In some envrionemtns fails with getaddrinfo ENOTFOUND localhost #31

Closed kevincox closed 3 years ago

kevincox commented 3 years ago

Sorry for the weird issue, but I don't really know where to start debugging. My build fails on GitLab (no sandboxing) with a really strange error. Builds on my laptop NixOS (with or without sandboxing) are fine. Building on my laptop using the local GitLab runner does fail.

There is a localhost entry in the hosts file for both IPv4 and IPv6.

$ cat /etc/hosts

This seems to be stemming from the custom image that the build runs in but I haven't been able to identify the cause yet. https://gitlab.com/kevincox/nix-ci/-/blob/v1/default.nix

I'm opening this bug to help anyone else seeing a similar problem and ideally collect debugging tips and information. Feel free to close if you consider it off-topic.

One other question: Do you think it would be possible to use a loopback IP directly instead of localhost? It would remove a dependency in the stack even if I should get a proper environment set up.

I found the issue. I needed an /etc/nsswitch.conf. Without it node was going directly to the DNS server.

Still worth considering using an IP instead of a hostname, but my issue is resolved.
