Documentation for version: v0.1.0
Flotta can run on top of any Kubernetes distributions, for testing and development you can follow this guide to get started running flotta on your devices.
Let’s start with minikube
---> minikube start
😄 minikube v1.22.0 on Fedora 35
🎉 minikube 1.25.2 is available! Download it: https://github.com/kubernetes/minikube/releases/tag/v1.25.2
💡 To disable this notice, run: 'minikube config set WantUpdateNotification false'
✨ Automatically selected the docker driver
👍 Starting control plane node minikube in cluster minikube
🚜 Pulling base image ...
🔥 Creating docker container (CPUs=2, Memory=3900MB) ...
🧯 Docker is nearly out of disk space, which may cause deployments to fail! (95% of capacity)
💡 Suggestion:
Try one or more of the following to free up space on the device:
1. Run "docker system prune" to remove unused Docker data (optionally with "-a")
2. Increase the storage allocated to Docker for Desktop by clicking on:
Docker icon > Preferences > Resources > Disk Image Size
3. Run "minikube ssh -- docker system prune" if using the Docker container runtime

🏄 Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default
Check minikube status:

Flotta operator has a few tools that helps to install flotta, for that, let’s clone it:
git clone https://github.com/project-flotta/flotta-operator -b v0.1.0 --depth 1
cd flotta-operator
First, we need to install Openshift-router, the ingress that it’s supported now:
---> make install-router
kubectl apply -f https://raw.githubusercontent.com/openshift/router/master/deploy/router_rbac.yaml
clusterrole.rbac.authorization.k8s.io/openshift-ingress-router created
clusterrolebinding.rbac.authorization.k8s.io/openshift-ingress-router created
clusterrolebinding.rbac.authorization.k8s.io/openshift-ingress-router-auth-delegator created
namespace/openshift-ingress created
serviceaccount/ingress-router created
kubectl apply -f https://raw.githubusercontent.com/openshift/router/master/deploy/route_crd.yaml
customresourcedefinition.apiextensions.k8s.io/routes.route.openshift.io created
kubectl apply -f https://raw.githubusercontent.com/openshift/router/master/deploy/router.yaml
deployment.apps/ingress-router created
kubectl wait --for=condition=Ready pods --all -n openshift-ingress --timeout=60s
pod/ingress-router-5b9b477c98-gx5pl condition met
Now let’s install Flotta on the cluster:
make deploy IMG=quay.io/project-flotta/flotta-operator:v0.1.0 TARGET=k8s
A bunch of CRDs are now created, where the definitions can be found here:
---> kubectl api-resources | grep flotta
edgeconfigs management.project-flotta.io/v1alpha1 true EdgeConfig
edgedevices management.project-flotta.io/v1alpha1 true EdgeDevice
edgedevicesets management.project-flotta.io/v1alpha1 true EdgeDeviceSet
edgedevicesignedrequest edsr management.project-flotta.io/v1alpha1 true EdgeDeviceSignedRequest
edgeworkloads management.project-flotta.io/v1alpha1 true EdgeWorkload
playbookexecutions management.project-flotta.io/v1alpha1 true PlaybookExecution
--->
At the same time, in the flotta namespace an operator should be running:
---> kubectl -n flotta get pods
NAME READY STATUS RESTARTS AGE
flotta-operator-controller-manager-5ffc74fd8c-wv9cm 2/2 Running 0 2m1s
--->
Flotta is now running and ready to register edgedevices. To register a
edgedevice we need first to retrieve the install scripts using the Makefile
target agent-install-scripts.
make agent-install-scripts
Now, two scripts are created:
Minikube is a local virtual machine, so $ minikube ip cannot be reached from
your edgedevice, for sharing the flotta API port to the edgedevice the best way
is to use kubectl port-forward:
$ kubectl port-forward service/flotta-operator-controller-manager -n flotta 8043 --address 0.0.0.0
On the device, with Fedora already installed, we need to execute the following:
$ sudo hack/install-agent-dnf.sh -i 192.168.2.10
Where 192.168.2.10 is your host ip.
After a while, if you list the devices in your cluster, you can see that the edgedevice is already registered:
---> kubectl get edgedevices
NAME AGE
camera-ny 118s
From here, you should be able to deploy workloads to these devices. As explained here
