Deploying Hono onto ioFog

You will need to start by setting up and preparing your Kubernetes cluster with an ioFog control plane. Instructions for doing so can be found here.

Assuming you have an ioFog ECN up and running, you need to:

1. Deploy Hono to Kubernetes using Helm
2. Generate an ioFog Microservice YAML spec for Hono deployment
3. Deploy Hono HTTP Adapter to ioFog

Install Hono to your Kubernetes cluster using Helm Chart

Please make sure that you meet the prerequisites for installing Hono's Helm chart.

Then install the chart using hono as the release name. Make sure to replace my-ns with the name of the ioFog name space you are using for your ECN.

kubectl create namespace my-ns
helm install --dependency-update -n my-ns --set adapters.externalAdaptersEnabled=true hono eclipse-iot/hono

Generate ioFog Microservice YAML for HONO HTTP Adapter

The register.sh script can be used to automate the generation of your ioFog application installation file and the configuration files required by Hono's HTTP adapter running on the agent. Make sure to replace the my-ns argument with the name of the name space that you have used for your ioFog ECN and into which you have installed Hono in your Kubernetes cluster.

mkdir /tmp/hono-config
./register.sh my-ns my-agent /tmp/hono-config /tmp/hono-config /etc/hono
cat /tmp/hono-http-adapter.yaml

Deploy Hono HTTP Adapter to ioFog Agent

If you have not installed iofogctl you can find installation instructions here.

Again, make sure to replace the my-ns parameter value with the name of the name space that you have used for your ioFog ECN.

iofogctl deploy -f /tmp/application.yaml -n my-ns
