Centos 安装 Minikube

1、修改 主机名

hostnamectl set-hostname minikube
           

2、关闭 selinux 及防火墙

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
 
systemctl stop firewalld && systemctl disable firewalld
           

 3、禁用swap

# 临时
swapoff -a
 
# 永久，打开/etc/fstab注释掉swap那一行
sed -i 's/.*swap.*/#&/' /etc/fstab
           

4、修改网桥过滤及地址转发

cat <<EOF > /etc/sysctl.d/k8s.conf
vm.swappiness = 0
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
EOF
 
# 加载
modprobe br_netfilter
 
# 生效
sysctl -p /etc/sysctl.d/k8s.conf
           

5、修改Cgroup Driver

# 消除告警
cat <<EOF > /etc/docker/daemon.json
{
    "registry-mirrors": ["http://hub-mirror.c.163.com"],
    "exec-opts": ["native.cgroupdriver=systemd"]
}
EOF
 
# 重启生效
systemctl restart docker
           

 6、安装 kubectl

curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.7.2/bin/linux/amd64/kubectl
chmod +x kubectl && mv kubectl /usr/local/bin/
           

7、安装 minikube

curl -Lo minikube https://storage.googleapis.com/minikube/releases/v1.7.2/minikube-linux-amd64
chmod +x minikube && mv minikube /usr/local/bin/
           

8、安装 conntrack 模块 

yum install conntrack -y
           

 9、安装 k8s

minikube start \
--image-repository registry.aliyuncs.com/google_containers \
--kubernetes-version v1.17.2 \
--vm-driver=none
           

10、查看状态

[[email protected] ~]# minikube status
minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured
           

11、查看 pod

[[email protected] ~]# kubectl get pods --all-namespaces
