DataFlow Sealos Packaging

This directory contains the Sealos cluster-image packaging for DataFlow.

Layout

Kubefile: cluster image build recipe
install.sh: install entrypoint executed by the cluster image
charts/dataflow/dataflow-values.yaml: default user override template
charts/dataflow: Helm chart used by the installer

CI Flows

PR workflow: .github/workflows/pr-docker-build.yml
- builds runtime images on both amd64 and arm64
- pushes it into a temporary local registry
- runs sealos registry save
- exports Sealos image tar artifacts for both architectures
Release workflow: .github/workflows/release.yaml
- publishes multi-arch runtime images
- packages multi-arch Sealos cluster images
- publishes release tarballs for version tags

Local Packaging Flow

Build and push a runtime image that the chart references.
Update charts/dataflow/values.yaml with that image repository and tag.
Run sealos registry save --registry-dir=registry_<arch> --arch <arch> . in deploy/.
Build Kubefile to produce the final cluster image.

User Overrides

During install, install.sh ensures the user override file exists at:

/root/.sealos/cloud/values/apps/dataflow/dataflow-values.yaml

When the file does not exist yet, it is initialized from:

deploy/charts/dataflow/dataflow-values.yaml
