That can be done in

libflexkube/pkg/container/containers.go

Lines 322 to 340 in ef0532a

	// recreate is a helper, which removes container from current state and creates new one from
	// desired state.
	func (c *containers) recreate(n string) error {
	if err := c.currentState.RemoveContainer(n); err != nil {
	return fmt.Errorf("failed removing old container to recreate it: %w", err)
	}
	c.currentState[n] = nil
	err := c.desiredState.CreateAndStart(n)
	c.currentState[n] = c.desiredState[n]
	if err != nil {
	return fmt.Errorf("creating and starting new container %q: %w", n, err)
	}
	return nil
	}

, maybe we could create a config container or something using new image?
