cf-deployment transition to Xenial stemcell
CF-Deployment default to Ubuntu 16.04 (Xenial Xerus) BOSH stemcells in late-Fall/early-Winter 2018.
Canonical will stop providing security updates for the current Ubuntu 14.04 (Trusty Tahr), the current cf-deployment default, in April 2019 per their official support lifecycle policy.
CF-Deployment plans to transition to the fully-supported Xenial stemcell lines well before April 2019 and we’ll need each component team to validate the Xenial stemcell against their components before making the switch.
If each component's features are confirmed compatible before the end of September 2018, we should be able to hit our intended target for the transition.
CF-D/Xenial Status to-date:
This message is a gentle invitation to begin/continue validating your component against Xenial.
Note that RelInt validates releases via CATs. The scope of CATs is purposely limited to validating core cf workflows.
The stability of cf-deployment releases assumes each component team executes a much deeper level of component-specific testing before integrating into cf-deployment.
For this reason, we don't/won't recommend using Xenial for production installs of cf-deployment nor make Xenial default in CF-D until each component team has validated that all its supported features are compatible with the Xenial stemcell.
We've proven Xenial can be run in a pipeline and CATs will pass so now's the time.
Please do due diligence and let us know when you've completed your validation.
And as always, please feel free to reach out to RelInt with any questions, issues, comments or suggestions you may have.
Thanks so much!
