Struct rusoto_credential::ChainProvider [−][src]
pub struct ChainProvider { /* fields omitted */ }
Expand description
Provides AWS credentials from multiple possible sources using a priority order.
The following sources are checked in order for credentials when calling credentials
:
- Environment variables:
AWS_ACCESS_KEY_ID
andAWS_SECRET_ACCESS_KEY
credential_process
command in the AWS config file, usually located at~/.aws/config
.- AWS credentials file. Usually located at
~/.aws/credentials
. - IAM instance profile. Will only work if running on an EC2 instance with an instance profile/role.
If the sources are exhausted without finding credentials, an error is returned.
The provider has a default timeout of 30 seconds. While it should work well for most setups,
you can change the timeout using the set_timeout
method.
Example
use std::time::Duration;
use rusoto_credential::ChainProvider;
let mut provider = ChainProvider::new();
// you can overwrite the default timeout like this:
provider.set_timeout(Duration::from_secs(60));
Warning
This provider allows the credential_process
option in the AWS config
file (~/.aws/config
), a method of sourcing credentials from an external process. This can
potentially be dangerous, so proceed with caution. Other credential providers should be
preferred if at all possible. If using this option, you should make sure that the config file
is as locked down as possible using security best practices for your operating system.
Implementations
Set the timeout on the provider to the specified duration.
Create a new ChainProvider
using a ProfileProvider
with the default settings.
Create a new ChainProvider
using the provided ProfileProvider
