离线部署Docker

[TOC]

生产环境中一般都是没有公网资源的，本文介绍如何在生产服务器上离线部署Docker

括号内的字母表示该操作需要在哪些服务器上执行

Centos7 离线安装Docker

YUM本地文件安装（推荐）

推荐这种方式，是因为在生产环境种一般会选定某个指定的文档软件版本使用。

#下载清华的镜像源文件
wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo

sudo sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo

yum update

sudo yum list docker-ce --showduplicates|sort -r

复制到目标服务器之后进入文件夹安装(C-N)

yum install *.rpm

锁定软件版本(C-N)

下载锁定版本软件

可参考下文的网络源搭建

sudo yum install yum-plugin-versionlock

锁定软件版本

sudo yum versionlock add docker

查看锁定列表

sudo yum versionlock list

Loaded plugins: fastestmirror, versionlock
3:docker-ce-18.09.9-3.el7.*
versionlock list done

锁定后无法再更新

sudo yum install docker-ce

Excluding 1 update due to versionlock (use "yum versionlock status" to show it)
Package 3:docker-ce-18.09.9-3.el7.x86_64 already installed and latest version
Nothing to do

解锁指定软件

sudo yum versionlock delete docker-ce

Loaded plugins: fastestmirror, versionlock
Deleting versionlock for: 3:docker-ce-18.09.9-3.el7.*
versionlock deleted: 1

解锁所有软件

sudo yum versionlock delete all

YUM 本地源服务器搭建安装Docker

挂载 ISO 镜像搭建本地 File 源（AB）

# 删除其他网络源
rm -f /etc/yum.repo.d/*
# 挂载光盘或者iso镜像
mount /dev/cdrom /mnt

# 添加本地源
cat >/etc/yum.repos.d/local_files.repo<< EOF
[Local_Files]
name=Local_Files
baseurl=file:///mnt
enable=1
gpgcheck=0
gpgkey=file:///mnt/RPM-GPG-KEY-CentOS-7
EOF

# 测试刚才的本地源,安装createrepo软件
yum clean all 
yum install createrepo -y

根据本地文件搭建BASE网络源（B）

# 安装apache 服务器
yum install httpd -y
# 挂载光盘
mount /dev/cdrom /mnt
# 新建centos目录
mkdir /var/www/html/base
# 复制光盘内的文件到刚才新建的目录
cp -R /mnt/Packages/* /var/www/html/base/
createrepo  /var/www/html/centos/
systemctl enable httpd
systemctl start httpd

下载Docker-CE 镜像仓库（A）

在有网络的服务器上下载Docker-ce镜像

# 下载清华的镜像源文件
wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo
sudo sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo

# 新建 docker-ce目录
mkdir /tmp/docker-ce/
# 把镜像源同步到镜像文件中
reposync -r docker-ce-stable -p /tmp/docker-ce/

创建仓库索引（B）

把下载的 docker-ce 文件夹复制到离线的服务器

# 把docker-ce 文件夹复制到/var/www/html/docker-ce
# 重建索引
createrepo  /var/www/html/docker-ce/

YUM 客户端设置（C...N）

rm -f /etc/yum.repo.d/*
cat >/etc/yum.repos.d/local_files.repo<< EOF
[local_base]
name=local_base
# 改成B服务器地址
baseurl=http://x.x.x.x/base
enable=1
gpgcheck=0
proxy=_none_
[docker_ce]
name=docker_ce
# 改成B服务器地址
baseurl=http://x.x.x.x/base
enable=1
gpgcheck=0
proxy=_none_
EOF

Docker 安装（C...N）

sudo yum makecache fast
sudo yum install docker-ce docker-ce-cli containerd.io
sudo systemctl enable docker
