ElasticBeanstalk environment does not get updated

[ghost]

This issue was originally opened by @andys-github as hashicorp/terraform#28356. It was migrated here as a result of the provider split. The original body of the issue is below.

I was trying to adjust the minimum and maximum capacity for an ElasticBeanstalk environment. The terraform plan below shows that it would change the capacity:

But when I tried to verify it from the ElasticBeanstalk Configuration dashboard, I saw:

Please note, I tried updating the platform version of the environment just to be sure if it is only the min & max size that has an issue. But no, even the platform version doesn't get updated.

Also, not sure if it would be of any use, but I am using terraform modules to create/update the environment.

@andys-github Thanks for taking the time to bring this up. Can you provide the configuration you're using? It's possible that the modules are failing to perform the update.

There's at least one Terraform AWS Provider acceptance test (TestAccAWSBeanstalkEnv_settings_update) that verifies updates to Elastic Beanstalk environment takes effect:

Initially:

resource "aws_elastic_beanstalk_environment" "test" {
  application         = aws_elastic_beanstalk_application.test.name
  name                = "yakstalk"
  solution_stack_name = data.aws_elastic_beanstalk_solution_stack.test.name

  setting {
    namespace = "aws:ec2:vpc"
    name      = "VPCId"
    value     = aws_vpc.test.id
  }

  setting {
    namespace = "aws:ec2:vpc"
    name      = "Subnets"
    value     = aws_subnet.test.id
  }

  setting {
    namespace = "aws:ec2:vpc"
    name      = "AssociatePublicIpAddress"
    value     = "true"
  }

  setting {
    namespace = "aws:autoscaling:launchconfiguration"
    name      = "SecurityGroups"
    value     = aws_security_group.test.id
  }

  setting {
    namespace = "aws:autoscaling:launchconfiguration"
    name      = "IamInstanceProfile"
    value     = aws_iam_instance_profile.test.name
  }

  setting {
    namespace = "aws:elasticbeanstalk:environment"
    name      = "ServiceRole"
    value     = aws_iam_role.service_role.name
  }
}

Update:

resource "aws_elastic_beanstalk_environment" "test" {
  application         = aws_elastic_beanstalk_application.test.name
  name                = "yakstalk"

    value     = aws_vpc.test.id
  }

  setting {
    namespace = "aws:ec2:vpc"
    name      = "Subnets"
    value     = aws_subnet.test.id
  }

  setting {
    namespace = "aws:ec2:vpc"
    name      = "AssociatePublicIpAddress"
    value     = "true"
  }

  setting {
    namespace = "aws:autoscaling:launchconfiguration"

  setting {
    namespace = "aws:elasticbeanstalk:environment"
    name      = "ServiceRole"
    value     = aws_iam_role.service_role.name
  }

  setting {
    namespace = "aws:elasticbeanstalk:application:environment"
    name      = "ENV_STATIC"
    value     = "true"
  }

  setting {
    namespace = "aws:elasticbeanstalk:application:environment"
    name      = "ENV_UPDATE"
    value     = "true"
  }

  setting {
    namespace = "aws:elasticbeanstalk:application:environment"
    name      = "ENV_REMOVE"
    value     = "true"
  }

  setting {
    namespace = "aws:autoscaling:scheduledaction"
    resource  = "ScheduledAction01"
    name      = "MinSize"
    value     = 2
  }

  setting {
    namespace = "aws:autoscaling:scheduledaction"
    resource  = "ScheduledAction01"
    name      = "MaxSize"
    value     = 3
  }

  setting {
    namespace = "aws:autoscaling:scheduledaction"
    resource  = "ScheduledAction01"
    name      = "StartTime"
    value     = "2016-07-28T04:07:02Z"
  }
}

@YakDriver thanks for looking into it. Here are the details that might help you:

You might have noticed the backend is "http". It is so because we are using gitlab-terraform for building up our infrastructures. Let me know if you need anything else.

Hi team, please let me know if there's anything else expected from my end.

Here's the log from terraform apply : Releasing state lock. This may take a few moments... Apply complete! Resources: 0 added, 3 changed, 0 destroyed. Saving cache for successful job

Even though it says 3 changed, when I checked via aws console nothing had been updated.

@YakDriver : any updates??
