kubernetes的最佳实践

关于k8s是什么？再重复写没啥必要了，简单的讲，就是google把自己的运维系统给开源了。

# 其中proxy表示需要挂代理，你懂的
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
proxy=socks5h://127.0.0.1:1080   
EOF
# yum install -y kubectl
setenforce 0
yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes
systemctl enable kubelet && systemctl start kubelet


cat <<EOF >  /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sysctl --system

用kubeadm安装单master集群

{
  "bridge":"none",
  "registry-mirrors" : [
    "http://607743f3.m.daocloud.io"
  ]
}
