## To prepare an image suitable as base for Gitlab CI use
## image name must match gitlab repository name, you can play just with the tag
## the part after :
# export CI_IMAGE_NAME="registry.gitlab.com/retroshare/retroshare:android_arm_base"
# docker build --squash --tag "${CI_IMAGE_NAME}" \
# --build-arg QT_INSTALLER_JWT_TOKEN="your qt JWT token goes here"  .
#
# To build Android ARMv8 (64 bit) package pass also
# export CI_IMAGE_NAME="registry.gitlab.com/retroshare/retroshare:android_arm64_base"
# --build-arg ANDROID_NDK_ARCH=arm64 --build-arg ANDROID_PLATFORM_VER=21

## --squash is very important in case of GitlabCI shared runners as they are
## limited to 25GB disk size

## To push it to gitlab CI registry you need first to login and the to push
# docker login registry.gitlab.com
# docker push ${CI_IMAGE_NAME}

## To extract the generated APK easily you can run after the build complete
# docker cp \
#	$(docker create --rm ${CI_IMAGE_NAME}):/retroshare-service-android-build/android-build/build/outputs/apk/debug/android-build-debug.apk \
#	/tmp/RetroShare_Android_Service.apk
