  --name pure-ftpd-mysql \
  slavko7/pure-ftpd-mysql:latest

Docker Compose

See docker-compose.yaml.

Parameters

  • --network=host: Use host network. If omitted, you need to map ports for passive mode (e.g., -p 30000-31000:30000-31000). Note that non-host mode can be slow if the port range is large.
  • -e PUBLIC_IP="127.0.0.1": Public IP for passive mode.
  • -e PORT_RANGE="30000:30007": Port range for passive mode.
  • -e RUN_ARGS="-o -Y 2 -A -J HIGH -E -j": Arguments for pure-ftpd-mysql service (default shown). Refer to https://linux.die.net/man/8/pure-ftpd for more options.
  • -v /home/dyedfox/ssl:/etc/ssl/private: Path to your SSL certificate.
  • -v /home/dyedfox/ftpdata:/home/ftpdata: Host volume path for storing uploaded files.
  • -v /home/dyedfox/ftpdata/uploadscript.sh:/etc/uploadscript.sh: Path to the upload script. For more info, see: https://linux.die.net/man/8/pure-uploadscript
  • -v /home/dyedfox/ftpdata/mysql.conf:/etc/pure-ftpd/db/mysql.conf: Path to MySQL configuration file.
  • --restart always: Always restart the container.
  • --log-driver syslog: Map logging to the host system.
  • --name pure-ftpd-mysql: Name of the container.

Workflow Examples

Create Users

User 1:

INSERT INTO `users` (`User`, `Password`, `Uid`, `Gid`, `Dir`)
VALUES ('ftpuser1', 'sUperSecretP4as$word', '1004', '1004', '/home/ftpdata/ftpuser1');

User 2:

INSERT INTO `users` (`User`, `Password`, `Uid`, `Gid`, `Dir`)
VALUES ('ftpuser2', 'sUperSecretP4as$word', '1004', '1004', '/home/ftpdata/ftpuser2');

Note on User Permissions

In mysql.conf, the MYSQLDefaultUID parameter is set to 1001, which defines the default uid:gid for uploaded files. If 1000 is the host system user, the directories ftpuser1 and ftpuser2 would have 1001:1001 uid:gid attributes.

Example directory structure:

cd /home/
ls -lah
total 12K
drwxr-xr-x 1 root root 4.0K Aug 10 09:00 .
drwxr-xr-x 1 root root 4.0K Aug 10 09:00 ..
drwxrwxr-x 4 1000 1000 4.0K Aug 10 11:50 ftpdata
cd ftpdata/
ls -lah
total 24K
drwxrwxr-x 4 1000 1000 4.0K Aug 10 11:50 .
drwxr-xr-x 1 root root 4.0K Aug 10 09:00 ..
drwxr-xr-x 2 1001 1001 4.0K Aug 10 11:53 ftpuser1
drwxr-xr-x 2 1001 1001 4.0K Aug 10 09:00 ftpuser2
-rw-rw-r-- 1 1000 1000 431 Aug 10 11:50 mysql.conf
-rw-rw-r-- 1 1000 1000 61 Aug 10 08:47 uploadscript.sh

Delete User

DELETE FROM `users`
WHERE `User` = 'ftpuser1'
  AND `Password` = 'sUperSecretP4as$word'
  AND `Uid` = '1004'
  AND `Gid` = '1004'
  AND `Dir` = '/home/ftpdata/ftpuser1';

Update User

UPDATE users
SET Password = 'sUperSecretP4as$word',
    Uid = 1000,
    Gid = 1000,
    Dir = '/home/ftpdata/ftpuser1'
WHERE User = 'ftpuser1';
