RKE安装kubernetes集群

  • 1,将普通用户加入到Docker组

    sudo usermod -aG docker 用户名

  • 2,关闭防火墙

    sudo ufw disable

  • 3.0 安装openssh-server(如果已经安装,可省略)

    #centos
yum install openssh-server
#ubuntu
apt-get install openssh-server

  • 3,建立ssh单向通道

    ssh-keygen  #三次回车，生成ssh公钥和私钥文件
ssh-copy-id <节点用户名>@<节点IP>
例如: ssh-copy-id [email protected]

  • 4,验证ssh

    ssh 192.168.3.162
exit

  • 5,禁用selinux(CentOS7)

    vi /etc/sysconfig/selinux
设置SELINUX=disabled

  • 6,禁用swap

    vi /etc/fstab
swap那句话注释掉,重启

  • 1,从github rke的仓库中下载rke文件

    https://github.com/rancher/rke/releases/

  • 2,在rke同级文件夹下创建cluster.yml

    nodes:
- address: 节点IP(例如:1.2.3.4)
user: 节点用户名(例如:demo)
role: [controlplane,worker,etcd]
#network:
#  plugin: flannel
#  options:
#    flannel_iface: enp3s0

  • 3,授予执行权限

    chmod 777 rke

  • 4,执行安装

    ./rke up --config cluster.yml

  • rke

    已知的问题

  • 在单节点下(未测试多节点),k8s POD中的容器无法ping通dns,无法访问外部网络,不知道是何原因.
