# Upgrading to v18.0 | ||
|
||
The v18.0 release of *kubernetes-engine* is a backwards incompatible release. | ||
|
||
### Google Cloud Platform Provider upgrade | ||
The Terraform Kubernetes Engine Module now requires version 4.0 or higher of | ||
the Google Cloud Platform Provider. | ||
|
||
```diff | ||
terraform { | ||
required_providers { | ||
google = { | ||
source = "hashicorp/google" | ||
- version = "~> 3.0" | ||
+ version = "~> 4.0" | ||
} | ||
google-beta = { | ||
source = "hashicorp/google-beta" | ||
- version = "~> 3.0" | ||
+ version = "~> 4.0" | ||
} | ||
|
||
} | ||
} | ||
``` | ||
|
||
### Kubernetes Basic Authentication removed | ||
Basic authentication is deprecated and has been removed in GKE 1.19 and later. | ||
Owing to this, the `basic_auth_username` and `basic_auth_password` variables | ||
have been eliminated. | ||
|
||
```diff | ||
module "gke" { | ||
source = "terraform-google-modules/kubernetes-engine/google//modules/private-cluster" | ||
- version = "~> 17.0" | ||
+ version = "~> 18.0" | ||
|
||
- basic_auth_username = "admin" | ||
- basic_auth_password = "s3crets!" | ||
} | ||
``` | ||
|
||
### Acceptable values for node_metadata modified | ||
It is recommended to update `node_metadata` variable to one of `GKE_METADATA`, | ||
`GCE_METADATA` or `UNSPECIFIED`. `GKE_METADATA` replaces the previous | ||
`GKE_METADATA_SERVER` value, `GCE_METADATA` should be used in place of | ||
`EXPOSE`, however old values continue to be supported for backwards compatibility. | ||
The `SECURE` option, previously deprecated, has now been removed. | ||
|
||
```diff | ||
module "gke" { | ||
source = "../../modules/safer-cluster" | ||
|
||
node_pools = [ | ||
{ | ||
|
||
- node_metadata = "GKE_METADATA_SERVER" | ||
+ node_metadata = "GKE_METADATA" | ||
} | ||
] | ||
} | ||
``` | ||
|
||
### node_pools_versions is now keyed by node-pool name | ||
The `node_pools_versions` output is now an object keyed by node pool name, | ||
rather than a list as previously. |
