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(jiǎn)單清晰，易于學(xué)習(xí)與理解，下面請(qǐng)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！

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

3. 啟動(dòng)

kubectl apply -f k8s-dashboard.yaml

4. 注意事項(xiàng)

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(hào)驗(yàn)證

4.3 pod-infrastructure

安裝Pod時(shí)需要用到這個(gè)鏡像，提前準(zhǔn)備，不然會(huì)因?yàn)镚W的原因下不到

下載一個(gè)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(gè)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

感謝各位的閱讀，以上就是“Kubernetes安裝dashboard的步驟”的內(nèi)容了，經(jīng)過本文的學(xué)習(xí)后，相信大家對(duì)Kubernetes安裝dashboard的步驟這一問題有了更深刻的體會(huì)，具體使用情況還需要大家實(shí)踐驗(yàn)證。這里是億速云，小編將為大家推送更多相關(guān)知識(shí)點(diǎn)的文章，歡迎關(guān)注！
