# Basic Usage
1. Verify that the [requirements](/docs/api-gateway/consul-api-gateway-install#requirments) have been met.
1. Verify that the Consul API Gateway CRDs and controller have been installed and applied (see [Installation](/docs/api-gateway/consul-api-gateway-install)).
1. Configure the artifacts described below in [Configuration](/docs/api-gateway/configuration).
<CodeBlockConfig hideClipboard filename="values.yaml">
```yaml
apiGateway:
managedGatewayClass:
enabled: true
```
</CodeBlockConfig>
1. Issue the `kubectl apply` command to implement the configurations, e.g.:
```shell-session
$ kubectl apply -f gateway.yaml routes.yaml
```

### Using the Consul API Gateway Binary
You can download the Consul API Gateway binary and use it to manually start the control plane server.
1. Download the binary from the [Consul API Gateway repository](https://github.com/hashicorp/consul-api-gateway).
1. Navigate to the `consul-api-gateway-main` directory and build the binary:
```shell-session
$ go build
```
1. (Optional) Copy the binary to the execution path, e.g.:
```shell-session
$ cp consul-api-gateway /usr/bin
```
1. Use the `server` command to interact with the Consul API Gateway binary:
```shell-session
$ ./consul-api-gateway server <options>
```
The following options are supported:
| Option | Description | Required | Default |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- | ----------------------------------------------------------------------- |
| `-ca-file` | String value that specifies the path to the CA for the Consul server. | Required | none |
| `-ca-secret` | String value that specifies the CA secret for the Consul server. | Required | none |
| `-ca-secret-namespace` | String value that specifies the CA secret namespace for the Consul server. | Required | none |
| `-k8-context` | String value that specifies the Kubernetes context to use when starting the Consul server. | Optional | current context |
| `-k8-namespace` | String value that specifies the Kubernetes namespace to use when starting the Consul server. | Optional | `default` |
| `-log-json` | Boolean value that enables or disables JSON format for the log output. | Required | `false` |
| `-log-level` | String value that specifies the logging level. The following values are supported: <br/>- `trace` (highest level of detail) <br/>- `debug` <br/>- `info` <br/>- `warn` <br/>- `error` | Optional | `info` |
| `-metrics-port` | Integer value that specifies the port number for collecting metrics. | Optional | none |
| `-pprof` | Integer value that specifies the Go pprof port number for collecting metrics. | Optional | none |
| `-sds-server-host` | String value that specifies the host server for the secret discovery service (SDS). | Optional | `consul-api-gateway-controller.default.`<br/>`svc.cluster.`<br/>`local` |
| `-sds-server-host` | Integer value that specifies the port number for the secret discovery service (SDS). | Optional | `9090` |
You can also issue the `version` command to print the Consul API Gateway version to the console:
```shell-session
$ ./consul-api-gateway version
consul-api-gateway 0.1.0
```

### Helm installation failed: "no matches for kind"
```
Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: [unable to recognize "": no matches for kind "GatewayClass" in version "gateway.networking.k8s.io/v1alpha2", unable to recognize "": no matches for kind "GatewayClassConfig" in version "api-gateway.consul.hashicorp.com/v1alpha1"]
```
**Conditions:**
When this error occurs during the process of installing Consul API Gateway, it is usually caused by not having the required CRD files installed in Kubernetes prior to installing Consul API Gateway.
**Impact:**
The installation process will typically fail after this error message is generated
**Recommended Action:**
Install the required CRDs by using the command in Step 1 of the [Consul API Gateway installation instructions](/docs/api-gateway/consul-api-gateway-install) and then retry installing Consul API Gateway.
