Docker image - ignoring configuration

[stephematician]

I was experimenting with isso on my local machine using docker (rootless, but I believe this is irrelevant), but I was not able to change the configuration when invoking the container.

Steps

I was able to get a comment box to appear using the following:

• docker command:

  docker run -d --rm --name isso -p 127.0.0.1:8080:8080 \
      -v /home/username/isso/config:/config \
      -v /home/username/isso/db:/db \
      ghcr.io/isso-comments/isso:release
  

• config in /home/username/isso/config/isso.cfg:

  [general]
  dbpath = /db/comments.db
  host =
      http://localhost:1313/

• and localhost:1313 being served by Hugo with <script> tags as per isso instructions.

However, I do not believe it was using the configuration I expect. For example, if I tried to use port to 8181 via:

• updated docker command:

  docker run -d --rm --name isso -p 127.0.0.1:8181:8181 \
      -v /home/username/isso/config:/config \
      -v /home/username/isso/db:/db \
      ghcr.io/isso-comments/isso:release
  

• updated config:

  [general]
  dbpath = /db/comments.db
  host =
      http://localhost:1313/
  [server]
  listen = http://0.0.0.0:8181

• and I updated the <script> tags to refer to port 8181.

The comment box doesn't appear (and I get CONNECTION RESET errors if i try to navigate to 127.0.0.1:8181/js/embed.js).

I can see that the isso process that was spawned (inside the container) is not watching port 8181 via netstat:

$ docker exec -it isso sh
# netstat -tlunp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      1/python3

If I try running isso manually within the container, then it does use the configuration I expect, e.g.:

$ docker exec -it isso sh
# source bin/activate
/isso # isso run &
/isso # 2024-10-16 23:34:45,199 INFO: Using configuration file '/config/isso.cfg'
2024-10-16 23:34:45,218 INFO: Using database at '/db/comments.db'
2024-10-16 23:34:45,220 WARNING: unable to connect to your website, Isso will probably not work correctly. Please make sure, Isso can reach your website via HTTP(S).

It is definitely listening to the port now, e.g. netstat.

/isso # netstat -tlunp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      1/python3

And the comment box is appearing.

Am I doing something wrong when I invoke docker? I tried argument -e ISSO_SETTINGS=/config/isso.cfg but it made no difference.

Also, if anyone has any hints about the WARNING that isso is giving me, that would be helpful <- I believe this is due to rootless docker, which might be tricky to overcome.
