If not suppling the `availability_zones`, they will be computed
(meaning an update/refresh will retrieve the info and update the values
to the state file).
So without the `Computed = true` the diff will always flag this as a
change, even when it’s not.
Some instance types have a block device by default. So when selecting
such an instance type, you will not set a config for the block device,
but the update/refresh func will notice one and update the state
nonetheless.
So in those cases the `block_device` becomes a `computed` field.
1. The schema contained a few fields that where not marked as
`computed`, while they were updated inside the resource.
2. While updating the `volume_size` it was doing so with a `string`,
but in the schema this field is set as `int`.
3. The set func for calculating the hashes for the `block` set items,
also used computed values to calculate the hash. As these values will
not be in the config, but only in the state, this will always show as a
diff. The solution is to only use the fields that aren’t computed in
order to get consistent hashes.
These where all issues before, but weren’t visible as such. All should
be good again now.
For now this only supports importing a key pair (by specifying a
public_key) property. In the future it'd be fairly trivial to support
key pair creation, with the private key returned as a computed property.
In real world usage you'd probably want to provide that public_key
property via a variable rather than hard-coding it into a terraform
config that'd end up in source control.

There was an error in the goamz package the prevented updating the
availability zones correctly. So PR #181 should be merged before this
one can be merged…
By using a set for the availability zones, you can use things like
`availability_zones = ["${aws_instance.web.*.availability_zone}"]`
where is very likely multiple of the same zones will be added to the
set. If you use a list here, the list will say it’s changed (even if
you add the same zone) which will force a new resource.
The resource is build so it can attach and detach the Internet Gateway
from a VPC, but as the schema has `Required` and `ForceNew` both set
to `true` for the vpc_id field it will never use these capabilities.
This is a refactored solution for PR #616. Functionally this is still
the same change, but it’s implemented a lot cleaner with less code and
less changes to existing parts of TF.
Running the tests without these changes results in this error first:
```
--- FAIL: TestAccAWSNetworkAclsOnlyIngressRulesChange (24.92 seconds)
testing.go:121: Step 0 error: Check failed: Invalid number of ingress
entries found; count = %!s(int=3)
FAIL
exit status 1
FAIL github.com/hashicorp/terraform/builtin/providers/aws 24.974s
```
And after fixing that one you also get a few unexpected values due to
an expected order mismatch between the items in the set versus the
items in the config.
Those are also fixed, so the test is passing now.
Otherwise it is impossible to get simple configurations with the
"default" routing table, which is only the "local" route.
The following contents of main.tf expose the bug, and boots an instance
fine after this patch is applied:
variable aws_access_key {}
variable aws_secret_key {}
variable aws_ubuntu_ami {}
provider "aws" {
access_key = "${var.aws_access_key}"
secret_key = "${var.aws_secret_key}"
region = "us-east-1"
}
resource "aws_vpc" "default" {
cidr_block = "10.0.0.0/20"
}
resource "aws_route_table" "private" {
vpc_id = "${aws_vpc.default.id}"
# Note the lack of "route" sub-key here.
}
resource "aws_subnet" "private" {
vpc_id = "${aws_vpc.default.id}"
cidr_block = "10.0.1.0/24"
}
resource "aws_route_table_association" "private" {
subnet_id = "${aws_subnet.private.id}"
route_table_id = "${aws_route_table.private.id}"
}
# Demonstrate an instance can be booted fine in this fashion.
resource "aws_instance" "sample" {
ami = "${var.aws_ubuntu_ami}"
instance_type = "t2.micro"
subnet_id = "${aws_subnet.private.id}"
}
terraform.tfvars for completeness:
aws_access_key = "..."
aws_secret_key = "..."
# A public Trusty AMI
aws_ubuntu_ami = "ami-9aaa1cf2"

Prior to this, the diff only contained changed set elements. The issue
with this is that `getSet`, the internal function that reads a set from
the ResourceData, expects that each level (state, config, diff, etc.)
has the _full set_ information. This change was done to fix merging
issues.
Because of this, we need to make sure the full set is visible in the
diff.
