Hello! I have been struggling through a few tutorials on getting a lemmy instance to work correctly when setup with Docker. I have it mostly done, but there are various issues each time that I do not have the knowledge to properly correct. I am familiar with Docker, and already have an Oracle VPS set up on ARM64 Ubuntu. I already have portainer and an NGINX proxy set up and working okay. I have an existing lemmy instance “running” but not quite working. My best guess here would be to have someone assist with setting up the docker-compose to work with current updates/settings, as well as the config.hjson.

TIA, and I cant wait to have my own entry into the fediverse working right!

    I believe I have the simple set up for the NPM reverse proxy. Just as you say, it points to the docker address of the lemmyInstance NGINX. I can get to my instance with HTTPS secured and good. Just getting errors when communicating to other instances. I can only imagine it is web socket related, but I am not familiar enough to look at the proxy configs and determine what might be wrong with it unfortunately. I might need to try and find someone to essentially look through it with me in real time.

      from the logs it seems that lemmy docker does not communicate with outside servers.

      also i have a bit different config for lemmy.hjson

      {
  # for more info about the config, check out the documentation
  # https://join-lemmy.org/docs/en/administration/configuration.html

  setup: {
    # username for the admin user
    admin_username: "adminuser"
    # password for the admin user
    admin_password: "adminpassword"
    # name of the site (can be changed later)
    site_name: "group.lt"
  }

  opentelemetry_url: "http://otel:4317"



  # the domain name of your instance (eg "lemmy.ml")
  hostname: "group.lt"
  # address where lemmy should listen for incoming requests
  bind: "0.0.0.0"
  # port where lemmy should listen for incoming requests
  port: 8536
  # settings related to the postgresql database
  # address where pictrs is available
pictrs: {
    url: "http://pictrs:8080/"
    # api_key: "API_KEY"
}
  database: {
    # name of the postgres database for lemmy
    database: "lemmy"
    # username to connect to postgres
    user: "lemmy"
    # password to connect to postgres
    password: "lemmy"
    # host where postgres is running
    host: "postgres"
    # port where postgres can be accessed
    port: 5432
    # maximum number of active sql connections
    pool_size: 5
  }
#  # optional: email sending configuration
  email: {
#    # hostname and port of the smtp server
    smtp_server: "postfix:25"
    smtp_from_address: "from@group.lt"
    tls_type: false
  }


}

      also check in admin interface if federation is enabled and you do not blacklist instances

      (https://lemmy.bulwarkob.com/admin) and maybe you can try to enable federation debug mode for awhile

        The differences I see are the otel link, and the TLS setting:

          # Whether the site is available over TLS. Needs to be true for federation to work.
  tls_enabled: true

        I see you dont have it on there, which I would assume means you cant be federated? I have added the otel link and enabled the debug mode. Federation is already enabled and the instance is set to “ALL”. Still no luck on this end. Same status, except now im not getting any log errors in the container logs (Viewed from Portainer).

        Including this in case it is a possible issue: federation enabled, host is lemmy.bulwarkob.com

        Starting http server at 0.0.0.0:8536

          also pictrs: { url: “http://pictrs:8080/” # api_key: “API_KEY” }

          about tls setting - don’t remember why i have removed it, but group.lt federates fine. not sure about what you mean instance set to ALL.

          what about network isolation in portainer? maybe it is on?

            I see my Pictrs appears to be the same as what you had sent over. Protainer network isolation does not appear to be in place. All are bridged networks, and I would assume access issues would be more encompassing if that were a direct correlation to the issue. Im still betting on User Error for configuration so far. Being myself, of course.

              well probably you are right about the user error, but from the logs it seems that it cannot reach other instances - can you enter the shell of the container and check if you are able to ping/curl https://group.lt for example? and network isolation is a checkbox in portainer, according to docs.

              for the federation itself i have also experienced it not working, when my nginx config was pointing wrongly to lemmy and lemmy-ui depending on the headers.

              as i have said before - i can reach your instance from my lemmy, but don’t receive anything back.

                It would seem it was called “Internal” as opposed to isolated on my Portainer. That appears to have been it though. I can get to other communities now. Still having disparity with posts and comments showing up, but Im hoping that will be something to update in time.
