kandi X-RAY | kubeless Summary

kubeless is a Go library typically used in Serverless applications. kubeless has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

kubeless is a Kubernetes-native serverless framework that lets you deploy small bits of code without having to worry about the underlying infrastructure plumbing. It leverages Kubernetes resources to provide auto-scaling, API routing, monitoring, troubleshooting and more. Kubeless stands out as we use a Custom Resource Definition to be able to create functions as custom kubernetes resources. We then run an in-cluster controller that watches these custom resources and launches runtimes on-demand. The controller dynamically injects the functions code into the runtimes and make them available over HTTP or via a PubSub mechanism.

            Unable to Trigger Kubeless Function With Kubeless Kafka Trigger

            I'm attempting to trigger a Kubeless function (written as a Java method) and it doesn't seem to be working. I've tried everything I can think to try, but I've run out of ideas. Below is the Java method (it's basically an echo service, for now).

            Launching tests in containers on Kubernetes
            Asked 2020-May-21 at 10:19

            I'm building a test automation tool that needs to launch a set of tests, collect logs and results. My plan is to build container with necessary dependency for test framework and launch them in Kubernetes.

            Is there any application that abstracts complexity of managing the pod lifecycle and provides a simple API to achieve this use-case preferably through API? Basically my test scheduler need to deploy a container in kubernetes, launch a test and collect log files at the end.

            I already looked at Knative and kubeless - they seem to be complex and may over-complicate what I'm trying to do here.

            Try looking at https://microk8s.io/, it was built for those purposes.

            And you can talk to the API server via the rest API same as in every k8s cluster.

            So it turns out , the root cause was that Custom resources with finalizers can "deadlock". The CustomResource "functions.kubeless.io" had a

            Finalizers: customresourcecleanup.apiextensions.k8s.io

            and this is can leave it in a bad state when deleting.

            I followed the steps mentioned in this workaround and it now gets deleted. Hope this helps anyone else who runs into this.

            As the comment says, you're using a version of Kubernetes that's very old. Deployment wasn't available under apps/v1 until Kubernetes 1.9, and you appear to be using 1.8.

            If you want to solve this problem without upgrading your cluster, you'll need to replace the apiVersion value in all of your Deployment objects with one of the older paths:

            Cannot create clusterrolebinding on fresh GKE cluster
            Asked 2018-Apr-11 at 21:07

            I provisioned a managed GKE cluster (Kubernetes version 1.9.4-gke.1) with basic authentication disabled. When i try to create RBAC configuration (for running my ingress controller) I get a following error: Error from server (Forbidden): clusterrolebindings.rbac.authorization.k8s.io is forbidden: User "XXX@gmail.com" cannot create clusterrolebindings.rbac.authorization.k8s.io at the cluster scope: Required "container.clusterRoleBindings.create" permission.

            I found two related questions:

            1. GKE clusterrolebinding for cluster-admin fails with permission error
            2. User "xxx" cannot create clusterrolebindings.rbac.authorization.k8s.io at the cluster scope

            First one contains a solution when basic authentication is enabled for the cluster which is not my case. And second question does not have an answer.

            My user is not owner of the GCP project but it has editor role in the project. I found that this behavior was observed by others.

            Please, advise how can I add the missing permission or otherwise defined RBAC on the GKE cluster when the cluster has basic authentication disabled.

            To create that ClusterRoleBinding, the caller must have container.clusterRoleBindings.create permission through GCP IAM. Only the OWNER and Kubernetes Admin IAM Roles contain that permission (because it allows modification of access control on your GKE clusters).

            So, to allow person@company.com to run that command, they must be granted one of those roles. I'd recommend the Kubernetes Admin role.:
