docker/kubernetes国内源/镜像源解决方式

xinkun的博客 2019-06-14

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。

    globalproxy in Chinaformatexample
    dockerhub (docker.io)dockerhub.azk8s.cndockerhub.azk8s.cn/<repo-name>/<image-name>:<version>
    		dockerhub.azk8s.cn/microsoft/azure-cli:2.0.61
     dockerhub.azk8s.cn/library/nginx:1.15
    gcr.iogcr.azk8s.cngcr.azk8s.cn/<repo-name>/<image-name>:<version>
    		gcr.azk8s.cn/google_containers/hyperkube-amd64:v1.13.5
    quay.ioquay.azk8s.cnquay.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:

      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。

        # 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
