Red Hat Summit3.7. OAuth server metadata
Applications running in OpenShift Container Platform might have to discover information about the built-in OAuth server. For example, they might have to discover what the address of the <namespace_route> is without manual configuration. To aid in this, OpenShift Container Platform implements the IETF OAuth 2.0 Authorization Server Metadata draft specification.
Thus, any application running inside the cluster can issue a GET request to https://openshift.default.svc/.well-known/oauth-authorization-server to fetch the following information:
{
"issuer": "https://<namespace_route>",
"authorization_endpoint": "https://<namespace_route>/oauth/authorize",
"token_endpoint": "https://<namespace_route>/oauth/token",
"scopes_supported": [
"user:full",
"user:info",
"user:check-access",
"user:list-scoped-projects",
"user:list-projects"
],
"response_types_supported": [
"code",
"token"
],
"grant_types_supported": [
"authorization_code",
"implicit"
],
"code_challenge_methods_supported": [
"plain",
"S256"
]
}- 1
- The authorization server’s issuer identifier, which is a URL that uses the
httpsscheme and has no query or fragment components. This is the location where.well-knownRFC 5785 resources containing information about the authorization server are published. - 2
- URL of the authorization server’s authorization endpoint. See RFC 6749.
- 3
- URL of the authorization server’s token endpoint. See RFC 6749.
- 4
- JSON array containing a list of the OAuth 2.0 RFC 6749 scope values that this authorization server supports. Note that not all supported scope values are advertised.
- 5
- JSON array containing a list of the OAuth 2.0
response_typevalues that this authorization server supports. The array values used are the same as those used with theresponse_typesparameter defined by "OAuth 2.0 Dynamic Client Registration Protocol" in RFC 7591. - 6
- JSON array containing a list of the OAuth 2.0 grant type values that this authorization server supports. The array values used are the same as those used with the
grant_typesparameter defined byOAuth 2.0 Dynamic Client Registration Protocolin RFC 7591. - 7
- JSON array containing a list of PKCE RFC 7636 code challenge methods supported by this authorization server. Code challenge method values are used in the
code_challenge_methodparameter defined in Section 4.3 of RFC 7636. The valid code challenge method values are those registered in the IANAPKCE Code Challenge Methodsregistry. See IANA OAuth Parameters.
