Akegata / sftp-centos

Docker sftp image based on CentOS.

sftp

Fork of atmoz/sftp: Simple and easy to use SFTP server based on CentOS

Usage

• Define users and passwords in comma separated list with SFTP_USERS ("user1:pass1[:uid][:e],user2:pass2[:uid][:e]").
• Mount volumes in user's home folder.
• Supports encrypted password and optional UID specification.

The users are chrooted to their home folders, so it is important to mount the volumes in separate folders inside the user's home folder (/home/your-user/your-folder).

Examples

Simple (one user and one folder):

docker run \
    -e SFTP_USERS='foo:123' \
    -v "/sftp/share:/home/foo/share" \
    -p 2222:22 -d atmoz/sftp

Multiple users with specific UIDs and folders:

docker run \
    -e SFTP_USERS='foo:123:1000,bar:abc:1001' \
    -v "/sftp/share:/home/foo/share" \
    -v "/sftp/ebooks:/home/foo/ebooks" \
    -v "/sftp/http:/home/bar/http" \
    -p 2222:22 -d atmoz/sftp

Encrypted password and specified UID:

docker run \
    -e SFTP_USERS='foo:$1$xyz$jAlmRpcFe.aiPOIXET9GG/:1050:e' \
    -v "/sftp/share:/home/foo/share" \
    -v "/sftp/ebooks:/home/foo/ebooks" \
    -v "/sftp/http:/home/bar/http" \
    -p 2222:22 -d atmoz/sftp

Docker compose example

services:
  sftp-compose:
    image: akegata/sftp-centos
    container_name: sftp
    restart: unless-stopped
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      # Any $ in SFTP_USERS needs to be duplicated to be parsed correctly.
      - SFTP_USERS=<user>:<password>:<uid>:e,
                   <user2>:<password>:<uid>:e,
    volumes:
      - <host-dir>/upload:/home/<user>/pool/
      - <host-dir>/upload:/home/<user2>/pool/
    ports:
      - 2200:22/tcp # Allows HTTP access to the internal webserver.

Generate encrypted password

Use atmoz/makepasswd to generate encrypted password:
echo -n "your-password" | docker run -i --rm atmoz/makepasswd --crypt-md5 --clearfrom=-
