onechart/website/docs/examples/environment-variables.md

OneChart settings for setting environment variables:

image:
  repository: nginx
  tag: 1.19.3

vars:
  VAR_1: "value 1"
  VAR_2: "value 2"

Check the Kubernetes manifest:

cat << EOF > values.yaml
image:
  repository: nginx
  tag: 1.19.3


EOF

helm template my-release onechart/onechart -f values.yaml

!!! note

OneChart creates a `ConfigMap` with all the defined environment variables.

Then includes all entries with the `EnvFrom` field in the deployment.
