cp ./.build/release/swift-docker ~/bin
And install docker if you don't have it already
- Download the Docker Mac App.
- Or alternatively install via homebrew
brew cask install docker
OVERVIEW: A simple workflow for building & testing swift packages with docker
Run swift docker <subcommand> --help for subcommand details
Reference - Offical docker images: https://hub.docker.com/_/swift
Examples:
swift docker test
swift docker build -- --configuration release
swift docker run your-executable --flag1
swift docker vapor
USAGE: swift-docker <subcommand>
OPTIONS:
-h, --help Show help information.
SUBCOMMANDS:
build Build your swift package in a docker container.
test Test your swift package in a docker container.
run Run your swift package in a docker container.
vapor Run your vapor web application in a container.
build-image Build a docker image for your swift package.
repl print the command to run the swift repl in a container.
cleanup Remove temporary docker images.
write-dockerfile Write a dockerfile to disk.Run swift docker vapor to run your vapor application in a docker container. This is significantly faster than workflows that require you
to build a docker image as we bind the local directory into the container, and cache the build folder.
- You can pass custom arguments to your application by running
swift docker vapor -- arg1 --flag1. - Currently the environment is set to production & the port is set to 8080.
- The default docker image is
swift:latest. You can use a custom image withswift docker vapor --image vapor/swift:latest
Each docker image created by swift-docker is tagged with two labels.
LABEL com.swiftdockercli.action="test/build"
LABEL com.swiftdockercli.folder="your-project-name"
Running docker volume ls --filter label=com.swiftdockercli.action=test will list volumes created by swift-docker test.
