Optional configuration

You can optionally configure Otomi to use an external IDP (Azure AD) and use an external Key Management Service (KMS) provider for SOPS. Below you can find detailed instructions on how to set up Azure AD as an external IDP and configure KMS. We will soon add more instructions for other IDPs, such as Amazon Incognito, Google Identity, and Okta.

Use Azure AD as IDP#

The authentication of brokered identities through Azure AD requires a service principal with certain Azure AD API permissions. An app registration needs to be created with the following API permissions:

API / Permission nameTypeDescription
Microsoft Graph / emailDelegatedView users' email address
Microsoft Graph / openidDelegatedSign users in
Microsoft Graph / profileDelegatedView users' basic profile
Microsoft Graph / User.ReadDelegatedSign in and read user profile

And the following token configurations:

ClaimDescriptionToken typeOptional settings
family_nameProvides the last name, surename, or family nameID-
given_nameProvides the first or "give" name of the userID-
groupsOptional formatting for group claimsID, Access, SAMLDefault
upnAn identifier for the user that can be used ...IDDefault

Note that the group type should be set to 'security groups'.

At the 'Authentication' tab you should be able to set the following callback URL§s and enable that both "Access tokens" and "ID tokens" are issued and public client flows are allowed:

  • https://keycloak.<dns-zone-name>/realms/master/broker/otomi-idp/endpoint
  • https://keycloak.<dns-zone-name>
note

otomi-idp is the default KeyCloak alias (shown as login title). To use another alias, add the following to the chart values:

keycloak:
idp:
alias: <your-alias>

Use KMS to manage keys for encryption#

If you would like the secrets in the values repository to be encrypted, you will have to setup an account with your Key Management Service (KMS) provider. It is needed by sops, the tool used for encryption.

Find quickstart documentation below on how to setup KMS access per supported provider:

Follow the instructions of the provider of your choosing and jot down the credentials obtained for the next steps.
