helm-oci-ecr

Recipe to push both

• docker image
• helm chart

into a single ECR repo, like this:

image:       aws_account_id.dkr.ecr.region.amazonaws.com/miniapi:1.0.6
chart: oci://aws_account_id.dkr.ecr.region.amazonaws.com/miniapi --version 1.1.0

We could also use distinct repo names:

image repo	chart repo	comment
miniapi/image	miniapi	This works, but image repo name is ugly.
miniapi	miniapi-chart	ECR requires the chart name should be miniapi-chart, even uglier.
miniapi	miniapi	Distinct tag spaces are required.

The trick is to use distinct tags.

Notice how karpenter stores image under 0.27.5 while chart lies under v0.27.5.

helm show chart oci://public.ecr.aws/karpenter/karpenter --version v0.27.5 | grep -i version
Pulled: public.ecr.aws/karpenter/karpenter:v0.27.5
