I’m migrating a 15 year old community to discourse, and we’ve decided not to migrate the hundred thousand plus posts, rather selected ones of lasting value. On the old board, images are saved as [https://static.xxx/uploads/xxx.jpg](https://static.xxx/uploads/xxx.jpg). and we’ll keep that server alive post-migration. When moving posts with images, it’s not grabbing and making the thumbnail, no matter whether I wrap the images in () or not. It does it for the current session but when I force-reload the page or another user looks at it, we get the broken picture icon: ![Screen Shot 2020-02-04 at 9.30.58 AM](https://global.discourse-cdn.com/meta/original/3X/7/9/79d46ccb3a3888e06493f9399f1635a505a1bfec.png) The icon links directly to the picture on the static server, which is working fine. But thumbnails would be ‘nice’. The only thing I can think of is a firewall problem - both servers are in private IP space, and the firewall prevents an internal server from accessing another via an external IP. I _believe_ I’ve set this correctly in the host’s /etc/hosts file, but am NOT a docker expert. When I ping the static image server I get the correct internal IP address from regular command prompt. (note to self, enter the container and test from there) Is there something else I need to do to force static.xx to be the internal IP? External images when wrapped with () are working as expected with the lightbox. ---

You could have it talk to an internal DNS server? It depends on your layer 3 topology but that would stop all loopback chatter. ---

when i ping the asset server i get the internal ip is docker using an alternate host file? ---

Use` ./launcher enter app` to find out. ---

> [@Stephen](#): > > ./launcher enter app aha thats the issue. resolves to external ip. root@discourse-app:/var/www/discourse# cat /etc/hosts ``` 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters 172.17.0.2 discourse-app ``` Added, and… success! ---

Altering the hosts file in the container won’t persist between rebuilds. Better to troubleshoot your DNS chain than bodge it. ---

That’s an issue… although once the file has been brought into discourse, the original will no longer be referenced, right? ---
