Docker 18.09 离线安装

目录

{{TOC}}

背景环境说明

操作系统: Redhat 7.5 X86
内核: 3.10.0-862.el7.x86_64
需要离线安装docker 18.09

网上很多种方式,yum安装什么的,总是会缺各种包。不建议使用。 直接上大招, 使用binaries 直接安装。

官方二进制包安装文档

主要步骤

  1. 准备工作,下载bin包
  2. 配置Docker的一些配置文件
  3. 验证Docker

详细步骤

1. 检查ROOT权限(可选)

如果已经有管理员权限,可以跳过。

# vi /etc/sudoers

root ALL=(ALL) ALL 
k8sadmin ALL=(ALL) ALL  (添加本行)

确认可以执行执行 sudo 表示配置没问题。

2. 下载Docker离线安装包

二进制包,即可以直接使用的软件,无需再编译配置。但是需要选对平台,如X86 AIX等平台。

阿里云Docker镜像Bin包地址
这里选择正确的版本,选择18.09最新版本。

3. 准备Docker一些配置文件

创建一个目录,假设为: /home/k8sadmin/docker-install/

配置dasmon.json

在工作目录创建 daemon.josn,也可以直接配置/etc/docker/daemon.json文件,

{
    "insecure-registries": [
        "10.16.43.130:5080",
        "registry.scrcu.com:80"
    ],
    "registry-mirrors":[
        "https://d8b3zdiw.mirror.aliyuncs.com"
    ],
    "data-root": "/data/docker"
} 

daemon.json指定用户运行docker参数,常用的还有一些:

insecure-registries: 不使用https的镜像仓库
graph: docker运行时文件存档路径\(v18.06之前的版本可以用,后面用data-root替换)
log-driver: 日志驱动
data-root: 新版本 替换graph的新参数(v18.09)

配置docker.service

可以从其他docker安装后的文件/usr/lib/systemd/system/docker.service copy过来。 这里提供docker 18.09的范例,后续docker版本可能会变化:

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
#BindsTo=containerd.service.  — 无需containerd。
After=network-online.target firewalld.service
Wants=network-online.target

[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd -H unix://
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity

# Comment TasksMax if your systemd version does not supports it.
# Only systemd 226 and above support this option.
TasksMax=infinity

# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes

# kill only the docker process, not all processes in the cgroup
KillMode=process

[Install]
WantedBy=multi-user.target

好了到此你的文件夹应该有以下的文件列表:

# ls -1
daemon.json
docker-18.09.4.tgz
docker.service

4. 离线安装/配置Docker

创建Shell执行或者手动执行:

#:
echo " 1. unzip the docker bin."
tar zxvf docker-18.09.4.tgz
echo " 2. move docker* into /usr/bin "
cp docker/* /usr/bin/
#vi /etc/daemon.json
echo " 3. copy daemon.json, docker service into system "
mkdir /etc/docker
cp daemon.json /etc/docker/daemon.json
cp docker.service /usr/lib/systemd/system/docker.service
echo " 4. docker install successfully !, check docker info to see the result."

5. 启动验证

启动docker服务,设置开机启动服务。

systemctl daemon-reload
systemctl start docker 
systemctl enable docker

#查看docker返回信息
docker info 
#运行官方验证程序。
docker run hello-world
