I don't know if this is the best place to ask this question but I wanted to know if someone could help me understand this config file for Redis inside a node. I understand some of it but wanted to get a full understanding of what the config file is doing, in particular, each of the spec sections.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      component: redis
  template:
    metadata:
      labels:
        component: redis
    spec:
      containers:
        - name: redis
          image: redis
          ports:
            - containerPort: 6379
