It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

If you need a 2 minute refresher of how to use Python types (even if you don't use FastAPI), check the short tutorial: [Python Types](python-types.md){.internal-link target=_blank}.

You write standard Python with types:

```Python
from datetime import date

from pydantic import BaseModel

  }

  private fun verifyClientState() {
    check(null !in (interceptors as List<Interceptor?>)) {
      "Null interceptor: $interceptors"
    }
    check(null !in (networkInterceptors as List<Interceptor?>)) {
      "Null network interceptor: $networkInterceptors"
    }

    if (connectionSpecs.none { it.isTls }) {
      check(sslSocketFactoryOrNull == null)
      check(certificateChainCleaner == null)

  @Throws(IOException::class)
  private fun start(socketAddress: InetSocketAddress) {
    check(!closed) { "close() already called" }

    val alreadyStartedAddress = socketAddress_
    if (alreadyStartedAddress != null) {
      check(socketAddress.address == alreadyStartedAddress.address) {
        "unexpected address"
      }
      check(socketAddress.port == 0 || socketAddress.port == alreadyStartedAddress.port) {

}

// checkObjectNameForLengthAndSlash -check for the validity of object name length and prefis as slash
func checkObjectNameForLengthAndSlash(bucket, object string) error {
	// Check for the length of object name
	if len(object) > 1024 {
		return ObjectNameTooLong{
			Bucket: bucket,
			Object: object,
		}
	}
	// Check for slash as prefix in object name
	if HasPrefix(object, SlashSeparator) {

            if (options.sessionId == null) {
                SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
                options.sessionId = sdf.format(new Date());
            }

            // Check that sessionId was generated
            assertNotNull(options.sessionId);
            assertTrue(options.sessionId.matches("\\d{14}"));
        } catch (Exception e) {

 *
 * @since 4.0.0
 */
@Experimental
public interface UpgradeOptions extends Options {
    /**
     * Returns the list of upgrade goals to be executed.
     * These goals can include operations like "check", "dependencies", "plugins", etc.
     *
     * @return an {@link Optional} containing the list of goals, or empty if not specified
     */
    @Nonnull
    Optional<List<String>> goals();

    /**

below.

Then type

```sh
kubectl create secret generic tls-ssl-minio --from-file=path/to/private.key --from-file=path/to/public.crt
```

Cross check if the secret is created successfully using

```sh
kubectl get secrets
```

You should see a secret named `tls-ssl-minio`.

## 3. Update deployment yaml file

    private boolean initialized = false;

    @Override
    public boolean isAvailable() {
        try {
            // Check if DiSNI is available on the classpath
            Class.forName("com.ibm.disni.RdmaActiveEndpointGroup");

            // Additional checks could include:
            // - Verifying RDMA devices are available
            // - Testing basic RDMA operations

### Checking cluster health for maintenance

You may query the cluster probe endpoint to check if the node which received the request can be taken down for maintenance, if the server replies back '412 Precondition Failed' this means you will lose HA. '200 OK' means you are okay to proceed.
