Hi All,
(Note that I have deliberately broken all domain names by inserting whitespace because they are getting detected as links, and as a noob I cannot post >2 links in a post)
I am trying to install discourse on a redhat VM at my work.
I have the following constraints:
- Host has no direct access to internet. Access is only via http/https proxy
- Host cannot resolve external DNS names (this is handled via the proxy)
yum, git, docker on the host are all configured to use the proxy.
I have discovered that I can pass the installer docker arguments, but these do not seem to get used in all locations.
I hope that someone on the forum can give me a pointer to progress?
I have observed that the installed needs to be able to connect to github .com and to rubygems .org.
Based on this I am using the following command to bootstrap with static host mappings for github and rubygems, and passing https proxy env variable:
./launcher bootstrap app --docker-args "--add-host github.com:192.30.253.113 --add-host rubygems.org:151.101.2.2 --add-host myproxy:10.10.10.10 -e HTTPS_PROXY=https://myproxy:8080"
The problem is that only github can be contacted. The installer cannot reach rubygems, and I get a failures like this:

** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one
Seems that whatever is connecting to rubygems is not respecting the https proxy environment variable passed to docker, hence I am getting the:
Errno::EHOSTUNREACH: Failed to open TCP connection to rubygems .org:443 (No route to host - connect(2) for “rubygems .org” port 443)
Any ideas how I can progress this?
BTW for anyone considering installing behind a proxy, think long and hard - it’s gruelling
