Get AWS credentials in various ways.

1. Add the dependency to your shard.yml:

dependencies:
  aws-credentials:
    github: y2k2mt/aws-credentials.cr

2. Run shards install

Providers resolves credentials in order from given Provider.

In the example below, at first ,Providers resolves credentials from EnvProvider ('AWS_ACCESS_KEY_ID' and 'AWS_SECRET_ACCESS_KEY' in env) and then resolves credentials from SharedCredentialFileProvider ('~/.aws/credentials').

require "aws-credentials"

include Aws::Credentials

provider = Providers.new ([
  EnvProvider.new,
  SharedCredentialFileProvider.new
] of Provider)

credentials = provider.credentials
# Aws::Credentials::Credentials(@access_key_id="AKIA...",@expiration=nil,@secret_access_key="mVlf...",@session_token=nil)

Current Provider implementation is as follows:

• EnvProvider
• SharedCredentialFileProvider
• InstanceMetadataProvider
• ContainerCredentialProvider
• AssumeRoleProvider
  • Usage: Please watch spec/it/assume_role_with_sts_spec.cr
• SimpleCredentials (Simply holds given credentials)
