Types

type RollingDeploymentStrategy

type RollingDeploymentStrategy struct {
	// contains filtered or unexported fields
}

RollingDeploymentStrategy is a Strategy which implements rolling deployments using the upstream Kubernetes RollingUpdater.

Currently, there are some caveats:

1. When there is no existing prior deployment, deployment delegates to another strategy. 2. The interface to the RollingUpdater is not very clean.

These caveats can be resolved with future upstream refactorings to RollingUpdater[1][2].
