Configuration

gasy can be configured by passing the required flags (see gasy -h). You can also write some of the parameters in a configuration file: ~/.gasy.toml:

[aws]
clientListLocation = "/Users/dev/aws-accounts.json"
mfaSerial = "arn:aws:iam::123456789012:mfa/user"

[yubikey]
slotName = "Amazon Web Services:user@account"

The clientlist is expected to be a json file using the following format:

{
  "accounts": [
    {
      "id": "123456789012",
      "name": "account1",
      "sid": "91bb981a-12if-475a-a940-fc67abcddf10",
      "description": "Main account"
    },
    {
      "id": "123456789098",
      "name": "account2",
      "sid": null,
      "description": "test account"
    }
  ]
}

Dependencies

Gasy depends on the ykman CLI tool provided by YubiCo. It can be installed on mac with brew: brew install ykman
