Q:

AWS Elastic Beanstalk ServiceRole Error When Logging In To A Role

I'm logging into a role through SSO and I'm trying to create a new Elastic Beanstalk environment (newest tomcat if it matters) and I am getting the following error which is preventing me from even getting the environment started building:

(Namespace: 'aws:elasticbeanstalk:environment', OptionName: 'ServiceRole'): Invalid service role

This is happening even when I am trying to clone an existing environment.  I've tried to auto generate a service role and to manually create one.  Both are giving the error.  This error does not happen when I am logging into a user with the same permissions.

A:

When you clone an environment using the Elastic Beanstalk console, you have the option to choose a new platform and a service role. Service role is a new concept in beanstalk documented here. Service is not required if you are using basic health monitoring but it is required if you choose to use enhanced health monitoring.
When creating an environment you can choose to pass an IamInstanceProfile (typically named aws-elasticbeanstalk-ec2-role) and a service role (typically named aws-elasticbeanstalk-service-role). These two roles are required when using Enhanced Application Health Monitoring.
Please note that these two roles require a completely a different set of permissions and you should use different roles for each of them. You can find the list of permissions required for Service Role and Instance profile documented here.
When creating/cloning/modifying environments using AWS console you will be shown an option to choose a service role. If you have never used a Service role before, you will be presented with an option to "Create a new role". The console allows you to create the Service role required by beanstalk using a single button click. You can view the permissions before creating the role.
After the first create, the console will present you with a dropdown with the role you created previously (typically named aws-elasticbeanstalk-service-role) and you can reuse this service role.
From the documentation: "A service role is the IAM role that Elastic Beanstalk assumes when calling other services on your behalf. Elastic Beanstalk uses the service role that you specify when creating an Elastic Beanstalk environment when it calls Amazon Elastic Compute Cloud (Amazon EC2), Elastic Load Balancing, and Auto Scaling APIs to gather information about the health of its AWS resources."
When creating/using a role you need to make sure the IAM user has pass role permission for the role you created. In case you are not using the root account make sure you have the correct policies for the IAM user.
Note the iam:PassRole permission allows your IAM user to pass the role to beanstalk service.
Update
There was an issue with Single Sign On that has now been resolved. Please update here or in the AWS forum thread below if you are still seeing issues.
