2019獨角獸企業重金招聘Python工程師標準>>>

1. 準備工作

參看CentOS7配置Kubernetes（K8S）集群 這里使用k8s版本為1.5.2

2. 準備yaml

3. 啟動

kubectl apply -f k8s-dashboard.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，提前準備，不然會因為GW的原因下不到

[root@k8s-master elk]# docker search pod-infrastructure INDEX NAME DESCRIPTION STARS OFFICIAL AUTOMATED docker.io docker.io/openshift/origin-pod The pod infrastructure image for OpenShift 3 8 docker.io docker.io/davinkevin/podcast-server Container around the Podcast-Server Applic... 5 docker.io docker.io/infrastructureascode/aws-cli Containerized AWS CLI on alpine to avoid r... 4 [OK] docker.io docker.io/newrelic/infrastructure Public image for New Relic Infrastructure. 4 docker.io docker.io/infrastructureascode/uwsgi uWSGI application server 2 [OK] docker.io docker.io/infrastructureascode/serf A tiny Docker image with HashiCorp Serf us... 1 [OK] docker.io docker.io/mosquitood/k8s-rhel7-pod-infrastructure 1 docker.io docker.io/podigg/podigg-lc-hobbit A HOBBIT dataset generator wrapper for PoDiGG 1 [OK] docker.io docker.io/stefanprodan/podinfo Kubernetes multi-arch pod info 1 docker.io docker.io/tianyebj/pod-infrastructure registry.access.redhat.com/rhel7/pod-infra... 1 docker.io docker.io/w564791/pod-infrastructure latest 1 docker.io docker.io/grapeupci/infrastructure 0 docker.io docker.io/infrastructureascode/hello-world A tiny "Hello World" web server with a hea... 0 [OK] docker.io docker.io/jqka/pod-infrastructure redhat pod 0 [OK] docker.io docker.io/ocpqe/hello-pod Copy form docker.io/deshuai/hello-pod:latest 0 docker.io docker.io/oudi/pod-infrastructure pod-infrastructure 0 [OK] docker.io docker.io/sebastianhutter/podcaster python script to download podcasts https:/... 0 [OK] docker.io docker.io/shadowalker911/pod-infrastructure 0 docker.io docker.io/statemood/pod-infrastructure Automated build from registry.access.redha... 0 [OK] docker.io docker.io/tfgco/podium Podium is a blazing-fast player ranking se... 0 docker.io docker.io/trancong/pod2consul register pod with consul 0 docker.io docker.io/tundradotcom/podyn dockerized Podyn 0 docker.io docker.io/vistalba/podget Podget Docker with rename included. 0 [OK] docker.io docker.io/xplenty/rhel7-pod-infrastructure registry.access.redhat.com/rhel7/pod-infra... 0 docker.io docker.io/zengshaoyong/pod-infrastructure pod-infrastructure 0 [OK]

下載一個鏡像

[root@k8s-master elk]# docker pull docker.io/openshift/origin-pod

同樣的原因，提前準備dashboard的鏡像

[root@k8s-master es]# docker search kubernetes-dashboard INDEX NAME DESCRIPTION STARS OFFICIAL AUTOMATED docker.io docker.io/mritd/kubernetes-dashboard-amd64 kubernetes image kubernetes-dashboard-amd64 23 [OK] docker.io docker.io/brainqi/kubernetes-dashboard-amd64 full from gcr.io/google_containers/kuberne... 6 docker.io docker.io/ist0ne/kubernetes-dashboard-amd64 https://gcr.io/google_containers/kubernete... 6 [OK] docker.io docker.io/k8scn/kubernetes-dashboard-amd64 kubernetes-dashboard-amd64 image 6 [OK] docker.io docker.io/kubernetesdashboarddev/kubernetes-dashboard-amd64 6 docker.io docker.io/siriuszg/kubernetes-dashboard-amd64 gcr.io/google_containers/kubernetes-dashbo... 6 [OK] docker.io docker.io/mirrorgooglecontainers/kubernetes-dashboard-amd64 4 docker.io docker.io/larry0208/kubernetes-dashboard-amd64-google full from gcr.io/google_containers/kuberne... 3 docker.io docker.io/4admin2root/kubernetes-dashboard-amd64 gcr.io/google_containers/kubernetes-dashbo... 1 [OK] docker.io docker.io/kubernetesonarm/dashboard 1 docker.io docker.io/lhcalibur/kubernetes-dashboard-amd64 kubernetes-dashboard-amd64 1 [OK] docker.io docker.io/zounengren/kubernetes-dashboard-amd64 kubernetes dashboard 1.8.0 for kubernetes ... 1 docker.io docker.io/cokabug/kubernetes-dashboard-amd64 kubernetes-dashboard-amd64 0 [OK] docker.io docker.io/gysan/kubernetes-dashboard-amd64 gcr.io/google-containers/kubernetes-dashbo... 0 [OK] docker.io docker.io/huanwei/kubernetes-dashboard-amd64 kubernetes-dashboard-amd64 0 [OK] docker.io docker.io/kubernetesdashboarddev/kubernetes-dashboard-arm 0 docker.io docker.io/kubernetesdashboarddev/kubernetes-dashboard-arm64 0 docker.io docker.io/kubernetesdashboarddev/kubernetes-dashboard-ppc64le 0 docker.io docker.io/kubernetesdashboarddev/kubernetes-dashboard-s390x 0 docker.io docker.io/linkmancheng/kubernetes-dashboard-amd64 kubernetes-dashboard-amd64 0 [OK] docker.io docker.io/lolop82/kubernetes-dashboard 0 docker.io docker.io/rainf/kubernetes-dashboard-amd64 kubernetes-dashboard-amd64:v1.5.1 0 [OK] docker.io docker.io/steady1211/kubernetes-dashboard-amd64 kubernetes-dashboard-amd64 v1.6.1 0 [OK] docker.io docker.io/tristan129/kubernetes-dashboard-amd64 mirror from gcr.io/google_containers/kuber... 0 docker.io docker.io/visenzek8s/kubernetes-dashboard-amd64 0

這里我選擇第一個鏡像

docker pull docker.io/mritd/kubernetes-dashboard-amd64

鏡像準備，在master和slave端都進行準備

5. 進入界面

通過http://192.168.0.51:8080/ui進入頁面，即主機ip和apiserver端口
