Kicking the tires on the policy server

cf auth network-admin network-admin

# list policies
cf curl /networking/v0/external/policies

# create a new policy
cf curl -X POST /networking/v0/external/policies -d '{ "policies": [ {"source": { "id": "some-app-guid" }, "destination": { "id": "some-other-app-guid", "protocol": "tcp", "port": 8080 } } ] }'

# delete that policy
cf curl -X DELETE /networking/v0/external/policies -d '{ "policies": [ {"source": { "id": "some-app-guid" }, "destination": { "id": "some-other-app-guid", "protocol": "tcp", "port": 8080 } } ] }'

Using your own CNI plugin

1. Remove the following BOSH jobs:

• cni-flannel
• netman-agent

1. Remove the following BOSH packages:

• flannel
• flannel-watchdog
• netman-agent

1. Add in all packages and jobs required by your CNI plugin. At a minimum, you must provide a CNI binary program and a CNI config file.

• For more info on bosh packaging scripts read this.
• For more info on bosh jobs read this.

1. Update the deployment manifest properties

garden-cni:
  adapter:
    cni_plugin_dir: /var/vcap/packages/YOUR_PACKAGE/bin # your CNI binary goes in this directory
    cni_config_dir: /var/vcap/jobs/YOUR_JOB/config/cni  # your CNI config file goes in this directory

Remove any lingering references to flannel or cni-flannel in the deployment manifest.
