Function InferWorkspaceImage

pkg/library/home/util.go:27–38

InferWorkspaceImage finds the first non-imported container component image in the flattened devfile template. This mirrors the selection rule used by the built-in persistent-home initializer to pick a "primary" workspace image. If no such component exists, it returns an empty string.

(dwTemplate *v1alpha2.DevWorkspaceTemplateSpec)

// persistent-home initializer to pick a "primary" workspace image.
// If no such component exists, it returns an empty string.
func InferWorkspaceImage(dwTemplate *v1alpha2.DevWorkspaceTemplateSpec) string {
	for _, component := range dwTemplate.Components {
		if component.Container == nil {
			continue
		}
		pluginSource := component.Attributes.GetString(constants.PluginSourceAttribute, nil)
		if pluginSource == "" || pluginSource == "parent" {
			return component.Container.Image
		}
	}
	return ""
