### Parameters
|
|
|
|
|
|
|
|
- `Description` `(string: "")` - Human-readable, operator set description that
|
|
|
|
can provide additional context about the binding role. This is an operational
|
|
|
|
field.
|
|
|
|
|
|
|
|
- `AuthMethod` `(string: <required>)` - Name of the auth method for which this
|
|
|
|
rule applies to. This is a required field and the method must exist within state
|
|
|
|
before the cluster administrator can create the rule.
|
|
|
|
|
|
|
|
- `Selector` `(string: "")` - A boolean expression that matches against verified
|
|
|
|
identity attributes returned from the auth method during login. This is
|
2023-02-17 14:38:55 +00:00
|
|
|
optional and when not set, provides a catch-all rule. If set, it must be a
|
|
|
|
valid [go-bexpr][] expression; for example, a dash in the claim name will
|
|
|
|
require it to be encased in quotes and escaped such as
|
|
|
|
`"\"project-developer\" in list.roles"`.
|
|
|
|
|
2022-12-20 10:22:51 +00:00
|
|
|
|
|
|
|
- `BindType` `(string: <required>)` - Adjusts how this binding rule is applied
|
2023-01-26 08:57:44 +00:00
|
|
|
at login time. Valid values are `role`, `policy`, and `management`.
|
2022-12-20 10:22:51 +00:00
|
|
|
|
|
|
|
- `BindName` `(string: <required>)` - Target of the binding. Can be lightly
|
2023-01-26 08:57:44 +00:00
|
|
|
templated using HIL ${foo} syntax from available field names. If the bind
|
|
|
|
type is set to `management`, this should not be set. How it is used depends
|
|
|
|
on the BindType.
