kubernetes - calico-policy-controller requests etcd2 certificates of a different coreos server
i have two coreos stable servers,
each one includes an etcd2 server and they share the same discovery url.
each generated a different certificate for each of the etcd2 daemons. i installed kubernetes controller on one, (coreos-2.tux-in.com) and a worker on coreos-3.tux-in.com. calico is configured to use the etcd2 certificates for coreos-2.tux-in.com,
but it seems that kuberenetes started the calico-policy-controller on coreos-3.tux-in.com so it can't find the etcd2 certificates. coreos-2.tux-in.com certificates file names start with etcd1 and coreos-3.tux-in.com certificates start with etcd2.
so.. do i just place certificates for both etcd2 daemons on both coreos servers? do I need to restrict kube-policy-controller to start on coreos-2.tux-in.com? what do i do here?
this is my /srv/kubernetes/manifests/calico.yaml file.
cassandra - Cassandra で ETCD を使用できますか?
一部のデータを Key/Value 形式で保存したいと考えています。可用性が高く、より高速なソリューションを探しています。ETCD が分散型の信頼できるキー値ストアであることは知っています。私が把握できないのは、主な目的がデータの保存のみである場合に、ETCD または Cassandra を使用する必要があるかどうかです。
