Hi Alejandro, It looks your etcd cluster failed to elect a leader. You might want to check your etcd log for details, and bring your etcd cluster back to healthy state. Unfortunately, I don't have operational experience with etcd. You would need to look at their admin guide for help: https://coreos.com/etcd/docs/latest/v2/admin_guide.html . In the worst case, remove and re-install etcd could work. Best regards, Hongbin On Tue, Apr 30, 2019 at 5:32 PM Alejandro Ruiz Bermejo < arbermejo0417@gmail.com> wrote:
Hi, i'm installing Zun in Openstack Queens with Ubuntu 18.04.1 LTS, i already have configured docker and kuyr-libnetwork. I'm following the guide at https://docs.openstack.org/zun/queens/install/index.html. I followed all the steps of the installation at controller node and everything resulted without problems.
After finished the installation direction at compute node the *systemctl status zun-compute* have the following errors

When i try to launch an app container as the guide says it shows an Error state and when i run opentack appcontainer show this is the reason of the error status_reason | Docker internal error: 500 Server Error: Internal Server Error ("failed to update store for object type *libnetwork.endpointCnt: client: etcd member http://controller:2379 has no leader")
I had some troubles installing Kuryr-libnetwork besides that i didn't had any othet problem during the installation of Zun
