Hi guys, bootstrapping my web container is failing at assets:precompile

Any idea what’s wrong?

2

Did you do anything weird / custom in the Docker container?

3

Not particularly. I’ve deployed the exact same setup before. Re-running it is causing trouble :confused:

4

Is there some sort of security issue? what does the container config look like?

My guess is that somehow you changed permission on the host for the uploads directory shutting down access to it?

I’m using Ansible to automate stuff, hence the {{ vars }}

Is it possible to enter the web container to snoop on things even though it failed to bootstrap?

7

Nope, the container doesn’t “exist” anymore.

What do the permissions on /var/discourse/shared/web and subdirectories look like?

8

Thanks @riking for pointing me in the right direction. I had the /var/discourse/shared/web directory owned by an app user before running bootstrap (created when I copied SSL files into /var/discourse/shared/web/ssl before running bootstrap). Didn’t realize a link meant that permissions were shared too.

Indeed my own problem, sorry for taking everyone’s time!
