!> **Warning:** Due to limitations of the API, all arguments except
`node_version` are non-updateable. Changing any will cause recreation of the
whole cluster!

## Example usage
```js
2015-06-21 00:57:45 +02:00
resource "google_container_cluster" "primary" {
name = "marcellus-wallace"
zone = "us-central1-a"
initial_node_count = 3
additional_zones = [
"us-central1-b",
"us-central1-c"
]
master_auth {
username = "mr.yoda"
password = "adoy.rm"
}
node_config {
oauth_scopes = [
"https://www.googleapis.com/auth/compute",
"https://www.googleapis.com/auth/devstorage.read_only",
"https://www.googleapis.com/auth/logging.write",
"https://www.googleapis.com/auth/monitoring"
]
}

}
```
## Argument Reference
* `initial_node_count` - (Required) The number of nodes to create in this
cluster (not including the Kubernetes master).
* `master_auth` - (Required) The authentication information for accessing the
Kubernetes master.
* `name` - (Required) The name of the cluster, unique within the project and
zone.
* `zone` - (Required) The zone that the master and the number of nodes specified
in `initial_node_count` should be created in.
- - -
* `additional_zones` - (Optional) If additional zones are configured, the number
of nodes specified in `initial_node_count` is created in all specified zones.
2016-11-15 00:49:43 +01:00
* `addons_config` - (Optional) The configuration for addons supported by Google
Container Engine
* `cluster_ipv4_cidr` - (Optional) The IP address range of the container pods in
this cluster. Default is an automatically assigned CIDR.
* `description` - (Optional) Description of the cluster.
* `logging_service` - (Optional) The logging service that the cluster should
write logs to. Available options include `logging.googleapis.com` and
`none`. Defaults to `logging.googleapis.com`
* `monitoring_service` - (Optional) The monitoring service that the cluster
should write metrics to. Available options include
`monitoring.googleapis.com` and `none`. Defaults to
`monitoring.googleapis.com`
2016-11-15 00:49:43 +01:00
* `network` - (Optional) The name or self_link of the Google Compute Engine
network to which the cluster is connected
* `node_config` - (Optional) The machine type and image to use for all nodes in
this cluster
* `node_version` - (Optional) The Kubernetes version on the nodes. Also affects
the initial master version on cluster creation. Updates affect nodes only.
Defaults to the default version set by GKE which is not necessarily the latest
version.
* `project` - (Optional) The project in which the resource belongs. If it
is not provided, the provider project is used.
2015-06-21 00:57:45 +02:00
2016-11-15 00:49:43 +01:00
* `subnetwork` - (Optional) The name of the Google Compute Engine subnetwork in
which the cluster's instances are launched
2015-06-21 00:57:45 +02:00
**Master Auth** supports the following arguments:
* `password` - The password to use for HTTP basic authentication when accessing
the Kubernetes master endpoint
* `username` - The username to use for HTTP basic authentication when accessing
the Kubernetes master endpoint
2015-06-21 00:57:45 +02:00
**Node Config** supports the following arguments:
* `machine_type` - (Optional) The name of a Google Compute Engine machine type.
Defaults to `n1-standard-1`.
* `disk_size_gb` - (Optional) Size of the disk attached to each node, specified
in GB. The smallest allowed disk size is 10GB. Defaults to 100GB.
* `oauth_scopes` - (Optional) The set of Google API scopes to be made available
on all of the node VMs under the "default" service account. These can be
either FQDNs, or scope aliases. The following scopes are necessary to ensure
the correct functioning of the cluster:
* `compute-rw` (`https://www.googleapis.com/auth/compute`)
* `storage-ro` (`https://www.googleapis.com/auth/devstorage.read_only`)
* `logging-write` (`https://www.googleapis.com/auth/logging.write`),
if `logging_service` points to Google
* `monitoring` (`https://www.googleapis.com/auth/monitoring`),
if `monitoring_service` points to Google

* `horizontal_pod_autoscaling` - (Optional) The status of the Horizontal Pod
Autoscaling addon. It is enabled by default; set `disabled = true` to
disable.
This example `addons_config` disables both addons:
```
addons_config {
2016-11-15 00:49:43 +01:00
http_load_balancing {
disabled = true
}
horizontal_pod_autoscaling {
disabled = true
}
}
```
