Hey,
We have an OKD setup over multiple DCs. Each DC has its own subnet (e.g.:
172.20.220.0/24 and 172.20.221.0/24). We want each project to have its own ip.
And of course we want the project to be able to still reach other services even
if we lose a DC. Thus what we had in mind was to do the following:
oc new-project test
oc patch hostsubnet node-1.dc1.com -p '{"egressCIDRs": ["172.20.220.0/24"]}'
oc patch hostsubnet node-2.dc2.com -p '{"egressCIDRs": ["172.20.221.0/24"]}'
oc patch netnamespace test -p '{"egressIPs": ["10.231.86.150","10.230.86.150"]}'
With the understanding that the first IP would be assigned to node-1.dc1.com
and the second ip would be assigned to node-2.dc2.com. Thus if we lose a zone
traffic could still go through.
However when we specify multiple IPs none are actually getting assigned. We
found this resolved issue: https://bugzilla.redhat.com/show_bug.cgi?id=1633574
that seems to point that the expected behavior is to not assign any ip.
As I understand it, right now if we want to use automatic Egress IPs we can
only have one IP which is this correct ?
Best
