Lemmy on Docker - Postgre Authentication Fail
  • Thank you! I did figure that out as I got further along into this... so much new stuff to learn!!

  • Lemmy on Docker - Postgre Authentication Fail
  • I learned something interesting in doing some more testing...

    Using the -W option does indeed prompt for a password, but it accepts any value entered at the password prompt. In order to actually authenticate with a password when using psql, you must modify the pg_hba.conf file to use scram-sha-256 as the method for type local.

    When I do this, I am unable to authenticate (both while using my actual password, and also while using a password of "test".

    And then I figured out the problem.

    In my docker-compose.yml, I had put single quotes around my postgres password, thinking this would be safe per my understanding of this question. However, just to check, I tried logging in to psql using the password 'test'. Sure enough, it worked.

    I found another stack exchange with some different advice on strings in yaml: https://stackoverflow.com/questions/53082932/yaml-docker-compose-spaces-quotes

    So, I tried my password again, without the single quotes... and it worked.

    Perhaps this will help somebody beating their head against the wall in the future.

  • Turns out, unless you update pg_hba.conf to force password use, using the -W option prompts for a password, but authenticates with any value entered.

  • Lemmy on Docker - Postgre Authentication Fail
  • If you change the username for the db both for postgres and lemmy, do you get a different error about the new username?

    I tried this... updated the user to lemmy1. The error message does indeed change to reflect the new user.

    Super frustrating!

  • Lemmy on Docker - Postgre Authentication Fail
  • Yeah the name you want for the database host is postgres, or whatever the container is named in the docker-compose.yml.

    I was curious about this, and it turns out both work. I tested by pinging both postgres and lemmy_postgres_1, and both responded with the same IP address. Good to know, but I did go ahead and change it back to postgres

    Maybe try a very simple password temporarily like test, rebuild the postgres container/delete the volumes and see if it works.

    I did this, and I'm still getting the same error, so obviously something is wrong.

  • Lemmy on Docker - Postgre Authentication Fail
  • This makes sense, and I do have a dollar sign in my password...

    However, I have confirmed that postgres does in fact parse the password correctly, as I can log in with the defined username/password combo directly using psql

    So I think that disproves this theory, doesn't it?

    edit: I tried getting rid of the dollar sign just in case... unfortunately I'm still getting the same error

  • Lemmy on Docker - Postgre Authentication Fail
  • Thank you for enlightening me on the -W option in psql. I have successfully logged in using the expected password for lemmy. This points to something with the connection string. According to the error log, the connection string being used is:

    postgres://lemmy:<my percent-encoded password>@postgres:5432/lemmy
    

    As far as I can tell, the percent encoding is correct. Any ideas how to troubleshoot this further?

    edit: it just occurred to me that my container name is lemmy_postgres_1, not postgres as was entered in my lemmy.hjson file. Let's see if changing that will work...

    edit2: no, that had no effect. I'm getting the authentication error for user lemmy on both the lemmy container and the postgres container. :(

  • Lemmy on Docker - Postgre Authentication Fail
  • Frustratingly, when you use psql on the terminal, it does not prompt you for a password. So I'm still not sure if the password works or not :(

    Ahh, ok... if you add the -W option when logging in to psql (psql -U lemmy -W), it will prompt for the password.

    The password works! So, apparently it's something with the connection string.

  • Lemmy on Docker - Postgre Authentication Fail
  • Username definitely matches!

    And yes, I have several special characters, but the password is surrounded by single quotes in docker-compose.yml, so that should not matter, right?

  • Lemmy on Docker - Postgre Authentication Fail
  • I don't know how to do this yet, but this will be the first thing I try this morning.

  • Lemmy on Docker - Postgre Authentication Fail

    I'm trying to get Lemmy up and running on an Ubuntu 22.04 host. I've followed this guide supplemented by googling.

    I can actually get to the front end, but it gives me "There was an error on the server." When I dig into the logs, I see this:

    "thread 'main' panicked at 'Error connecting to postgres://lemmy:<my pg password>@postgres:5432/lemmy: FATAL: password authentication failed for user \"lemmy\"\n","stream":"stderr","time":"2023-06-26T03:14:17.47460915Z"}

    The only thing I can find about this error related to Lemmy is this thread, which indicates that the password was not defined in the docker-compose.yml file prior to starting the containers. I have since redone the configuration three times, each time deleting the volumes folder and double-checking that my postgre password is correct both in docker-compose.yml and lemmy.hjson.

    Any ideas what might be the problem? Thank you kindly for any help you can provide!

    [Resolved] Trying to set up my own Lemmy server, but I think I'm in over my head
  • I got it going... the main problem was that the ports for the proxy container were defined in a confusing way. Rather, the port definition should be symmetrical (e.g. 1236:1236) and not conflated with the lemmy server port (8536). Then, the nginx_internal.conf should be set to listen on 1236 only.

  • [Resolved] Trying to set up my own Lemmy server, but I think I'm in over my head
  • Do you mind sharing what exactly you changed in order to get it to work? I got nginx_internal.conf installed, but did not make any changes to it. I'm not able to get the UI using http://<ipaddress>:1236

    I'm not a complete newb when it comes to nginx, but I'm having a hard time understanding what all the different parts are here. For instance, what is the lemmy-ui container for? Is that what needs to be exposed for me to access the UI? If so, I don't see any port mapping the in container definition, so is it hard-coded to use a specific port?

    Any help you can provide is greatly appreciated!

    Wall-Mount Decorative Lighting

    Does anybody have any ideas for some decorative but functional lighting to go above my computer monitor?

    I've noticed that my image on Zoom calls is fairly dark, and I think some lighting on the wall above my monitor would help. However, the standard utilitarian webcam lighting (like the ring) aren't really what I want to be looking at all day.

    Any and all ideas are welcome!

    What are Gambits that everyone should know about?
  • If you're a 1. d4 player, you need to know the Englund Gambit

  • Once I get to the middle game I can handle myself (around lichess 1900) but I'm only doing 2 openings and its getting boring.
  • For whatever my opinion is worth (I'm ~1350 blitz on lichess), if you're finding your openings boring, then just try something new. For me, it helps to keep in mind that the goal is to have fun, NOT to maintain a certain Elo.

  • is it better to use subdomains or paths?
  • I don't know for sure... but my instinct is that NAT reflection is moot in that case, because your connection is going out past the edge router and doing the DNS query there, which will then direct you back to your public IP. I'm sure there's somebody around that knows the answer for certain!

  • is it better to use subdomains or paths?
  • If your router has NAT reflection, then the problem you describe is non existent. I use the same domain/protocol both inside and outside my network.

    I would occasionally pop into the LiveSound and AudioEngineering subreddits. Is there any interest in hosting those here? They seem to fit in with the theme of this server. Just a thought!
