# Alpine Linux doesn't use pam, which means that there is no /etc/nsswitch.conf,
# but Go and CGO rely on /etc/nsswitch.conf to check the order of DNS resolving.
# To fix this we just create /etc/nsswitch.conf and add the following line:
#RUN echo 'hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4' >> /etc/nsswitch.conf
