标签: minikube

我是Kubernetes的新手.在Kubernetes文档的帮助下,我安装了minikube(v0.24.1)并kubectl在我的Windows机器上.VirtualBox(版本5.1.18)也安装在我的机器上.

在开始之前minikube,我已经执行set HTTP_PROXY=xx.xx.xx:8080并set NO_PROXY=localhost,127.0.0.0/8,192.0.0.0/8在Windows命令提示符下

minikube通过传递代理详细信息开始

C:\minikube>minikube start --memory 4096  --vm-driver=virtualbox --docker-env http_proxy=xx.xx.xx:8080  --docker-env https_proxy=xx.xx.xx:8080 --docker-env no_proxy=localhost,127.0.0.0/8,192.0.0.0/8 --cache-images=false

来自Kubectl的错误:

C:\minikube>kubectl version
Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.0", GitCommit:"925c127ec6b946659ad0fd596fa959be43f0cc05", GitTreeState:"clean", BuildDate:"2017-12-15T21:07:38Z", …

我试图使用VM和minikube设置一个本地集群,因为Id已经阅读它唯一可能用于本地目的,但id喜欢加入辅助机器,并且我正在搜索创建连接和散列的方法.

当使用--vm-driver=none选项1 启动Minikube实例时会遇到以下警告:

WARNING: IT IS RECOMMENDED NOT TO RUN THE NONE DRIVER ON PERSONAL WORKSTATIONS
    The 'none' driver will run an insecure kubernetes apiserver as root that may 
    leave the host vulnerable to CSRF attacks

为什么主人容易受到攻击？这样的攻击怎么会起作用？

我尝试使用我的本地 docker 映像创建一个 pod，如下所示。

1.首先我在终端中运行这个命令

eval $(minikube docker-env)

2.我创建了一个docker镜像如下

sudo docker image build -t my-first-image:3.0.0 .

3.我创建了如下所示的 pod.yml 并运行此命令

kubectl -f create pod.yml.

4.然后我尝试运行这个命令

kubectl get pods

但它显示以下错误

NAME                             READY   STATUS             RESTARTS   AGE
multiplication-b47499db9-phpb7   0/1     ImagePullBackOff   0          23h
my-first-pod                     0/1     ErrImagePull       0          7s

5.我得到pods日志

kubectl describe pod my-first-pod

When I command minikube status it shows but with a GitHub link says that update minikube. Can you tell me how can I do this in a simple way?

$ minikube status
??  There is a newer version of minikube available (v1.3.1).  Download it here:

To disable this notification, run the following:
minikube config set WantUpdateNotification false

我试图从 docker.io 中提取图像，但我收到此错误，最近我更改了我的 DNS 我不确定原因是......我执行minikube ssh并执行docker pull然后我收到此错误

Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io on 10.0.2.3:53: read udp 10.0.2.15:32905->10.0.2.3:53: i/o timeout

我是 Kubernetes 新手。我成功创建了一个包含 Angular 前端应用程序的 2 个副本的部署，但是当我使用服务公开它并尝试使用“minikube service service-name”访问该服务时，浏览器无法向我显示该应用程序。

这是我的 docker 文件

如何更改.minikube运行 minikube 时创建的整个文件夹的位置？（使用Hyper-V的Windows 10系统）

C:\Users\username\.minikube

我最近开始接触 kubernetes。我遇到过FailedScheduling <unknown> default-scheduler 0/1 nodes are available: 1 node(s) were unschedulable，但不确定发生了什么。

是否是因为我的节点上没有足够的资源用于新的 pod，我需要增加它？不过，它看起来并没有使用 100% 的内存或 CPU。

这是我的吊舱kubectl describe pods plex-kube-plex-986cc6d98-lwns7 --namespace plex

我是 Kubernetes 的绝对初学者，我是按照本教程开始的。我已经成功编写了 yaml 文件。然而，一旦我部署它，我就无法访问网络应用程序。
