红帽全球峰会9.3. 使用命令行管理应用程序凭证
您可以使用命令行来创建和删除应用凭证。
create 子命令基于当前源的帐户创建一个应用程序凭据。例如，当作为 admin 用户提供凭证时创建凭证，会将同一角色授予应用程序凭证：
$ openstack application credential create --description "App Creds - All roles" AppCredsUser
+--------------+----------------------------------------------------------------------------------------+
| Field | Value |
+--------------+----------------------------------------------------------------------------------------+
| description | App Creds - All roles |
| expires_at | None |
| id | fc17651c2c114fd6813f86fdbb430053 |
| name | AppCredsUser |
| project_id | 507663d0cfe244f8bc0694e6ed54d886 |
| roles | member reader admin |
| secret | fVnqa6I_XeRDDkmQnB5lx361W1jHtOtw3ci_mf_tOID-09MrPAzkU7mv-by8ykEhEa1QLPFJLNV4cS2Roo9lOg |
| unrestricted | False |
+--------------+----------------------------------------------------------------------------------------+警告
使用 --unrestricted 参数可让应用程序凭证创建和删除其他应用程序凭证和信任。这可能是危险的行为，默认是禁用的。您不能将 --unrestricted 参数与其他访问规则结合使用。
默认情况下，生成的角色成员资格包括分配给创建凭据的帐户的所有角色。您可以把访问权限委派给特定角色来限制角色成员资格：
$ openstack application credential create --description "App Creds - Member" --role member AppCredsUser
+--------------+----------------------------------------------------------------------------------------+
| Field | Value |
+--------------+----------------------------------------------------------------------------------------+
| description | App Creds - Member |
| expires_at | None |
| id | e21e7f4b578240f79814085a169c9a44 |
| name | AppCredsUser |
| project_id | 507663d0cfe244f8bc0694e6ed54d886 |
| roles | member |
| secret | XCLVUTYIreFhpMqLVB5XXovs_z9JdoZWpdwrkaG1qi5GQcmBMUFG7cN2htzMlFe5T5mdPsnf5JMNbu0Ih-4aCg |
