Even if you set kustomize: true, DevSpace only renders the manifest templates using kustomize but the actual deployment will be executed using kubectl apply. A Kustomization object defines the source of Kubernetes manifests by referencing an object managed by source-controller, the path to the Kustomization file within that source, and the interval at which the kustomize build output is applied on the cluster. Using this pattern it provides various features including resource namespacing, modification of metadata, and generation of Kubernetes Secrets - all without editing the source manifests. Above, that is the blue-green namespace. Kustomize is an increasingly popular tool for managing Kubernetes manifests. I have a couple of overlays (dev, stg, prod) pulling data from multiple bases where each base contains a single service so that each overlay can pick and choose what services it needs.
