Hi, I'm trying to work out what I'm doing wrong. I'm trying to run under docker using a slightly modified version of the example docker-compose.yml file from the project readme. The only real change is that I'm trying to map data to a sub-directory of the working directory that holds my docker-compose file so that I can define my own environment variable settings. But when I run docker-compose up I get this traceback;

Starting lldap_lldap_1 ... done
Attaching to lldap_lldap_1
lldap_1  | Error: Could not write the generated server setup to file `/data/private_key`
lldap_1  |
lldap_1  | Caused by:
lldap_1  |     Permission denied (os error 13)
lldap_lldap_1 exited with code 1

So it looks like the container can't write to my lldata directory but I can't figure out why. Can anyone help out with suggestions?

My docker-compose.yml file is as follows. I've just starred out the secret and password valuesservices:

lldap:
  image: nitnelave/lldap
  ports:
    # For LDAP
    - "3890:3890"
    # For the web front-end
    - "17170:17170"
  volumes:
    - "./lldata:/data"
  environment:
    - JWT_SECRET=*******
    - LDAP_USER_PASS=********
    - LDAP_BASE_DN=dc=home,dc=arpa

And as soon as I posted this issue I figured out what I was doing wrong. I had copied lldap_config.docker_template.toml to my lldata directory and renamed it to lldap_config.toml but hadn't updated the entries that referred to the \data directory so on startup the code was trying to write to non-existent files.

Sorry, I spoke too soon. I was expecting the database and associated files to be written to my lldata folder but nothing is appearing there. The sample docker-compose file creates a named volume but I can't then figure out how to get my lldap_config.toml file into that volume. So, my question is how do I mount the container /data to a host folder so that on startup lldap will read my lldap_config.toml file. Thanks in advance for any assistance.

I just pushed a freshly baked new docker image just for you, with slightly better diagnostics when starting the server, please try it out.

With your docker-compose file above, you should have in your lldata folder the lldap_config.toml file. When the server starts, it will create the users.db file next to it.

Note that env variables should be prefixed with LLDAP_, I'll correct the README example.
