Error on container boot

[RiffyDivine]

Morning, so I had some issues getting this up and running. I have fixed most of said issues but I am not sure about this one. I am not sure what the permission issue is with the turnserver or how to correct it, unless that is normal. But also the error during initialization has me stumped right now. Anyone know how to fix it or even where I should start?

Added my compose file at the end in case the error is there.

Hi @RiffyDivine

thanks for open an issue.

The turnserver permission denied message is not pretty but it also does not has any impact. Btw, you can disable the turnserver if you set the environment variable COTURN_ENABLE: "false".

To your database error. My first question would be, if there is a homeserver.db file in your config directory? If yes, then have a look if the permission are 991:991. If yes, then please take a look into the homeserver.yaml file and share us the database part. It should looks similarly to this one:

database:                                                                                                                                                                                                                             
   name: sqlite3                                                                                                                                                                                                                       
     args:                                                                                                                                                                                                                               
        database: /data/homeserver.db 

Thanks. :-)

[RiffyDivine]

Thanks, but yes I believe I need the turn server to get it all up and running for the users I got. Mostly based on any attempt to get voip/streaming working so far have failed. Chat is fine.

But for the database it says this. But looking at what you posted, does the args need to be indented more since mine is inline with name line. I will go try that just to see.

database:
  name: sqlite3
  args:
    database: /homeserver.db

Well here was the output from moving things around.

The error you posted last means that you have an issue with your homeserver.yaml file, and by your comment I think that's because you miss and extra indent before args:

That should look like:

database:
  name: sqlite3
    args:
      database: /data/homeserver.db

Second: you really should consider using postgresql for your database rather than sqlite. That's not specific to this container, but general synapse advice. See here.

Third: if you decide to keep sqlite you'll want to make sure that the homeserver.db file you define in the homeserver.yaml is in a mapped volume, such that the database file remains outside of the container, otherwise you'll lose all the data of your server when updating/recreating your container.
