How to re-route the Openshift private address to a

I set up openshift V3 all-in-one on a VM in the cloud so how can I contact it as the address is private and internal. I think I have to start Vagrand with some magic parameters but I haven't clue about them. Thanks

回答1:

When testing Openshift, I deployed the all in one VM in an Openstack instance. To be able to access Openshift, I had to change master-config.yaml configuration (which in the VM is located in /var/lib/origin/openshift.local.config/master/master-config.yaml)

Changing all references of the internal IP (10.2.2.2) to my public domain (https://my-domain.com:8443) did the trick.

I also had to regenerate the server certificates, including the public IP of my Openstack instance, this way:

oadm ca create-server-cert --cert=master.server.crt --key=master.server.key --signer-cert=/var/lib/origin/openshift.local.config/master/ca.crt --signer-key=/var/lib/origin/openshift.local.config/master/ca.key --signer-serial=/var/lib/origin/openshift.local.config/master/ca.serial.txt --hostnames=kubernetes.default.svc,kubernetes.default.svc.cluster.local,localhost,openshift.default.svc.cluster.local,127.0.0.1,10.2.2.2,yourdomain.com,yourpublicIP

Hope this helps

Here is what I've tried (in an answer to better document my attempts)

1 -

systemctl stop origin

2 -

oadm ca create-server-cert --cert=/var/lib/origin/openshift.local.config/master/master.server.crt --key=/var/lib/origin/openshift.local.config/master/master.server.key --signer-cert=/var/lib/origin/openshift.local.config/master/ca.crt --signer-key=/var/lib/origin/openshift.local.config/master/ca.key --signer-serial=/var/lib/origin/openshift.local.config/master/ca.serial.txt --hostnames=kubernetes.default.svc,kubernetes.default.svc.cluster.local,localhost,openshift.default.svc.cluster.local,127.0.0.1,192.168.76.120

3 -

edit /var/lib/origin/openshift.local.config/master/master-config.yaml, replace all occurences of "10.2.2.2" with "192.168.76.120"

4 -

edit /etc/systemd/system/origin.service, replace "10.2.2.2" with "192.168.76.120"

5 -

systemctl daemon-reload

6 -

systemctl start origin

Following these steps, I get the following in the /var/log/messages:
