Module Features

This module implements the following terraform resources:

google_secret_manager_secret

and supports additional features of the following modules:

mineiros-io/terraform-google-secret-manager-iam

Getting Started

Most basic usage just setting required arguments:

module "terraform-google-secret-manager" {
  source = "github.com/mineiros-io/terraform-google-secret-manager.git?ref=v0.3.0"

  secret_id = "secret"
}

Module Argument Reference

See variables.tf and examples/ for details and use-cases.

Main Resource Configuration

secret_id: (Required string)

This must be unique within the project.
replicas: (Optional list(replica))

A list of replicas for the secret will be replicated in according to the location set in the location property. If empty The Secret will automatically be replicated without any restrictions.

}
```
  The customer_managed_encryption object accepts the following attributes:
  - kms_key_name: (Required string)
    
    Describes the Cloud KMS encryption key that will be used to protect destination secret.
labels: (Optional map(string))

The labels assigned to this Secret. Label keys must be between 1 and 63 characters long, have a UTF-8 encoding of maximum 128 bytes, and must conform to the following PCRE regular expression: [\p{Ll}\p{Lo}][\p{Ll}\p{Lo}\p{N}-]{0,62} Label values must be between 0 and 63 characters long, have a UTF-8 encoding of maximum 128 bytes, and must conform to the following PCRE regular expression: [\p{Ll}\p{Lo}\p{N}-]{0,63} No more than 64 labels can be assigned to a given resource. An object containing a list of key: value pairs.

Default is {}.

Example:
```
labels = {
  "app": "web",
  "env": "prod"
}
```
expire_time: (Optional string)

Timestamp in UTC when the Secret is scheduled to expire. This is always provided on output, regardless of what was sent on input. A timestamp in RFC3339 UTC Zulu format, with nanosecond resolution and up to nine fractional digits. Examples: 2014-10-02T15:01:23Z and 2014-10-02T15:01:23.045123456Z.
ttl: (Optional string)

The TTL for the Secret. A duration in seconds with up to nine fractional digits, terminated by s. Example: 3.5s.
topics: (Optional set(string))

A list of up to 10 Pub/Sub topics to which messages are published when control plane operations are called on the secret or its versions. Structure is documented below. If you set topics, you will need to set rotation too.
rotation: (Optional object(rotation))

The rotation time and period for a Secret. At next_rotation_time, Secret Manager will send a Pub/Sub notification to the topics configured on the Secret. topics must be set to configure rotation.

Example:
```
rotation = {
  next_rotation_time = "2022-10-02T15:01:23.045123456Z"
  rotation_period    = "3600s"
}
```
The rotation object accepts the following attributes:
- next_rotation_time: (Optional string)
  
  Timestamp in UTC at which the Secret is scheduled to rotate. A timestamp in RFC3339 UTC Zulu format, with nanosecond resolution and up to nine fractional digits. Examples: 2014-10-02T15:01:23Z and 2014-10-02T15:01:23.045123456Z.
- rotation_period: (Optional string)
  
  The Duration between rotation notifications. Must be in seconds and at least 3600s (1h) and at most 3153600000s (100 years). If rotationPeriod is set, next_rotation_time must be set. next_rotation_time will be advanced by this period when the service automatically sends rotation notifications.
project: (Optional string)

The ID of the project in which the resource belongs. If it is not provided, the provider project is used.

Extended Resource Configuration

Module Versioning

This Module follows the principles of Semantic Versioning (SemVer).

Given a version number MAJOR.MINOR.PATCH, we increment the:

MAJOR version when we make incompatible changes,
MINOR version when we add functionality in a backwards compatible manner, and
PATCH version when we make backwards compatible bug fixes.

Backwards compatibility in `0.0.z` and `0.y.z` version

Backwards compatibility in versions 0.0.z is not guaranteed when z is increased. (Initial development)
Backwards compatibility in versions 0.y.z is not guaranteed when y is increased. (Pre-release)
