Environment variables

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

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