Component Specirics

Deploy

Deploys resources described in kustomize.yaml (or kustomize.yaml.template)

Special case for CRD

User can copy definition of CRD in yaml format to <component-dir>/crds/*.yaml directory. These files will be processed before kustomize build will be executed

Note: on undeploy CRDs will retain (to preserver user's custom resources created after deployment of the component)

Same logic (see above) for undeploy applies for all CustomResourceDefinitions described in kustomize.yaml

Special case for Namespaces

deploy script will create a namespace (if it doesn't exist). If kustomize script will declare a namespace creation. Then this operation will be ignored. Custom label or annotations should be supplied as one of

• pre-deploy script
• patch in kustomize.yaml

undeploy script won't delete namespace (To preserve resoruces created after deployment of the component)
