sftp
====

Easy to use SFTP (*SSH File Transfer Protocol*) server.

Usage
-----

- Define users and passwords in comma separated list with SFTP_USERS (syntax:
  `user:pass[:e][:[uid][:gid]][,...]`).
  - You must set custom UID and/or GID for your users if you want them to make
    changes to your mounted volumes with permissions matching your host
    filesystem.
- Mount volumes in user's home folder.
  - The users are chrooted to their home directory, so you must mount the
    volumes in separate directories inside the user's home directory
    (/home/user/**mounted-directory**).

Examples
--------

### Single user and volume

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

### Multiple users and volumes

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

### Custom UID and GID

```
SFTP_USERS='foo:123:1001:100'
```

Only custom GID:

```
SFTP_USERS='foo:123::100'
```

### Encrypted password

Add `:e` behind password to mark it as encrypted:

```
SFTP_USERS='foo:$1$0G2g0GSt$ewU0t6GXG15.0hWoOX8X9.:e:1001:100'
```

Tip: you can use makepasswd to generate encrypted passwords:
`echo -n 123 | makepasswd --crypt-md5 --clearfrom -`
