SAML

SAML Overview

• SAML (Security Assertion Markup Language) is an open standard source that allows to pass authentication and authorization credentials within SAML providers.

• SAML has two types of providers

  1. Service Provider

  2. Identity Provider

• In Spinnaker, we explore the methods to setup Identity provider. During the authentication process, a cryptographically signed XML will be sent to the API gateway (Gate) with user identity information to confirm authentication and authorization.

Identity Provider Setup

• Download the metadata.xml file from SAML Identity Provider (IdP). Content in the metadata, looks something similar to the content available in the below attached text file SAML-IdP-metadata.txt

• Create a Spinnaker SAML Application.

• Specify the login URL as https://localhost:8084/saml/SSO. Replace “localhost” with Gate’s address, if available.

• Provide a unique entity ID.

• Enable all the users who will be accessing the Spinnaker Instance.

• Execute the below command, to generate a keystore and key in a new Java Keystore with password

      keytool -genkey -v -keystore saml.jks -alias saml -keyalg RSA -keysize 2048 -
      validity 10000

• To re-deploy halyard, execute the following command

  $KEYSTORE_PATH= # /path/to/keystore.jks
  $KEYSTORE_PASSWORD=hunter2
  $METADATA_PATH= # /path/to/metadata.xml
  $SERVICE_ADDR_URL=https://localhost:8084
  $ISSUER_ID=spinnaker.test
  hal config security authn saml edit \
  --keystore $KEYSTORE_PATH
  --keystore-alias saml
  
  --keystore-password $KEYSTORE_PASSWORD
  --metadata $METADATA_PATH
  --issuer-id $ISSUER_ID \
  --service-address-url $SERVICE_ADDR_URL
  hal config security authn saml enable

Note: Append /gate to the ‘service-address-url’ while trying to access quickstart images.

Next Steps

• Now that the SAML setup for Spinnaker authentication is completed, proceed further to setup authorization.
