Its not currently possible to run the aws_instance resource and data source acceptance testing outside us-west-2 and get meaningful results. For example, setting AWS_DEFAULT_REGION=us-east-1 while running the tests today returns: Tests failed: 61 (59 new), passed: 6

Many of the failures are similar to:

--- FAIL: TestAccAWSInstance_basic (8.76s)
    testing.go:518: Step 0 error: Check failed: InvalidZone.NotFound: The zone 'us-west-2a' does not exist.

And:

--- FAIL: TestAccAWSInstance_disableApiTermination (17.22s)
    testing.go:518: Step 0 error: Error applying: 1 error(s) occurred:
        
        * aws_instance.foo: 1 error(s) occurred:
        
        * aws_instance.foo: Error launching source instance: InvalidAMIID.NotFound: The image id '[ami-4fccb37f]' does not exist

We can switch to using the aws_region, aws_availability_zones, and aws_partition data sources as appropriate to remove hardcoded us-west-2 pieces. For acceptance tests that cannot occur outside of us-west-2 (due to very specific AMIs, etc.), we can set them up with t.Skip().

resource/aws_instance: Always refresh associate_public_ip_address and…
2a23d08 
… ipv6_address_count into Terraform state

In the Terraform 0.12 Provider SDK acceptance testing framework, attributes that do not call `ResourceData.Set()` are no longer automatically ignored during `ImportStateVerify` testing. Here we opt to always refresh the `associate_public_ip_address` and `ipv6_address_count` attributes into the Terraform state. This change is backwards compatible.

This changeset is the bare minimum to ensure the existing acceptance testing is in a better passing state with the Terraform 0.12 Provider SDK, however there are likely many more additional changes required once the `ImportStateVerify` test step is applied to all acceptance tests for the resource as part of some upcoming technical debt work (#4987).

Previous output from Terraform 0.12 Provider SDK acceptance testing:

```

Look also at acceptance tests for:

  • aws_ami_from_instance
  • aws_autoscaling_attachment
  • aws_autoscaling_lifecycle_hook
  • aws_autoscaling_notification
  • aws_autoscaling_schedule
  • aws_eip_association
  • aws_elb_attachment
  • aws_launch_configuration
  • aws_launch_template
  • aws_lb_target_group_attachment
  • aws_network_interface_attachment
  • aws_network_interface
  • aws_route_table
  • aws_route
  • aws_spot_fleet_request
  • aws_spot_instance_request
  • aws_volume_attachment

as there are some with hard-coded AMIs (look for ami or image_id attributes).

Not all instance types are available in all regions/partitions so there will need to be cleanup of instance_type also.

We can use the new EC2 DescribeInstanceTypeOfferings API to add a PreCheck that the test's instance type is supported.

Unfortunately instance type regional availability varies in other AWS services beyond EC2 as well. The CloudFormation Linter gathers instance type regional availability for over a dozen services from the pricing API here
