How to create ftp (vsftpd) in google cloud compute engine?

How to create ftp in google cloud compute engine? I can connect via SFTP without any issues, but my company is using a software to connect via FTP to download a XML file from the server. Unfortunately that software doesn't have SFTP connection facilities.

I saw lots of examples from the internet and to connect via SFTP not FTP.

Any idea's or tutorials ?

I found a way to do this, Please advice is there any risks.

apt-get install vsftpd libpam-pwdfile

nano /etc/vsftpd.conf

And inside the vsftpd.conf config file.

    # vim /etc/vsftpd.conf

    listen=YES
    listen_ipv6=NO
    anonymous_enable=NO
    local_enable=YES
    write_enable=YES
    local_umask=022
    nopriv_user=vsftpd
    chroot_local_user=YES
    allow_writeable_chroot=yes
    guest_username=vsftpd
    virtual_use_local_privs=YES
    guest_enable=YES
    user_sub_token=$USER
    local_root=/var/www/$USER
    hide_ids=YES

    listen_address=0.0.0.0
    pasv_min_port=12000
    pasv_max_port=12100
    pasv_address=888.888.888.888 # My server IP
    listen_port=211

Remove everything from the file and add these lines instead

auth required pam_pwdfile.so pwdfile /etc/ftpd.passwd

account required pam_permit.so

Create the main user that will be used by the virtual users to authenticate:

useradd --home /home/vsftpd --gid nogroup -m --shell /bin/false vsftpd

Once that is done we can create our users/passwords file.

htpasswd -cd /etc/ftpd.passwd helloftp

Next, add the directories for the users since vsftpd will not create them automatically.

mkdir /var/www/helloproject

chown vsftpd:nogroup /var/www/helloproject

chmod +w /var/www/helloproject

Finally, start the vsftp daemon and set it to automatically start on system boot.

systemctl start vsftpd && systemctl enable vsftpd

Check the status to make sure the service is started:

systemctl status vsftpd

    ● vsftpd.service - vsftpd FTP server
    Loaded: loaded (/lib/systemd/system/vsftpd.service; enabled)
    Active: active (running) since Sat 2016-12-03 11:07:30 CST; 23min ago
    Main PID: 5316 (vsftpd)
    CGroup: /system.slice/vsftpd.service
    ├─5316 /usr/sbin/vsftpd /etc/vsftpd.conf
    ├─5455 /usr/sbin/vsftpd /etc/vsftpd.conf
    └─5457 /usr/sbin/vsftpd /etc/vsftpd.conf

Finally add firewall rules to access via cloud.

Later I have changed my IP from 0.0.0.0 for more restriction
