## IstioOperatorSpec API

The `IstioOperatorSpec` API is intended to replace the installation and K8s parts of Helm values.yaml.

### Features and components

The operator has a very similar structure to istio/installer: components are grouped into features.

		switch {
		case ignoreKeys[key], postPolicyIgnoreKeys[key], strings.HasPrefix(key, encrypt.SseGenericHeader):
			continue
		case strings.HasPrefix(key, "X-Amz-Ignore-"):
			ignoreKey := strings.Replace(key, "X-Amz-Ignore-", "", 1)
			ignoreKeys[ignoreKey] = true
			// if it have already
			delete(checkHeader, ignoreKey)
		default:
			checkHeader[key] = value
		}
	}
	// map to store the metadata

 * Observe the data just as it will be transmitted over the network.
 * Access to the `Connection` that carries the request.

### Rewriting Requests

Interceptors can add, remove, or replace request headers. They can also transform the body of those requests that have one. For example, you can use an application interceptor to add request body compression if you're connecting to a webserver known to support it.

```java

        }
        return packageName.replace('.', '/') + '/';
    }

    /**
     * クラス名をクラスファイルのパス名に変換して返します。
     *
     * @param className
     *            クラス名
     * @return クラスファイルのパス名
     */
    protected static String toClassFile(final String className) {
        assertArgumentNotNull("className", className);

        return className.replace('.', '/') + ".class";
    }

    /**

          }
        }
      }
    ```

### Customizing Trusted Certificates ([.kt][CustomTrustKotlin], [.java][CustomTrustJava])

The full code sample shows how to replace the host platform’s certificate authorities with your own set. As above, **do not use custom certificates without the blessing of your server’s TLS administrator!**

=== ":material-language-kotlin: Kotlin"
    ```kotlin

		default:
			return nil, ErrUnsignedHeaders
		}
	}
	return extractedSignedHeaders, ErrNone
}

// Trim leading and trailing spaces and replace sequential spaces with one space, following Trimall()
// in http://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html
func signV4TrimAll(input string) string {

		}
	}

	if globalIsDistErasure {
		logger.Info("Configured max API requests per node based on available memory: %d", apiRequestsMaxPerNode)
	}

	if cap(t.requestsPool) != apiRequestsMaxPerNode {
		// Only replace if needed.
		// Existing requests will use the previous limit,
		// but new requests will use the new limit.
		// There will be a short overlap window,
		// but this shouldn't last long.

   * previous value (if any) will continue to be returned by {@code get(key)} unless it is evicted.
   * If the new value is loaded successfully it will replace the previous value in the cache; if an
   * exception is thrown while refreshing the previous value will remain, <i>and the exception will
   * be logged (using {@link java.util.logging.Logger}) and swallowed</i>.
   *
