Infinispan Operator 0.3.0 expands container and security configuration!

Infinispan Operator 0.3.0 is now available with expanded configuration and security options:

Container Configuration

With this release of the Infinispan Operator, you can configure explicit CPU and memory limits for individual containers. The defaults are 0.5 CPUs and 512Mi of memory.

The Operator also lets you pass extra JVM options, which is useful for tracking native memory consumption or extra GC logging parameters.

Security Configuration

Starting with 0.3.0, credentials are automatically generated for data connector and management users when you instantiate the Infinispan Operator.

The default usernames are developer and admin for the data connector user and management user, respectively.

Generated passwords are stored in Kubernetes Secret instances. You can extract the passwords as follows:

For convenience, the default usernames are also stored in the secret. Using the jq command line tool, you can inspect both the username and password values with a single command:

If you want to set custom credentials for the data connector and management users, create Kubernetes Secret instances as follows:

When using a Credentials type authentication, the referenced secrets must contain username and password fields.

Trying It Out!

The easiest way to get started with the Infinispan Operator is via the simple tutorial. The Operator is compatible with vanilla Kubernetes environments, such as Minikube, as well as Red Hat OpenShift.

Available via Operator Hub

Install the Infinispan Operator directly from the Operator Hub, which is available out of the box on all OpenShift 4 versions. If you’re using a vanilla Kubernertes environment, you might need to install the Operator Lifecycle Manager before you can install via the Operator Hub.

The Infinispan Operator is also included in the community for Kubernetes Operators is available from operatorhub.io.

What’s Next?

The Operator configuration does not yet provide all capabilities available for Infinispan servers. We’re working through a process of configuration specification that distills the server configuration into a simple, easy to use, set of configuration options. The current proposal is being discussed openly here.

Infinispan 10 brings a brand new server that’s no longer based on WildFly. The Operator 0.x series will remain focused on Infinispan 9.x server, with Operator 1.x series focusing on Infinispan 10 and onwards.

Cheers, Galder

Infinispan on tour, March-April 2019

* *

Infinispan has been on tour!!

 I - Katia Aresti - had the chance to present 3 talks in 3 different conferences and countries during the last month:

Breizh Camp 2019 the 22th March, Rennes (France)

BreizhCamp - 9ème édition - 20

Greach Conf 2019, 29th March, Madrid (Spain)

Greach 2019

Voxxed Days Milano 2019, 13th April, Milan (Italy)

VoxxedDays Milan

Breizh Camp

2019 has been BreizhCamp’s 9th - Code Busters - edition and they sold-out the conference in a matter of hours (wow).

I did not have the time to attend any talk. Unfortunately, due to my personal schedule, I arrived on Thursday night, and I was presenting on Friday after lunch. This was the second time I was giving this presentation, but I did lot’s of changes since the first time, including:

On Friday morning I was stressed and I ran my presentation at the hotel. I arrived at the venue, delivered my talk and headed back to Paris. I deeply regretted not spending more time hanging out with other speakers and attendees, but I really couldn’t make it this time :(

Greach Conf

Greach Conf is a lovely conference held in Madrid (Spain) for several years now. A 100% international conference, it has been organized by the Groovy community. 

This year they have changed the conference lineup adding an Android/Testing track and focusing on a bigger spectrum of technologies around the JVM.

I learned a bunch of new things, including content related to SDKMan!, Gradle, the future of Grails and of course, Micronaut. As the principal maintainer of Spring-Boot and Infinispan integration, Micronaut felt new and familiar at the same time. I really enjoyed the workshop delivered by Alvaro Sánchez who will be in Devoxx France this week. The framework is really impressive. Give it a try!

You will find on Twitter a complete thread about my Greach Conf impressions:

Coming back to Paris after 3 amazing days in Madrid as speaker and attendee at @greachconf #greach opening a thread 👇🏻

Thanks to Breizh Camp, Greach Conf and Voxxed Days Milano for the opportunity to share around distributed caches and for the amazing time I’ve had during this month in each of the conferences.

This tour is now over for a while but will continue before summer. I will be presenting this talk (with upgrades, so stay tuned) in Dev Fest Lille in June 2019 (France), in Comunidad CODE (Virtual talk) and Software Crafters Bilbao in Spanish.

Devoxx France 

Devoxx France is taking place this week in Paris. I will be there, so if you want to chat about Distributed caches, Datagrids, NoSQL Key-Value databases, or integration with your favorite framework feel free to reach me on twitter!

There are lot’s of new features and Reactive APIs to be done for Infinispan 10, so my main focus will be there for a bit.

Stay Tuned And Happy Coding!

