This is my container config: http://pastie.org/10244604
This is the command generated when I run ./launch start app
/usr/bin/docker run -d --restart=always -e LANG=en_US.UTF-8 -e RAILS_ENV=production -e UNICORN_WORKERS=2 -e UNICORN_SIDEKIQS=1 -e RUBY_GC_MALLOC_LIMIT=40000000 -e RUBY_HEAP_MIN_SLOTS=800000 -e DISCOURSE_DB_SOCKET=/var/run/postgresql -e DISCOURSE_DB_HOST= -e DISCOURSE_DB_PORT= -e HOME=/root -e db_shared_buffers=128MB -e DISCOURSE_DEVELOPER_EMAILS=xxx@example.com -e DISCOURSE_HOSTNAME=forum.example.com -h prodhk-app -e DOCKER_HOST_IP=172.17.42.1 --name app -t -p 127.0.0.1:8080:80 -p 2222:22 -v /var/discourse/shared/standalone:/shared -v /var/discourse/shared/standalone/log/var-log:/var/log local_discourse/app /sbin/boot

(I excluded the detail related to SMTP config)
— Update 1 ----
I can see the shared folder in immediate current folder after entering the container, which has very long path, but not in “/”
$ ./launcher enter app

But this “shared” folder doesn’t contains any subfolder, such as postgres_backup, uploads…
- Another issue, may be related to this, is that some files of Discourse are changed the name:

The reply-post.png is changed to reply-post-2x.png. This makes images in our forum broken.
---- Update 2
I can access /shared folder if I use ./launcher ssh app to enter the container.
