环境以及版本

• Ubuntu-22.04
• wsl2 （Windows sub Linux version 2）
• Docker 24.0.7

1. 下载

docker 离线安装包下载地址

下载页

2. 解压安装包

tar -zxvf docker-24.0.7.tgz

3. 将 docker 可执行文件复制到 /usr/bin/ 目录下

cp docker/* /usr/bin/  

可执行文件包含：containerd containerd-shim containerd-shim-runc-v2 ctr docker dockerd docker-init docker-proxy runc

4.编辑docker.service 设置开机启动

编辑 docker.service 文件vim /usr/lib/systemd/system/docker.service

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service containerd.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 --exec-opt native.cgroupdriver=systemd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
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 support 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
OOMScoreAdjust=-500

[Install]
WantedBy=multi-user.target

启动程序，并设置开机自动启动，systemctl restart docker && systemctl enable docker.service

5. 安装完成，验证结果

systemctl status docker

验证结果

docker version

验证结果2

其实可以看到，以离线的方式安装 docker 很简单，而且相比较用 yum 那种在线一键安装方式，离线安装可以巩固下 Linux 的相关知识，比如 可执行文件要放 /usr/bin 目录下 、Service 如何去配置 、systemctl 命令。
建议进阶玩家可以多试试离线安装的方式。
