Google Cloud Run decommissions Go 1.22 and schedules Go 1.23 for 21 August
Google Cloud Run's managed runtime schedule marks Go 1.22 decommissioned from 28 July 2026 and Go 1.23 for decommissioning on 21 August 2026, after which affected managed-base-image workloads cannot be created or redeployed and existing workloads may be disabled.
Previous state
Cloud Run workloads using Google-managed Go 1.22 and Go 1.23 base images remained within their supported or deprecated deployment windows.
Current state
Go 1.22 has entered decommission, and Go 1.23 reaches the same state on 21 August; decommissioned managed runtimes cannot be used for creation or redeployment and receive no runtime, system-package or OS updates.
Affected users
Who needs to care
Cloud Run functions and source-deployed workloads using Google-managed base images for runtime IDs go122 or go123. Directly deployed container images are outside this lifecycle policy.
Required response
What to do
Locate workloads using go122 or go123, upgrade to a supported Go runtime, rebuild and redeploy before the applicable decommission date, and verify that deployment automation and base-image references no longer pin the retired runtime IDs.
Evidence boundary
What the source does not prove
The lifecycle policy applies to Google-managed base images, not arbitrary container images deployed directly to Cloud Run. Google says existing decommissioned workloads may be disabled rather than promising an immediate universal shutdown, and schedule dates may be delayed.
