            How do I use Spring Cloud Kubernetes to programmatically write a ConfigMap value?
            Asked 2021-Nov-02 at 10:49

            I have a service that uses Spring Cloud Kubernetes Config to reload its configuration when a value in a ConfigMap changes. That all works great.

            Is it possible to use Spring Cloud Kubernetes (or one of its dependencies) to write a ConfigMap value? I didn't see any examples of this in the documentation (here). Can I do this programmatically, or do I need to call the underlying Kubernetes APIs to do this?

            On further analysis and going through the docs, disabling of these features must be set in bootstrap.yml - https://docs.spring.io/spring-cloud-kubernetes/docs/current/reference/html/index.html#kubernetes-ecosystem-awareness.

            Spring Cloud Kubernetes: Timeout waiting for informers cache to be ready

            However, I get an error message (Timeout waiting for informers cache to be ready, is the kubernetes service up?) during the initialization, as well as high verbosity, both of which I am unable to find information online to help me pinpoint the cause.

            You need to grant neccessary permissions to your spring app, with dependency spring-cloud-starter-kubernetes-fabric8-all that you're using, you will need to grant these permissions: "configmaps", "pods", "services", "endpoints", "secrets".

            The el filter must return a boolean value. The discovered service, which should be filtered, is injected as #root in the expression. So #root.metadata.name retrieves the actual name of the kubernetes service.

            This part of code of KubernetesDiscoveryClient does the filtering:

            ANSWER

            Answered 2020-Mar-28 at 14:49

            I did a some googling and little research. I foud following:

            1. The missing class com.azure.data.cosmos.internal.directconnectivity.rntbd.RntbdConstants$RntbdContextRequestHeader is a part of azure-cosmosdb-direct, pls see pom.xml, class is located here.
            2. azure-cosmosdb-direct is missing from your dependency list. I assume it's incomplete or hidden for some reason(?)
            3. Looking at exception stacktrace it's clear that at com.azure.data.cosmos.internal.directconnectivity.rntbd.RntbdContextRequest$Headers.(RntbdContextRequest.java:126) is a place where exceptiom occurs. So that means RntbdContextRequest class actually existsts (it's also is a part of azure-cosmosdb-direct). Therefore you have needed dependency, but it probably has wrong version.

            I propose you to look a bit deeper into how azure-cosmosdb-direct dependency is injected in your project and fix its version. Just try to declare it directly in your pom.xml with the latest version.

            Hope I helped you.
