docker 分离engine和client
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···
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
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.cnblogs.com": {}
},
"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

方法一：
可以去github上挨个下载(这样太麻烦了，可能还上不去这个网站)：传送门
方法二：
下载桌面版，解压开复制里面的文件
这种方法简单粗暴，补全后删除即可
下载链接：传送门，下载完成后，如下图：
双击打开后，访达中会有这样一个东西。
然后右击Docker.app，选择显示包内容，接着复制如下目录的文件到/Users/lanjx/.docker/cli-plugins(注意用户名，根据自己的实际路径来)
接下来给权限
sudo chmod +x /Users/lanjx/.docker/cli-plugins/*到这里就结束啦，重启终端，看看效果~
