# 虚拟机运行状态下
vboxmanage controlvm "kubesphere_default_1628589687327_98836" natpf1 "kubesphere,tcp,,30880,,30880"

# 列出虚拟机下所有端口转发列表
vboxmanage showvminfo "kubesphere_default_1628589687327_98836" --machinereadable | awk -F '[",]' '/^Forwarding/ { printf ("Rule %s host port %d forwards to guest port %d\n", $2, $5, $7); }'

docker 修改 hosts方法

使用docker run运行一个新的容器的时候，通过参数 --add-host来添加域名和IP信息到容器的/etc/hosts文件中。例如：

1
docker run -it --name test --add-host=myhostname:10.180.8.1 debian

注意：--add-host参数最好在--name后面，避免启动报错

在docker-compose.yml文件中，通过配置参数extra_hosts实现。例如：

extra_hosts:
 - "somehost:162.242.195.82"
 - "otherhost:50.31.209.229"
