Bugfix backport: sysctl.conf vrouter namespace
Upstream bug report [1], proposed change backported from [2].
Temporary backport proposed fix until fuel-library merges it.
Currently net.ipv4.ip_nonlocal_bind is not set inside vrouter
namespace.
This can lead to deployment failure with p_dns error:
ocf-ns_dns: INFO: dnsmasq daemon is not running
ocf-ns_dns: ERROR: dnsmasq: failed to create listening socket for
10.109.5.1: Cannot assign requested address
ocf-ns_dns: ERROR: Error. dnsmasq daemon returned error 0.
We had very similar issue in the past:
https://bugs.launchpad.net/fuel/+bug/1500871
We need to add
ocf_run $RUN_IN_NS /sbin/sysctl -w net.ipv4.ip_nonlocal_bind=1
To get_ns() in ns_dns and ns_vrouter
