ElixirK8sLambda

The grand idea of us was to create a Kubernetes controller to dispacth and scheduler Elixir Jobs. With the limited time and K8S knowledge we had, we manage to create a controller than when you add resource, it will run the Elixir code that is given in the YAML/JSON file.

Tools

• Minikube
• Kubectl
• Elixir
• Docker or VirtualBox (or other but we haven't tested on them XD)

Build Image

First, run these command to build the Docker Image

eval $(minikube docker-env)

export NOTSURES_IMAGE=elixir-lambda
docker build -t ${NOTSURES_IMAGE} .

Apply the manifest.yaml file

kubectl apply -f ./manifest.yaml

Clean up old deployments if any, example:

kubectl delete elixir-node elixir-kubernetes
kubectl delete job testing
kubectl delete po <pod-name>

Apply elixir-node.json

kubectl apply -f ./elixir-node.json

Check if the job succeeded:

kubectl get po

You will see something like:

NAME                                 READY   STATUS        RESTARTS   AGE
elixir-kubernetes-7b695f5b9d-m7t2q   1/1     Running       0          26s
testing-drfqd                        0/1     Completed     0          3s

You can check the job resuly by calling

kubectl logs -f testing-drfqd
