awsenv - AWS环境配置加载程序

awsenv

AWS environment config loader.

awsenv is a small binary that loads AWS environment variables for an AWS profile from ~/.aws/credentials - useful if you're regularly switching credentials and using tools like Vagrant. In addition to aws_access_key_id and aws_secret_access_key, it will also optionally load settings for aws_keyname and aws_keypath.

Installation

# install Go from https://golang.org/dl/export GOPATH=$HOME/gogo get -u github.com/soniah/awsenv

This will automatically download, compile and install the awsenv executable to $GOPATH/bin.

Usage

Import variables into your environment by eval-ing a backticked call to awsenv.

eval `awsenv profile-name`

For example, if you had the following credential files:

% cat ~/.aws/credentials[example1]aws_access_key_id = DEADBEEFDEADBEEFaws_secret_access_key = DEADBEEFDEADBEEF1vzfgefDEADBEEFDEADBEEF% cat /var/tmp/credentials[example2]aws_access_key_id = DEADBEEFDEADBEEFaws_secret_access_key = DEADBEEFDEADBEEF1vzfgefDEADBEEFDEADBEEFaws_keyname = 'example2_key'aws_keypath = "~/.ssh/example2.pem"

The following shell commands would import AWS variables into your environment:

% eval `awsenv example1`% env | grep AWSAWS_ACCESS_KEY_ID=DEADBEEFDEADBEEFAWS_SECRET_ACCESS_KEY=DEADBEEFDEADBEEF1vzfgefDEADBEEFDEADBEEF% eval `awsenv example2 -f /var/tmp/credentials -v`AWS_ACCESS_KEY_ID=DEADBEEFDEADBEEFAWS_SECRET_ACCESS_KEY=DEADBEEFDEADBEEF1vzfgefDEADBEEFDEADBEEFAWS_KEYNAME=example2_keyAWS_KEYPATH=/Users/sonia/.ssh/example2.pem

Vagrant Example

In a Vagrantfile you could do:

override.ssh.username = "ubuntu"aws.keypair_name = ENV['AWS_KEYNAME']override.ssh.private_key_path = ENV['AWS_KEYPATH']
