docker-ftpsmb

Docker image from base Ubuntu 18.04 that contains basic firewall (ufw), ftp (proftpd) and samba (v4) servers. The purpose is an anonymous ftp/smb server to store and distribute some files.

Environemtn variables

• OS_FTP_USER - default: ftp, specify a real os user to own the ftp directory
• DATA_DIR - default: /srv/ftp, the data directory
• FTP_USER, FTP_PASSWORD, default: empty, specify a virtual ftp user and password FIREWALL_ENABLED, default: empty, can be true` to enable ufw

Notes on the firewall

1. The containers need to be ran as priviledged for the firewall to work
2. The firewall is useless in the context of Kubernetes deployment

Sample configs

1. The etc directory contains some sample config files for:
   • ufw: allow some ip subnets
   • samba: use an anonymous share mapped to /srv/ftp
   • proftpd: use anonymous access to /srv/ftp
2. These sample configs are mapped at container runtime, can be loaded as configmaps in Kubernetes as well.
