Identity and Access Management API

Enterprise DC/OS Updated: June 22, 2017

The Identity and Access Management API allows you to manage users, user groups, permissions, and LDAP configuration settings through a RESTful interface. It offers more functionality as the DC/OS GUI.

Request and response format

The API supports JSON only. You must include application/json as your Content-Type in the HTTP header, as shown below.

Content-Type: application/json

Host name and base path

The host name to use will vary depending on where your app is running.

  • If your app runs outside of the DC/OS cluster, you should use the cluster URL. This can be obtained by launching the DC/OS GUI and copying the domain name from the browser. Alternatively, you can log into the DC/OS CLI and type dcos config show core.dcos_url to get the cluster URL. In a production environment, this should be the path to the load balancer which sits in front of your masters.

  • If your app runs inside of the cluster, use master.mesos.

Append /acs/api/v1 to the host name, as shown below.


Authentication and authorization

All IAM endpoints require an authentication token and the dcos:superuser permission—except the auth endpoints. The auth endpoints do not require authentication tokens because their purpose is to return authentication tokens upon successful login.

Obtaining an authentication token

Via the IAM API

To get an authentication token, pass a user name and password in the body of a request to /auth/login. It returns an authentication token as shown below.

  "token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1aWQiOiJib290c3RyYXB1c2VyIiwiZXhwIjoxNDgyNjE1NDU2fQ.j3_31keWvK15shfh_BII7w_10MgAj4ay700Rub5cfNHyIBrWOXbedxdKYZN6ILW9vLt3t5uCAExOOFWJkYcsI0sVFcM1HSV6oIBvJ6UHAmS9XPqfZoGh0PIqXjE0kg0h0V5jjaeX15hk-LQkp7HXSJ-V7d2dXdF6HZy3GgwFmg0Ayhbz3tf9OWMsXgvy_ikqZEKbmPpYO41VaBXCwWPmnP0PryTtwaNHvCJo90ra85vV85C02NEdRHB7sqe4lKH_rnpz980UCmXdJrpO4eTEV7FsWGlFBuF5GAy7_kbAfi_1vY6b3ufSuwiuOKKunMpas9_NfDe7UysfPVHlAxJJgg"

Via the DC/OS CLI

When you log into the DC/OS CLI using dcos auth login, it stores the authentication token value locally. You can reference this value as a variable in curl commands (discussed in the next section).

Alternatively, you can use the following command to get the authentication token value.

dcos config show core.dcos_acs_token

Passing an authentication token

Via the HTTP header

Copy the token value and pass it in the Authorization field of the HTTP header, as shown below.

Authorization: token=eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1aWQiOiJib290c3RyYXB1c2VyIiwiZXhwIjoxNDgyNjE1NDU2fQ.j3_31keWvK15shfh_BII7w_10MgAj4ay700Rub5cfNHyIBrWOXbedxdKYZN6ILW9vLt3t5uCAExOOFWJkYcsI0sVFcM1HSV6oIBvJ6UHAmS9XPqfZoGh0PIqXjE0kg0h0V5jjaeX15hk-LQkp7HXSJ-V7d2dXdF6HZy3GgwFmg0Ayhbz3tf9OWMsXgvy_ikqZEKbmPpYO41VaBXCwWPmnP0PryTtwaNHvCJo90ra85vV85C02NEdRHB7sqe4lKH_rnpz980UCmXdJrpO4eTEV7FsWGlFBuF5GAy7_kbAfi_1vY6b3ufSuwiuOKKunMpas9_NfDe7UysfPVHlAxJJgg

Via curl as a string value

Using curl, for example, you would pass this value as follows.

curl -H "Authorization: token=eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1aWQiOiJib290c3RyYXB1c2VyIiwiZXhwIjoxNDgyNjE1NDU2fQ.j3_31keWvK15shfh_BII7w_10MgAj4ay700Rub5cfNHyIBrWOXbedxdKYZN6ILW9vLt3t5uCAExOOFWJkYcsI0sVFcM1HSV6oIBvJ6UHAmS9XPqfZoGh0PIqXjE0kg0h0V5jjaeX15hk-LQkp7HXSJ-V7d2dXdF6HZy3GgwFmg0Ayhbz3tf9OWMsXgvy_ikqZEKbmPpYO41VaBXCwWPmnP0PryTtwaNHvCJo90ra85vV85C02NEdRHB7sqe4lKH_rnpz980UCmXdJrpO4eTEV7FsWGlFBuF5GAy7_kbAfi_1vY6b3ufSuwiuOKKunMpas9_NfDe7UysfPVHlAxJJgg"

Via curl as a DC/OS CLI variable

You can then reference this value in your curl commands, as shown below.

curl -H "Authorization: token=$(dcos config show core.dcos_acs_token)"

Refreshing the authentication token

Authentication tokens expire after five days by default. If your program needs to run longer than five days, you will need a service account. Please see Provisioning custom services for more information.

While the API returns informative error messages, you may also find it useful to check the logs of the service. Refer to Service and Task Logging for instructions.
