Google Cloud Run functions decommissions the Go 1.22 runtime
Google Cloud decommissioned the managed Cloud Run functions Go 1.22 runtime on 28 July 2026, blocking new deployments and updates while leaving remaining workloads liable to disablement.
Previous state
From 28 January until decommissioning, the managed Cloud Run functions Go 1.22 runtime was deprecated: customers could generally still create and redeploy workloads on it, and existing workloads continued to run, but GA-level runtime support had ended.
Current state
After the 28 July 2026 decommission date, customers can no longer create or update Cloud Run functions workloads with runtime ID go122. Existing workloads may be disabled, and the runtime receives no language, system-package or operating-system updates and no runtime support.
Affected users
Who needs to care
Cloud Run functions deployed with the Google-managed Go 1.22 runtime ID go122, including their owners and delivery pipelines that still select that runtime for creation or redeployment.
Required response
What to do
Inventory functions that use runtime ID go122, move their code and deployment configuration to a supported Go runtime, and redeploy on that supported runtime; new and updated workloads can no longer select Go 1.22.
Evidence boundary
What the source does not prove
The Cloud Run runtime lifecycle applies to workloads using Google-managed base images. Container images deployed directly to Cloud Run are outside this policy. Google notes that schedule dates can change; the official schedule last updated 1 September 2026 lists Go 1.22 deprecation on 28 January and decommission on 28 July 2026.
Lifecycle history
Dated event sequence
- Go 1.22 runtime entered deprecation
The deprecated period began; creation and redeployment generally remained available, while customers were expected to migrate to a newer supported runtime.
- Go 1.22 runtime entered decommission
New creation and updates stopped, runtime updates and support ended, and remaining workloads became eligible for disablement.
