2019.2.4f1 for 2019 versions, you will need a
specific Unity license (because that is not the same docker image). Add the content of your specific
Unity license in your CI's environment variable :
UNITY_LICENSE_CONTENT_ANDROID. This is not
required anymore now that images share a base image

By default the apk is not signed and the build will use the Unity's default debug key. For security reasons, you should not add your keystore to git.
Encode your keystore
Encode your keystore file as base64 using openssl:
openssl base64 -A -in yourKeystore.keystore
Copy the result to your CI's environment variable
Add following environment variables:
KEYSTORE_PASS: Keystore pass
KEY_ALIAS_NAME: Keystore alias name to use (if not set, the program will use the alias name set in Project's PlayerSettings)
KEY_ALIAS_PASS: Keystore alias pass to use
Note about keystore security, if you would like to use another solution for storage, see Where to Store Android KeyStore File in CI/CD Cycle?.
Android app bundle

Bundle version code
The bundle version code must be increment for each deployed build.
To simplify the process, the
BUNDLE_VERSION_CODE env var is used and set as bundle version code.
Currently, for gitlab,
BUNDLE_VERSION_CODE = $CI_PIPELINE_IID.
If you use another CI solution, set a CI env var incrementing for each pipeline.

You will also need to add a Gemfile to your project to install the
fastlane gem. Something like
and then copy the file to the current directory prior to installing the gem. eg
cp $CI_PROJECT_DIR/Gemfile ..
That is the simplest way with command line but you can also make
fastlane/Appfile, with the following command after building a temporary gradle project (export
gradle project option in Unity build settings):
Then run the following command:
fastlane supply init
and update all metadata, images, changelogs, etc... These will be uploaded to the store everytime. Refer to fastlane supply documentation for more details.
