Gradle is also made up of several different processes that work together to "run the build", such as the Gradle daemon and the `gradlew` command.

Each process, or "runtime", applies different constraints to the code that runs in that process.
For example, each process has different supported JVMs and a different set of services available for dependency injection.

Build the Native Image
----------------------

Compile the classes and metadata into a Graalvm native image.

```
./gradlew --info native-image-tests:nativeImage
```

Execute
-------

The native image runs JUnit 5 tests in the project.

```
./native-image-tests/build/graal/ConsoleLauncher

The MinIO server runs a key-derivation algorithm to generate the KEK using a pseudo-random function ([PRF](#prf)):
`KEK := PRF(EK, IV, context_values)` where:

    - it also sets up a UDS socket for istio-cni to send logs to this container.
    - based on config, it may run the 'repair' controller that detects pods where istio setup fails and restarts them, or created in corner cases.
    - if ambient is enabled, also runs an ambient controller, watching Pod, Namespace

- `istio-cni`
    - CNI plugin executable copied to `/opt/cni/bin`

testRuntimeOnly("com.squareup.okhttp3:mockwebserver3-junit5:4.12.0")
```

Then in tests annotated `@org.junit.jupiter.api.Test`, you may add a [MockWebServer] as a test
method parameter. It will be shut down automatically after the test runs.

```
class MyTest {
  @Test
  void test(MockWebServer server) {
    ...
  }
}
```

Alternately you may add the [MockWebServer] as a constructor parameter:

```
class MyTest {

- When you create your backup job, choose the backup repository you created above.

## Test the setup

[requirements updater readme](https://github.com/tensorflow/tensorflow/blob/master/ci/official/requirements_updater/README.md)

### Prerequisites for Local Testing

To run tests locally, follow these steps:

1.  Navigate to the relevant directory:
    ```
    cd ci/official/wheel_test
    ```
2.  Run a script for creating requirements file:
    ```
    bash update_requirements.sh <path_to_tensorflow_wheel> <python_version>
    e.g.:

	retry:
	  attempts: 10 # number of retries for the job before giving up
	  delay: "500ms" # least amount of delay between each retry
```

You can create and run multiple 'replication' jobs at a time there are no predefined limits set.

## Batch Jobs Terminology

### Job

### 2. Configure authentication type for Prometheus metrics

MinIO supports two authentication modes for Prometheus either `jwt` or `public`, by default MinIO runs in `jwt` mode. To allow public access without authentication for prometheus metrics set environment as follows.

```
export MINIO_PROMETHEUS_AUTH_TYPE="public"
minio server ~/test
```

### 3. Configuring Prometheus

Follow these steps to run the Spark Pi example:

- Login as user **‘spark’**.
- When the job runs, the library can now use **MinIO** during intermediate processing.
- Navigate to a node with the Spark client and access the spark2-client directory:

```
cd /usr/hdp/current/spark2-client
su spark
```
