AWS auth backend takes in a AWS EC2 instance identity document, its PKCS#7 signature
|
||
|
|
and a client created nonce to authenticates the instance with Vault.
|
||
|
|
|
||
|
|
Authentication is backed by a preconfigured association of AMIs to Vault's policies
|
||
|
|
through 'image/<name>' endpoint. For instances that share an AMI, an instance tag can
|
||
|
|
be created through 'image/<name>/tag'. This tag should be attached to the EC2 instance
|
||
|
|
before the instance attempts to login to Vault.
