# Terraform Module - Rancher

Sets up a Rancher (Platform for Kubernetes Management) cluster on top of OpenStack.

For an overview of the options, checkout [variables.tf](./variables.tf)

## Example

```terraform

resource "openstack_compute_keypair_v2" "rancher_cluster" {

  name = "rancher-cluster"

}

module "rancher" {

  source = "git::https://github.com/nimbolus/tf-rancher.git?ref=v0.7.0"

  cluster_availability_zone   = "nova"

  cluster_image_name          = "ubuntu-20.04"

  cluster_key_pair            = openstack_compute_keypair_v2.rancher_cluster.name

  cluster_server_group_policy = "anti-affinity"

  cluster_network_id          = data.openstack_networking_network_v2.rancher.id

  cluster_subnet_id           = data.openstack_networking_subnet_v2.rancher.id

  rancher_hostname            = "rancher.example.com"

}

output "rancher_cluster_kubeconfig" {

  value     = module.rancher.kubeconfig

  sensitive = true

}

provider "rancher2" {

  alias = "bootstrap"

  api_url   = "https://rancher.example.com"

  bootstrap = true

}

resource "rancher2_bootstrap" "admin" {

  provider = rancher2.bootstrap

  current_password = module.rancher.rancher_bootstrap_password

  password         = module.rancher.rancher_bootstrap_password

  telemetry        = false

}

provider "rancher2" {

  api_url   = rancher2_bootstrap.admin.url

  token_key = rancher2_bootstrap.admin.token

}

module "rancher_sa_test" {

  source = "git::https://github.com/nimbolus/tf-rancher.git//service-account?ref=v0.7.0"

  name  = "test"

  email = "[email protected]"

}

```

## Upgrade Notes

### v0.7.0

Upgrade to `v0.6.1` first and migrate kubectl provider resources if needed:

```sh

tofu state rm module.rancher.kubectl_manifest.cluster_issuer

tofu state rm module.rancher.kubectl_manifest.rancher_certificate

tofu import 'module.rancher.kubernetes_manifest.cluster_issuer[0]' \

  "apiVersion=cert-manager.io/v1kind=ClusterIssuser,name=letsencrypt"

tofu import 'module.rancher.kubernetes_manifest.rancher_certificate[0]' \

  "apiVersion=cert-manager.iov1,kind=Certificate,namespace=cattle-system,name=rancher"

```

Then upgrade to `v0.7.0`
