v0.21.10

Compare Source

v0.21.10 - 2026-09-30

Added

• Add opt-in engine CPU and memory telemetry from cgroup v2 by @​matipan in #​14285
  Enable telemetry.resourceMetrics in /etc/dagger/engine.json and set
  OTEL_EXPORTER_OTLP_METRICS_ENDPOINT in the engine environment. The new
  resource metrics use a separate OTLP export path. Client telemetry is
  unchanged, and engine resource telemetry is disabled by default.

Fixed

• Container.withServiceBinding now works for a service whose custom hostname by @​Zaba505 in #​13751
  was scoped to another module's DNS domain. A service created with
  withHostname is namespaced into the domain of whichever module first starts
  it, so a module that started its own service before handing it to a caller
  left that caller's withExec failing at hosts-file setup with
  lookup <hostname> ... no such host. Binding the service explicitly now
  resolves it by the name it actually registered under. Reaching a module's
  custom hostname by bare DNS remains scoped to that module.
• dag.CurrentModule().Source() and dag.CurrentModule().GeneratedContextDirectory() by @​marcosnils in https://github.com/dagger/dagger/pull/
  no longer re-resolve the running module's declared dependencies. The module's
  already-loaded dependency DAG is reused for codegen, so these APIs now work in
  modules whose dependencies point at private git repositories even when the
  runtime caller does not hold the author's credentials.
