## What As well as https://github.com/terraform-providers/terraform-provider-google/pull/1282 , make `resource_container_node_pool` importer accept `{project}/{zone}/{cluster}/{name}` format to specify the project where the node pool belongs to actually. ## Why Sometimes I want to import container pool in different project from default SA's. However, currently there is no way to specify project the target node pool belongs to, Terraform tries to retrieve node pool from SA's project, then it fails due to `You cannot import non-existent resources using Terraform import.` error.

# google\_container\_node\_pool
|
|
|
|
Manages a Node Pool resource within GKE. For more information see
|
|
[the official documentation](https://cloud.google.com/container-engine/docs/node-pools)
|
|
and
|
|
[API](https://cloud.google.com/container-engine/reference/rest/v1/projects.zones.clusters.nodePools).
|
|
|
|
## Example usage
|
|
### Standard usage
|
|
```hcl
|
|
resource "google_container_node_pool" "np" {
|
|
name = "my-node-pool"
|
|
zone = "us-central1-a"
|
|
cluster = "${google_container_cluster.primary.name}"
|
|
node_count = 3
|
|
}
|
|
|
|
resource "google_container_cluster" "primary" {
|
|
name = "marcellus-wallace"
|
|
zone = "us-central1-a"
|
|
initial_node_count = 3
|
|
|
|
additional_zones = [
|
|
"us-central1-b",
|
|
"us-central1-c",
|
|
]
|
|
|
|
master_auth {
|
|
username = "mr.yoda"
|
|
password = "adoy.rm"
|
|
}
|
|
|
|
node_config {
|
|
oauth_scopes = [
|
|
"https://www.googleapis.com/auth/compute",
|
|
"https://www.googleapis.com/auth/devstorage.read_only",
|
|
"https://www.googleapis.com/auth/logging.write",
|
|
"https://www.googleapis.com/auth/monitoring",
|
|
]
|
|
|
|
guest_accelerator {
|
|
type = "nvidia-tesla-k80"
|
|
count = 1
|
|
}
|
|
}
|
|
}
|
|
|
|
```
|
|
### Usage with an empty default pool.
|
|
```hcl
|
|
resource "google_container_node_pool" "np" {
|
|
name = "my-node-pool"
|
|
zone = "us-central1-a"
|
|
cluster = "${google_container_cluster.primary.name}"
|
|
node_count = 1
|
|
|
|
node_config {
|
|
preemptible = true
|
|
machine_type = "n1-standard-1"
|
|
|
|
oauth_scopes = [
|
|
"compute-rw",
|
|
"storage-ro",
|
|
"logging-write",
|
|
"monitoring",
|
|
]
|
|
}
|
|
}
|
|
|
|
resource "google_container_cluster" "primary" {
|
|
name = "marcellus-wallace"
|
|
zone = "us-central1-a"
|
|
|
|
lifecycle {
|
|
ignore_changes = ["node_pool"]
|
|
}
|
|
|
|
node_pool {
|
|
name = "default-pool"
|
|
}
|
|
}
|
|
|
|
```
|
|
|
|
### Usage with a regional cluster
|
|
|
|
```hcl
|
|
|
|
resource "google_container_cluster" "regional" {
|
|
name = "marcellus-wallace"
|
|
region = "us-central1"
|
|
}
|
|
|
|
resource "google_container_node_pool" "regional-np" {
|
|
name = "my-node-pool"
|
|
region = "us-central1"
|
|
cluster = "${google_container_cluster.primary.name}"
|
|
node_count = 1
|
|
}
|
|
|
|
```
|
|
|
|
## Argument Reference
|
|
|
|
* `zone` - (Optional) The zone in which the cluster resides.
|
|
|
|
* `region` - (Optional) The region in which the cluster resides (for regional clusters).
|
|
|
|
* `cluster` - (Required) The cluster to create the node pool for. Cluster must be present in `zone` provided for zonal clusters.
|
|
|
|
Note: You must be provide region for regional clusters and zone for zonal clusters
|
|
|
|
- - -
|
|
|
|
* `autoscaling` - (Optional) Configuration required by cluster autoscaler to adjust
|
|
the size of the node pool to the current cluster usage. Structure is documented below.
|
|
|
|
* `initial_node_count` - (Optional) The initial node count for the pool. Changing this will force
|
|
recreation of the resource.
|
|
|
|
* `management` - (Optional) Node management configuration, wherein auto-repair and
|
|
auto-upgrade is configured. Structure is documented below.
|
|
|
|
* `name` - (Optional) The name of the node pool. If left blank, Terraform will
|
|
auto-generate a unique name.
|
|
|
|
* `name_prefix` - (Deprecated, Optional) Creates a unique name for the node pool beginning
|
|
with the specified prefix. Conflicts with `name`.
|
|
|
|
* `node_config` - (Optional) The node configuration of the pool. See
|
|
[google_container_cluster](container_cluster.html) for schema.
|
|
|
|
* `node_count` - (Optional) The number of nodes per instance group. This field can be used to
|
|
update the number of nodes per instance group but should not be used alongside `autoscaling`.
|
|
|
|
* `project` - (Optional) The ID of the project in which to create the node pool. If blank,
|
|
the provider-configured project will be used.
|
|
|
|
* `version` - (Optional) The Kubernetes version for the nodes in this pool. Note that if this field
|
|
and `auto_upgrade` are both specified, they will fight each other for what the node version should
|
|
be, so setting both is highly discouraged.
|
|
|
|
The `autoscaling` block supports:
|
|
|
|
* `min_node_count` - (Required) Minimum number of nodes in the NodePool. Must be >=1 and
|
|
<= `max_node_count`.
|
|
|
|
* `max_node_count` - (Required) Maximum number of nodes in the NodePool. Must be >= min_node_count.
|
|
|
|
The `management` block supports:
|
|
|
|
* `auto_repair` - (Optional) Whether the nodes will be automatically repaired.
|
|
|
|
* `auto_upgrade` - (Optional) Whether the nodes will be automatically upgraded.
|
|
|
|
## Import
|
|
|
|
Node pools can be imported using the `project`, `zone`, `cluster` and `name`. If
|
|
the project is omitted, the default provider value will be used. Examples:
|
|
|
|
```
|
|
$ terraform import google_container_node_pool.mainpool my-gcp-project/us-east1-a/my-cluster/main-pool
|
|
|
|
$ terraform import google_container_node_pool.mainpool us-east1-a/my-cluster/main-pool
|
|
```
