Re: strimzi operator running namespaced

Jakub Scholz
 

Strimzi requires access to some cluster wide resources for some important features such as rack awareness. It is also required for example for node-port access or disk resizing. You can disable some of them if you do not need them, but at minimum you would need to create the CRDs and the ClusterRoles. The ClusterRoleBindings might be possibly changed to RoleBindings if you are willing to sacrifice the features.

Thanks & Regards

Hi guys,

I am trying to intall Strimzi operator 0.29 but i am running on a multi tenant kubenetes cluster so I have limited permission. for example I can't create clusterroles/roles objects.

Is there a way that the operator could run on a namespaced level with less permission over the cluster?

 

thanks!

[ANNOUNCE] [RELEASE] Strimzi Canary 0.3.0 released

Paolo Patierno
 

We have released Strimzi Canary 0.3.0.
Strimzi canary is a tool which acts as an indicator of whether Kafka clusters are operating correctly. This is achieved by creating a canary topic and periodically producing and consuming events on the topic and getting metrics out of these exchanges.
For more details about what it does and how to use it, check the README.md file.

For more details and installation files, go to: https://github.com/strimzi/strimzi-canary/releases/tag/0.3.0

Thanks to everyone who contributed to this release!

Re: RC1 of Strimzi Canary 0.3.0

Paolo Patierno
 

Thanks for reporting this kwall!

I think that it's an important fix because without it re-auth feature is un-usable and the canary itself if it's enabled.
Before a 0.3.0-RC2 out, I would like to ping Sarama maintainers to see if there is space for approving your fix and releasing a new patched Sarama version 1.33.1.

Thanks,
Paolo

An issue has been discovered with in the Strimzi RC1 build.  The root cause is a defect in new KIP-368 implementation within the latest release of Sarama 1.33.0 include in the Strimzi RC.    The defect is described by https://github.com/Shopify/sarama/issues/2233 and leads to the canary unexpectedly disconnecting from the kafka cluster and may also lead to unexpected out of memory problems being suffered by the kube pod hosting the canary.

There is already a PR open against Sarama with a proposed fix.  It is hoped if the fix is accepted and a new Sarama micro release made soon, the Strimzi Canary RC will be respun soon.

[ANNOUNCE] [RELEASE] Strimzi Kafka Operators 0.29.0

Jakub Scholz
 

Strimzi Kafka Operators 0.29.0 has been released. The main changes in this release include:
* Support for new Apache Kafka releases (3.0.1, 3.1.1 and 3.2.0)
* Renew user certificates in User Operator only during maintenance windows
* New rebalancing modes in the `KafkaRebalance` custom resource to add or remove brokers
* Experimental KRaft mode (ZooKeeper-less Kafka)
* Experimental support for the s390x platform

For more details and installation files, go to https://github.com/strimzi/strimzi-kafka-operator/releases/tag/0.29.0

Important: This release supports only the API version v1beta2 and CRD version apiextensions.k8s.io/v1. If upgrading from Strimzi 0.22, migration to v1beta2 needs to be completed for all Strimzi CRDs and CRs before the upgrade to 0.28 is done! If upgrading from Strimzi version earlier than 0.22, you need to first install the CRDs from Strimzi 0.22 and complete the migration to v1beta2 for all Strimzi CRDs and CRs before the upgrade to 0.28 is done! For more details about the CRD upgrades, see the documentation.

Re: Attempting to install Strimzi/Kafka on my microk8s cluster

Jakub Scholz
 

The first node looks ok. But if you check the description, you can see that some of the nodes are marked with the taint:

That is what the events are complaining about. I expect that the taint is set there for some reason - but I never used Microk8s, so not sure where to look for more info. Also, the Conditions in the descriptions are unknown. So my guess is that maybe the cluster cannot communicate with them? Maybe some Microk8s forum might give you better answers on what might be causing this.

Thank you Jakub, appreciate your response!

I'm not exactly sure I understand how to check if each node is "reachable", but here is the output of "kubectl describe nodes", and I don't know if the fact that all three Pis are listed means that they are in-fact reachable.

Re: Attempting to install Strimzi/Kafka on my microk8s cluster

Re: Attempting to install Strimzi/Kafka on my microk8s cluster

Jakub Scholz
 

Hi Tim,

That looks like some scheduling issue between your cluster and your storage. TBH, these issues are a bit hard to decode without your environment. The taint suggests that some of your nodes are unreachable, so that might be the cause of the issue?

Thanks & Regards
Jakub
