i wanted to test Longhorn on Ubuntu 16.04 but i ended up with this:
clean up longhorn-etcd-server if exists
Unable to find image 'quay.io/coreos/etcd:v3.1.5' locally
docker: Error response from daemon: Get https://quay.io/v1/_ping: x509: certificate signed by unknown authority.
Example is not working.
Also im wondering if longhorn is stable/production ready with cattle environments ?
