#
# This docker file can be used in kubernetes. 
# It accepts all cluster related parameters at run time. 
# It means it's very easy to add new containers to the cluster 
#
# Usage:
#
# * AntMediaServer: Specify the name of the Ant Media Server zip file to install that specify Ant Media Server version to the docker image
# --build-arg AntMediaServer='ant-media-server.zip'
#
# * LicenseKey: Set your license key to this variable to install the latest Ant Media Server automatically to the docker image without needing a zip file. If you use this LicenseKey variable, don't specify AntMediaServer variable (# --build-arg AntMediaServer='ant-media-server.zip')
# --build-arg LicenseKey='your-license-key'
#
# * InstallMediaPush: Set this variable to 'true' to enable headless Chrome on the server for recording and streaming web pages back to Ant Media Server.
# --build-arg InstallMediaPush='true'
#
# * MediaPushVersion: Specify the latest version or latest snapshot version of the Media Push Plugin. It's empty by default and the latest version of the Media Push Plugin will be installed by default.
# If you want to install the latest snapshot version of the Media Push Plugin, you can specify --snapshot
#   
# --build-arg MediaPushVersion='--snapshot'
#
# * Supervisor Configuration (Optional): If you want to use Supervisor to manage the Ant Media Server process, you can enable as follows. With this configuration, you can easily restart, stop the service, or run the `enable_ssl.sh` script for Ant Media Server. 
# --build-arg UseSupervisor='true'
