注意MacOS 和Linux 修改Docker 容器配置方式不一样
本文中 centos7.2 是容器名称
获取容器id
# docker inspect 容器id/容器name $ docker inspect centos7.2 | grep Id "Id": "c05fc37444df75bbf0f3277ee36b9997c8ef401568d7c5149bb4aca1c25160b2"
进入Docker终端
# 停止容器 docker stop centos7.2 # 进入docker终端 # 如果卡住，直接回车 screen ~/Library/Containers/com.docker.docker/Data/vms/0/tty # 进入容器配置目录 $ cd /var/lib/docker/containers/c05fc37444df75bbf0f3277ee36b9997c8ef401568d7c5149bb4aca1c25160b2 # 容器配置目录文件 $ ls c05fc37444df75bbf0f3277ee36b9997c8ef401568d7c5149bb4aca1c25160b2-json.log checkpoints config.v2.json hostconfig.json hostname hosts mounts resolv.conf resolv.conf.hash docker-desktop:/var/lib/docker/containers/c05fc37444df75bbf0f3277ee36b9997c8ef401568d7c5149bb4aca1c25160b2 # 退出终端 # `ctrl+a+k`退出终端，输入y
修改端口配置
1、hostconfig.json 添加端口绑定
vi hostconfig.json # 搜索关键字 /PortBindings "PortBindings":{"8080/tcp":[{"HostIp":"","HostPort":"8082"}]} # 修改为 相当于运行参数 -p 8086:3306 "PortBindings":{"8080/tcp":[{"HostIp":"","HostPort":"8082"}], "3306/tcp":[{"HostIp":"","HostPort":"8086"}]}
2、config.v2.json 加上要暴露的端口
vi config.v2.json # 搜索关键字 /ExposedPorts "ExposedPorts":{"8080/tcp":{}} # 修改为 "ExposedPorts":{"8080/tcp":{}, "3306/tcp":{}}
说明：
8080/tcp是容器端口"HostPort":"8082"是宿主主机端口，就是MacOS的端口
重启docker（重要，让docker重新读容器的取配置文件）
# 启动容器 $ docker start centos7.2 # 再次查看端口映射，已经生效了 $ docker port centos7.2 3306/tcp -> 0.0.0.0:8086 8080/tcp -> 0.0.0.0:8082
