Republish an old OCI-based chart using Helm 3.7+

helm_oci_chart_overwrite.sh

# Temporarily install older version of Helm (3.6.3), enable OCI support
mkdir -p tmp/
curl https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | \
  DESIRED_VERSION="v3.6.3" USE_SUDO="false" HELM_INSTALL_DIR="${PWD}/tmp" bash
mv tmp/helm tmp/helm36
export PATH="${PWD}/tmp:${PATH}"
export HELM_EXPERIMENTAL_OCI=1

# Configure settings for old OCI chart
OCI_ROOT="bundle.bar/u/jdolitsky/demo/bitnami"
CHART_NAME="wordpress"
CHART_VERSION="10.0.6"

# Download and extract old version of OCI chart using old version of Helm
helm36 chart pull "${OCI_ROOT}/${CHART_NAME}:${CHART_VERSION}"
helm36 chart export "${OCI_ROOT}/${CHART_NAME}:${CHART_VERSION}"

# Package and push new OCI chart using Helm 3.7+
helm package "${CHART_NAME}/"
helm push "${CHART_NAME}-${CHART_VERSION}.tgz" "oci://${OCI_ROOT}"

Once above script is run, is it replacing the chart of the same name and tag (and digest), or add a new entry?

If replacement, after the run, helm36 chart pull "${OCI_ROOT}/${CHART_NAME}:${CHART_VERSION}" would fail, correct?

@dancnfoo - it should be complete replacement.

I'm not sure if helm36 chart pull would fail or not... in any case it it not recommended. Let me what results you have if you try
