1、下载并安装

地址：https://hub.docker.com/editions/community/docker-ce-desktop-mac/

安装完成后，启动Docker，点击鲸鱼图标可显示docker的相关操作，如下图。

2、配置镜像加速

在国内访问默认的官方镜像速度较慢，可使用阿里云的镜像加速，注册阿里账号并申请容器服务之后，可在 这里 查看分配的镜像加速地址。然后在Docker的Preferences中配置加速地址。

3、注册Docker ID

完成上面两个步骤就可以正常使用docker，注册Docker ID是为了便于管理自己的镜像，注册地址：https://hub.docker.com/。

注册完成后可在Mac版Docker桌面工具中登录，并查看自己已有的镜像。

  

4、基本使用

4.2 搜索镜像

比如我们搜索nginx镜像，命令如下，搜索结果中标记“OFFICIAL”的为官方镜像，其他为用户自定义镜像，可根据实际需要选择。

docker search nginx

4.3 获取镜像

搜索到了需要的镜像之后可使用如下命令将镜像拉取到本地，类似于git拉取代码。

# 拉取指定版本xxx镜像
# docker pull nginx:xxx

# 拉取最新版本镜像 等价于docker pull nginx:latest
docker pull nginx

4.4 创建并启动容器

镜像拉取成功后，使用下面的命令启动nginx容器，容器内部的80端口已经映射到了本机的8080端口，所以启动成功后可以使用http://localhost:8080/访问docker容器内部nginx80端口映射的地址。

# -d 后台运行
# -p 8080:80 宿主机的8080端口映射到docker内部的80端口
# --name docker-nginx 启动后的容器名称为docker-nginx
docker run -d -p 8080:80 --name docker-nginx nginx

4.5 查看及停止容器

查看容器基本命令如下

# 查看运行中的容器
docker ps

# 查看所有容器 包括正在运行和已经停止运行的
docker ps -a

停止容器命令如下

# 通过id直接关闭容器
# docker kill a0fbf4519279
# 通过容器名称直接关闭容器
docker kill docker-nginx


# 通过id直接容器 默认等待十秒 超时强制关闭
# docker stop a0fbf4519279
# 通过容器名称关闭容器 默认等待十秒 超时强制关闭  等价于 docker stop -t=10 docker-nginx
docker stop docker-nginx

 

4.6 启动停止的容器

命令如下

# 启动容器可通过容器id或者容器名称
# 通过容器名称启动容器，如果已启动则忽略
docker start docker-nginx

# 通过容器名称重新启动容器，如果未启动则直接启动，如果已启动则关闭再启动
# docker restart docker-nginx
