docker/kubernetes国内源/镜像源解决方式

最近在使用kubeadm时，被各种连接不上搞到崩溃。费了很多力气，基本都解决了。这里统一整理了国内的一些镜像源，apt源，kubeadm源等，以便查阅。

国内镜像源

Azure China提供了目前用过的质量最好的镜像源。无论是速度还是覆盖范围。而且都支持匿名拉取，也就是不需要登录。这点特别友好。

这里，我开发了一个小的脚本azk8spull，这个脚本可以自动根据镜像名称进行解析，转换为azure的mirror镜像源域名。并进行拉取。拉取完成后会自动进行tag重命名为原本的镜像名。该脚本已经开源在 https://github.com/xuxinkun/littleTools#azk8spull 上。以下是样例。

[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支持的镜像转换如下列表。

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

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

debian apt源

debian的apt的国内源更换为163的源，可以显著加速。

mv /etc/apt/sources.list /etc/apt/sources.list.bak # 换下源 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直接使用阿里云的源即可。速度也比较快。
