Runtimes on Google Cloud's buildpacks are base images that include components and operating system,
software required to build and execute code written for a specific
programming language, and software to support your function.
Runtime components are regularly updated with security and bug fixes.
To maintain stability, Google Cloud's buildpacks avoids implementing breaking
features or breaking changes into the runtime. Breaking changes will be
announced in advance in Google Cloud's buildpacksrelease notes.
When a language version is no longer actively maintained by the respective
community, Google Cloud's buildpacks will also stop providing maintenance and support for
that language runtime. Before a runtime reaches the deprecation phase as
described in theruntimes support schedule, Google will
provide a notification to customers in the Google Cloud console.
Google may make changes to any runtime's support schedule or lifecycle in
accordance with the terms of your agreement for the use of Google Cloud
services.
Notification Period
Google Cloud's buildpacks will begin issuing notifications 90 days before the runtime
reaches deprecation. Upon notification, you should prepare to upgrade your
function to a newersupported runtime.
Deprecation and Decommissioning
When a component is no longer actively maintained, Google Cloud's buildpacks may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 followingschedule,
the deprecation date is the start of the deprecation period and ends at the beginning
of the decommission date. The decommission date indicates the start of the decommission period.
During the deprecation period, you can generally continue to create new
workloads and update existing workloads using the runtime. You should use this
time to migrate workloads that use the deprecated runtime to a more up-to-date
runtime.
After the decommission date, you can no longer create new workloads or update
existing workloads using the runtime. You must choose a more up-to-date runtime
to deploy your workloads. Workloads that continue to use a decommissioned
runtime may be disabled.
Support Schedule
Here is the list of supported Google Cloud's buildpacks 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.
