getenv
will fetch Google Cloud (Compute Engine) metadata attributes and print them as K=V pairs ready to be exported
as environment variables.
Example:
getenv
MY_VARIABLE=SOMEVALUE
Export all metadata attributes as ENV variables for current shell session and store them in /etc/environment for future sessions:
export $(getenv)
getenv 1>> /etc/environment
or
getenv 1>> /etc/environment
source /etc/environment
