magnum create k8s cluster success but can't access dashboard

[Chiawei Xie]

I follow this documentation to install magnum in OpenStack ocata.
https://docs.openstack.org/project-install-guide/container-infrastructure-management/ocata/install-ubuntu.html

I create k8s cluster success, and use "kubectl -n kube-system get pod" command,
this is output.

NAME READY STATUS RESTARTS AGE
kube-controller-manager-192.168.0.7 1/1 Running 0 23h
kube-proxy-192.168.0.7 1/1 Running 0 23h
kube-proxy-k8-avkls3iuyj-0-vm6imx37ihe5-kube-minion-7yoe5onyp7ef 1/1 Running 0 23h
kube-scheduler-192.168.0.7 1/1 Running 0 23h
kube-ui-v4-69ls1 1/1 Running 0 23h

we can see kube-ui not kube-dashboard.
I found this blueprint (Add kube dashboard and remove kube ui) https://review.openstack.org/#/c/441046/
But in Ocata don't have this change.

So I follow this change to update code ,and create cluster again.
But cluster create failed, I check magnum-conductor log , It has ERROR message(In attachment)
Does anybody know How can I do?

You picket also the change to add docker_volume_type. That is the reason the conductor fails.

You have two options:
Option 1: Revert the code to ocata without the cherry-picked change and then create the kubernetes dashboard manually. You can either take the manifests from here [1] or here [2].

Option 2: To fix you modified ocata version you could remove these lines [3][4] and add default: "" in [5].

Closing as invalid, the reporter modified the stable branch unsuccessfully. Ocata is working properly.

@dommgifer Feel free to ask more questions on #openstack-containers on Freenode or the OpenStack ML using [magnum] in the subject.
