Kubernetes安裝dashboard的步驟
這篇文章主要講解了“Kubernetes安裝dashboard的步驟”，文中的講解內(nèi)容簡單清晰，易于學(xué)習(xí)與理解，下面請大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“Kubernetes安裝dashboard的步驟”吧！
建網(wǎng)站原本是網(wǎng)站策劃師、網(wǎng)絡(luò)程序員、網(wǎng)頁設(shè)計師等，應(yīng)用各種網(wǎng)絡(luò)程序開發(fā)技術(shù)和網(wǎng)頁設(shè)計技術(shù)配合操作的協(xié)同工作。創(chuàng)新互聯(lián)專業(yè)提供網(wǎng)站設(shè)計、網(wǎng)站建設(shè),網(wǎng)頁設(shè)計,網(wǎng)站制作(企業(yè)站、自適應(yīng)網(wǎng)站建設(shè)、電商門戶網(wǎng)站)等服務(wù),從網(wǎng)站深度策劃、搜索引擎友好度優(yōu)化到用戶體驗的提升,我們力求做到極致!
1. 準(zhǔn)備工作
參看CentOS7配置Kubernetes（K8S）集群 這里使用k8s版本為1.5.2
2. 準(zhǔn)備yaml

4. 注意事項
4.1 kubelet
### # kubernetes kubelet (minion) config # The address for the info server to serve on (set to 0.0.0.0 or "" for all interfaces) KUBELET_ADDRESS="--address=0.0.0.0" # The port for the info server to serve on # KUBELET_PORT="--port=10250" # You may leave this blank to use the actual hostname KUBELET_HOSTNAME="--hostname-override=192.168.0.51" # location of the api-server KUBELET_API_SERVER="--api-servers=http://192.168.0.51:8080" # pod infrastructure container KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=docker.io/openshift/origin-pod:latest" # Add your own! KUBELET_ARGS=""
將這里的ip地址修改為0.0.0.0和192.168.0.51(master地址)，這里將pod-infra指向本地鏡像pod-infra-container-image=docker.io/openshift/origin-pod:latest，需要在master和slave端都配置一遍
4.2 apiserver
### # kubernetes system config # # The following values are used to configure the kube-apiserver # # The address on the local server to listen to. KUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0" # The port on the local server to listen on. # KUBE_API_PORT="--port=8080" # Port minions listen on # KUBELET_PORT="--kubelet-port=10250" # Comma separated list of nodes in the etcd cluster KUBE_ETCD_SERVERS="--etcd-servers=http://192.168.0.51:2379" # Address range to use for services KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16" # default admission control policies #KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota" KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ResourceQuota" # Add your own! KUBE_API_ARGS=""
這里去除賬號驗證
4.3 pod-infrastructure
安裝Pod時需要用到這個鏡像，提前準(zhǔn)備，不然會因為GW的原因下不到

下載一個鏡像
[root@k8s-master elk]# docker pull docker.io/openshift/origin-pod
同樣的原因，提前準(zhǔn)備dashboard的鏡像

這里我選擇第一個鏡像
docker pull docker.io/mritd/kubernetes-dashboard-amd64
鏡像準(zhǔn)備，在master和slave端都進(jìn)行準(zhǔn)備
5. 進(jìn)入界面
通過http://192.168.0.51:8080/ui進(jìn)入頁面，即主機(jī)ip和apiserver端口
