Is it possible to include an environment in a Helm package?

In Helm charts, environment variables can be included and used in templates to configure deployment.

Typically, environment settings are defined through values in values.yaml or via command-line parameters during chart installation (helm install --set). In templates, these values are used to substitute into Kubernetes manifests, for example, in the env section of containers.

Example in a Deployment template:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Release.Name }}
spec:
  template:
    spec:
      containers:
      - name: app
        image: myapp:{{ .Values.image.tag }}
        env:
        - name: ENVIRONMENT
          value: "{{ .Values.environment }}"

In values.yaml, define:

environment: production

Thus, environment settings are passed into templates via parameters, allowing flexible configuration at deployment time.
