terraform-null-label

what

• Remove home pages and avatars links

why

• Build-harness does it automatically

what

• Update README
• Fix make targets

why

• Some improvements and fixes
• Use / instead of : in make targets

what

• Add support for list of tag maps

why

• Certain kinds of resources (e.g. AWS AutoScaling groups) need them

what

• Use join+splat pattern in tags

why

• New Terraform versions complain if a resource with count is used in outputs without splat syntax

Terraform will now detect and warn about outputs containing potentially-problematic references to resources with count set where the references does not use the "splat" syntax. This identifies situations where an output may reference a resource with count = 0 even if the count expression does not currently evaluate to 0, allowing the bug to be detected and fixed before the value is later changed to 0 and would thus become an error. This usage will become a fatal error in Terraform 0.12. (#16735)

what

• Use join+splat pattern for outputs using resources with count

why

• New Terraform versions complain if a resource with count is used in outputs without splat syntax

Resource 'null_resource.default' not found for variable 'null_resource.default.triggers.id'

Terraform will now detect and warn about outputs containing potentially-problematic references to resources with count set where the references does not use the "splat" syntax. This identifies situations where an output may reference a resource with count = 0 even if the count expression does not currently evaluate to 0, allowing the bug to be detected and fixed before the value is later changed to 0 and would thus become an error.

What

• Fix enabled argument default value

Why

• Terraform can't compare bool with string
• It is recommended to avoid boolean values https://www.terraform.io/docs/configuration/variables.html

what

Add enabled variable which can be used to disable any resources within the module

why

If you have resources that are conditionally created and they refer to this module, your plan will always show null-label resources in the plan. As Terraform does not support conditionally including a module, this is the recommend solution

See https://github.com/hashicorp/terraform/issues/12906

what

• Validate terraform code
• Add build status badge

why

• Improve code quality/consistency

demo

depends on

• merge https://github.com/cloudposse/build-harness/pull/34
• drop git checkout from .travis.yml
