docker 和 Kubernetes都启动了 用kubectl cluster-info 命令查看显示：
from server (InternalError): an error on the server ("") has prevented the request from succeeding (get nodes)

请问一下这个是什么原因导致的？

现象如图：

原来的
k8s.gcr.io/etcd:3.4.3-0=gotok8s/etcd:3.4.13-0
正确的
k8s.gcr.io/etcd:3.4.13-0=gotok8s/etcd:3.4.13-0

Docker **官方镜像加速 已经不可用 docker/docs#8793

可用下列镜像地址替代

• https://dockerhub.azk8s.cn
• https://mirror.ccs.tencentyun.com

ref:

• https://github.com/Azure/container-service-for-azure-china/blob/master/aks/README.md#22-container-registry-proxy
• http://mirror.azk8s.cn/help/docker-registry-proxy-cache.html

环境

macos 10.15

docker edge 1.16.5

解决办法

修改了镜像 registly-mirror后，再次执行./load_images.sh
然后勾选启用k8s,前两项，第三项不需要勾选。

apply，然后网速好等待3分钟即可。（本人没有开翻墙，千M电信宽带，查的网线）

一直卡住怎么办？

1. 检查你的wifi网速，推荐使用网线

2. 不要开ss加速了，用国内镜像源了，你还加速？

3. 你修改镜像源后，到底有没有再次执行./load_images.sh？

4. 如果你做到了上面这些，依然有问题，请你换个网络环境/换电脑/试试看

按照指南，mac下通过官方的docker客户端，部署 Kubernetes dashboard 出错

 ~> kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
secret "kubernetes-dashboard-certs" configured
serviceaccount "kubernetes-dashboard" configured
service "kubernetes-dashboard" configured
unable to decode "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": no kind "Role" is registered for version "rbac.authorization.k8s.io/v1"
unable to decode "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": no kind "RoleBinding" is registered for version "rbac.authorization.k8s.io/v1"
unable to decode "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": no kind "Deployment" is registered for version "apps/v1beta2"

这个是怎么解决的？

还有很奇怪的是，docker客户端里k8s的状态一直是running，在它的组件如apiserver等容器的日志里面没有看到异常，是不是缺乏什么东西？

找不到镜像

registry-mirrors已经改了，但还是出现了上面的错误。而且我把images里的tag信息也都去掉了，也还是如此。

已自己解决

步骤如下：
替换vim images

k8s.gcr.io/kube-proxy:v1.19.3=gotok8s/kube-proxy:v1.19.3
k8s.gcr.io/kube-controller-manager:v1.19.3=gotok8s/kube-controller-manager:v1.19.3
k8s.gcr.io/kube-scheduler:v1.19.3=gotok8s/kube-scheduler:v1.19.3
k8s.gcr.io/kube-apiserver:v1.19.3=gotok8s/kube-apiserver:v1.19.3
k8s.gcr.io/coredns:1.7.0=gotok8s/coredns:1.7.0
k8s.gcr.io/pause:3.2=gotok8s/pause:3.2
k8s.gcr.io/etcd:3.4.13-0=gotok8s/etcd:3.4.13-0

之后./load_images.sh

然后docker-desktop软件软件中 enable Kubernetes

过几分钟就ok了

求更新连接~

请问怎么修改service-node-port-range这个的值呢

+1 k8s is starting

执行 load_images.sh成功，无异常。

重启啥的都是starting，在线求助 🙏🙏🙏

不再依赖阿里的镜像同步源

只有这个2.1.4.0的版本能用 搞了好久 给别人提个醒。。。。

Error: could not find a ready tiller pod

原因是作者更新了 tiller到 2.14.1
helm init的时候，还是去找 2.14.0

Failed to pull image "gcr.io/kubernetes-helm/tiller:v2.14.0": rpc error: code = Unknown desc = Error response from daemon: Get https://gcr.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

需要手工修改 tiller-deploy 里面的 "image": "gcr.io/kubernetes-helm/tiller:v2.14.0" 成 "image": "gcr.io/kubernetes-helm/tiller:v2.14.1" 就可以使用了

上周自动升级后，就一直"Kubernetes is starting"。 应该都是最新版。
帮忙分析下啥原因？ 谢谢。

Mac OS Mojave 10.14.6
Version 2.1.2.0(38030)

感觉关键步骤完全没写明白。。。。

像我的机器上目前是最新的V2.2.0.3，对应的k8s版本显示的是v1.15.5。
我修改了load_images.sh为1.15.5， 但是执行后发现k8s依然一直是starting中，应该还是镜像不对应导致的。

如果能查到当前版本的k8s需要的镜像是哪个版本的，或许这个问题就可以迎刃而解。
所以有什么方法吗？

当前只同步了最新的 edge 版本对应的kubernetes 依赖镜像，须增加stable版本的支持

dockerhub 的速度也变得感人，很多镜像加速也无法使用了

目前可用的镜像加速服务:

• 阿里云-镜像加速器

问题描述

https://registry.docker-cn.com已经无法访问

建议方案

将https://registry.docker-cn.com改为https://www.docker-cn.com

docker for mac engine:19.03.3 . 执行./load_images.sh k8s enable一直加载不了

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
Unable to connect to the server: x509: certificate is valid for docker-for-desktop, kubernetes, kubernetes.default, kubernetes.default.svc, kubernetes.default.svc.cluster.local, host.docker.internal, not kubernetes.docker.internal

./load_images.sh

这一步在哪里执行？点完哪一个按钮然后在哪里执行呢？

目前的正式release是k8s v1.15.5。这个没什么问题，但是etcd，coredns这些的版本怎么找
