SAML security considerations¶
From the MKE web UI you can download a client bundle with which you can access MKE using the CLI and the API.
A client bundle is a group of certificates that enable command-line access and API access to the software. It lets you authorize a remote Docker engine to access specific user accounts that are managed in MKE, absorbing all associated RBAC controls in the process. Once you obtain the client bundle, you can execute Docker Swarm commands from your remote machine to take effect on the remote cluster.
Previously-authorized client bundle users can still access MKE, regardless of the newly configured SAML access controls.
Mirantis recomments that you take the following steps to ensure that access from the client bundle is in sync with the identity provider, and to thus prevent any previously-authorized users from accessing MKE through their existing client bundle:
Remove the user account from MKE that grants the client bundle access.
If group membership in the identity provider changes, replicate the change in MKE.
Continue using LDAP to sync group membership.
To download the client bundle:
Log in to the MKE web UI.
In the navigation menu at the left, click the user name drop-down to display the available options.
Click your account name to display the available options.
Click My Profile.
Click the New Client Bundle drop-down in the details pane and select Generate Client Bundle.
(Optional) Enter a name for the bundle into the Label field.
Click Confirm to initiate the bundle download.
