Have you worked with Kubernetes? What deployment tools did you use?

Yes, I have worked with Kubernetes. For deployment, I used several tools:

• kubectl — the standard CLI for managing Kubernetes clusters, used YAML manifests to create and update resources.
• Helm — a package manager for Kubernetes that allows creating, versioning, and deploying applications as charts, simplifying management of complex configurations.
• Argo CD — a GitOps tool that automatically synchronizes the cluster state with the Git repository, providing declarative deployment and rollback.

An example of a simple Helm chart for deploying an application:

# Chart.yaml
apiVersion: v2
name: myapp
version: 0.1.0

# values.yaml
replicaCount: 2
image:
  repository: myapp
  tag: latest

# templates/deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Chart.Name }}
spec:
  replicas: {{ .Values.replicaCount }}
  selector:
    matchLabels:
      app: {{ .Chart.Name }}
  template:
    metadata:
      labels:
        app: {{ .Chart.Name }}
    spec:
      containers:
      - name: {{ .Chart.Name }}
        image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"
