[DOCS] Port map for firewalls
Last modified: 2017-09-20 01:43:47 EDT
There should be a section in administration guide to let the users know which ports should be open between the openshift environment if there is a firewall between broker and nodes
Say : master to node
node to node
master to master
external to master
A ports doc is now in the OSE 3.0 docs:
*** Bug 1280411 has been marked as a duplicate of this bug. ***
Can we make protocols more visible? I think it would be better to have TCP/80 UDP/4789 rather than notes at the end of the page.
Also a question stands for port 53 - is it supposed to be both TCP and UDP? When I check my master I see that both TCP/53 and UDP/53 are being listened to.
# lsof -i | grep domain
openshift 952 root 40u IPv4 18625 0t0 TCP *:domain (LISTEN)
openshift 952 root 41u IPv4 18627 0t0 UDP *:domain
See comment in https://github.com/openshift/openshift-docs/pull/1136#issuecomment-161337791 for latest.
The table is published in the 3.1 docs, but I'm moving this BZ back to ASSIGNED while I work on getting it into the 3.0 branch correctly (see above GH comment for details). I'll also address Evgheni's protocol suggestion (for both 3.0 and 3.1).
Feedback from ccs list:
"These tables in the 'required ports' section don't specify protocol, could you please add a column containing tcp/udp"
@Brice - this is quite old and I am happy for you to close it if there is no more work to be done on this.
