最近在使用kubeadm時，被各類鏈接不上搞到崩潰。費了不少力氣，基本都解決了。這裏統一整理了國內的一些鏡像源，apt源，kubeadm源等，以便查閱。html

國內鏡像源

Azure China提供了目前用過的質量最好的鏡像源。不管是速度仍是覆蓋範圍。並且都支持匿名拉取，也就是不須要登陸。這點特別友好。node

這裏，我開發了一個小的腳本azk8spull，這個腳本能夠自動根據鏡像名稱進行解析，轉換爲azure的mirror鏡像源域名。並進行拉取。拉取完成後會自動進行tag重命名爲本來的鏡像名。該腳本已經開源在 https://github.com/xuxinkun/littleTools#azk8spull 上。如下是樣例。nginx

[root@node-64-216 ~]# azk8spull quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.24.1
## azk8spull try to pull image from mirror quay.azk8s.cn/kubernetes-ingress-controller/nginx-ingress-controller:0.24.1.
0.24.1: Pulling from kubernetes-ingress-controller/nginx-ingress-controller
Digest: sha256:76861d167e4e3db18f2672fd3435396aaa898ddf4d1128375d7c93b91c59f87f
Status: Image is up to date for quay.azk8s.cn/kubernetes-ingress-controller/nginx-ingress-controller:0.24.1
## azk8spull try to tag quay.azk8s.cn/kubernetes-ingress-controller/nginx-ingress-controller:0.24.1 to quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.24.1.
## azk8spull finish pulling.

[root@node-64-216 ~]# azk8spull k8s.gcr.io/pause-amd64:3.1
## azk8spull try to pull image from mirror gcr.azk8s.cn/google_containers/pause-amd64:3.1.
3.1: Pulling from google_containers/pause-amd64
Digest: sha256:59eec8837a4d942cc19a52b8c09ea75121acc38114a2c68b98983ce9356b8610
Status: Image is up to date for gcr.azk8s.cn/google_containers/pause-amd64:3.1
## azk8spull try to tag gcr.azk8s.cn/google_containers/pause-amd64:3.1 to k8s.gcr.io/pause-amd64:3.1.
## azk8spull finish pulling.

azk8s.cn支持的鏡像轉換以下列表。git

global	proxy in China	format	example
dockerhub (docker.io)	dockerhub.azk8s.cn	`dockerhub.azk8s.cn/<repo-name>/<image-name>:<version>`	`dockerhub.azk8s.cn/microsoft/azure-cli:2.0.61` `dockerhub.azk8s.cn/library/nginx:1.15`
gcr.io	gcr.azk8s.cn	`gcr.azk8s.cn/<repo-name>/<image-name>:<version>`	`gcr.azk8s.cn/google_containers/hyperkube-amd64:v1.13.5`
quay.io	quay.azk8s.cn	`quay.azk8s.cn/<repo-name>/<image-name>:<version>`	`quay.azk8s.cn/deis/go-dev:v1.10.0`

Note:
k8s.gcr.io would redirect to gcr.io/google-containers, following image urls are identical:github

k8s.gcr.io/pause-amd64:3.1
gcr.io/google_containers/pause-amd64:3.1

debian apt源

debian的apt的國內源更換爲163的源，能夠顯著加速。docker

mv /etc/apt/sources.list /etc/apt/sources.list.bak
# 換下源
echo "deb http://mirrors.163.com/debian/ stretch main non-free contrib
deb http://mirrors.163.com/debian/ stretch-updates main non-free contrib
deb http://mirrors.163.com/debian/ stretch-backports main non-free contrib
deb-src http://mirrors.163.com/debian/ stretch main non-free contrib
deb-src http://mirrors.163.com/debian/ stretch-updates main non-free contrib
deb-src http://mirrors.163.com/debian/ stretch-backports main non-free contrib
deb http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib
deb-src http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib" > /etc/apt/sources.list

kubeadm源

kubeadm直接使用阿里雲的源便可。速度也比較快。curl

# Debian/Ubuntu
apt-get update && apt-get install -y apt-transport-https
curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -
cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
EOF
apt-get update
apt-get install -y kubelet kubeadm kubectl

# CentOS/RHEL/Fedora
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
setenforce 0
yum install -y kubelet kubeadm kubectl
