Linux Shell开发功能点

背景

需要操作一批次服务器安装Docker

功能特色

一键执行

bash <(curl -s -L http://server.com/installDocker.sh) MemberNode

参数传递hostname修改

if [ ! -n "$1" ] ; then

    echo "no hostname given!"

    exit

fi

# modify hostname

sudo sed -i "1c 127.0.0.1\tlocalhost\t$1" /etc/hosts

cat << EOF > /etc/hostname

$1

EOF

hostname $1

NvidiaDocker安装

#sudo adduser node sudo >&/dev/null

sudo apt install selinux-utils

setenforce 0

sudo ufw disable

# install docker

sudo swapoff -a

sudo sed -i 's/.*swap.*/#&/' /etc/fstab

sudo apt-get update

sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common

curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

sudo apt-get install docker-ce=18.06.3~ce~3-0~ubuntu

sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

sudo apt-get -y update

sudo apt-get -y install docker-ce

sudo systemctl enable docker

# make docker use GPU

distribution=$(. /etc/os-release;echo $ID$VERSION_ID)

sudo curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -

sudo curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit

sudo systemctl restart docker

sudo apt-get install -y nvidia-docker2

sudo pkill -SIGHUP dockerd

cat << EOF > /etc/docker/daemon.json

{

 "default-runtime": "nvidia",

    "runtimes": {

        "nvidia": {

            "path": "nvidia-container-runtime",

            "runtimeArgs": []

        }

    },

  "exec-opts": ["native.cgroupdriver=systemd"],

  "log-driver": "json-file",

  "log-opts": {

    "max-size": "100m"

  },

  "storage-driver": "overlay2"

}

EOF

# change docker daemon

sudo systemctl restart docker

K8s安装

# install k8s

sudo apt-get update &&  sudo apt-get install -y apt-transport-https

sudo curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key  add -

cat << EOF > /etc/apt/sources.list.d/kubernetes.list

deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main

EOF

apt-get update && apt-get install -y kubelet=1.18.1-00 kubeadm=1.18.1-00  kubectl=1.18.1-00

kubeadm join [HOST]:6443 --token TOKEN --discovery-token-ca-cert-hash sha256:TOKEN

sudo pkill -SIGHUP dockerd | sudo systemctl enable kubelet && systemctl start kubelet

远程镜像文件下载

mkdir working

sudo apt-get install sshpass

sshpass -p '123456' scp  -o StrictHostKeyChecking=no root@192.168.0.1:/home/node1/working/IMAGE.tar /root/working/

导入镜像文件

docker load -i working/IMAGE.tar

脚本自删除

rm -rf installDocker.sh

完成后关机

sudo halt -p
