Exited with Code 252 when using own TLS certificate

[Hannes Leutloff]

Hi 👋

I want to run pure ftpd with my own TLS certificate. I got it via let's encrypt and it is valid. My docker-compose.yaml looks like this:

version: '3.7'

services:
  ftp:
    image: stilliard/pure-ftpd
    ports:
      - "21:21"
      - 30000-30009:30000-30009
    volumes:
      - ./data:/home/ftpusers
      - ./users:/etc/pure-ftpd/passwd
      - ./tls-cert.pem:/etc/ssl/private/pure-ftpd.pem

I've cleaned the data and users volume before starting.
I've checked the certificate file in the container and it shows up belonging to fptuser:ftpgroup with permissions 600 and with the correct content.

Am I missing something here?

Thanks in advance and kind regards,

Edit: I forgot to attach the output when running the service:

> docker-compose up     
Starting ftp_ftp_1 ... done

I am getting the same error without using tls,

version: "3"
services:
  ftp:
    container_name: ftp
    image: stilliard/pure-ftpd:latest
    # volumes: # remember to replace /folder_on_disk/ with the path to where you want to store the files on the host machine
      # - "/home/myuser1:/home/myuser1"
    ports: 
      - 21:21
      - 8192-8200:8192-8200
    network_mode: host
    environment: 
      PUBLICHOST: localhost
      FTP_USER_NAME: myuser1
      FTP_USER_PASS: 123123
      FTP_USER_HOME: /home/myuser1
      FTP_PASSIVE_PORTS: 8192-8200

output:

ftp exited with code 252

please let me know if I am missing something,
if there is a bug, and would like help to fix it, I can gladly help out
thanks :)

I found my mistake and it was TLS related. I don't know what this has to do with @codexetreme's issue.

The documentation made it not entirely clear to me, in what format the TLS certificate had to be provided, so I just copied my Let's Encrypt certificate file to the given path, which look like this:

-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

This did not work. Then I tried the Let's Encrypt key file, which looks like this:

-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----

This also did not work. After some digging in forums I realized, that I had to combine the two. So now my /etc/ssl/private/pure-ftpd.pem file looks like this:

-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

And now the server starts fine.

@codexetreme you should probably open a separate issue for your problem.
