armaan | strigazi: hello, Is there a need to open a port other than 9511 for magnum to work? | 10:35 |
*** pbourke has quit IRC | 10:46 | |
strigazi | armaan: You can use magnum in another port by changing the port in magnum.conf and updating the endpoints accordingly | 10:47 |
*** pbourke has joined #openstack-containers | 10:48 | |
armaan | strigazi: I have opened the port 9511 already and magnum api from outside world is working fine. I was wondering if internally any service tries to access any other port like 9090? | 10:49 |
armaan | which also needs to be opened in the firewall. | 10:49 |
strigazi | you don't have to open to the outside of your cloud | 10:50 |
strigazi | the magnum api must be reachable from the vm in your cloud | 10:50 |
strigazi | not from outsie | 10:50 |
strigazi | not from outside | 10:50 |
armaan | strigazi: Please correct me if i am wrong, my assumption is that the VM running in the compute node should only be able to access 9511 on the controllers? and no other port? | 10:51 |
strigazi | The vms also need to be able to contact: nova (for the kube-openstack cloud provider), keystone (tokens), heat (signal heat and software deployments), cinder ( if you want to use volumes) and neutron (for lbaas) | 10:52 |
armaan | strigazi: If a customer makes an api call to create a cluster, i suppose that will go to port 9511 and we need to open port 9511 to the world? | 10:52 |
*** belmoreira has joined #openstack-containers | 10:52 | |
armaan | strigazi: ok, yes i have made sure that VM can access all those endpoints. | 10:53 |
strigazi | armaan oh ok, you mean for users | 10:53 |
armaan | strigazi: yes, we run a public cloud. | 10:53 |
strigazi | armaan: yes, for users to contact magnum you need 9511 *only* | 10:53 |
armaan | so customer need to issue api calls against port 9511 | 10:54 |
armaan | okay. | 10:54 |
armaan | strigazi: Do you have any suggestion on how can i tackle the liveness and dashboard endpoint problem in our Pike setup? If a python developer is needed to tackle it, i think we can allocate one to this issue? | 10:55 |

strigazi | armaan ok, then to eliminate the space issue, remove docker-volume-size | 14:49 |
armaan | strigazi: Do you think this could be behind the liveness issue as well? | 14:52 |
strigazi | armaan I'm now sure, perhaps | 14:53 |
strigazi | armaan: you had one master? | 14:53 |
armaan | strigazi: yes | 14:53 |
serlex | ok thanks ykarel | 14:54 |
serlex | still trying to get to the bottom of "/var/lib/kubelet/plugins/kubernetes.io/cinder/mounts/6a214668-faec-4e6f-98e1-6115ef138300 does not exist" | 14:54 |
armaan | ykarel: IIRC, you were able to get the dashboard endpoints with a single machine deployment? but you had to make some change? | 14:54 |
ykarel | armaan yes | 14:54 |
ykarel | serlex, i faced this but can't remember the fix now | 14:55 |
ykarel | serlex, did you checked kubelet logs on minion node where pod is running? | 14:56 |
serlex | i have and looking at it right now, seems very noisy, trying to identify the relevant failures | 14:58 |
armaan | ykarel: IIRC the change was related to endpoints? | 14:58 |
ykarel | armaan, yes i also remember the same | 14:58 |
ykarel | let me check if i have noted the other changes | 14:59 |
ykarel | i did | 15:00 |
*** vijaykc4 has quit IRC | 15:00 | |
ykarel | yes wc-notify also failed, but after endpoint change it worked | 15:01 |
armaan | ykarel: great, could you please share those | 15:01 |
armaan | oh | 15:01 |
armaan | ykarel: i have this: http://paste.openstack.org/show/658170/ | 15:03 |
armaan | ykarel: IIRC you changed the public endpoints of keystone and magnum? | 15:04 |
ykarel | and heat, nova | 15:05 |
armaan | ykarel: Changed the public endpoints of keystone, magnum, heat and nova from https to http? | 15:07 |
ykarel | armaan, yes | 15:07 |
armaan | ykarel: ok, does that mean that it is a ssl related issue? | 15:08 |
ykarel | armaan, i don't think that | 15:08 |
ykarel | i changed endpoint just to check that if that was dashboard issue | 15:08 |
ykarel | and i saw errors related to ssl in my case, that's why i changed | 15:09 |
serlex | ykarel...could you have a quick glance? https://pastebin.ubuntu.com/26495580/ | 15:09 |
ykarel | armaan, for ex: kube-controller-manager failed due to Error: Jan 21 06:03:10 k8s-cluster-idkrik4qobks-master-0.novalocal runc[4840]: F0121 06:03:10.111442 1 controllermanager.go:176] error building controller context: cloud provider could not be initialized: could not init cloud provider "openstack": Post https://192.168.100.15:5000/v3/auth/tokens: x509: cannot validate certificate for 192.168.100.15 because it doesn't contain any IP | 15:09 |
ykarel | SANs | 15:09 |
serlex | or any other contributor | 15:10 |
ykarel | also cert creation failed, but in you case you haven't seen these errors. right? | 15:10 |
armaan | ykarel: how can i confirm? | 15:10 |
ykarel | armaan, check kube-controller-manager, kubelet logs | 15:10 |
