+# huaweicloud_cce_charts
+
+Use this data source to get the list of CCE charts within HuaweiCloud.

+```
+
+## Argument Reference
+
+The following arguments are supported:

+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID in UUID format.
+
+* `charts` - The list of charts.
+  The [charts](#CCE_charts) structure is documented below.
+
+<a name="CCE_charts"></a>
+The `charts` block supports:
+
+* `id` - The chart ID.
+
+* `name` - The chart name.
+
+* `values` - The values of the chart.
+
+* `translate` - The traslate source of the chart.
+
+* `instruction` - The instruction of the chart.
+
+* `version` - The chart version.
+
+* `description` - The description of the chart.
+
+* `source` - The source of the chart.
+
+* `icon_url` - The icon URL.
+
+* `public` - Whether the chart is public.
