Argo Workflows 4, What's New And What's Next

on YouTube ↗05m

" summary

Argo Workflows 4.0 adds artifact plugins so custom drivers move data in and out of pods, full CRD validation (no more tiny schemas from 3.7), and removal of plural primitives with an argo convert tool to migrate manifests. The controller gains a restart strategy to restart never-started pods. 4.1 brings workflow tracing with OpenTelemetry links. Roadmap includes a pluggable DAG engine that runs steps as DAGs, pod reuse annotations to cut startup time, and a unified, more debuggable expression engine with syntax changes to avoid Helm conflicts.
