TLS Certificate Auth Backend HTTP API

This is the API documentation for the Vault TLS Certificate authentication backend. For general information about the usage and operation of the TLS Certificate backend, please see the Vault TLS Certificate backend documentation.

This documentation assumes the TLS Certificate backend is mounted at the /auth/cert path in Vault. Since it is possible to mount auth backends at any location, please update your API calls accordingly.

Create CA Certificate Role

Sets a CA cert and associated parameters in a role name.

Method	Path	Produces
POST	/auth/cert/certs/:name	204 (empty body)

Parameters

• name (string: <required>) - The name of the certificate role.
• certificate (string: <required>) - The PEM-format CA certificate.
• allowed_names (string: "") - Constrain the Common and Alternative Names in the client certificate with a [globbed pattern] (https://github.com/ryanuber/go-glob/blob/master/README.md#example). Value is a comma-separated list of patterns. Authentication requires at least one Name matching at least one pattern. If not set, defaults to allowing all names.
• policies (string: "") - A comma-separated list of policies to set on tokens issued when authenticating against this CA certificate.
• display_name (string: "") - The display_name to set on tokens issued when authenticating against this CA certificate. If not set, defaults to the name of the role.
• ttl (string: "") - The TTL period of the token, provided as a number of seconds. If not provided, the token is valid for the the mount or system default TTL time, in that order.
