Update the Google Compute Engine provider to add support for service
accounts on `google_compute_instance`. Both gcloud shorthand (`compute-ro`,
`storage-ro`, etc.) and OAuth2 API endpoints are supported.
This feature is currently limited to a single service account (supporting
multiple scopes) and an automatically-generated service account email.
`go get -u` now checks that remote repo paths match the ones predicted
by the import paths.
So if working on TF from a forked repo, you cannot use `updatedeps` as
`go get` will complain about the differences between the import and the
path to your fork.
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.
