CN-infra examples

There are several main.go files used as an illustration of the cn-infra functionality. Most of the examples show a very simple use case using the real ETCD and/or Kafka plugins, so for specific examples, they have to be started first.

Current examples:

• etcd uses the ETCD data broker to write data into ETCD, which are then caught by the watcher
• flags example registers flags and shows their runtime values
• kafka creates a simple plugin which registers a Kafka consumer and sends a test notification
• logs shows how to use the logger and wotk wiht log levels

How to run an example

1. Start ETCD server on localhost

sudo docker run -p 2379:2379 --name etcd --rm \
quay.io/coreos/etcd:v3.0.16 /usr/local/bin/etcd \
-advertise-client-urls http://0.0.0.0:2379 \
-listen-client-urls http://0.0.0.0:2379

2. Start Kafka

sudo docker run -p 2181:2181 -p 9092:9092 --name kafka --rm \
 --env ADVERTISED_HOST=172.17.0.1 --env ADVERTISED_PORT=9092 spotify/kafka

3. Start the desired example

Each example can be started now from its directory.

go run main.go  \
--etcdv3-config=/opt/vnf-agent/dev/etcd.conf \
--kafka-config=/opt/vnf-agent/dev/kafka.conf
