Centos 安裝 Minikube

1、修改 主機名

hostnamectl set-hostname minikube
           

2、關閉 selinux 及防火牆

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

 3、禁用swap

# 臨時
swapoff -a
 
# 永久，打開/etc/fstab注釋掉swap那一行
sed -i 's/.*swap.*/#&/' /etc/fstab
           

4、修改網橋過濾及位址轉發

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
 
# 加載
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
 
# 重新開機生效
systemctl restart docker
           

 6、安裝 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、安裝 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、安裝 conntrack 子產品 

yum install conntrack -y
           

 9、安裝 k8s

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

10、檢視狀态

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

11、檢視 pod

[[email protected] ~]# kubectl get pods --all-namespaces
NAMESPACE     NAME                               READY   STATUS    RESTARTS   AGE
