docker-android-fastlane

You can use this image on such CI/CD like Bitbucket/GitLab/etc, which uses docker containers.

Example for bitbucket-pipelines.yml file:

image: softartdev/android-fastlane

pipelines:
  default:
    - step:
        name: Build step
        script:
          - ./gradlew build
    - step:
        name: Test step
        script:
         - ./gradlew test
    - step:
        name: Publish step
        script:
         - fastlane playstore

For fastlane step within your repository you must have Fastfile with match lane inside:

default_platform(:android)

platform :android do
  lane :playstore do
    gradle(
      task: 'bundle', # for AAB, or use 'assemble' for APK
      build_type: 'Release'
    )
    upload_to_play_store # Uploads the APK/AAB built in the gradle step above
  end
end

Desirable debug it locally before push to remote repository.
