Received bundler out of date message updating Discourse, so I built the container as advised. That seemed to work except that I got a message that there was already a server running on port 80. Tried rebooting the server. Now server’s throwing off a 500 error loading any page.
Admittedly I’m out of my depth with docker and discourse.
Tried rebuilding container bc… no good reason which generates the following error.
```
FAILED
--------------------
RuntimeError: cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' failed with return #
Location of failure: /pups/lib/pups/exec_command.rb:105:in `spawn'
exec failed with the params {"cd"=>"$home", "hook"=>"bundle_exec", "cmd"=>["su discourse -c 'bundle install --deployment --verbose --without test --without development'", "su discourse -c 'bundle exec rake db:migrate'", "su discourse -c 'bundle exec rake assets:precompile'"]}
```
I’m open to any suggestions. Thanks in advance.

What do the previous errors say?

Rerunning ./launcher rebuild app, the only errors…
```
database "discourse" already exists
...
role "discourse" already exists
...
column "like_notification_frequency" of relation "user_options" already exists
...
StandardError: An error has occurred, this and all later migrations canceled:
...
FATAL: xlog flush request 0/E91964B8 is not satisfied --- flushed only to 0/E9159030
```
…
and the process ends
```

Something _really_ bad is going on here. Your database is in a completely pantsed state. `xlog flush request is not satisfied` smells… diskspacey, maybe? At any rate, you’ve broken something real good. How’s your backups?
Please paste the output of `df -h`, `free -m`, `docker info` and `docker version`.

If you have a recent backup maybe this could help :

That worked. Thanks for all of your help @mpalmer and @Steven. The outcome wouldn’t have been as good without you.
I’m stuck with an original issue that started me down this path in the first place, but that’s another issue.
To be clear, I consider this issue to be resolved.
Cheers

Also that should have been `docker info` not `docker --info` sorry about that. I guess in the future it’s just
```
docker info
docker version
```
that seems to work on my box.

Yep that works for me. That was my fault.
`docker --help` clearly makes a distinction between options and commands.
