java - Apache ftpserver docker 容器

Question

我正在尝试在 docker 容器中使用 Apache ftpserver 运行 FTP 服务。容器启动没有问题并且能够登录。但是，它无法使用被动模式建立数据连接。到目前为止，它在本地运行，并且未设置外部 IP，因此我假设它获取内部本地 IP。

我尝试过设置或不设置外部 IP (setPassiveExternalAddress)，但没有成功。

有人成功使用 docker 容器运行 Apache ftpserver 吗？

这个 Dockerfile 对我有用(请参阅里面有关如何使用它的评论)

FROM openjdk:13-jdk-alpine

# Build this with:
# docker build -t "apache_mina_ftpserver:1.1.1" .

# Run this with:
# docker run -v /tmp:apache-ftpserver-1.1.1/res/home/ -p 2121-2199:2121-2199 -d apache_mina_ftpserver:1.1.1

# Then connect with
# ftp -p localhost 2121
# and log in with admin:admin

RUN wget https://archive.apache.org/dist/mina/ftpserver/1.1.1/dist/apache-ftpserver-1.1.1.zip
RUN unzip -q apache-ftpserver-1.1.1.zip

# configure additional passive ports
RUN sed -i 's#<\/ssl>#<\/ssl><data-connection><passive ports="2122-2199"\/><\/data-connection>#g' apache-ftpserver-1.1.1/res/conf/ftpd-typical.xml

EXPOSE 2121-2199
