We run a discourse at discourse.lubuntu.me. It is configured to have that as its base URL.
However, internally, the system is getting 500 errors with its internal certificate.svg links and the discobot builtin for greeting users.
SocketError (Failed to open TCP connection to discourse.lubuntu.me:443 (getaddrinfo: Name or service not known))
/usr/local/lib/ruby/2.6.0/net/http.rb:949:in `rescue in block in connect'
This is behaving like it’s unable to do a DNS lookup inside the container running Discourse. Is there a way to fix this issue or better debug it?
Have you tried resolving addresses from inside/outside the container?
How was this instance installed?
This instance was installed following the installation guides here: https://github.com/discourse/discourse/blob/master/docs/INSTALL.md
So a straight Docker installation on Ubuntu as a host system.
The host system can resolve domains without issue, but it appears that because LXD also runs on the host system it’s intercepting all DNS requests. I’ll have to fix that in a bit, because LXD handling DNS is breaking resolutions.
THIS SAID, going into the container and forcing it to recognize itself as the domain returns a “Connection Refused” - so I’ve repointed to the ‘internet facing’ reverse proxy that serves HTTPS here, which seems to work. BUT this required going into
/etc/hosts to do it. I’ll have to see if there’s a way to ‘force’ an entry into there during the docker container startup process, but that’s a task for later as it’s ‘working’ for now.
