Canonical location for documentation, example workflows and reference service implementations covering distributed execution patterns. Covers AC1-AC4: execution-target selection, decision support, readiness checks and code-level linkage. Tightly coupled jobs and the loosely coupled subprocess transport are verified by the test suite; the Kubernetes pipes transport is implemented but not yet cluster-run and is marked as such in the guide.

# Kubernetes RBAC for the loosely coupled execution target.
|
|
#
|
|
# Granted to the service account running the Dagster RUN pods - the pod that
|
|
# calls PipesK8sClient.run() is the one that creates and watches the payload Job.
|
|
#
|
|
# Note what is NOT here: the payload itself needs no RBAC, no database
|
|
# credentials and no Vault role. Its only channel back to the control plane is
|
|
# the pod log stream, which the dispatching pod reads.
|
|
#
|
|
# If the payload runs in a different namespace from the dispatcher, apply this
|
|
# Role in the PAYLOAD namespace and keep the RoleBinding subject pointing at the
|
|
# dispatcher's service account.
