User Access Management

Managing user access in DC/OS Open Source deployments

Users can be granted access to DC/OS by another authorized user. A default user is automatically created by the first user who logs in to the DC/OS cluster. Users can be added from the web interface or from the CLI.

Add users from the web interface

  1. Launch the DC/OS web interface and log in with your username (Google, GitHub, and Microsoft) and password.

  2. Click on Organization in the left hand menu. From the Users screen, click the plus sign (+) in the upper right corner, and fill in the new user email address. New users are automatically sent an email notifying them of access to DC/OS.

Note: Any user with access to DC/OS can invite more users. Each DC/OS user is an administrator, there is no explicit concept of privileges with DC/OS.

Add users from the CLI

You can add users to your DC/OS cluster from a terminal by using the dcos_add_user.py script. This script is included by default with your DC/OS installation.

Prerequisites:

  1. SSH to a master node and run this command, where <email> is the user’s email:

    sudo -i dcos-shell /opt/mesosphere/bin/dcos_add_user.py <email>
    
  2. Send the URL of your DC/OS cluster (e.g. http://<public-master-ip>/) to the new user. The user specified by <email> can now login and access the cluster.

Delete users

  1. From the Users screen, select the user name and click Delete.
  2. Click Delete to confirm the action.

Switching users

To switch users, you must log out of the current user and then back in as the new user.
