Struct CredentialProcessProvider

Source
pub struct CredentialProcessProvider { /* private fields */ }
Available on crate feature credentials-process only.
Expand description

External process credentials provider

This credentials provider runs a configured external process and parses its output to retrieve credentials.

The external process must exit with status 0 and output the following JSON format to stdout to provide credentials:

{
    "Version:" 1,
    "AccessKeyId": "access key id",
    "SecretAccessKey": "secret access key",
    "SessionToken": "session token",
    "Expiration": "time that the expiration will expire"
}

The Version must be set to 1. AccessKeyId and SecretAccessKey are always required. SessionToken must be set if a session token is associated with the AccessKeyId. The Expiration is optional, and must be given in the RFC 3339 date time format (e.g., 2022-05-26T12:34:56.789Z).

If the external process exits with a non-zero status, then the contents of stderr will be output as part of the credentials provider error message.

This credentials provider is included in the profile credentials provider, and can be configured using the credential_process attribute. For example:

[profile example]
credential_process = /path/to/my/process --some --arguments
