connectivityserver

This service provides a very simple flask based server to serve connection information to DAQ applications.

Installation

To build the docker image of develop just do 

docker buildx build --tag ghcr.io/dune-daq/connectivityserver:latest .
Or, if you want to specify a tag 
docker buildx build --tag ghcr.io/dune-daq/connectivityserver:v1.3.0 --build-arg VERSION=v1.3.0 .

Apply the kubernetes manifest from connectivityserver.yaml. This should start a service called connectionservice in the namespace connections.

kubectl apply -f connectivityserver.yaml

To test the basic operation of the server, you can connect to pod in the k8s cluster and try getting the root document.

> kubectl exec myPod -i -t -- bash
[root@myPod /]# curl http://connectionservice.connections:5000
