Setting separate values for environment variable in HELM for DEV, PRESTAGING, STAGING and PROD
I am currently using Helm charts for deployment.
What I basically wanted to do is to set environment variables for different environments.
Use-case:
I am using Helm to deploy a Node JS application and based on the value of the environment variable NODE_ENV which will be set while deployment I wish to load specific config files.
Example:
env:
- name: NODE_ENV
value: production
...
I was going through HELM charts and I am unable to join the dots as to how we can use the templates/deployment.yaml, values.yaml and a deployment.yaml to establish the same.
Note:
It is the same environment variable which will hold separate values based on the deployment environment.
Any help would be helpful.

You can use templating to set the value of the environment variable:
- name: NODE_ENV
value: {{ .Values.env | quote }}
Your chart's values.yaml file should provide a default value:
env: production
When you actually go to deploy the chart, you can provide an additional YAML file of values (or more than one)
helm install --name my-chart ./charts/my-chart -f values.dev.yaml
And then that YAML file can provide values that override the chart's default
env: development
