1、制作本地yum源

# 下载所需工具依赖包

yum install --downloadonly --downloaddir=/opt/repo ntpdate wget httpd createrepo vim telnet netstat lrzsz chroot unzip git net-tools

# 配置国内yum源

yum clean all

yum makecache

yum install -y wget createrepo

wget -O /etc/yum.repos.d/docker-ce.repo

yum install --downloadonly --downloaddir=/opt/repo docker-ce

# 配置国内kubernetes源

cat > /etc/yum.repos.d/kubernetes.repo << EOF

[kubernetes]

name=Kubernetes

baseurl=

enabled=1

gpgcheck=0

repo_gpgcheck=0

gpgkey=

EOF

# 下载好kubelet-1.23.0 kubeadm-1.23.0 kubectl-1.23.0所需要的依赖包

yum install --downloadonly --downloaddir=/opt/repo kubelet-1.23.0 kubeadm-1.23.0 kubectl-1.23.0

wget --no-check-certificate

wget

# 将下载软件包的目录制作为yum源

createrepo /opt/repo/

createrepo --update /opt/repo

cd /opt/repo

yum install -y httpd

systemctl start httpd && systemctl enable httpd

ln -s /opt/repo /var/www/html/

cd ~

2、k8s集群节点配置yum源

cd /etc/yum.repos.d/

mkdir backup

mv CentOS-* backup/

# 在每个节点创建离线环境repo源

cat > /etc/yum.repos.d/local.repo << EOF

[local]

name=local

baseurl=

enabled=1

gpgcheck=0

EOF

yum clean all && yum makecache

# 测试

yum -y install docker-ce
