使用 kind 安装 k8s 多节点集群

安装精简化集群kind

1. 准备操作

1.1 yum 源安装docker

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2
yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce docker-ce-cli -y

1.2 docker相关

docker配置

mkdir -p /etc/docker
# docker的数据目录，根据需要自行修改
mkdir -p /DATA/docker

cat > /etc/docker/daemon.json <<EOF
{
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2",
  "default-address-pools": [
    {
        "base": "10.101.13.0/16",
        "size": 24
    }
  ],
  "bip": "10.101.13.254/24",
  "storage-opts": [
    "overlay2.override_kernel_check=true"
  ],
  "insecure-registries": [
    "docker.nexus.com:10010"
  ],
  "registry-mirrors" : [
    "https://ot2k4d59.mirror.aliyuncs.com/"
  ],
  "data-root": "/DATA/docker"
}
EOF

启动docker，开机自启

systemctl start docker
systemctl enable docker

2. kubectl安装

cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
        http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF

https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-aarch64/

yum install -y  kubectl-1.27.1 --disableexcludes=kubernetes

# 最新版
yum install -y  kubectl --disableexcludes=kubernetes

3. kind

安装kind程序

curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.11.1/kind-linux-amd64
curl -Lo ./kind https://github.com/kubernetes-sigs/kind/releases/download/v0.12.0/kind-linux-arm64
chmod +x ./kind
mv ./kind /user/local/bin/kind

# 最新版本
curl -Lo ./kind "https://kind.sigs.k8s.io/dl/v0.17.0/kind-$(uname)-amd64"
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

kind初始化 yaml
