Flux not honouring /etc/hosts file

[rampreethethiraj]

We have a private repo where we store all the images. When flux is trying to read images from this private repo, what is happening is that it is resolving the dns to a public ip and is trying to connect there despite specifying hostAliases in the yaml and I have crossverified that under /etc/hosts there is an entry for the docker repo. Could someone please help me out as to understand what is happening here .

This is most likely connected to golang/go#22846: Go's native hostname resolution checks DNS before /etc/hosts (in the absence of /etc/nsswitch.conf). We use alpine as the base image, and there is no /etc/nsswitch.conf shipped with alpine.

Remedy: we can include a minimal /etc/nsswitch.conf in the image, as suggested in the issue mentioned.
