Changing multiple aws_elastic_beanstalk_configuration_template settings at the same time will result in an incorrectly generated template

[grahamleslie]

If you change multiple Elastic Beanstalk Configuration Template settings with different names in the same apply, Terraform will incorrectly update the template.

Terraform Version

0.10.7

Terraform Configuration Files

Step 1

resource "aws_elastic_beanstalk_configuration_template" "eb_test_configuration_template" {
    name = "eb-test-configuration-template"
    application = "${aws_elastic_beanstalk_application.eb_test.name}"
    solution_stack_name = "${var.solution_stack}"
    setting {
        namespace = "aws:elasticbeanstalk:application:environment"
        name = "TEST"
        value = "0"
    }

Step 2

resource "aws_elastic_beanstalk_configuration_template" "eb_test_configuration_template" {
    name = "eb-test-configuration-template"
    application = "${aws_elastic_beanstalk_application.eb_test.name}"
    solution_stack_name = "${var.solution_stack}"
    setting {
        namespace = "aws:elasticbeanstalk:application:environment"
        name = "TEST"
        value = "2"
    }
    setting {
        namespace = "aws:elasticbeanstalk:application:environment"
        name = "TEST2"
        value = "1"
    }

Generated Template

EnvironmentConfigurationMetadata:
  DateCreated: '1508448368000'
  DateModified: '1508448684000'
Platform:
  PlatformArn: arn:aws:elasticbeanstalk:us-east-1::platform/Docker running on 64bit Amazon Linux/2.7.3
OptionSettings:
  aws:elasticbeanstalk:application:environment:
    TEST2: '1'
EnvironmentTier:
  Type: Standard
  Name: WebServer
AWSConfigurationTemplateVersion: 1.1.0.0

Expected Behavior

• Apply Step 1
• A template should be generated with TEST: 0
• Apply Step 2
• The template should be updated to have both TEST: 2 and TEST2: 1

Actual Behavior

• Apply Step 1
• A template should be generated with TEST: 0
• Apply Step 2
• The template is updated to have only TEST2: 1 and does not reflect the Terraform resource

Steps to Reproduce

• Apply Step 1
• Apply Step 2
• Inspect the generated template in S3
