# Configuring Vault Helm with Terraform

Terraform may also be used to configure and deploy the Vault Helm chart, by using the [Helm provider](https://registry.terraform.io/providers/hashicorp/helm/latest/docs).

For example, to configure the chart to deploy [HA Vault with integrated storage (raft)](/docs/platform/k8s/helm/examples/ha-with-raft), the values overrides can be set on the command-line, in a values yaml file, or with a Terraform configuration:

<CodeTabs>
<CodeBlockConfig>

```shell-session
$ helm install vault hashicorp/vault \
  --set='server.ha.enabled=true' \
  --set='server.ha.raft.enabled=true'
```

</CodeBlockConfig>

<CodeBlockConfig>

```yaml
server:
  ha:
    enabled: true
    raft:
      enabled: true
```

</CodeBlockConfig>

<CodeBlockConfig>

```hcl
provider "helm" {
  kubernetes {
    config_path = "~/.kube/config"
  }
}

resource "helm_release" "vault" {
  name       = "vault"
  repository = "https://helm.releases.hashicorp.com"
  chart      = "vault"

  set {
    name  = "server.ha.enabled"
    value = "true"
  }
  set {
    name  = "server.ha.raft.enabled"
    value = "true"
  }
}
```

</CodeBlockConfig>
</CodeTabs>

The values file can also be used directly in the Terraform configuration with the [`values` directive](https://registry.terraform.io/providers/hashicorp/helm/latest/docs/resources/release#values#values).

## Further Examples

### Vault config as a multi-line string

<CodeTabs>
<CodeBlockConfig>

```yaml
server:
  ha:
    enabled: true
    raft:
      enabled: true
      setNodeId: true
      config: |
        ui = false

        listener "tcp" {
          tls_disable = 1
          address = "[::]:8200"
          cluster_address = "[::]:8201"
        }

        storage "raft" {
          path    = "/vault/data"
        }

        service_registration "kubernetes" {}

        seal "awskms" {
          region     = "us-west-2"
          kms_key_id = "alias/my-kms-key"
        }
```

</CodeBlockConfig>
<CodeBlockConfig>

```hcl
resource "helm_release" "vault" {
  name       = "vault"
  repository = "https://helm.releases.hashicorp.com"
  chart      = "vault"

  set {
    name  = "server.ha.enabled"
    value = "true"
  }
  set {
    name  = "server.ha.raft.enabled"
    value = "true"
  }
  set {
    name  = "server.ha.raft.setNodeId"
    value = "true"
  }
  set {
    name  = "server.ha.raft.config"
    value = <<EOT
ui = false

listener "tcp" {
  tls_disable = 1
  address = "[::]:8200"
  cluster_address = "[::]:8201"
}

storage "raft" {
  path    = "/vault/data"
}

service_registration "kubernetes" {}

seal "awskms" {
  region     = "us-west-2"
  kms_key_id = "alias/my-kms-key"
}
EOT
  }
}

### Lists of volumes and volumeMounts

<CodeTabs>
<CodeBlockConfig>

```yaml
server:
  volumes:
    - name: userconfig-my-gcp-iam
      secret:
        defaultMode: 420
        secretName: my-gcp-iam

  volumeMounts:
    - mountPath: /vault/userconfig/my-gcp-iam
      name: userconfig-my-gcp-iam
      readOnly: true
```

</CodeBlockConfig>

<CodeBlockConfig>

```hcl
resource "helm_release" "vault" {
  name       = "vault"
  repository = "https://helm.releases.hashicorp.com"
  chart      = "vault"

  set {
    name  = "server.volumes[0].name"
    value = "userconfig-my-gcp-iam"
  }
  set {
    name  = "server.volumes[0].secret.defaultMode"
    value = "420"

  set {
    name  = "server.volumes[0].secret.secretName"
    value = "my-gcp-iam"
  }

  set {
    name  = "server.volumeMounts[0].mountPath"
    value = "/vault/userconfig/my-gcp-iam"

  set {
    name  = "server.volumeMounts[0].name"
    value = "userconfig-my-gcp-iam"
  }
  set {
    name  = "server.volumeMounts[0].readOnly"
    value = "true"
  }
}
```

### Annotations

Annotations can be set as a YAML map:

<CodeTabs>

<CodeBlockConfig>

```yaml
server:
  ingress:
    annotations:
      service.beta.kubernetes.io/azure-load-balancer-internal: true
      service.beta.kubernetes.io/azure-load-balancer-internal-subnet: apps-subnet
```
</CodeBlockConfig>

<CodeBlockConfig>

```hcl
  set {
    name = "server.ingress.annotations.service\\.beta\\.kubernetes\\.io/azure-load-balancer-internal"
    value = "true"
  }

  set {
    name = "server.ingress.annotations.service\\.beta\\.kubernetes\\.io/azure-load-balancer-internal-subnet"
    value = "apps-subnet"
  }
```

</CodeBlockConfig>
</CodeTabs>

or as a multi-line string:

<CodeTabs>
<CodeBlockConfig>

```yaml
server:
  ingress:
    annotations: |
      service.beta.kubernetes.io/azure-load-balancer-internal: true
      service.beta.kubernetes.io/azure-load-balancer-internal-subnet: apps-subnet
```

</CodeBlockConfig>
<CodeBlockConfig>

```hcl
  set {
    name = "server.ingress.annotations"
    value = yamlencode({
      "service.beta.kubernetes.io/azure-load-balancer-internal": "true"
      "service.beta.kubernetes.io/azure-load-balancer-internal-subnet": "apps-subnet"
    })
    type = "auto"
  }
```
