Re: [openstack-dev] [Magnum] Question of k8s multiple master support.
Hi Yatin, fengbeihong, I'm using CoreOS to create Kubernetes CoreOS cluster. Thank you so much.

Re: [openstack-dev] [Magnum] Question of k8s multiple master support.
Hi atsumi, Multiple masters must be created together with load balancer. Create cluster template with `--master-lb-enabled`. magnum cluster-template-create --name k8s-cluster-template --image-id test.qcow2 \ --keypair-id testkey \ --external-network-id public \ --dns-nameserver 8.8.8.8 \ --flavor-id m1.medium \ --coe k8s \ --master-lb-enabled And specify master count when you create cluster. magnum cluster-create --name dcos-cluster --cluster-template dcos-cluster-template --node-count 1 --master-count 3 Best regards, fengbeihong 2016-11-22 10:10 GMT+08:00 渥美 慶彦 : > Hi all, > > Can I create the bay of Kubernetes which has multiple master? > I'm able to create the bay of Kubernetes single master, but failed in > creating the bay of Kubernetes multiple master. > I'm using CoreOS-1010.3.0, Magnum 2.0.1. > > Best regards, > > -- > > Yoshihiko Atsumi > atsumi.yoshih...@po.ntts.co.jp > > > > > __ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev > __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
