Add /etc/nsswitch.conf to alpine images

[2solt]

Looks like non of the TICK application using /etc/hosts without it.
Adding the following line to Dockerfile solves the problem:
RUN echo 'hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4' > /etc/nsswitch.conf

[jsternberg]

It looks like the default value for this in the standard ubuntu image is:

hosts: files dns

What are the other sections you've placed in the line?

[2solt]

Yeah your right, that's should be sufficient.
(The other options is for mDNS or Multicast DNS )
