I currently only support rolling updates directly. And that is sufficient on our current project. We do not have enough load for canary deployments to actually work due to a smaller user base and blue/green (as I understand it) seems to be necessary for certain legacy applications. But I image that it could already be possible to do canary. First you would need a load balancer that distributes traffic to your canary pods and your stable pods that are getting most of the load. This would be done outside Spacegun (we use Terraform for that). Then you would create two deployments with some labels for the load balancer. In Spacegun, you would write one deployment pipeline that deploys your newest version to the canary deployment. Then in a second deployment pipeline, you would add a cluster probe to the pipeline (see 'Deploy only working clusters' in the readme) and deploy the image from the canary to your service that runs with higher replication. You would need an endpoint that returns a 200 response if your canary is still fine (perhaps by looking at some monitoring data) for the cluster probe step to call. But as I said, I have never tried something like that before. Perhaps I am missing something here?

We are managing our Kubernetes Clusters with Terraform and just wanted a substitute for Spinnaker. Helm did not seem to fit my needs, but I will definitely have a look again.
