allows load balancer policies and their assignment to backend servers or listeners to be configured independently.
this gives flexibility to configure additional policies on aws elastic load balancers aside from the already provided "convenience" wrappers for cookie stickiness
This resource (unlike the others in this provider) isn't stateful, so it
is a good candidate to be a data source.
The old resource form is preserved via the standard shim in helper/schema,
which will generate a deprecation warning but will still allow the
resource to be used.
When applying or removing 2+ security groups from an instance, an EOF
error will be triggered even though the action was successful. This
patch accounts for and ignores the EOF error. It also adds a test
case.
Security Group and Port documentation are also updated in this
commit.
When refreshing remote state, indicate when no state file was found with
an ErrRemoteStateNotFound error. This prevents us from inadvertantly
getting a nil state into a terraform.State where we assume there's
always a root module.
When working from an existing plan, we weren't setting the PathOut field
for a LocalState. This required adding an outPath argument to the
StateFromPlan function to avoid having to introspect the returned
state.State interface to find the appropriate field.
To test we run a plan first and provide the new plan to apply with
`-state-out` set.
In #7170 we found two scenarios where the type checking done during the
`context.Validate()` graph walk was circumvented, and the subsequent
assumption of type safety in the provider's `Diff()` implementation
caused panics.
Both scenarios have to do with interpolations that reference Computed
values. The sentinel we use to indicate that a value is Computed does
not carry any type information with it yet.
That means that an incorrect reference to a list or a map in a string
attribute can "sneak through" validation only to crop up...
1. ...during Plan for Data Source References
2. ...during Apply for Resource references
In order to address this, we:
* add high-level tests for each of these two scenarios in `provider/test`
* add context-level tests for the same two scenarios in `terraform`
(these tests proved _really_ tricky to write!)
* place an `EvalValidateResource` just before `EvalDiff` and `EvalApply` to
catch these errors
* add some plumbing to `Plan()` and `Apply()` to return validation
errors, which were previously only generated during `Validate()`
* wrap unit-tests around `EvalValidateResource`
* add an `IgnoreWarnings` option to `EvalValidateResource` to prevent
active warnings from halting execution on the second-pass validation
Eventually, we might be able to attach type information to Computed
values, which would allow for these errors to be caught earlier. For
now, this solution keeps us safe from panics and raises the proper
errors to the user.
Fixes#7170
I noticed we had two mechanisms for unit test override. One that dropped
a sentinel into the env var, and another with a struct member on
TestCase. This consolidates the two, using the cleaner struct member
internal mechanism and the nicer `resource.UnitTest()` entry point.
* small doc update
* provider/atlas: Add docs for Artifact Data Source
* provider/atlas: Remove a test method that isn't used
* provider/atlas: Add Data Source for Atlas Artifact
* provider/atlas: Show deprecation error on atlas_artifact resource
Fixes#7374
The introduction of the AzureRM SDK 3.0.0-beta means that the
`name_servers` for the DNS Zone are returned from the API

This test function tests both VPC and Classic EC2 modes, but not
all accounts have support for both. Splitting them makes it
easier to understand why a test fails when an account only
supports the VPC mode.
