hello there,
my forum goes down every time i do ./launcher rebuild app.
I have attached screen shot of what error it gives.

If I’m understanding correctly, the error message says that there is a problem on line 9.
Try typing this command:
cat -n containers/app.yml
That will print out the contents of the file with line numbers, and you can check line 9 for syntax errors.
It would probably be a good idea to run that chmod command mentioned in the output too, though it isn’t related to the error.

Well, nano -l is much easier way to find right line and fix it right away 
If you haven’t change too much app.yml line 9 is just before templates: — can there be something strange as extra whitespace?
But one thing I’ve learned about YAML is there can be a whitespace almost anywhere, missing space, missing quote or wrong type - and error is pointing to wrong place.
I would say it is easier delete app.yml and do setup again.

I have removed that line 9 items completely but still it says line 9 is syntax error.

I would first do backup, if there is some content. And after that:
cd /var/discourse
mv containers/app.yml .
./discourse-setup

No. But that’s why you have done full backup first.
But you can give a try for this too:

Something it is.
But you can copy&paste your app.yml here as it is. Then someone wiser could take a look. Because now no one knows what there is or is not.

Can you share your full app.yml without secure informations (passwords etc…)?

I think this shouldn’t be the beginning of the file:
hooks: after_code: - exec: cd: $home/plugins cmd: - sudo -E -u discourse git clone https://github.com/discourse/docker_manager.git - sudo -E -u discourse git coe tp/gtu.c/dcusedcu-pile-rti
And there are two missing lines under LANG: en_US.UTF-8 line.
LANGUAGE: en_US.UTF-8
# DISCOURSE_DEFAULT_LOCALE: en
Maybe there are more I didn’t notice but here is the default file and you can compare.
Very first actual line starting hooks: can’t be right. It should be something like
hooks:
after_assets_precompile:
- exec:
cd: $home
cmd:
- sudo -E -u discourse bundle exec rake s3:upload_assets
- sudo -E -u discourse bundle exec rake posts:rebake
after_code:
- exec:
cd: $home/plugins
cmd:
- git clone https://github.com/discourse/docker_manager.git
Well, not exacly like that because this is from mine, but lines, intends etc should be similar.

You overrun me 
What do you think — would new ./discourse-setup be the fastest and easiest way to fix that mess?
