创建CoreDNS:
之前已经下载了kubernetes的软件包，coreDNS的文件也包括在里面，可以直接用，也可以网上下载.
[[email protected] ~]# cd /usr/local/src/kubernetes/cluster/addons/dns [[email protected]-master dns]# cp coredns.yaml.base coredns.yaml 将配置文件coredns.yaml中，修改如下两个地方为自己的domain和cluster ip地址. 1.kubernetes __PILLAR__DNS__DOMAIN__ 改为 kubernetes cluster.local. 2.clusterIP: __PILLAR__DNS__SERVER__ 改为： clusterIP: 10.1.0.2
开始创建coredns服务：
[[email protected] dns]# kubectl create -f coredns.yaml serviceaccount "coredns" created clusterrole.rbac.authorization.k8s.io "system:coredns" created clusterrolebinding.rbac.authorization.k8s.io "system:coredns" created configmap "coredns" created deployment.extensions "coredns" created service "coredns" created
查看服务状态：
[[email protected] dns]# kubectl get pod -n kube-system -o wide NAME READY STATUS RESTARTS AGE IP NODE coredns-77c989547b-dv6fl 1/1 Running 0 2m 10.2.58.182 10.20.9.222 coredns-77c989547b-nltj9 1/1 Running 0 2m 10.2.49.8 10.20.9.221 [[email protected]-master dns]# [[email protected]-master dns]# kubectl get svc --all-namespaces NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE default kubernetes ClusterIP 10.1.0.1 <none> 443/TCP 1d kube-system coredns ClusterIP 10.1.0.2 <none> 53/UDP,53/TCP 4m
coreDNS解析测试：
[[email protected] dns]# kubectl run -i --tty busybox --image=docker.io/busybox /bin/sh If you don't see a command prompt, try pressing enter. / # / # nslookup www.baidu.com Server: 10.1.0.2 Address 1: 10.1.0.2 coredns.kube-system.svc.cluster.local Name: www.baidu.com Address 1: 180.149.132.151 Address 2: 180.149.131.98
说明coredns解析正常.
创建Dashboard
1.下载dashborad文件地址，大神已经修改好了我们直接执行就可以：
[root@k8s-node-1 tmp]# git clone https://github.com/unixhot/salt-kubernetes.git
2.创建dashborad服务：
[[email protected] addons]# kubectl create -f dashboard/ [[email protected]-master addons]# kubectl cluster-info Kubernetes master is running at https://10.20.9.220:6443 CoreDNS is running at https://10.20.9.220:6443/api/v1/namespaces/kube-system/services/coredns:dns/proxy kubernetes-dashboard is running at https://10.20.9.220:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
3.dashborad对外映射端口：
[[email protected] tmp]# kubectl get svc -o wide --all-namespaces NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR default kubernetes ClusterIP 10.1.0.1 <none> 443/TCP 1d <none> kube-system coredns ClusterIP 10.1.0.2 <none> 53/UDP,53/TCP 21m k8s-app=coredns kube-system kubernetes-dashboard NodePort 10.1.116.172 <none> 443:22584/TCP 5m k8s-app=kubernetes-dashboard
4.访问是https://nodeip:22584 进行访问 如：https://10.20.9.221:22584/
5.我们选择令牌登录，然后在master端执行如下命令，生成认证token登录：
[[email protected] ~]# kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}') Name: admin-user-token-tk4f5 Namespace: kube-system Labels: <none> Annotations: kubernetes.io/service-account.name=admin-user kubernetes.io/service-account.uid=00d6697a-67a2-11e8-8d7e-00505685a7ab Type: kubernetes.io/service-account-token Data ==== namespace: 11 bytes token: eyJhbGciOiJSUzI1NiIsImtpZCI6IiJ9.eyJpc3MiOiJrdWJlcm5ldGVzL3NlcnZpY2VhY2NvdW50Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9uYW1lc3BhY2UiOiJrdWJlLXN5c3RlbSIsImt1YmVybmV0ZXMuaW8vc2VydmljZWFjY291bnQvc2VjcmV0Lm5hbWUiOiJhZG1pbi11c2VyLXRva2VuLXRrNGY1Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9zZXJ2aWNlLWFjY291bnQubmFtZSI6ImFkbWluLXVzZXIiLCJrdWJlcm5ldGVzLmlvL3NlcnZpY2VhY2NvdW50L3NlcnZpY2UtYWNjb3VudC51aWQiOiIwMGQ2Njk3YS02N2EyLTExZTgtOGQ3ZS0wMDUwNTY4NWE3YWIiLCJzdWIiOiJzeXN0ZW06c2VydmljZWFjY291bnQ6a3ViZS1zeXN0ZW06YWRtaW4tdXNlciJ9.sluGejekiRB8KUS2pDhWx_NQS3axDyoRJP4NFi1fMvjx_-aXoznjCjk9iZRszu2vuMXvasNavigY4LL5SfSfNUir4kMYOI9tZkVTGkdC-fsa7E_GfXoP-HI1VhXz2BQ9Gu0eFkWO67pQYU37Ze0ZuUwNsnCB2S0sEF6yoV6MPSWVjLhqy65YEqJrtWp_fo87pebQAlH63cRY4MvyN_mB6u9Ddcs_1CH2HZS4hbdjjtO_ppB2zGSsyRcjWdD1TPPeAZErz4-MIHfwMBEcXq9BBuNaX0HEu-5qy6-cTmwlex0RpXVeOxDWfBnGGvb092cFWlI8faleFtyjI1HTraJ9sQ ca.crt: 1359 bytes
6.登录后信息如下：
访问url我用的是火狐浏览器，别的浏览器因为证书问题一直访问不了，还有就是我当时这样访问https://10.20.9.220:6443/ 但是用用户名密码访问死活过不去，有时间了在研究下.
