# Do not forward queries for plain names (no dots)
domain-needed
# Query the upstream servers in the order they appear. This is necessary when
# kubernetes is configured, to ensure we send queries for kubernetes names
# (ending in .cluster.local) to the kubernetes dns server first. In the future,
# we could add the kubernetes dns server using the "server" option, which would
# allow us to force all cluster.local names to go to that server.
strict-order
# Only keep entries in the cache for 5 seconds. This is required because the
# kubernetes dns server will reply to queries for services that do not yet
# exist with an SOA record containing a long TTL, which will result in dns
# queries failing for a very long time, even after the service comes up (e.g.
# after a host is rebooted).
