Kubespray 2.5.0版

如何解决问题？

在您的输出中，

“拨号tcp 74.125.205.128:443:i/o超时”

，这意味着您在连接到此IP时遇到网络问题。也许你是在一个没有互联网接入的私人网络中，或者在某个阻止谷歌服务的地方（比如中国）

由于kubespray是一个ansile项目，有两种方法可以解决此问题：

1。从其他镜像站点下载图像

例如

阿里云

（中国最大的云提供商）。Docker图片都在这里：

google_containers/k8s-dns-sidecar-amd64的图像url

：

您可以拖动图像并重新标记它，然后可以在本地使用它：

  docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/k8s-dns-sidecar-amd64:1.14.10
  docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/k8s-dns-sidecar-amd64:1.14.10 gcr.io/google_containers/k8s-dns-sidecar-amd64:1.14.10

但是有这么多的图像，你可能有很多k8s节点，这是一个伟大的工作
因此，我们将有另一种方法

2。利用ansible角色的优势

角色中定义的所有变量都可以过份

在

roles/download/defaults/main.yml

中找到谷歌云注册表的所有

image\u repo

：

grep "image_repo:" ./roles/download/defaults/main.yml | grep "gcr.io" 

然后将它们放入文件

vars.yaml

或其他名称中，将

gcr.io

替换为

registry.cn hangzhou.aliyuncs.com

：

mkdir -p inventory/mycluster/group_vars/k8s-cluster  

mv inventory/mycluster/group_vars/k8s-cluster.yml inventory/mycluster/group_vars/  

cat > inventory/mycluster/group_vars/k8s-cluster/vars.yml << EOF

ingress_nginx_default_backend_image_repo: "registry.cn-hangzhou.aliyuncs.com/google_containers/defaultbackend"
EOF

同样，如果无法从下载图像，则应更改的图像url，并将其添加到

vars.yaml

中，然后重新运行剧本：

istio_statsd_image_repo: registry.docker-cn.com/prom/statsd-exporter
install_socat_image_repo: registry.docker-cn.com/"xueshanf/install-socat"
weave_kube_image_repo: registry.docker-cn.com/"weaveworks/weave-kube"
weave_npc_image_repo: registry.docker-cn.com/"weaveworks/weave-npc"
contiv_image_repo: registry.docker-cn.com/"contiv/netplugin"
contiv_auth_proxy_image_repo: registry.docker-cn.com/"contiv/auth_proxy"
nginx_image_repo: registry.docker-cn.com/nginx
dnsmasq_image_repo: registry.docker-cn.com/"andyshinn/dnsmasq"
test_image_repo: registry.docker-cn.com/busybox
helm_image_repo: registry.docker-cn.com/"lachlanevenson/k8s-helm"
vault_image_repo: registry.docker-cn.com/"vault"
registry_image_repo: registry.docker-cn.com/"registry"

---

上述方法不是在网络阻塞区域加载图像的最佳方法。最好的方法是使用

docker registry

或

neuxs 3.x

设置一个VPS和代理，并使其代理

https://gcr.io

、

https://quay.io

和

https://registry-1.docker.io
