requestAuthentication详解_f5_02

什么是RequestAuthentication

RequestAuthentication defines what request authentication methods are supported by a workload. It will reject a request if the request contains invalid authentication information, based on the configured authentication rules. A request that does not contain any authentication credentials will be accepted but will not have any authenticated identity.

就是用来配置jwt的

资源详解

Field

Type

Description

Required

​​selector​​

​​WorkloadSelector​​

The selector determines the workloads to apply the RequestAuthentication on. If not set, the policy will be applied to all workloads in the same namespace as the policy.

No

​​jwtRules​​

​​JWTRule[]​​

Define the list of JWTs that can be validated at the selected workloads’ proxy. A valid token will be used to extract the authenticated identity. Each rule will be activated only when a token is presented at the location recorgnized by the rule. The token will be validated based on the JWT rule config. If validation fails, the request will be rejected. Note: if more than one token is presented (at different locations), the output principal is nondeterministic.

No

Field

Type

Description

Required

​​issuer​​

​​string​​

Identifies the issuer that issued the JWT. See ​​issuer​​​ A JWT with different ​​iss​​​ claim will be rejected.Example: ​​Auth0: Secure access for everyone. But not just anyone.​​ Example: ​​[email protected]​​

​​audiences​​

​​string[]​​

The list of JWT ​​audiences​​​. that are allowed to access. A JWT containing any of these audiences will be accepted.The service name will be accepted if audiences is empty.Example:​​audiences: - bookstore_android.apps.example.com bookstore_web.apps.example.com​​

No

​​jwksUri​​

​​string​​

URL of the provider’s public key set to validate signature of the JWT. See ​​OpenID Discovery​​​.Optional if the key set document can either (a) be retrieved from ​​OpenID Discovery​​​ of the issuer or (b) inferred from the email domain of the issuer (e.g. a Google service account).Example: ​​https://www.googleapis.com/oauth2/v1/certs​​Note: Only one of jwksuri and jwks should be used. jwksuri will be ignored if it does.

No

​​jwks​​

​​string​​

JSON Web Key Set of public keys to validate signature of the JWT. See ​​https://auth0.com/docs/jwks.Note​​: Only one of jwksuri and jwks should be used. jwksuri will be ignored if it does.

No

​​fromHeaders​​

​​JWTHeader[]​​

List of header locations from which JWT is expected. For example, below is the location spec if JWT is expected to be found in ​​x-jwt-assertion​​​ header, and have “Bearer ” prefix:​​fromHeaders: - name: x-jwt-assertion prefix: "Bearer "​​

No

​​fromParams​​

​​string[]​​

List of query parameters from which JWT is expected. For example, if JWT is provided via query parameter ​​my_token​​​ (e.g /path?my_token=), the config is:​​fromParams: - "my_token"​​

No

​​outputPayloadToHeader​​

​​string​​

This field specifies the header name to output a successfully verified JWT payload to the backend. The forwarded data is ​​base64_encoded(jwt_payload_in_JSON)​​. If it is not specified, the payload will not be emitted.

No
