When Skaffold deploys your application to Kubernetes, it goes through these steps:
In the default case (no manifest provided using the kubectl or kpt deployer ), skaffold deploy will do the following:
- the Skaffold renderer renders the final Kubernetes manifests: Skaffold replaces untagged image names in the Kubernetes manifests with the final tagged image names. It also might go through the extra intermediate step of expanding templates (for helm) or calculating overlays (for kustomize). Additionally some deployers (docker) do not render manifests as such don’t use this phase.
- the Skaffold deployer deploys the final Kubernetes manifests to the cluster (or to local docker for the docker deployer)
- the Skaffold deployer performs status checks and waits for the deployed resources to stabilize.
Skaffold supports the following tools for deploying applications:
Skaffold’s deploy configuration is set through the
skaffold.yaml. See each deployer’s page for more information
on how to configure them for use in Skaffold. It’s also possible to use
a combination of multiple deployers in a single project.
