OpenFlow was designed to run on kubernetes. You can still deployed in other ways, but for most production setups, that is the recommend platform to run it on, at least for the primary site.
We use helm to deploy different deployments to kubernetes, so first install helm simply drop this some where and add it to the path, so you can reference it from cmd/powershell. Also, make sure you have kubectl installed and configured to access your kubernetes cluster.
OpenFlow depends on traefik as ingress controller. It’s beyond the scope of this guide on how to install this in non-clouded envoriments, but if you are using GKE, aWS, Azure, Alibaba or some of the other cloud providers that has out of the box external loadbalencers, you can simpy deploy trafik with the service with type: LoadBalancer, and from here on everything “just works”.
You can find an example on how to deploy traefik using help on this page
So first we need to add OpenIAP’s helm repo and update this and other repos you might have installed
helm repo add openiap https://open-rpa.github.io/helm-charts/ helm repo update
Next create a values file. To avoid confusen i recomend you name this file the same as your namespace and the “instance” you are creating. So imaging you want to deploy an openflow instance responding to demo.mydomain.com then create a file named demo.yaml
There is a ton of different settings you can fine tune, you can always find all the settings in the openflow values file here but you only need to add the values you want to override. So as a good starting point, add the following to your demo.yaml file
# this will be the root domain name hence your openflow url will now be http://demo.mydomain.com domainsuffix: mydomain.com # this will be added to all domain names domain: demo # if using a reverse procy that add ssl, uncomment below line. # protocol: https openflow: # external_mongodb_url: mongodb+srv://user:email@example.com?retryWrites=true&w=majority rabbitmq: default_pass: supersecret # if you are using mpongodb atlas, or has mongodb running somewhere else # uncomment below line, and external_mongodb_url in openflow above # mongodb: # enabled: false
So first we need to create a namespace. Namespaces allow us to segregate multiple installations from each other, and ensure they run completely independently of each other.
kubectl create namespace demo
and now we can create our first openflow installation inside that namespace
helm install openflow openiap/openflow -n demo --values ./demo.yaml
If you update the demo.yaml values file, you can update the installation with
helm upgrade openflow openiap/openflow -n demo --values ./demo.yaml
