Docker Engine Quickstart

这是一个创建于 445 天前的主题，其中的信息可能已经有所发展或是发生改变。

比如宿主机的 IP 是 192.168.1.1
容器的 IP 是 20.20.20.20
容器可以直接通过 192.168.1.x:port 的方式
访问到宿主机局域网中的服务
怎么禁止这种访问, 同时支持容器访问公网?

带 cap=NET_ADMIN 运行
启动时把 private IP range 都 ip route add prohibit 掉

@ferock 可以用 com.docker.network.bridge.enable_icc: "false"试试，com.docker.network.bridge.enable_ip_masquerade: false 这个好像是用来禁止 nat 的

@momocraft 安全考虑 cap 能不给就不给吧，我上容器都是一律先非 root+cap-drop=ALL
