In the part Charts and Versioning of Helm documentation, the release name of a chart is recommend to defied as `${chart_name}-${chart_version}`, then we use `helm install --name ${release_name}` to install the chart. When the code base of chart version is changed to ${chart_version_2}, we need to upgrade the chart with helm CLI `helm upgrade [RELEASE]`. In order to upgrade the chart, we need to use release name `${chart_name}-${chart_version}`, but it changes to the new release name `${chart_name}-${chart_version_2}`, which will result in another release installation.
