Request: Add environment variable reference/list

[carstenhag]

Hello there! I really like the image Readme's like https://github.com/actions/virtual-environments/blob/main/images/macos/macos-10.15-Readme.md. But when I need to add/write scripts for the CI runner, I am always confused as on what environment variables are available and how they are called.

Is it $ANDROID_HOME, $ANDROID_SDK_HOME, $ANDROID_SDK_ROOT or what is it? I pretty much have to find out doing trial and error.

Hi @carstenhag!
Thanks for your proposal! We'll investigate how many custom env variables (like $ANDROID_HOME, $ANDROID_SDK_HOME, etc) we have and think about the best way of adding them to the docs. Probably they can be added to the related tool section as we currently do for Java

Sounds good!

Found the following environment variables that are mentioned in documentation:

All platforms:
ANDROID_HOME
ANDROID_SDK_ROOT
ANDROID_NDK_HOME
CHROMEWEBDRIVER
EDGEWEBDRIVER
GECKOWEBDRIVER
VCPKG_INSTALLATION_ROOT
CONDA
ANT_HOME
GRADLE_HOME
M2_HOME

Ubuntu:
GOROOT
GOROOT_1_13_X64
GOROOT_1_14_X64
GOROOT_1_15_X64

ANDROID_* and GOROOT definitely should be in documentation. Other variables are optional since those tools are already in PATH and variables are not needed to use. Moved this work item to backlog

Thanks for integrating this :) We can close it now imo, or is there still something to do?

@carstenhag yes, I'm going to close the issue. Thanks for your proposal!
