# In the Travis VM-based build environment, IPv6 networking is not
# enabled by default. The sysctl operations below enable IPv6.
# IPv6 is needed by some of the CoreDNS test cases. The VM environment
# is needed to have access to sudo in the test environment. Sudo is
# needed to have docker in the test environment. Docker is needed to
# launch a kubernetes instance in the test environment.
# (Dependencies are fun! :) )
