So I set up my first Discourse instance back in mid February. based on the all-in-one standalone Docker image. If I recall correctly the version was 1.3.0 beta1. I was in a bit of a hurry at the time and since I didn't have anything else running on the server I just let Discourse grab external port 80. Fast forward to yesterday and I finally decided that I needed to move Discourse to a different port so that I could put up an instance of Nginx outside of Docker and run some other web apps on the same VM. I made a copy of /var/discourse to a backup folder, stopped the container, edited app.yml to change the port, and then ran launcher rebuild app. And that's when things went horribly wrong leading to my post here. I'm thinking that the rebuild is updating my instance to 1.3.0 beta4 which includes some updates to the Postgresql instance within the container. That's where an error is occurring. A script is calling a chown on /shared/postgres_run and chown is returning a permission denied error. That then leads to a failed bootstrap. I'm an experienced *nix admin, but very new to Docker and Discourse so I've had no luck fixing this myself. Hopefully someone will have a good solution to this. I'm including the launcher output below.
[root@ip-172-31-32-99 discourse]# ./launcher rebuild app
