+# hcp_packer_channel (Resource)
+
+The Packer Channel resource allows you to manage image bucket channels within an active HCP Packer Registry.
+
+## Example Usage
+
+To create a channel with no assigned iteration.
+```terraform
+resource "hcp_packer_channel" "staging" {
+  name        = "staging"
+  bucket_name = "alpine"
+}
+```
+
+To create, or update an existing, channel with an assigned iteration.
+```terraform
+resource "hcp_packer_channel" "staging" {
+  name        = "staging"
+  bucket_name = "alpine"
+  iteration {
+    id = "iteration-id"
+  }
+}
+
+# Update assigned iteration using an iteration fingerprint
+resource "hcp_packer_channel" "staging" {
+  name        = "staging"
+  bucket_name = "alpine"
+  iteration {
+    fingerprint = "fingerprint-associated-to-iteration"
+  }
+}
+
+# Update assigned iteration using an iteration incremental version
+resource "hcp_packer_channel" "staging" {
+  name        = "staging"
+  bucket_name = "alpine"
+  iteration {
+    // incremental_version is the version number assigned to a completed iteration.
+    incremental_version = 1
+  }
+}
+```
+
+Using the latest channel to create a new channel with an assigned iteration.
+```terraform
+data "hcp_packer_image_iteration" "latest" {
+  bucket_name = "alpine"
+  channel     = "latest"
+}
+
+resource "hcp_packer_channel" "staging" {
+  name        = staging
+  bucket_name = alpine
+  iteration {
+    id = data.hcp_packer_image_iteration.latest.id
+  }
+}
+```
+
+
+<!-- schema generated by tfplugindocs -->
+## Schema
+
+### Required
+
+- `bucket_name` (String) The slug of the HCP Packer Registry image bucket where the channel should be managed in.
+- `name` (String) The name of the channel being managed.
+
+### Optional
+
+- `iteration` (Block List, Max: 1) The iteration assigned to the channel. (see [below for nested schema](#nestedblock--iteration))
+- `timeouts` (Block, Optional) (see [below for nested schema](#nestedblock--timeouts))
+
+### Read-Only
+
+- `author_id` (String) The author of the channel.
+- `created_at` (String) Creation time of this build.
+- `id` (String) The ID of this resource.
+- `organization_id` (String) The ID of the organization this HCP Packer registry is located in.
+- `project_id` (String) The ID of the project this HCP Packer registry is located in.
+- `updated_at` (String) The author of the channel.
+
+<a id="nestedblock--iteration"></a>
+### Nested Schema for `iteration`
+
+Optional:
+
+- `fingerprint` (String) The fingerprint of the iteration assigned to the channel.
+- `id` (String) The ID of the iteration assigned to the channel.
+- `incremental_version` (Number) The incremental_version of the iteration assigned to the channel.
+
+
+<a id="nestedblock--timeouts"></a>
+### Nested Schema for `timeouts`
+
+Optional:
+
+- `create` (String)
+- `default` (String)
+- `delete` (String)
+- `update` (String)
+
+## Import
+
+Import is supported using the following syntax:
+
+```shell
+# The import ID requires the bucket and channel name in the following format {bucket_name}:{name}
+terraform import hcp_packer_channel.staging alpine:staging
