How to route traffic from pysical server's port to minikube cluster?

由 一世执手 提交于 2021-02-10 18:11:56
问题 I want to sent traffic from one port through kubernetes cluster (using minikube) to another physical port. I don't know how to route traffic from physical port to cluster and from cluster to the second physical port. I'm exposing cluster via ingress (and I tested service solution also), i have one service to send external tarffic to pod and another to sent traffic from first pod to second pod. But I really don't know how to send this traffic from port to cluster and how to sent from cluster

Docker images disappearing over time

问题 I loaded some docker images running docker load --input <file> I can then see these images when executing docker image ls After a while images start disappearing. Every few minutes there are less and less images listed. I did not run any of images yet. What could be the cause of this issue? EDIT: This issue arises with docker inside minikube VM. 回答1: Since you've mentioned that Docker daemon runs inside minikube VM, I assume that you might hit K8s Garbage collection mechanism, which keeps

How can I install / use tcpdump on minikube?

由 冷暖自知 提交于 2021-02-10 06:44:26
问题 I'm trying to investigate a network issue and would like to install tcpdump / tshark. What package manager does minikube use? How can I install tcpdump? 回答1: It is not an easy task. Minikube VM is based on Buildroot distribution. Usually minikube uses docker to build a buildroot image, but you can clone buildroot repo and configure it to include tcpdump package using specific targets (make iso-minikube, make iso-menuconfig). Then you need to build a minikube image and run minikube using that

如何管理越来越多的Operator？OLM给你答案

由 本小妞迷上赌 提交于 2021-02-09 20:27:45
作者 | 匡大虎、阚俊宝 导读： OLM(Operator Lifecycle Manager) 作为 Operator Framework 的一部分，可以帮助用户进行 Operator 的自动安装，升级及其生命周期的管理。同时 OLM 自身也是以 Operator 的形式进行安装部署，可以说它的工作方式是以 Operators 来管理 Operators，而它面向 Operator 提供了声明式 (declarative) 的自动化管理能力也完全符合 Kubernetes 交互的设计理念。本文我们将来了解一下 OLM 的基本架构和安装使用。 OLM 组件模型定义 OLM 的出现是为了帮助没有如大数据，云监控等领域知识的用户能够自助式地部署并管理像 etcd、大数据分析或监控服务等复杂的分布式应用。因此从它的设计目标来说，OLM 官方希望实现面向云原生应用提供以下几个方向上的通用管理能力，包括： 生命周期管理：管理 operator 自身以及监控资源模型的升级和生命周期； 服务发现：发现在集群中存在哪些 operator，这些 operators 管理了哪些资源模型以及又有哪些 operators 是可以被安装在集群中的； 打包能力：提供一种标准模式用于 operator 以及依赖组件的分发，安装和升级； 交互能力：在完成了上述能力的标准化后，还需要提供一种规范化的方式（如 CLI

Can't access minikube service using NodePort from host on Mac

问题 I'm trying to deploy a single web application to Minikube on my Mac, and then access it in the browser. I'm trying to use the simplest of setups, but it's not working, I just get a "connection refused" error and I can't figure out why. This is what I'm trying: $ minikube start --insecure-registry=docker.example.com:5000 😄 minikube v1.12.3 on Darwin 10.14.6 ✨ Using the docker driver based on existing profile 👍 Starting control plane node minikube in cluster minikube 🔄 Restarting existing

Run command on Minikube startup

由 你说的曾经没有我的故事 提交于 2021-02-08 08:23:32
问题 I'm using Minikube for working with Kubernetes on my local machine, and would like to run a command on the VM just after startup (preferably before the Pods start). I can run it manually with minikube ssh , but that's a bit of a pain to do after every restart, and is difficult to wrap in a script. Is there an easy way to do this? The command in my case is this, so that paths on the VM match paths on my host machine: sudo mount --bind /hosthome/<user> /home/<user> 回答1: Maybe flags which can

Running Kubernetes locally on M1 Mac

由 倖福魔咒の 提交于 2021-02-07 19:37:33
问题 I'm looking to see if it's currently possible to run Kubernetes locally on a 2020 M1 MacBook air. The environment I need is relatively simple, just for going through some tutorials. As an example, this operator-sdk guide https://sdk.operatorframework.io/docs/building-operators/golang/tutorial/. So far I've tried microk8s and minikube , as they're tools I've used before on other machines. For both of these, I've installed them using brew after opening the terminal app "with Rosetta 2" (i.e
