CENTOS7 Yum Installation Kubernetes 1.1

Prerequisite: CENTOS7 has been update

Yum Update-y

First, to create a Yum source Master,slave are

Kubernetes Release version Yum source

http://cbs.centos.org/repos/virt7-docker-common-release/x86_64/os/Packages/

VI Virt7-docker-common-release.repo

[virt7-docker-common-release]name=virt7-docker-common-releasebaseurl=http://cbs.centos.org/repos/ Virt7-docker-common-release/x86_64/os/gpgcheck=0

Second, Yum installation Services

Yum-y Install--enablerepo=virt7-docker-common-release kubernetes ETCD

Third, add the hostname to Master,slave/etc/hosts, if the hostname has DNS resolution, you do not need to add

echo "192.168.5.221 k8s_master192.168.5.222 k8s_slave1192.168.5.237 k8s_slave2" >>/etc/hosts

Iv. Modification of/etc/kubernetes/config (all nodes)

# Logging to stderr means we get it in the Systemd journalkube_logtostderr= '--logtostderr=true ' # Journal message level, 0 is debugkube_log_level= "--v=0" # should this cluster being allowed to run privileged Docker containerskube_allow_priv= "--allo W-privileged=false "# How the Controller-manager, scheduler, and proxy find the apiserverkube_master="--master=http:// 192.168.5.221:8080 "

Five, disable the firewall

Systemctl Disable iptables-services firewalldsystemctl stop iptables-services FIREWALLD

Vi. Configuring the Kubernetes service on the master node

Modify the configuration file/etc/etcd/etcd.conf, make sure ETCD listens to all addresses, modify the following:

Etcd_name=defaultetcd_data_dir= "/var/lib/etcd/default.etcd" etcd_listen_client_urls= "http://0.0.0.0:2379"

Modify the configuration file/etc/kubernetes/apiserver, as follows:

# # # Kubernetes System config## The following values is used to configure the kube-apiserver## the address on the local s Erver to listen. Kube_api_address= "--address=0.0.0.0" # The port on the local server to listen on. Kube_api_port= "--port=8080" # PORT Minions Listen onkubelet_port= "--kubelet-port=10250" # Comma separated list of nodes in The Etcd clusterkube_etcd_servers= "--etcd-servers=http://127.0.0.1:2379" # Address range to use for Serviceskube_ Service_addresses= "--SERVICE-CLUSTER-IP-RANGE=10.254.0.0/16" # Default Admission Control Policieskube_admission_ Control= "--admission-control=namespacelifecycle,namespaceexists,limitranger,resourcequota" # Add your own! Kube_api_args= ""

Modify configuration file/etc/kubernetes/controller-manager, define minions IP address

Kubelet_addresses= "--machines=192.168.5.222,192.168.5.223"

Start the service

For SERVICES in Etcd kube-apiserver Kube-controller-manager Kube-scheduler; Do systemctl restart $SERVICES systemctl enable $SERVICES systemctl status $SERVICES done

Note: Certificate authentication will be automatically added to 1.1, the program will automatically generate the certificate file, you need to check the directory of the main genus Group

[[Email protected]_master kubernetes]# pwd/var/run/kubernetes[[email protected]_master kubernetes]# ll-rw-r--r--1 Kube kube 15:16 apiserver.crt-rw-------1 kube kube 1679 Nov 15:16 Apiserver.key

Restart Service

For SERVICES in Etcd kube-apiserver Kube-controller-manager Kube-scheduler; Do systemctl restart $SERVICES systemctl status $SERVICES done

Minions node configuration

#单独安装docker 1.7

Yum install Docker-1.7.1* docker-selinux-1.7.1systemctl enable docker-storage-setup.servicesystemctl enable Docker.service

#yum Installing Kubernetes Flannel

Yum-y Install--enablerepo=virt7-docker-common-release kubernetes Flannel

#创建docker-pool

Docker-storage-setup

#为etcd服务配置flannel, modify the configuration file/etc/sysconfig/flanneld

Flannel_etcd= "http://192.168.5.221:2379"

#修改kubernetes配置文件, specify Master. /etc/kubernetes/config

# How the Controller-manager, scheduler, and proxy find the apiserverkube_master= "--master=http://192.168.5.221:8080"

#配置kubelet服务. /etc/kubernetes/kubelet

# 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 onkubelet_port= "--port=10250" # Your may leave this blank to use the actual hostname Kubelet_hostname= "--hostname-override=192.168.5.237" # Location of the api-serverkubelet_api_server= "--api-servers= http://192.168.5.221:8080 "

#启动服务

For SERVICES in Kube-proxy Kubelet Docker Flanneld; Do systemctl restart $SERVICES systemctl enable $SERVICES systemctl status $SERVICES done

If the error bridge IP (...) does not match existing bridge configuration, it is because Docker's bridge starts before the flannel causes a conflict

Remove Docker 0

IP link Set dev Docker0 downbrctl delbr Docker0

Vi/usr/lib/systemd/system/docker.service modified as follows:

[Unit] Description=docker Application Container enginedocumentation=http://docs.docker.comafter=flanneld.servicewants= Docker-storage-setup.servicerequires=flanneld.servicesystemctl Restart Docker

#验证

#在每个minions可以看到2块网卡: Docker0 and Flannel0, the IP address of these 2 NICs is different on different machine IP addresses. But the same as the machine's 2 NIC IP

IP A | Grep-e "Flannel|docker" |grep inet inet 172.17.58.0/16 scope Global flannel0 inet 172.17.58.1/24 scope Global Docker 0

#现在登陆master, confirm the status of the Minions
