Run Pullpiri (a.k.a. Piccolo) examples

This document is for LG's internal reference and will be updated separately under the doc folder for external (official) use.

Preparation

Basically, there is Piccolo-related documents in doc/docs folder, but there are many parts that are different from the present as past data, so it is only used for reference.

You need to install Podman with container runtime. You can also use Docker (but NOT recommend).

It is STRONGLY recommended to install etcdctl for low-level verification. Download link

Download appropriate tar.gz and untar file, you can see etcdctl binary. If you put this binary in a PATH like /usr/bin, you can use it without installing anything.

Optional : CentOS stream (or RHEL) + Eclipse Bluechi (Maybe you will need it later)

Make container image & Run Piccolo

Refer Getting started for launching Piccolo. All you have to do is run make install and you're ready to go.

Check logs of containers

# [root@HPC Pullpiri]# podman logs piccolo-server-apiserver 
http api listening on 0.0.0.0:47099
# [root@HPC Pullpiri]# podman logs piccolo-player-filtergateway 
FilterGatewayManager init
Piccolod gateway listening on 0.0.0.0:47002
FilterGatewayManager successfully initialized
# [root@HPC Pullpiri]# podman logs piccolo-player-actioncontroller 
Starting ActionController...
Starting gRPC server on 0.0.0.0:47001
gRPC server started and listening

Run example

Put Piccolo scenario into apiserver by shell script

In this folder (examples), there is a helloworld.sh script. Replace NODE_NAME in spec:models[0]:node with your bluechi controller node name. (My node is HPC)

......
---
apiVersion: v1
kind: Package
metadata:
  label: null
  name: helloworld
spec:
  pattern:
    - type: plain
  models:
    - name: helloworld
      node: {NODE_NAME}
      resources:
        volume:
        network:
---
......

When you run this, you call the PUT method with the apiserver's HTTP API.

./helloworld.sh

Check logs

You can see helloworld container (is restart infinitly.)
