For large-scale gateways it is optionally possible to use a dedicated pilot in the gateway namespace.

### Additional test templates

A number of helm test setups are general-purpose and should be installable in any cluster, to confirm

  assertEquals("hello, world!", chat.messages());

  chat.loadMore();
  chat.loadMore();
  assertEquals(""
      + "hello, world!\n"
      + "sup, bra?\n"
      + "yo dog", chat.messages());

  // Optional: confirm that your app made the HTTP requests you were expecting.
  RecordedRequest request1 = server.takeRequest();
  assertEquals("/v1/chat/messages/", request1.getPath());
  assertNotNull(request1.getHeader("Authorization"));

  scheme: http
  static_configs:
  - targets: ['server1:9000','server2:9000','server3:9000','server4:9000']
```

##### Resource (optional)

Optionally you can also collect resource metrics.

```yaml
scrape_configs:
- job_name: minio-job
  metrics_path: /minio/v2/metrics/resource
  scheme: http
  static_configs:
  - targets: ['localhost:9000']
```

### 4. Update `scrape_configs` section in prometheus.yml

## Configuration Directory

    - **Citadel** - Responsible for certificate issuance and rotation.

    - **Galley** - Responsible for validating, ingesting, aggregating, transforming and distributing config within Istio.

- **Operator** - The component provides user friendly options to operate the Istio service mesh.

## Repositories

The Istio project is divided across a few GitHub repositories:

* Utilizes Gateway injection, simplifying upgrades, allowing gateways to run in any namespace, and avoiding repeating config for sidecars and gateways.
* Published to official Istio Helm repository.
* Single chart for all gateways (Ingress, Egress, East West).

#### General concerns

```

Default upgrade strategies are specified in the `values.yaml` file. Update these fields if you'd like to use a different strategy.

### Configuration

Refer the [Values file](./values.yaml) for all the possible config fields.

You can specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```bash
helm install --name my-release --set persistence.size=1Ti minio/minio
```

That is, `--set some.field=true` should be passed, not `--set defaults.some.field=true`.

### Examples

#### Configuring mesh configuration settings

Any [Mesh Config](https://istio.io/latest/docs/reference/config/istio.mesh.v1alpha1/) options can be configured like below:

```yaml
meshConfig:
  accessLogFile: /dev/stdout
```

#### Revisions

export MINIO_STORAGE_CLASS_RRS=EC:2
```

Storage class can also be set via `mc admin config` get/set commands to update the configuration. Refer [storage class](https://github.com/minio/minio/tree/master/docs/config#storage-class) for
more details.

#### Note

- If `STANDARD` storage class is set via environment variables or `mc admin config` get/set commands, and `x-amz-storage-class` is not present in request metadata, MinIO server will

## Develop and verify

After you make a change, you can run `mvn clean teamcity-configs:generate` to generate and verify the generated TeamCity configuration XMLs.

You also need to run `mvn clean verify` with Java 8 before committing changes.
