kubenetes and Centos 7 常见脚本

安装 salt

yum install -y https://mirrors.aliyun.com/epel/7/ppc64/Packages/s/salt-ssh-2015.5.10-2.el7.noarch.rpm \
https://mirrors.aliyun.com/epel/7/ppc64/Packages/s/salt-2015.5.10-2.el7.noarch.rpm

然后将节点列表添加到 /etc/salt/roster

禁止询问是否信任

echo "StrictHostKeyChecking no" >> /etc/ssh/ssh_config

节点统一安装 nfs 驱动

yum install -y epel-release nfs-utils fuse s3fs-fuse

统一挂载 nfs

salt-ssh '*' cmd.run "mkdir /mnt/share; mount -t nfs 192.168.187.17:/export/share/ /mnt/share"

安装 helm

wget --no-check-certificate https://www.4wei.cn/files/helm-v3.9.2-linux-amd64.tar.gz
gunzip helm-v3.9.2-linux-amd64.tar.gz
tar -xf helm-v3.9.2-linux-amd64.tar
mv linux-amd64/helm /usr/local/bin/
chmod +x /usr/local/bin/helm

安装 Kuboard (内建用户)

使用 Docker 安装

docker run -d \
  --restart=unless-stopped \
  --name=kuboard \
  -p 80:80/tcp \
  -p 10081:10081/tcp \
  -e KUBOARD_ENDPOINT="http://内网IP:80" \
  -e KUBOARD_AGENT_SERVER_TCP_PORT="10081" \
  -v /root/kuboard-data:/data \
  eipwork/kuboard:v3

使用 k8s 安装
