From 86e845033dfc288364a64795b5145753f4dde95d Mon Sep 17 00:00:00 2001 From: Nuru Date: Sun, 13 Oct 2024 09:46:34 -0700 Subject: [PATCH] [vpc] Add `max_nats` configuration (https://github.com/cloudposse/terraform-aws-components/pull/1158) --- src/README.md | 1 + src/main.tf | 1 + src/variables.tf | 10 ++++++++++ 3 files changed, 12 insertions(+) diff --git a/src/README.md b/src/README.md index cc9d93b..c14ee78 100644 --- a/src/README.md +++ b/src/README.md @@ -125,6 +125,7 @@ components: | [label\_value\_case](#input\_label\_value\_case) | Controls the letter case of ID elements (labels) as included in `id`,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the `tags` input.
Possible values: `lower`, `title`, `upper` and `none` (no transformation).
Set this to `title` and set `delimiter` to `""` to yield Pascal Case IDs.
Default value: `lower`. | `string` | `null` | no | | [labels\_as\_tags](#input\_labels\_as\_tags) | Set of labels (ID elements) to include as tags in the `tags` output.
Default is to include all labels.
Tags with empty values will not be included in the `tags` output.
Set to `[]` to suppress all generated tags.
**Notes:**
The value of the `name` tag, if included, will be the `id`, not the `name`.
Unlike other `null-label` inputs, the initial setting of `labels_as_tags` cannot be
changed in later chained modules. Attempts to change it will be silently ignored. | `set(string)` |

Usually the component or solution name, e.g. 'app' or 'jenkins'.
This is the only ID element not also included as a `tag`.
The "name" tag is set to the full `id` string. There is no tag with the value of the `name` input. | `string` | `null` | no | | [namespace](#input\_namespace) | ID element.
