This Docker build installs the spring-security-saml application in a tomcat image. Once the configuration files are updated with the Okta organization and API token, various scripts can be executed to create the SAML app within Okta and the spring-security-saml module configured as a Service Provider.

• Docker is installed and ready to go. If not, Visit https://www.docker.com/

• Make a copy of the example.conf file. Like this: cp example.conf yourorg.conf
• Update yourorg.conf with appropriate OKTAORG and API_TOKEN variables
• IMPORTANT: Ensure docker-machine ip default returns a valid and correct IP Address.
• Run ./create-saml-app-in-okta.sh yourorg.conf to create a SAML application in your Okta org -- Note the value of the 'id' field returned. Verify other values as well. -- If you have jq, try ./create-saml-app.sh | jq '.id' -- This id value is your application_id -- Run ./get-metadata.sh <application_id> > idp.xml. This will create the idp.xml file that will be used to configure spring-security-saml module.
• Log in to your Okta org as an Administrator
• Verify the settings for this newly created application and assign it to a user
• Run docker build -t spring-security-saml .
• Run docker run --rm -p 8080:8080 spring-security-saml
• Log in as this user and Test IdP initiated SSO flow first (this is important as spring-security-sample sets metadata based on this)
• Feel free to test the SP init flow by accessing the sample
