It turns out if you're trying to write a config to conditionally restore
an instance from a snapshot, you end up painted into a corner with the
combination of `snapshot_identifier` and `name`.
You need `name` to be specified for DBs you're creating, but when
`snapshot_identifier` is populated you need it to be blank or else the
AWS API throws an error.
The logical next step is to drop a ternary in:
```tf
resource "aws_db_instance" "foo" {
# ...
snapshot_identifier = "${var.snap}"
name = "${var.snap != "" ? "" : var.dbname}"
}
```
**BUT** the above config will _replace_ the DB on subsequent runs as the
config basically has `name = ""` which will trigger a ForceNew diff once
the `name` is populated from the snapshot restore.
**SO** we can get a workable solution by actively avoiding populating
DBName when we're using one of the engines the docs explicitly mention.
It does not look like there are any tests covering `snapshot_identifer`,
so I'll subject this to some manual tests and follow up with some
results.
Sometimes when waiting on a target state, the set of valid states
through which a value will transition is unknown. This commit adds
support for an empty Pending slice and will treat any states that are not
the target as valid provided the timeouts are not exceeded.
* provider/aws: Deprecate roles in favour of role in iam_instance_profile
You can only specify a single role to an IAM Instance Profile. So having
a slice of roles in the provider makes no sense. Therefore, we are going
to deprecate this infavour of `role`

* Update iam_instance_profile.html.markdown
Adds `basename` and `dirname` interpolation. I want to add a `stack` tag to our infrastructure, the value of which is set to `${basename(path.cwd)}`. We currently use `${replace(path.cwd, "/^.+\\//", "")}` instead, but this is extremeley unreadable. The existance of a `basename` function would be very useful for this use case.
I don't have an immediate use case for a `dirname` function, but it seemed reasonable to add it as well.
According to documentation, `location` is a required argument for
`azurerm_lb_nat_pool`. However, configuring an `azurerm_lb_nat_pool`
with a `location` argument leads to the following warning:
```
There are warnings and/or errors related to your configuration. Please
fix these before continuing.
Warnings:
* azurerm_lb_nat_pool.test: "location": [DEPRECATED] location is no longer used
No errors found. Continuing with 1 warning(s).
```
Disclaimer: Terraform v0.8.8, haven't moved to 0.9.x yet :/
Fix an issue when upgrading from Terraform < 0.9 to 0.9+, when we added
support for the regional endpoints in OpsWorks Stacks. OpsWorks Stacks
can only be managed via the endpoint with which they were created, not
where the stack resides.
