docker及docker-compose一键安装部署

通过shell脚本一键部署docker/docker-compose

---

1. 部署环境

服务器	docker	docker-compose
Centos7.8	19.03.11	1.27.4
注：需要部署k8s的小伙伴这里要注意了，请部署1.20.0之前的版本，因为1.20.0已经替换docker为containerd

2. docker安装部署

• 添加docker镜像源

# 腾讯云 docker hub 镜像
# export REGISTRY_MIRROR="https://mirror.ccs.tencentyun.com"
# DaoCloud 镜像
# export REGISTRY_MIRROR="http://f1361db2.m.daocloud.io"
# 阿里云 docker hub 镜像
export REGISTRY_MIRROR=https://registry.cn-hangzhou.aliyuncs.com

• 创建以及编写docker download shell脚本

vi docekr-download.sh

#!/bin/bash

# 卸载旧版本
yum remove -y docker \
docker-client \
docker-client-latest \
docker-ce-cli \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine

# 设置 yum repository
yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# 安装并启动 docker
yum install -y docker-ce-19.03.11 docker-ce-cli-19.03.11 containerd.io-1.2.13

mkdir /etc/docker || true

#添加了log日志的大小及数量限制，防止日志过大占用资源
#当拥有私有docker镜像仓库(http)时，请自行添加配置"insecure-registries":["ip:post"]
cat > /etc/docker/daemon.json <<EOF
{
  "registry-mirrors": ["${REGISTRY_MIRROR}"],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m",
    "max-file":"3"
  },
  "storage-driver": "overlay2",
  "storage-opts": [
    "overlay2.override_kernel_check=true"
  ]
}
EOF

mkdir -p /etc/systemd/system/docker.service.d

# Restart Docker
systemctl daemon-reload
systemctl enable docker
systemctl restart docker

# 关闭 防火墙
systemctl stop firewalld
systemctl disable firewalld

# 关闭 SeLinux
setenforce 0
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

# 关闭 swap
swapoff -a
yes | cp /etc/fstab /etc/fstab_bak
cat /etc/fstab_bak |grep -v swap > /etc/fstab

# 重启 docker
systemctl daemon-reload
systemctl restart docker

#下载docker-compose
curl -L https://get.daocloud.io/docker/compose/releases/download/1.27.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose


docker version
docker-compose version

• 执行脚本

./docekr-download.sh
