# Vault Enterprise License Management

You can use this Helm chart to deploy Vault Enterprise by following a few extra steps around licensing.

~> **Note:** As of Vault Enterprise 1.8, the license must be specified via HCL configuration or environment variables on startup, unless the Vault cluster was created with an older Vault version and the license was stored, or the Vault Enterprise binary has the license baked in (`prem` or `pro` version tags). More information is available in the [Vault Enterprise License docs](/docs/enterprise/license).

## Vault Enterprise 1.8+

### License Install

First create a Kubernetes secret using the contents of your license file. For example, the following commands create a secret with the name `vault-ent-license` and key `license`:

```bash
secret=$(cat 1931d1f4-bdfd-6881-f3f5-19349374841f.hclic)
kubectl create secret generic vault-ent-license --from-literal="license=${secret}"
```

-> **Note:** If you cannot find your `.hclic` file, please contact your sales team or Technical Account Manager.

In your chart overrides, set the values of [`server.image`](/docs/platform/k8s/helm/configuration#image-2) to one of the enterprise [release tags](https://hub.docker.com/r/hashicorp/vault-enterprise/tags). Also set the name of the secret you just created in [`server.enterpriseLicense`](/docs/platform/k8s/helm/configuration#enterpriselicense).

```yaml
# config.yaml
server:
  image:
    repository: hashicorp/vault-enterprise
    tag: 1.9.0_ent
  enterpriseLicense:
    secretName: vault-ent-license
```

Now run `helm install`:

```shell-session
$ helm install hashicorp hashicorp/vault -f config.yaml
```

Once the cluster is [initialized and unsealed](/docs/platform/k8s/helm/run), you may check the license status using the `vault license get` command:

```shell
kubectl exec -ti vault-0 -- vault license get
```

### License Update

To update the autoloaded license in Vault, you may do the following:

- Update your license secret with the new license data

```shell
new_secret=$(base64 < ./new-license.hclic | tr -d '\n')

cat > patch-license.yaml <<EOF
data:
  license: ${new_secret}
EOF

kubectl patch secret vault-ent-license --patch "$(cat patch-license.yaml)"
```

- Wait until [`vault license inspect`](/docs/commands/license/inspect) shows the updated license

  Since the `inspect` command is reading the license file from the mounted secret, this tells you when the updated secret has been propagated to the mount on the Vault pod.

```shell
kubectl exec vault-0 -- vault license inspect
```

- Reload Vault's license config

  You may use the [`sys/config/reload/license` API endpoint](/api-docs/system/config-reload#reload-license-file):

```shell
kubectl exec vault-0 -- vault write -f sys/config/reload/license
```

  Or you may issue an HUP signal directly to Vault:

```shell
kubectl exec vault-0 -- pkill -HUP vault
```

- Verify that [`vault license get`](/docs/commands/license/get) shows the updated license

```shell
kubectl exec vault-0 -- vault license get
```

## Vault Enterprise prior to 1.8

In your chart overrides, set the values of `server.image` to one of the enterprise [release tags](https://hub.docker.com/r/hashicorp/vault-enterprise/tags). Install the chart, and initialize and unseal vault as described in [Running Vault](/docs/platform/k8s/helm/run).

After Vault has been initialized and unsealed, setup a port-forward tunnel to the Vault Enterprise cluster:

```shell
kubectl port-forward vault-0 8200:8200
```

Next, in a separate terminal, create a `payload.json` file that contains the license key like this example:

```json
{
  "text": "01ABCDEFG..."
}
```

Finally, using curl, apply the license key to the Vault API:

```bash
curl \
  --header "X-Vault-Token: VAULT_LOGIN_TOKEN_HERE" \
  --request PUT \
  --data @payload.json \
  http://127.0.0.1:8200/v1/sys/license

```

To verify that the license installation worked correctly, using `curl`, run the following:

```shell
curl \
  --header "X-Vault-Token: VAULT_LOGIN_TOKEN_HERE" \
  http://127.0.0.1:8200/v1/sys/license
```
