StatefulRollout

[james-callahan]

Summary

I'd like to use a blue/green deployment strategy with a stateful application.

Use Cases

e.g. I have a stateful application and I want to keep the old version up until the new version has proven itself.

Suggested by @jessesuen in #132 (comment)

Aside from the Deployment resource, the only other native k8s resources that might need similar advanced deploy strategies are: StatefulSet and DaemonSet. But both of these resources have very different behaviors that would warrant an entirely new resource kind and controller. I don't think a generic approach could handle all three types because the manner in which these resources manage their pods are wildly different.
So while it's conceivable that we would introduce something like a StatefulRollout or DaemonRollout in the future, in all likelihood, these other kinds would need very specific/different implementations to mirror their k8s native counterparts.

Hi everyone, we're improving our infra and devops structure in my company and we are at the point of implementing blue-green deployment. Argo-rollouts looks like a really nice option for this, but unfortunately, lack of StatefulRollout hinders our use case.

We use Event Sourcing and CQRS, and we want to be able to deploy both our app and our view model, so that it can do its event replay in the next version and once that's done and the next version seems stable, we promote the next version. The important part is, we want the previous version to be available and in use while the event replay going for the next version, that's why blue-green deployment sounds nice for our case. This requires the next version of the app to be deployed with its own view model. That's why it will be great to have a StatefulRollout to achieve this with agro-rollouts.

Do we have any update on this project? We will use StatefulRollout pretty much in our CI/CD pipeline. Thanks a lot for any new information.

Any plans to prioritize this feature ?

any updates regarding this? any plans to prioritize it?

[gjborges]

it would be nice to have a new type of rollout for statefulsets. Any plans for this?
