Get ready to use AWS Config from arguments and environment variables.

Do you want to:

• Have most of you AWS Config loaded from environment variables?
• Handle JSON shared credentials and config files?
• Get AWS Config from arguments?

Setup

1. Run npm install -g extra-awsconfig in console.
2. To install this as a package use npm install extra-awsconfig.

Console

awsconfig
# get default AWS config

awsconfig --access_key_id "..." --secret_access_key "..."
awsconfig --accessKeyId "..." --secretAccessKey "..."
awsconfig --id "..." --key "..."
# get AWS config with custom credentials
## all commands are equivalent

awsconfig --region "us-west-1"
# get AWS config with region="us-west-1"

awsconfig --sslEnabled=0
# get AWS config with SSL disabled
## enable SSL with simply --sslEnabled

awsconfig --profile dev
# get AWS config with "dev" profile
## credential and config associated with the profile is loaded

awsconfig --credentialsFile credentials.json
# use a custom credentials file
## credentials/config file can be INI for JSON
