A user, lspriwx, is experiencing issues with broken images on their Discourse site, running on Docker with version 2.4.0.beta11. They have configured their site to use port 8888, which is not supported for serving images, as explained by Stephen. The user’s main site is already using port 80, and they had to use an alternate port for Discourse. Stephen suggests following guides on meta for running Discourse alongside other sites, which may involve using a proxy server. The user acknowledges the response and will investigate further.

Serving images on :8888 like that isn’t supported.
You need to be using http on :80 or https on :443
You haven’t provided enough information to determine why you’ve configured things in this way, but if it’s intentional then it’s not a supportable configuration.
@Stephen Because Discourse is my sub site’s function(for forum). My main site is already using :80 port and i have to use another port.
Maybe i should use proxy server function or othere. but as you saw that i guess it’s problem of some URIs.
There are guides here on meta for running discourse alongside other sites.
Please use the search and follow one. We can’t help you with things as they are configured right now.
Thanks for reply 
hehe
