ciena/onos-form-cluster repository overview

⁠ONOS Form Cluster Docker Image

This contains the files to construct a docker image around the onos-form-cluster utility script. The docker entry point looks for an environment variable (CLUSTER_HOSTS) and waits for each of the ONOS instances specified to respond to their REST interface (http://host:8181/onos/v1/cluster). After all hosts have responded to their REST interface the script then pushes the appropriate cluster configuration to each ONOS instance.

This docker image is meant for usage in a docker-compose file so that the compose can form a cluster after all the ONOS instance are specified.

⁠links

It is important that not only the CLUSTER_HOSTS environment variable is set, but also that each ONOS instance is also linked from this container as well (see docker-compose example below).
