Red Hat Integration Documentation Team


Describes the Red Hat Integration platform and provides the latest details on what's new in this release.

Chapter 1. Red Hat Integration

Red Hat Integration is a comprehensive set of integration and event processing technologies for creating, extending, and deploying container-based integration services across hybrid and multicloud environments. Red Hat Integration provides an agile, distributed, and API-centric solution that organizations can use to connect and share data between applications and systems required in a digital world.

Red Hat Integration includes the following capabilities:

  • Real-time messaging
  • Cross-datacenter message streaming
  • API connectivity
  • Application connectors
  • Enterprise integration patterns
  • API management
  • Data transformation
  • Service composition and orchestration

Chapter 2. Camel Extensions for Quarkus release notes

2.1. Camel Extensions for Quarkus features

Fast startup and low RSS memory
Using the optimized build-time and ahead-of-time (AOT) compilation features of Quarkus, your Camel application can be pre-configured at build time resulting in fast startup times.
Application generator
Use the Quarkus application generator to bootstrap your application and discover its extension ecosystem.
Highly configurable

All of the important aspects of a Camel Extensions for Quarkus application can be set up programatically with CDI (Contexts and Dependency Injection) or via configuration properties. By default, a CamelContext is configured and automatically started for you.

Check out the Configuring your Quarkus applications guide for more information on the different ways to bootstrap and configure an application.

Integrates with existing Quarkus extensions
Camel Extensions for Quarkus provides extensions for libraries and frameworks that are used by some Camel components which inherit native support and configuration options.

2.2. Supported platforms, configurations, databases, and extensions

  • For information about supported platforms, configurations, and databases in Camel Extensions for Quarkus version 2.2, see the Supported Configuration page on the Customer Portal (login required).
  • For a list of Red Hat Camel Extensions for Quarkus extensions and the Red Hat support level for each extension, see the Extensions Overview chapter of the Camel Extensions for Quarkus Reference (login required).

2.3. Technology preview extensions

Red Hat does not provide support for Technology Preview components provided with this release of Camel Extensions for Quarkus. Items designated as Technology Preview in the Extensions Overview chapter of the Camel Extensions for Quarkus Reference have limited supportability, as defined by the Technology Preview Features Support Scope.

2.4. Known issues

CAMEL-17158 AWS2 SQS When sending messages to a queue that has delay, the delay is not respected

If you create a queue with a delay, the messages sent using the camel-aws2-sqs component as a producer do not respect the delay that has been set for the queue.

The reason for this behavior is that Camel sets '0s' as the default delay when sending messages that override the queue settings.

As a workaround, you should set the same delay settings when using the Camel producer. For example, if you create a queue with a 5s delay, you should also set a 5s delay when using the camel-aws2-sqs producer.

ENTESB-17763 Missing productised transitive deps of camel-quarkus-jira extensions
Applications using the camel-quarkus-jira extension require an additional Maven repository to be configured either in the Maven settings.xml file or in the pom.xml file of the application project.

2.5. Important notes

Documentation availability
The documentation set for Red Hat build of Quarkus version 2.2 currently does not contain the full set of guides that we provide with releases of Red Hat build of Quarkus, so this documentation set for Camel Extensions for Quarkus contains links to the Red Hat build of Quarkus 1.11 documentation instead.

2.6. Additional resources

Chapter 3. Red Hat Integration Operators

Red Hat Integration provides Operators to automate the deployment of Red Hat Integration components on OpenShift. You can use the Red Hat Integration Operator to manage multiple component Operators. Alternatively, you can manage each component Operator individually. This section introduces Operators and provides links to detailed information on how to use Operators to deploy Red Hat Integration components.

3.1. What Operators are

Operators are a method of packaging, deploying, and managing a Kubernetes application. They take human operational knowledge and encode it into software that is more easily shared with consumers to automate common or complex tasks.

In OpenShift Container Platform 4.x, the Operator Lifecycle Manager (OLM) helps users install, update, and generally manage the life cycle of all Operators and their associated services running across their clusters. It is part of the Operator Framework, an open source toolkit designed to manage Kubernetes native applications (Operators) in an effective, automated, and scalable way.

The OLM runs by default in OpenShift Container Platform 4.x, which aids cluster administrators in installing, upgrading, and granting access to Operators running on their cluster. The OpenShift Container Platform web console provides management screens for cluster administrators to install Operators, as well as grant specific projects access to use the catalog of Operators available on the cluster.

OperatorHub is the graphical interface that OpenShift cluster administrators use to discover, install, and upgrade Operators. With one click, these Operators can be pulled from OperatorHub, installed on the cluster, and managed by the OLM, ready for engineering teams to self-service manage the software in development, test, and production environments.

3.2. Red Hat Integration Operator

You can use Red Hat Integration Operator 1.1 to install and upgrade multiple Red Hat Integration component Operators:

  • 3scale
  • 3scale APIcast
  • AMQ Broker
  • AMQ Interconnect
  • AMQ Streams
  • API Designer
  • Camel K
  • Fuse Console
  • Fuse Online
  • Service Registry

3.2.1. Supported components

Before installing the Operators using Red Hat Integration Operator 1.1, check the updates in the Release Notes of the components. The Release Notes for the supported version describe any additional upgrade requirements.

AMQ Streams new API version

Red Hat Integration Operator installs AMQ Streams 1.7.

AMQ Streams 1.7 introduces the v1beta2 API version, which updates the schemas of the AMQ Streams custom resources. Older API versions are now deprecated. After you have upgraded to AMQ Streams 1.7, you must upgrade your custom resources to use API version v1beta2.

For more information, see Introducing the v1beta2 API version.

Service Registry 2.0 migration

Red Hat Integration Operator installs Red Hat Integration - Service Registry 2.0.

Service Registry 2.0 does not replace Service Registry 1.x installations, which need to be manually uninstalled.

For information on migrating from Service Registry version 1.x to 2.0, see the Service Registry 2.0 release notes.

3.2.2. Support life cycle

To remain in a supported configuration, you must deploy the latest Red Hat Integration Operator version. Each Red Hat Integration Operator release version is only supported for 3 months.

3.2.3. Fixed issues

The following table lists the fixed issues that were affecting Red Hat Integration Operator 1.1. The issues related to OpenShift Container Platform 4.7 and were fixed in the OpenShift Container Platform 4.7.24 bug fix update.
