* auth/aws: Allow binding by EC2 instance IDs
This allows specifying a list of EC2 instance IDs that are allowed to
bind to the role. To keep style formatting with the other bindings, this
is still called bound_ec2_instance_id rather than bound_ec2_instance_ids
as I intend to convert the other bindings to accept lists as well (where
it makes sense) and keeping them with singular names would be the
easiest for backwards compatibility.
Partially fixes#3797
If you try to use role authorization to get an STS token, you'll get this error:
* Error generating STS keys: AccessDenied: Cannot call GetFederationToken with session credentials
* Accept temp creds in AWS secret backend acceptance tests
The AWS secret backend acceptance tests implicitly accepted long-lived
AWS credentials (i.e., AWS IAM user and/or root credentials) in two
ways:
1. It expected credentials to be passed in via the AWS_ACCESS_KEY_ID and
AWS_SECRET_ACCESS_KEY environment variables. By not accepting
AWS_SESSION_TOKEN or AWS_SECURITY_TOKEN, temporary credentials could
not be passed in. (This also forced all credentials to be passed in
via environment variables, which is a bit ugly).
2. The AWS sts:GetFederationToken call is only allowed from long-term
credentials. This is called by the Vault code which the acceptance
tests exercise.
1 is solved by deleting explicit references to credentials, which allows
the SDK to do one of the things it does best -- find credentials via the
default chain.
2 is a little more complicated. Rather than pass in whatever creds the
acceptance test was run under to the backend, the acceptance test now
creates a new IAM user and gets an access key from it, then passes the
IAM user's creds back to the backend so that it can call
sts:GetFederationToken (and then tries to clean up afterwards).
* Fix Travis build failure
The Travis build was failing because the user creation was happening
regardless of whether it was running in acceptance test mode or not.
This moves the user creation into the acceptance test precheck, which
requires lazily evaluating the credentials when configuring the backend
in the STS accetpance test, and so moving that to a PreFlight closure.
* Reduce blind sleeps in AWS secret backend acceptance tests
This removes a blind "sleep 10 seconds and then attempt to reuse the
credential" codepath and instead just keeps attemtping to reuse the
credential for 10 seconds and fails if there aren't any successful uses
after 10 seconds. This adds a few seconds speedup of acceptance test
runs from my experiments.
In the authentication section of the getting started doc, the token used
to login doesn't match with the one displayed as the command result.
This commit makes sure that both tokens correspond to avoid distracting
newcomers.
