Error
An error occurred: sampleEnvironment - Environment failed to launch as it entered Terminated state.

Note
The profile beanstalk-test-deployment has already the IAM roles:

• AWSElasticBeanstalkFullAccess
• AdministratorAccess

回答1:

You need to create the aws-elasticbeanstalk-ec2-role AWS::IAM::InstanceProfile and provide it in the sampleConfigurationTemplate's OptionSettings:

- Namespace: aws:autoscaling:launchconfiguration
  OptionName: IamInstanceProfile
  Value: aws-elasticbeanstalk-ec2-role

The role can use these Managed Policy Arns:

- arn:aws:iam::aws:policy/AWSElasticBeanstalkWebTier
- arn:aws:iam::aws:policy/AWSElasticBeanstalkWorkerTier
- arn:aws:iam::aws:policy/AWSElasticBeanstalkMulticontainerDocker

If adding this role doesn't help, the error could also indicate a failing .ebextensions. I once got this error by calling a nonexistent KeyName in ebextensions.
