• k8s-离线安装k8s


    1.开始

    目标

    coreos的igniton.json有很强的可配置性,通过安装时指定集群配置的ignition.json,

    安装完成后打开https://{{Master_IP}}:6443/ui直接访问k8s集群。

     

    背景

    coreos的官网有一篇裸机安装coreos并部署k8s的教程,CoreOS + Kubernetes Step By Step

    请确保已阅,下图是在ignition.json中配置的实际流程。

    服务

    说明

    HTTP Server

    提供aci镜像下载,以及其他文件下载

    TimeZone.Service

    将时区设置为上海

    Registry.Service

    在rkt容器中运行,docker镜像服务,供整个集群下载k8s镜像

    ETCD.Service

    在rkt容器中运行,集群发现服务

    Flannel.Service

    在rkt容器中运行,为docker容器设置网络

    Docker.Service

     

    Kubelet.Service

    在rkt容器中运行,K8S的基础服务kubelet

    kubelet-gac.Service

    为K8S基础服务预缓存镜像gcr.io/google_containers

    kubelet-ssl.Service

    为K8S制作证书

    kubelet-kubectl.Service

    为K8S的Master节点安装kubectl工具

    kubelet-addon.Service

    为K8S集群安装dns,dashboard,heapster等服务

    2.部署

    准备http服务器

    http://192.168.3.235/k8s

    文件

    说明

    ./registry-2.6.1.tgz

    registry-2.6.1.aci

    ./etcd-v3.2.0.tgz

    etcd-v3.2.0.aci

    ./flannel-v0.7.1.tgz

    flannel-v0.7.1.aci

    ./hyperkube-v1.7.3.tgz

    hyperkube-v1.7.3.aci

    ./registry-data-v1.7.3.tgz

    ./registry/data(pause,hyperkube,dns,dashboard,heapster)

    ./kubectl-v1.7.0.tgz

    kubectl-v1.7.0

    aci , rkt的标准镜像,coreos启动时把aci镜像下载到本地,这样不需要请求镜像服务即可运行服务;

    registry-data , 在互联网环境下预下载好安装k8s所需镜像,然后将registry/data导出,服务器下载后,待registry服务启动将能提供k8s镜像给集群内节点下载;

    kubectl , kubectl工具目前是1.7.0版本

     

    准备pem格式根证书

    生成ignition.json

    使用jinja2将上述模版转化为实际配置

    ./systech01.yml

    ./systech02.yml

    ./systech03.yml

     

    下载CT工具将yml转化为ignition.json

    # ct v0.4.2

    2017.09.23

    github : https://github.com/coreos/container-linux-config-transpiler

     

    安装coreos

    使用上面生成的ignition.json安装coreos,一切顺利访问https://192.168.3.102:6443/ui将会看到dashboard页面
