Hi Dave, 'oc cluster up' is not meant to be used to run a multi-node cluster. It will only stand up a single-node cluster. The main issue is networking. It won't setup an sdn for you. However, you can make it listen on an alternate address by specifying a numeric IP address with --public-hostname
The oc cluster join command is an experimental command meant to add a node to an existing cluster that was setup via ansible. Despite the common command prefix, it has no relation to 'oc cluster up'. To install openshift on 2 nodes, please use the openshift-ansible installer. You'd need to setup ansible in a client machine and create an inventory file that points to your 2 machines. You can find a sample inventory and instructions here: https://docs.openshift.org/3.9/install_config/install/advanced_install.html#single-master On Wed, Apr 18, 2018 at 6:20 PM, Dave Neary <[email protected]> wrote: > Hi all, > > I am trying to set up a small 2 node OpenShift cluster on two NUCs (each > with 16G of RAM and 120GB SSDs), and I've hit a snag. > > It looked like oc cluster up/oc cluster join would be the easiest way to > do it without setting up independent VMs and using minishift, so that is > what I'm trying. > > I'm following the instructions here: > https://wiki.centos.org/SpecialInterestGroup/PaaS/OpenShift-Quickstart > > My issues: > > * On master: oc cluster up is listening on 127.0.0.1 rather than an > externally accessible IP address - oc cluster --help doesn't give any > clue as to how to set the IP address for the server to listen on > * On node: oc cluster join wants a secret from the master - an internet > search tells me that I can get that by copying and pasting the value of > admin/kubeconfig - but I have no idea where to find that. > > Anyone know how to change the IP the server listens on, and add one > other node to make a 2 node cluster?
