senv

senv = "secure env", it loads enviornment variables from your keychain (for now it supports Mac only)

Adding enviornment variables to keychain using account test_a .

$> senv add test_a a=AAA b=BBB

Show enviornment variables binding to that account

$> senv show test_a
[account]: test_a
====================
a=********
b=********

Show enviorment variables without mask.

$> senv show test_a  --unmask
[account]: test_a
====================
a=AAA
b=BBB

With this you can add your aws key to keychain.

$> senv show my_aws
[account]: my_aws
====================
AWS_ACCESS_KEY_ID=AS****************IA
AWS_SECRET_ACCESS_KEY=A2************************************NL
AWS_SECURITY_TOKEN=AQ********************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************************AF

So I can simly do

$> senv run my_aws aws s3 ls s3://my-bucket/
                           PRE my_folder/
                           PRE my_folder2/
                           ....

If you have multiple awskey like me, you'd better leverage alias.

# Leave this in your .bash_profile
alias k1='senv run aws_k1'
alias k2='senv run aws_k2'
alias k3='senv run aws_k3'

And you can simply do:

$> k1 aws s3 ls s3://k1-bucket/...
$> k2 aws s3 ls s3://k2-bucket/...
$> k3 aws s3 ls s3://k3-bucket/...

Installations

I haven't implemented a pip package, yet. As senv use the standard lib ships with python 2.x, so doesn't really need to pip install it.

You can just download the senv.py to your path.

wget https://raw.githubusercontent.com/tly1980/senv/master/src/senv.py -O /usr/local/bin/senv

chmod a+x /usr/local/bin/senv
