# M/N Upgrade only: By default RHEL/Centos has an /etc/sysconfig/iptables file which
|
|
# allows ssh and icmp only (INPUT table). During the install of OSP9/Mitaka
|
|
# usually the live iptables rules are not the ones in /etc/sysconfig/iptables but
|
|
# they are completely open (ACCEPT)
|
|
# Now when we run the convergence step while migrating to Newton we enable the firewall
|
|
# by default and this will actually first load the rules from /etc/sysconfig/iptables
|
|
# and only afterwards, it will start adding all the rules permitting openstack traffic.
|
|
# This causes an outage of roughly 1 minute in our env, which disrupts the cluster.
|

# Let's simply move the existing file out of the way, it will be recreated by
|
|
# puppet in newton with the proper firewall rules anyway
