Looks like your database isn't up, because of which the Django app migh not have started at all.

Can you also show the output of:

$ docker logs mailman-web

It should have something relevant if the container didn't startup at all.

There is no logs directory at all:

cd /opt/mailman/web/logs -bash: cd: /opt/mailman/web/logs: No such file or directory

So it looks like no database was setup. My understand is the docker installation does that:

The default compose file do these things:

Run a wsgi server using uwsgi for the Mailman's Django based web frontend listening on http://172.19.199.3:8000/ . It will run 2 worker processes with 4 threads each. Run a PostgreSQL server with a default database, username and password as mentioned in the docker-compose.yaml . Run mailman-core listening an LMTP server at http://172.19.199.2:8024/ for messages from MTA.

Ok I just discovered the docker-compose-mysql.yaml file. I assume I can just use that file:

docker-compose-mysql -d

Is that correct? Do I need to remove the previous docker installation that I did using docker-compose.yaml?

Sorry for being so needy. This is the 2nd time I am installing an application using Docker. The first one was Discourse which had really good installation instructions. I am struggling with the instructions for Mailman 3 via Docker.

Yes, you can try using this and update the variables in the compose file similar to postgres.

Which variables are you referring to exactly?

If you update the environment variables to point to your local installation, you should be able to use just that instead of the the docker-version. You'd have to manually change the docker-compose.yaml file to use the on-host database though.

So I need to create the mysql database and username/password before running the docker installation?

Please explain "You'd have to manually change the docker-compose.yaml file to use the on-host database though." Even though I run docker-compose-mysql -d I still need to update the docker-compose.yaml file? See that is confusing for me. Again it is probably due to my inexperience in using docker.

I am happy to update the docs to be more friendly and useful if you can point out the specifics of what isn't clear. Please feel free to open an issue on Github if you feel something isn't clear :)

Thanks.

Ok I am trying this again. I am not sure why my last questions were not answered. Please let me know if I am doing something wrong in asking them. Here they are again:

Even though I run docker-compose-mysql -d I still need to update the docker-compose.yaml file? See that is confusing for me. Again it is probably due to my inexperience in using docker."

I think that is a legitimate question. There are two files being referenced here. If docker-compose-mysql.yaml has the correct setup then why do I need to manually change the docker-compose.yaml? It seems both files perform the same function except one references a Postgre DB and the other a MySQL DB.

The docker-compose files run a database inside a docker container as well. The difference between the "normal" and mysql version is the database being used. If you wish to run Mailman using docker with a database on the local host (not in a container) you will need to update the docker configurations to reflect that. The stuff you would need to change is:

• remove the database container from the compose file
• update the credentials to be able to connect to the database running on the host DATABASE_URL and DATABASE_TYPE. Note that each one of them exists twice!

There is no easy way to get the private IP address of the docker host in the compose-file. So you'll have to patch that in somehow. Here is an issue with pointers on how to do that https://github.com/docker/compose/issues/4092

As for your other issue: You don't need to setup anything yourself if you want to use docker for everything. It autocreates everything for you. You should change the credentials though before running it...

You are having trouble finding information because you want to partially use docker but leave the database on the host. If you want to tinker with how Mailman is supposed to be deployed using docker we can't start to document every possible thing you might want to change.

If you have specific issues with how to run them after reading https://asynchronous.in/docker-mailman/ please mention mention what part needs fixing/explanation

2. I was told to run docker ps. Here is the output from that:

Inspect it's logs (docker logs dockermailman_database_1) to see what's going on. I'd recommend removing all directories that contain the database stuff before trying again.

The rest of the issues is just because the database is not there...

The query came up:

chown: /var/lib/postgresql/data: Permission denied So your current user isn't allowed to write to the directories for the volumes in the docker-compose file.

Either provide the executing user with the privileges or change the location to somewhere the user can write to.

I bet it has something to do with selinux being enabled. I am disabling it now and rebooting the server.

Here is a 2nd unanswered question:

"So I need to create the mysql database and username/password before running the docker installation?"

It seems simple enough to answer. The current installation documents does not make that clear. I recommend that you update the docs to where the above question is answered, at least for those who are using MySQL.

Ok. I made some headway here. I got the container to launch. Still getting the original error message "connection refused". However this time the database is running. Here is the error I get when I run:

Can you show me how does your docker-compose.yaml looks like? Please remove anything sensitive like passwords or secrets.

This is a known error and has been fixed, but I am guessing that it isn't released yet, because of which you can still see this error. Can you open an issue here1 and I will fix it as soon as I can?

thanks, Abhilash

I have posted the error on Github. Did you see anything wrong with my docker-compose.yaml file?

I also have another question. For the HYPERKITTY_API_KEY setting, is there an API key I need to generate and retrieve from somewhere or do I just make one up?

Thanks, Brian

Is there a way to get this new release and how do I update the existing one with it?

Another question:

Should I update the following settings with my own custom ones?

POSTGRES_DB: mailmandb POSTGRES_USER: mailman POSTGRES_PASSWORD: mailmanpass

Or does the docker installation configure those automatically?

Sorry to dig up an old thread but was there any resolution to this? I've being trying the same thing but when I try to start the container get the same error:

[root@mailman-server docker-mailman]# docker-compose up -d Starting dockermailman_database_1 ... error

selinux is turned off on the server I'm using which is Centos 7 same as the OP.

The config files I've modified as mentioned in the documentation are: docker-compose.yaml in docker-mailman mailman-extra.cfg in mailman/core settings_local.py in mailman/web

Thanks!

Thanks!
