v9.0.0

Breaking change ahead! [#170]

This release cleans up lots of K8s targets and renames targets and variables in a more matching manner.
Please take the time to revise the changes for your project if you use them after a major version upgrade.

Changed

General K8s and k8s dogu-related

• the k8s variable IMAGE_DEV no longer contains a version tag because it makes editing YAML files easier
  • you can append ${VERSION} as it should already be defined in your main makefile.
• k8s tool versions are now replaceable by these variables
  • BINARY_YQ_4_VERSION, BINARY_HELM_VERSION, and CONTROLLER_GEN_VERSION can now be customized if needed
    • simply set these variables before the inclusion of any k8s*.mk files
  • the corresponding path and version variables move to the same place in k8s.mk for better maintenance experience
• the variable K8S_RESOURCE_TEMP_FOLDER no longer contains a make subdirectory to simplify the directory structure in target/
• the k8s/dogu variable DOGU_JSON_DEV_FILE is no longer a relative path but absolute
• The k8s/dogu target k8s-create-temporary-resource renames to create-dogu-resource
  • its output can be optionally defined by setting K8S_RESOURCE_DOGU but defaults to `target/k8s/${ARTIFACT_ID}.yaml

Helm / components

• the k8s/helm target helm-generate-chart renames to helm-generate
  • helm-generate also provides now optional post-exec targets by setting HELM_POST_GENERATE_TARGETS
• the k8s/helm target helm-apply also executes image-import
  • this target also allows now optional pre-exec targets by setting HELM_PRE_APPLY_TARGETS
• the k8s/helm target helm-chart-import also executes image-import
• these overridable variables rename to their respective counterparts:
  • K8S_HELM_TARGET to HELM_TARGET_DIR
  • K8S_HELM_RESSOURCES to HELM_SOURCE_DIR
  • K8S_HELM_ARTIFACT_NAMESPACE to HELM_ARTIFACT_NAMESPACE

Helm-CRD

• the k8s/crd targets manifests and generate are no longer specific to the controller implementation
  • manifests can be found by including build/make/k8s-crd.mk
    • this target also allows now optional post-exec targets by setting CRD_POST_MANIFEST_TARGETS
  • generate can be found by including build/make/k8s-controller.mk
• the k8s/crd target crd-helm-generate-chart renames to crd-helm-generate and executes prior two checks: validate-crd-chart, validate-crd
  • crd-helm-generate allows also now optional post-exec targets by setting K8S_POST_CRD_HELM_GENERATE_TARGETS

k8s controller

• the k8s/controller target generate renames to generate-deepcopy for better understandability

Removed

• the k8s targets k8s-delete, k8s-generate, and k8s-apply are removed in favor of Helm targets
  • along with these targets, the variables K8S_PRE_GENERATE_TARGETS, PRE_APPLY_TARGETS, K8S_POST_GENERATE_TARGETS are removed
  • instead these targets take their place: HELM_PRE_GENERATE_TARGETS, HELM_PRE_APPLY_TARGETS/COMPONENT_PRE_APPLY_TARGETS, HELM_POST_GENERATE_TARGETS
• the k8s/controller target k8s-create-temporary-resource which used to produce monolithic YAML resources is removed

Added

• the k8s target check-all-vars executes now also the check-k8s-image-env-var check
• the k8s/helm targets ${HELM_TARGET_DIR}/Chart.yaml (and thus helm-generate) may execute pre-targets configured in the new variable HELM_PRE_GENERATE_TARGETS
  • this target also checks with validate-chart if a source Helm Chart.yaml exists
• the k8s/helm target copy-helm-files copies all Helm files (including Chart.yaml) from the source directory to target/k8s/helm
  ${COMPONENT_PRE_APPLY_TARGETS}
• adds k8s/crd target validate-crd-chart to check for a source CRD Chart.yaml
• adds k8s/crd target validate-crd to check if K8S_CRD_COMPONENT_SOURCE was properly set
• adds k8s/crd target crd-helm-lint to lint the CRD's Helm chart
• adds k8s/component target helm-lint to lint the component's Helm chart
