You need docker desktop installed on your host to run the quickstart: https://docs.docker.com/desktop

Minikube

You also Minikube on your host.

If you are on Linux follow instructions for ArchLinux (also tested with Fedora): https://dev.to/xs/kubernetes-minikube-with-qemu-kvm-on-arch-312a

Minikube installation in Mac/Windows https://minikube.sigs.k8s.io/docs/start/

argocd CLI

Install argocd cli:

$ brew install argocd

kubectl CLI

Install kubectl:

$ brew install kubectl

helm

Install helm:

$ brew install kubernetes-helm
$ helm init

Start Minikube

Set docker driver and reserve 16GB RAM and 4 CPUs to Minikube:

$ minikube delete
$ minikube config set driver docker

$ touch /tmp/config && export KUBECONFIG=/tmp/config
$ minikube start --memory 16384 --cpus 4

Install ArgoCD Server in Minikube

Install ArgoCD on argocd namespace and expose it on port 8080:

$ kubectl create namespace argocd
$ kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

When state is Running, expose on port 8080:

$ kubectl port-forward svc/argocd-server -n argocd 8080:443

Install CFK in Minikube

Create a namespace named confluent:

$ kubectl create namespace confluent
$ kubectl config set-context --current --namespace confluent

Add confluent repository to helm:

$ helm repo add confluentinc https://packages.confluent.io/helm
$ helm repo update

Install confluent-for-kubernetes operator (latest version) from Confluent’s Helm repo:

$ helm upgrade --install confluent-operator confluentinc/confluent-for-kubernetes --set kRaftEnabled=true

Deploy CP Platform using ArgoCD

Obtain Password to login to ArgoCD:

$ kubectl get secret -n argocd argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

Login to ArgoCD:

argocd login localhost:8080 --username admin --password <your-password>

Deploy cp-platform-app on confluent namespace for dev environment:

argocd app create cp-platform-app \
--repo https://github.com/ncapelle/cfk-deployment.git \
--path confluent-platform/environments/dev \
--dest-server https://kubernetes.default.svc \
--dest-namespace confluent \
--sync-policy automated

Apply changes on resources using ArgoCD

Obtain Password to login to ArgoCD:

$ kubectl get secret -n argocd argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

Login to ArgoCD:

$ argocd login localhost:8080 --username admin --password <your-password>

Apply configuration-app on confluent namespace for dev environment:

$ argocd app create configuration-app \
--repo https://github.com/ncapelle/cfk-deployment.git \
--path configuration/environments/dev \
--dest-server https://kubernetes.default.svc \
--dest-namespace confluent \
--sync-policy automated

Teardown

$ minikube delete
