+# kubernetes_secret
+
+The resource provides mechanisms to inject containers with sensitive information, such as passwords, while keeping containers agnostic of Kubernetes.
+Secrets can be used to store sensitive information either as individual properties or coarse-grained entries like entire files or JSON blobs.
+The resource will by default create a secret which is available to any pod in the specified (or default) namespace.
+
+~> Read more about security properties and risks involved with using Kubernetes secrets: [Kubernetes reference](https://kubernetes.io/docs/user-guide/secrets/#security-properties)
+
+~> **Note:** All arguments including the secret data will be stored in the raw state as plain-text. [Read more about sensitive data in state](/docs/state/sensitive-data.html).
+
+## Example Usage
+
+```hcl
+data "kubernetes_secret" "example" {
+  metadata {
+    name = "basic-auth"
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `metadata` - (Required) Standard secret's metadata. For more info see [Kubernetes reference](https://github.com/kubernetes/community/blob/e59e666e3464c7d4851136baa8835a311efdfb8e/contributors/devel/api-conventions.md#metadata)
+
+## Nested Blocks
+
+### `metadata`
+
+#### Arguments
+
+* `name` - (Required) Name of the secret, must be unique. For more info see [Kubernetes reference](http://kubernetes.io/docs/user-guide/identifiers#names)
+* `namespace` - (Optional) Namespace defines the space within which name of the secret must be unique.
+
+#### Attributes
+
+* `generation` - A sequence number representing a specific generation of the desired state.
+* `resource_version` - An opaque value that represents the internal version of this secret that can be used by clients to determine when secret has changed. For more info see [Kubernetes reference](https://github.com/kubernetes/community/blob/e59e666e3464c7d4851136baa8835a311efdfb8e/contributors/devel/api-conventions.md#concurrency-control-and-consistency)
+* `self_link` - A URL representing this secret.
+* `uid` - The unique in time and space value for this secret. For more info see [Kubernetes reference](http://kubernetes.io/docs/user-guide/identifiers#uids)
+
+## Attribute Reference
+
+* `data` - A map of the secret data.
+* `type` - The secret type. Defaults to `Opaque`. For more info see [Kubernetes reference](https://github.com/kubernetes/community/blob/c7151dd8dd7e487e96e5ce34c6a416bb3b037609/contributors/design-proposals/auth/secrets.md#proposed-design)
