Runtime support

Runtimes on Cloud Run functions are base images that include components and operating system,software required to build and execute code written for a specificprogramming language, and software to support your function.

Cloud Run functions applies updates to runtimes in accordance with your selectedsecurity updatepolicy.

Diagram outlining the stages in the lifecycle of a Cloud Run functionsruntime

Runtimes are available in different release stages, such as Preview orGeneral Availability (GA). For more information, see theproduct launch stages.

Preview

If you deploy a workload using the Google Cloud CLI when a runtime is in Preview, usethegcloud beta functions deploycommand.

General Availability (GA)

During theGeneral Availability (GA) support window:

  • Runtime components are regularly updated with security and bug fixes.
  • Updates are applied in accordance with your workload'ssecurity updatepolicy.
  • To maintain stability, Cloud Run functions avoids implementing breakingfeatures or breaking changes into the runtime. Breaking changes will beannounced in advance in Cloud Run functionsrelease notes.

When a language version is no longer actively maintained by the respectivecommunity, Cloud Run functions will also stop providing maintenance and support forthat language runtime. Before a runtime reaches the deprecation phase asdescribed in theruntimes support schedule, Google willprovide a notification to customers in the Google Cloud console.

Google may make changes to any runtime's support schedule or lifecycle inaccordance with the terms of your agreement for the use of Google Cloudservices.

Notification Period

Cloud Run functions will begin issuing notifications 90 days before the runtimereaches deprecation. Upon notification, you should prepare to upgrade yourfunction to a newersupported runtime.

Deprecation and Decommissioning

When a component is no longer actively maintained, Cloud Run functions maydeprecate and eventually remove the runtime.

This has three aspects: a publication of the deprecation date, a deprecationperiod, and a decommission date. In the followingschedule,the deprecation date is the start of the deprecation period and ends at the beginningof the decommission date. The decommission date indicates the start of the decommission period.

During the deprecation period, you can generally continue to create newworkloads and update existing workloads using the runtime. You should use thistime to migrate workloads that use the deprecated runtime to a more up-to-dateruntime.

After the decommission date, you can no longer create new workloads or updateexisting workloads using the runtime. You must choose a more up-to-date runtimeto deploy your workloads. Workloads that continue to use a decommissionedruntime may be disabled.

Support Schedule

Here is the list of supported Cloud Run functions runtimes, as well as runtimesthat have been deprecated or decommissioned.

Based on qualification and stability of releases, availability and key datesmight be delayed. A blank deprecation or decommission date means that phase hasnot yet been scheduled. Revisit this page to stay up to date.

Note:Runtime ID is often used when deploying from the from the command lineor through Terraform

Note: Go'srelease policy states that each major Go release is supported until there are two newer major releases. Thus, depending on when newer versions of Go are made publicly available, key dates such as end of support, deprecation, and decommission might be postponed.
