Configure a cluster
First follow the Dkron clustering guide then you can continue with this guide.
The embedded store also needs to know its peers, it needs its own configuration as in the following example:
# etcd.conf.yaml # Initial cluster configuration for bootstrapping. initial-cluster: dkron1=https://10.19.3.9:2380,dkron2=https://10.19.4.64:2380,dkron3=https://10.19.7.215:2380
With this configuration Dkron Pro should start in cluster mode with embedded storage.
For a more in detail guide of clustering with etcd follow this guide: https://github.com/etcd-io/etcd/blob/master/Documentation/op-guide/clustering.md
