The render code path in `template_file` was doing unsynchronized access
to a shared mapping of functions in `config.Func`.
This caused a race condition that was most often triggered when a
`template_file` had a `count` of more than one, and expressed itself as
a panic in the plugin followed by a cascade of "unexpected EOF" errors
through the plugin system.
Here, we simply turn the FuncMap from shared state into a generated
value, which avoids the race. We do more re-initialization of the data
structure, but the performance implications are minimal, and we can
always revisit with a perf pass later now that the race is fixed.
This adds acceptance tests for specifying extra hosts on Docker
containers. It also renames the repeating block from `hosts` to `host`,
which reads more naturally in the schema when multiple instances of the
block are declared.
When a Packet provision exceeds our time limit, we move the device to an
internal project for Packet staff to investigate. When this happens, the
original user no longer has access to the device, and they get a 403.
These changes make that and other external state changes more pleasant for
users of Terraform.
This allows specification of the profile for the shared credentials
provider for AWS to be specified in Terraform configuration. This is
useful if defining providers with aliases, or if you don't want to set
environment variables. Example:
$ aws configure --profile this_is_dog
... enter keys
$ cat main.tf
provider "aws" {
profile = "this_is_dog"
# Optionally also specify the path to the credentials file
shared_credentials_file = "/tmp/credentials"
}
This is equivalent to specifying AWS_PROFILE or
AWS_SHARED_CREDENTIALS_FILE in the environment.
Asserting on the value of `latest` on an image is prone to failing
because of new images being pushed upstream. Instead of asserting on a
hash, we assert that the value matches a regular expression for the
format of an image hash.
