> **Attention**: indentations are important in string parameters.

> **Alternatively install**: using --set instead of --set-string to allow Helm to correctly parse the nested structure:\
$ helm install RELEASE_NAME HELM_CHART_REPO_PATH \

--set global.resources.requests.memory=64Mi \
--set global.resources.requests.cpu=150m \
--set global.resources.limits.memory=256Mi \

--set global.resources.requests.cpu=100m \
--set global.resources.limits.memory=128Mi \

If one resources key is not specified, the value is retrieved from global values (which can be overriden during deployment).
