When an error is passed, the FileInfo can be nil, which was previously
causing a crash on trying to evaluate f.IsDir(). By checking for an error
first we avoid this crash.
When TerraForm is used to configure and deploy infrastructure
applications that require dozens templated files, such as Kubernetes, it
becomes extremely burdensome to template them individually: each of them
requires a data source block as well as an upload/export (file
provisioner, AWS S3, ...).
Instead, this commit introduces a mean to template an entire folder of
files (recursively), that can then be treated as a whole by any provider
or provisioner that support directory inputs (such as the
file provisioner, the archive provider, ...).
This does not intend to make TerraForm a full-fledged templating system
as the templating grammar and capabilities are left unchanged. This only
aims at improving the user-experience of the existing templating
provider by significantly reducing the overhead when several files are
to be generated - without forcing the users to rely on external tools
when these templates stay simple and that their generation in TerraForm
is justified.
The backend apply operation doesn't need to output the same text as the
cli itself. Instead notify the user that we are in the process of
stopping the operation.
This is the minimal amount of work needed to be able to create a list of a subset of subnet IDs in a VPC, allowing people to loop through them easily when creating EC2 instances or provide a list straight to an ELB.
Fixes: #13588
It was pointed out in #13588 that we don't need to ForceNew on a change
of IPv6 CIDR block. The logic I decided to implement here was to
disassociate then associate. We should only be able to be associated to
1 IPv6 CIDR block at once. This feels like a risky move. We can
disassociate and then error on the associate. This would leave us in a
situation where we have no IPv6 CIDR block associated
The alternative here would be that the failure of association, triggers
a reassociation with the old IPv6 CIDR block
I added a test to make sure that the subnet Ids don't change as the ipv6
block changes. Before removing the ForceNew from the ipv6_cidr_block,
the test results in the following:
```
=== RUN TestAccAWSSubnet_ipv6
--- FAIL: TestAccAWSSubnet_ipv6 (92.09s)
resource_aws_subnet_test.go:105: Expected SubnetIDs not to change, but both got before: subnet-0d2b6a6a and after: subnet-742c6d13
```
After the removal of ForceNew, the test result looks as follows:
```
=== RUN TestAccAWSSubnet_ipv6
--- PASS: TestAccAWSSubnet_ipv6 (188.34s)
```
```

* added .travis.yml and deploy.sh
* added deploy script, updated travis.yml to build topic- branches
* generate random string for hostname
* plan now produces output plan, apply now consumes outputted plan
* cleanup; sane defaults
* explicit build dirs
Many apps deployed to Heroku require that multiple buildpacks be
configured in a particular order to operate correctly.
This updates the builtin Heroku provider's app resource to support
configuring buildpacks and the related documentation in the website.
Similar to config vars, externally set buildpacks will not be altered if
the config is not set.
