Docker image for building React Native Android apps

This Docker image contains all dependencies required to build Android apps based on React Native and ensures that build happens in the clear environment.

Building the image

You can rebuild it by issuing the following command:

NODE_VERSION=10.13.0 YARN_VERSION=1.10.1 ANDROID_SDK_VERSION=4333796 ANDROID_PLATFORM=27 BUILD_TOOLS_VERSION=28.0.3 make build

Optionally you can add the following variables:

• REVISION=int, which will add -0, -1, -2... suffix to the build image. If not specified it is set to 0.
• IMAGE=name, which will override default image name. If not specified it is set to swmansion/react-native-android.

Versioning

The built image will have a docker tag of with version of the following syntax:

NODE_VERSION-YARN_VERSION-ANDROID_SDK_VERSION-ANDROID_PLATFORM-BUILD_TOOLS_VERSION-REVISION

It may look inconvenient to use but it allows you to refer to particular combination of versions if you're using CI.

Sample usage

Typically if you want to invoke a build of a React Native app using that image you should call the following commands from your application's directory:

Enter the image, while mounting application as /app:

docker run --rm -ti -v `pwd`:/app swmansion/react-native-android:10.13.0-1.10.1-4333796-27-28.0.3-0 bash

Inside the container, change the directory to the application's directory:

cd /app

Install dependencies:

yarn install

Invoke the actual build (debug build in such case):

cd android && ./gradlew assembleDebug

The .apk file will be located at /app/android/app/build/outputs/apk/debug/app-debug.apk
