            Kubernetes MirrorMaker2 Cannot Load Secret
            Asked 2022-Mar-19 at 20:27

            I have a weird issue that no one can pinpoint. To make sure it was not an Azure Kubernetes issue, I also spun up minikube to test locally and I am getting the same error. The one thing in common Strimzi 0.28 for MirrorMaker2.

            I moved it as I didn't want to spam as a gentleman by the name of scholzj helped and gave some great advice. But nothing seems to work.

            The issue was using cat <

            I think it's because of $ in the username. EH needs this as the actual username for the connection. Once I made the above into a file between cat < it ran from the CLI without changing anything.

            It worked.

            Assuming that the Prometheus pods did start, their collective hostnames would be found via service discovery like prometheus.monitoring.svc.cluster.local

            External access to Kafka using Strimzi
            Asked 2021-Oct-28 at 15:45

            I'm attempting to provide bi-direction external access to Kafka using Strimzi by following this guide: Red Hat Developer - Kafka in Kubernetes

            My YAML taken from the Strimizi examples on GitHub, is as follows:



            Answered 2021-Oct-28 at 15:45

            Strimzi just created the Kubernetes Service of type Loadbalancer. It is up to your Kubernetes cluster to provision the load balancer and set its external address which Strimzi can use. When the external address is listed as pending it means the load balancer is not (yet) created. In some public clouds that can take few minutes, so it might be just about waiting for it. But keep in mind that the load balancers are not supported in all environments => and when they are not supported, you cannot really use them. So you really need to double check whether your environment supports them or not. Typically, different clouds would support load balancers while some local or bare-metal environments might not (but it really depends).

            I'm also not really sure why did you configured the advertised host and port:



            Strimzi kafka exporter kafka_consumergroup_members metric
            Asked 2021-Jul-20 at 14:31

            I deployed a kafka cluster with consumer and producer clients on Kubernetes using Strimzi operator. I used the following strimzi deployment file ,

            I am using Kafka exporter to monitor consumer related metrics (Messages in/out per second per topic, lag by consumer group, offsets etc..). However, I am interested in configuring Prometheus to scrape the kafka_exporter metric "kafka_consumergroup_members" for later display on Grafana. What additional configuration shall I add to the strimzi Prometheus configuration file ( or any other deployment file (e.g., so that "kafka_consumergroup_members" from the kafka_exporter metric is scraped.



            Answered 2021-Jul-20 at 14:31

            The Kafka Exporter is a separate tool which provides additional metrics not provided by Kafka itself. It is not configurable in what metrics does it offer - you can only limit for which topics / consumer groups it will show the metrics.

            So all metrics supported by Kafka Exporter are published on its metrics endpoint and when Prometheus scapes them it should scrape all of them. So if you have the other KAfka Exporter metrics in your Prometheus, you should already have this one as well (you actuall need to have some active consumer grups for it to show up).



            JsonMappingException while loading yaml Kafka configuration via Fabric8io kubernetes-client

            But when i load yaml resources with kubernetes-client:5.2.1 library from Java code, there is an Exception occurs:



            Answered 2021-Mar-19 at 06:59

            I'm from Fabric8 team. Kafka is a Custom Resource which means it's model is not registered in KubernetesClient so this is the reason why you're facing No resource type found error from KubenetesClient. KubernetesClient provides two methods for dealing with Custom Resources:

            1. Typeless API - Usage of CustomResources as raw Hashmaps
            2. Typed API - Provide POJOs for CustomResource types

            I'll provide examples of using both APIs to load your Kafka yaml fragment.

            Typeless API:

            For Typeless API you would need to provide a CustomResourceDefinitionContext, an object with details of CustomResource group, version, kind, plural etc. Here is how it would look like:



            Helm Chart: How do I install dependencies first?
            Asked 2020-Feb-19 at 08:26

            I've been developing a prototype chart that depends on some custom resource definitions that are defined in one of the child charts.

            To be more specific, I'm trying to create the resources defined in the strimzi-kafka-operator within my helm chart and would like the dependency to be explicitly installed first. I followed the helm documentation and added the following to my Chart.yaml



            Answered 2020-Feb-19 at 08:26

            Regarding CRD's: the fact that Helm by default won't manage those1 is a feature, not a bug. It will still install them if not present; but it won't modify or delete existing CRD's. The previous version of Helm (v2) does, but (speaking from experience) that can get you into all sorts of trouble if you're not careful. Quoting from the link you referenced:

            There is not support at this time for upgrading or deleting CRDs using Helm. This was an explicit decision after much community discussion due to the danger for unintentional data loss. [...] One of the distinct disadvantages of the crd-install method used in Helm 2 was the inability to properly validate charts due to changing API availability (a CRD is actually adding another available API to your Kubernetes cluster). If a chart installed a CRD, helm no longer had a valid set of API versions to work against. [...] With the new crds method of CRD installation, we now ensure that Helm has completely valid information about the current state of the cluster.

            The idea here is that Helm should operate only at the level of release data (adding/removing deployments, storage, etc.); but with CRD's, you're actually modifying an extension to the Kubernetes API itself, potentially inadvertently breaking other releases that use the same definitions. Consider if you're on a team that has a "library" of CRDs shared between several charts, and you want to uninstall one — formerly, With v2, Helm would happily let you modify or even delete those at will, with no checks on if/how they were used in other releases. Changes to CRDs are changes to your control plane / core API, and should be treated as such — you're modifying global resources.

            In short: with v3, Helm positions itself more as a "developer" tool to define, template, and manage releases; CRDs, however, are meant to be managed independently e.g. by a "cluster administrator". At the end of the day, it's a win for all sides, since developers can setup/teardown deployments at will, with confidence that it's not going to break functionality elsewhere... and whoever's on call won't have to deal with alerts if/when you accidentally delete/modify a CRD and break things in production :)

            See also the extensive discussion here for more context behind this decision.

            Hope this helps!
