    Unable to connect to remote FTP server from Docker container using FTP client - Stack Overflow

    programmeradmin5浏览0评论

    I am running a service in a Docker container that needs to connect to a remote FTP server. While I can successfully connect to the FTP server from my host machine (using FTP clients like FileZilla or the command-line FTP client), the service in the Docker container fails to establish a connection.

    Here's the setup:

    • The service inside the Docker container needs to connect to the FTP server either at localhost or some test one as /
    • The FTP server works fine when I connect from my host machine.
    • I am using the following Docker setup:
    version: '3.8'

services:
  ftp-file-service:
    build:
      context: .
      dockerfile: ftp-file-service/Dockerfile
    container_name: ftp-file-service
    ports:
      - '8081:8081'
    networks:
      - common-network
    extra_hosts:
      - "host.docker.internal:host-gateway"
    depends_on:
      - redis
...

networks:
  common-network:
    driver: bridge

    Problem: The FTP client inside the container is unable to connect to the remote FTP server.

    What I have tried so far:

    • I checked that the FTP server is accessible from the host machine (FileZilla connects without issues).
    • I added the extra_hosts configuration to route the container's localhost to the host machine.
    • I tried using the bridge network mode and confirmed that the container has Internet access, but still cannot connect to the FTP server.

    Question: What is the correct configuration to enable the container to connect to an external FTP server from inside the container?
