s3.GetBucketTagging returns an error if there are no tags associated
with a bucket. Consequently, any configuration with a tagless s3 bucket
would fail with an error, "the TagSet does not exist".
Handle that error more appropriately, interpreting it as an empty set of
tags.
The `getFirstNetworkID` does not work correctly because the first
network is not always the private network of the instance.
As long as the `GET /networks` gives a list containing also public
networks we don't have any guarantee that the first network is the
one we want. Furthermore, with a loop over the network list we are
not able to determine which network is the one we want.
Instead of retrieving the network ID and then finding the port ID,
it's better to basically take the first port ID of the instance.
Only used in targets for now. The plan is to use this for interpolation
as well.
This allows us to target:
* individual resources expanded by `count` using bracket / index notation.
* deposed / tainted resources with an `InstanceType` field after name
Docs to follow.
Add `-target=resource` flag to core operations, allowing users to
target specific resources in their infrastructure. When `-target` is
used, the operation will only apply to that resource and its
dependencies.
The calculated dependencies are different depending on whether we're
running a normal operation or a `terraform destroy`.
Generally, "dependencies" refers to ancestors: resources falling
_before_ the target in the graph, because their changes are required to
accurately act on the target.
For destroys, "dependencies" are descendents: those resources which fall
_after_ the target. These resources depend on our target, which is going
to be destroyed, so they should also be destroyed.
