Build Fails on New Host

[Samir_Faci]

I copied and the entire /var/discourse to a new host. Updated the CNAME and SSL all working fine. When I try to do a rebuild, I get an issue with that I can’t figure out.

 sudo ./launcher rebuild app

A wget the rubygems works fine, internet connectivity is fine. Any suggestions?

A wget the rubygems works fine, internet connectivity is fine.

If internet connectivity is working on the host, you need to debug internet connectivity inside docker containers on that host.

Can't build container, no clear errors

The real problem is this one: If the server/container can’t access the Discourse source code in GitHub it won’t be able to build/update. Since you said it works on the host, you need to debug the container networking. Drop to a similar container shell with docker run --it debian:buster-slim bash and debug from there.

I found my issue. I have IPv6 enabled on docker which seems to confuse things.

I had to turn it off then reload docker.

{
  "ipv6": false,
  "fixed-cidr-v6": "2001:db8:1::/64"
}

Thank you for the help!

"fixed-cidr-v6": "2001:db8:1::/64"

More specifically: you had IPv6 enabled and configured to hand out addresses that won’t get back to your containers.

Not all apps are written to fall back to v4 of v6 connectivity is broken.
