将这里的ip地址修改为0.0.0.0和192.168.0.51(master地址)，这里将pod-infra指向本地镜像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 clusterKUBE_ETCD_SERVERS="--etcd-servers=http://192.168.0.51:2379"# Address range to use for servicesKUBE_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=""

这里去除账号验证

4.3 pod-infrastructure

安装Pod时需要用到这个镜像，提前准备，不然会因为GW的原因下不到

[root@k8s-master elk]# docker search pod-infrastructureINDEX NAME DESCRIPTION STARS OFFICIAL AUTOMATEDdocker.io docker.io/openshift/origin-pod The pod infrastructure image for OpenShift 3 8docker.io docker.io/davinkevin/podcast-server Container around the Podcast-Server Applic... 5docker.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. 4docker.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 1docker.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 1docker.io docker.io/tianyebj/pod-infrastructure registry.access.redhat.com/rhel7/pod-infra... 1docker.io docker.io/w564791/pod-infrastructure latest 1docker.io docker.io/grapeupci/infrastructure 0docker.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 0docker.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 0docker.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... 0docker.io docker.io/trancong/pod2consul register pod with consul 0docker.io docker.io/tundradotcom/podyn dockerized Podyn 0docker.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... 0docker.io docker.io/zengshaoyong/pod-infrastructure pod-infrastructure 0 [OK]

下载一个镜像

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

同样的原因，提前准备dashboard的镜像

这里我选择第一个镜像

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

镜像准备，在master和slave端都进行准备
