Hi all -- really need some help. I'm tech literate, but definitely not a sysadmin or dev.

I'm following the tutorial at "Olay's Farmland" at https://www.olay.xyz/2018/01/01/deploy-mailman-3-on-aws-using-docker/ which seems to be a clone of the same content here https://xiaoxing.us/2018/01/01/deploy-mailman-3-on-aws-using-docker/

Easy enough to get most of the way ... set up EC2 instance, configure SES and add DNS settings with DKIM etc. Set up Postfix, test it. All working groovy.

I run through the how to all the way through setting up the containers and firing it up. This is where things start to get funky.

Once the docker-compose is run, I run "curl http://172.19.199.3:8000/postorius/lists/" to test. First time it said it couldn't connect to database. So I nuked and restarted from scratch. Second time it said the same thing... was reading around the place and tried again, and then reran that curl and it worked -- gave me html from a page. But the VM started running slowly --taking forever to follow keypresses.

Eventually became unresponsive. So I rebooted the machine via AWS console, and docker ps showed only the postgres db running. docker-compose ps shows Name Command State Ports

docker-mailman_database_1 docker-entrypoint.sh postgres Up 5432/tcp
mailman-core docker-entrypoint.sh maste ... Exit 255 8001/tcp, 8024/tcp mailman-web docker-entrypoint.sh uwsgi ... Exit 255 8000/tcp, 8080/tcp

So rebuilt the container -- same thing. It looks and feels like its running out of memory.

I used the compose file from https://gist.githubusercontent.com/Yexiaoxing/833bfcc5d3e4e0c06a8b7f0bac7c4c... (with appropriate edits).

I have no idea how to proceed from here...

Go to logs...

Partial log (they're LONG)

docker logs docker-mailman_database_1 The files belonging to this database system will be owned by user "postgres". This user must also own the server process.

The database cluster will be initialized with locale "en_US.utf8". The default database encoding has accordingly been set to "UTF8". The default text search configuration will be set to "english".

Data page checksums are disabled.

Success. You can now start the database server using:
