Adds support for `name_prefix` to the `aws_autoscaling_group` and `aws_elb` resources. Unfortunately when using `name_prefix` with `aws_elb`, this means that the specified prefix can only be a maximum of 6 characters in length. This is because the maximum length for an ELB name is 32 characters, and `resource.PrefixedUniqueId` generates a 26-character unique identifier. I was considering truncating the unique identifier to allow for a longer `name_prefix`, but I worried that doing so would increase the risk of collisions.
This update adds ALB support to the
wait_for_elb_capacity/min_elb_capacity options. Target groups are
handled in nearly the same way as Classic ELBs, so the change should be
transparent. This supports both ALB target groups and classic ELBs being
attached to the ASG at the same time.
`enabled_metrics`
Fixes#7693
The metrics_granularity parameter was not being passed to the
`EnableMetricsCollection` when we were calling it from the Update func.
this was causing the API call to silently fail and not update the
metrics for collection - unfortunately the enabled_metrics were still
being added to the state :(
By passing the granularity, we now get the correct metrics for
collection

The AWS free tier allows up to 750 hours on t2.micro
instance types. It's better to use cheaper instances
in case the resources are not cleaned up if a tests
is canceled or crashes.
Removes overspecified config that is unrelated to testing the auto scaling
group's autogenerated name. The test is only concerned with checking that
the auto scaling group was created successfully with an autogenerated name
matching a specific pattern.
Removes overspecified config that is unrelated to the auto scaling
group's availability zone and VPC identifier acceptance tests. The
created auto scaling groups do not need to spin up any hosts since
the acceptance tests are only concerned with checking the existence
of the associated availability zones and VPC identifiers.
It was a mistake to switched fully to `==` when activating waiting for
capacity on updates in #3947. Users that didn't set `min_elb_capacity ==
desired_capacity` and instead treated it as an actual "minimum" would
see timeouts for every create, since their target numbers would never be
reached exactly.
Here, we fix that regression by restoring the minimum waiting behavior
during creates.
In order to preserve all the stated behavior, I had to split out
different criteria for create and update, criteria which are now
exhaustively unit tested.
The set of fields that affect capacity waiting behavior has become a bit
of a mess. Next major release I'd like to rework all of these into a
more consistently named block of config. For now, just getting the
behavior correct and documented.
(Also removes all the fixed names from the ASG tests as I was hitting
collision issues running them over here.)
Fixes#4792
It's a bit confusing to have Terraform poll until instances come up on
ASG creation but not on update. This changes update to also poll if
min_size or desired_capacity are changed.
This changes the waiting behavior to wait for precisely the desired
number of instances instead of that number as a "minimum". I believe
this shouldn't have any undue side effects, and the behavior can still
be opted out of by setting `wait_for_capacity_timeout` to 0.
The initial commit of AWS autoscaling group termination policy was
unfinished. It only worked on "create", and so had a needless ForceNew
that would rebuild autoscaling groups on any change. It also used a
HashString set, so it didn't preserve ordering of multiple policies
correctly.
Added the "update" operation, and converted to a TypeList to preserve
ordering. In addition, removing the policy or setting it to a null list
will reset the policy to "Default", the standard AWS policy.
Updated the acceptance tests to verify the update, but the null case is
difficult to test.
This landed in aws-sdk-go yesterday, breaking the AWS provider in many places:

Here, with much sedding, grepping, and manual massaging, we attempt to
catch Terraform up to the new `awserr.Error` interface world.
On ASG creation, waits for up to 10m for desired_capacity or min_size
healthy nodes to show up in the group before continuing.
With CBD and proper HealthCheck tuning, this allows us guarantee safe
ASG replacement.
