Runtime Support
To keep your functions up-to-date and secure, we occasionally need you to update your functions and re-deploy them to use a supported runtime. Runtimes on Cloud Run functions include an operating system, software required to build and execute code written for a specific programming language, and software to support your functions. Cloud Run functions applies updates to runtimes in accordance with your selected security update policy.
Deprecation and Decommissioning
When a component is no longer actively maintained, Cloud Run functions may deprecate and eventually remove the runtime.
This has three aspects: a publication of the deprecation date, a deprecation period, and a decommission date. In the following tables, the deprecation date is the start of the deprecation period, while the decommission date indicates the start of the decommission period.
During the deprecation period, you can generally continue to create new functions and update existing functions using the runtime. You should use this time to migrate functions that use the deprecated runtime to a more up-to-date runtime.
After the decommission date, you can no longer create new functions or update existing functions using the runtime. You must choose a more up-to-date runtime to deploy your functions. Functions that continue to use a decommissioned runtime may be disabled.
Support Schedule
Here is the list of supported Cloud Run functions runtimes, as well as runtimes that have been deprecated or decommissioned.
Based on qualification and stability of releases, availability and key dates might be delayed. A blank deprecation or decommission date means that phase has not yet been scheduled. Revisit this page to stay up to date.
