What's this?

getenv will fetch GCE metadata attributes and print them as K=V pairs ready to be exported as environment variables.

Example:

./getenv
MY_VARIABLE=SOMEVALUE

How to use

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
