背景

由于我个人电脑是2020款m1，16G，256G。一方面，平时除了运行多个浏览器，还有coding 编辑器等等，内存确实很紧张。其次呢，m1 是ARM的架构，所以构建的镜像是无法在X86的机器上运行的。所以我尝试将docker引擎和client分开。

第一步：下载二进制docker 客户端文件

二进制client下载链接：传送门

如果是苹果选择aarch64，进去后选择版本(我选择的是最新版本)

第二步：安装docker

注意：

1、除了要安装docker以外，还需要开启api端口，因为客户端需要和服务端通过远程端口进行通信

2、个人安装的最新版本

3、注意开启2375端口，确保能telnet通

docker安装文档：传送门

配置远程端口：

Docker 启动文件添加-H tcp://0.0.0.0:2375

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

···
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target docker.socket firewalld.service containerd.service time-set.target
Wants=network-online.target containerd.service
Requires=docker.socket

[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 fd:// --containerd=/run/containerd/containerd.sock
### 注意这里,我复制了一行
ExecStart=/usr/bin/dockerd -H fd:// -H tcp://0.0.0.0:2375 --containerd=/run/containerd/containerd.sock
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutStartSec=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
···

第三步：解压并添加环境变量

解压文件后如下：

添加环境变量

注意：
使用$PATH 命令查看环境变量

# 查看环境变量
$PATH

/Users/lanjx/opt/anaconda3/bin:/Users/lanjx/.nvm/versions/node/v16.18.0/bin:....太长了，忽略

# 将图中文件解压到环境变量对应的目录中
sudo cp DownLoads/docker/docker /usr/local/sbin/
sudo chmod +x /usr/local/sbin/docker

# 添加环境变量
vim .zshrc

# 将下面一句添加到文件末尾
...
export DOCKER_HOST=tcp://192.168.0.1:2375

修改文件

vim ~/.docker/config.json

{
        "auths": {                
                 "docker.e6gpshk.com:8443": {}
        },
        "credsStore": "desktop",        
        "currentContext": "default",
  			// 添加了下面这一行
        "hosts": ["tcp://192.168.0.1:2375"]
}

第四步：测试

到这里基本上已经差不多了，剩下的就是补全剩余的组件即可
