values.yaml

icm:

    image:
      repository: "${ICM_TEST_IMAGE}"

environment.sh

#!/usr/bin/env bash
ICM_TEST_IMAGE="whatever"

After executing source ./environment.sh and helm subenv -f values.yaml the env variable is replaced with an empty string.

My base image for execution is ubuntu-20.4-DS1_v2-adopt-adoptium-jdk with the following RUN cmd to install helm:

RUN apk add --no-cache ca-certificates bash git openssh curl \
    && wget -q https://storage.googleapis.com/kubernetes-release/release/${KUBE_LATEST_VERSION}/bin/linux/amd64/kubectl -O /usr/local/bin/kubectl \
    && chmod +x /usr/local/bin/kubectl \
    && wget -q https://get.helm.sh/helm-${HELM_VERSION}-linux-amd64.tar.gz -O - | tar -xzO linux-amd64/helm > /usr/local/bin/helm \
    && chmod +x /usr/local/bin/helm

Hello !

When trying to use bash env variable define in a .env:

.env

variables0="cool"
variables1=("components3" "components3" "components3" ) 
variables2="notcool"

After reference this value in a values.yaml and using the command to make substitution :

helm subenv -f $ENV/$components/values.yaml

I got the following error when the plugin try to substitute the last vars from my file to a values.yaml

To make this work i need to define the variable in this order

.env

variables0="cool"
variables2="notcool"
variables1=("components3" "components3" "components3" ) 

When i want to define a new variable i need to be aware about this comportement, so for new user joining my project it can be difficult if this error appear.

Is it possible to take in count this type of variable from bash ?

Thanks

environment variables in multiple values should be substituted with just one command.