Operator 0.2.1 out with DNS ping and expanded customizations

We’ve just completed the release of the Infinispan Operator version 0.2.1. In this second minor release, we’ve added the following features:

DNS Cluster Discovery

Cluster nodes now discover each other using DNS ping, which uses name lookups. Each node publishes a headless service which they use to locate each other. Previously, Kubernetes APIs were queried to discover other nodes, but this required administrator rights. DNS ping does not require admin permissions.

Configurable Image

The Infinispan server image used by the operator is now configurable, e.g.

Configurable XML

You can now provide their own custom Infinispan server XML referencing an existing ConfigMap:

Note that this example requires a ConfigMap with the XML file to be created before hand.

Next Steps

We’re already working on version 0.3.0, and in parallel we’ve been working on our first OperatorHub submission. We hope to have some news for you very soon :)

Cheers, Galder

Infinispan Spring Boot Starter 2.1.5.Final and 1.0.7.Final are out!

Dear Infinispan and Spring Boot users,

We have just released Infinispan Spring Boot Starter 2.1.5.Final and 1.0.7.Final.

2.1.5.Final

* * 2.1.5.Final is using Infinispan 9.4.11.Final and Spring-Boot 2.1.4.RELEASE.

Important Spring-Boot bug fix

Previous versions of Spring-Boot 2.1.x contained a bug related to the multi-release jars. Infinispan contains multi-release jars, in consequence, we could not run our applications using java -jar with Java 11 (Java 8 worked fine). For additional explanations, read here. Spring-Boot team has fixed this bug and released the correction in Spring-Boot 2.1.4.RELEASE, along with many other features and bug fixes, so consider upgrading soon.

Statistics on Client/Server mode and Actuator

Statistics configuration in client/server mode for the client evolved in the latest Infinispan versions. As a remainder, to activate actuator statistics in client/server mode : "Configure 'infinispan.remote.statistics=true' in the", application.properties or - Configure ''infinispan.client.hotrod.statistics=true" in the hotrod-client.properties or - Configure by code, for example:

@Bean public InfinispanRemoteConfigurer infinispanRemoteConfigurer() \{     return () → new ConfigurationBuilder().statistics().enable().build(); }

===== JMX

If you want to use Infinispan and JMX, for example on Client/Server mode, set the 'jmx' property 'true' as explained above with the 'statistics' property. However, you might get a javax.management.InstanceAlreadyExistsException because both Infinispan and Spring will try to register the MXBean.

The correction will land on the next starter release. If you need to avoid this error today, you can tell Spring-Boot not to register the bean with the following code (Thanks Stéphane Nicoll for the tip!):

Testcontainers

This version includes an integration test using Testcontainers, JUnit5 and the Infinispan Server. Grab a look here if you are curious.

1.0.7.Final

* * 1.0.7.Final upgrades to 1.5.19.RELEASE and Infinispan 9.4.11.Final.

⭐ Don’t forget to star the project in GitHub if you like the starter! ⭐

You can find these releases in the maven central repository.

Please report any issues in our issue tracker and join the conversation in our Zulip Chat to shape up our next release.

Enjoy,

The Infinispan Team

Subatomic Infinispan Client

Today, the Quarkus project was released as a public beta. https://quarkus.io/ For those of you not familiar, Quarkus allows you to write your enterprise apps as you have done in the past with Hibernate/JAX-RS, but also to compile these applications to a Graal-VM native image. Running in a native image allows for the application to be started up in mere milliseconds, depending upon the app, all while using much less memory.

The Infinispan team is proud to announce that you can use the HotRod Java client in Quarkus and supports being compiled to a native image as well. This can allow you to startup and connect to a remote Infinispan server faster than ever before.

If you want a quick and simple example of how you can get this working you can take a look at the quick start which can be found at https://github.com/quarkusio/quarkus-quickstarts/tree/master/infinispan-client. This example covers configuring the client connection, cache injection and simple get/put operations as a basis.

The Infinispan Client Quarkus extension in addition to providing an easy way to create a Graal-VM native image with Infinispan Client also provides the following features to help the user get stuff done quicker.

Automatically Inject Important Resources

  1. RemoteCache (named)

  2. RemoteCacheManger

  3. CounterManager

User based ProtoStream Marshalling

Querying (Indexed / Non Indexed)

Continuous Query

Near Cache

Authentication/Authorization

Encryption

Counters

More details for these features as well as how to configure them can be found at https://quarkus.io/guides/infinispan-client-guide

Please let us know of any questions, concerns or suggestions at the usual places: forum or chat. We expect to continue enhancing this extension and would love to have any feedback.
