v1.21.0
(go/v3):For golang-language based operators, fix suite test using global cfg
In the suite test files, replace cfg, err := testEnv.Start() with:
var err error
// cfg is defined in this file globally.
cfg, err = testEnv.Start()
Note: You can find suite test files scaffold for the APIs created for your project
such as api/webhook_suitetest.go directory as for your controllers in controllers/suite_test.go.
See #4863 for more details.
For Golang-based operators, update Dockerfile if you are using the declarative/v1 plugin
If you are using the declarative/v1 plugin for your scaffolds, then following the steps to update the Dockerfile.
a) After COPY controllers/ controllers/ add:
# https://github.com/kubernetes-sigs/kubebuilder-declarative-pattern/blob/master/docs/addon/walkthrough/README.md#adding-a-manifest
# Stage channels and make readable
COPY channels/ /channels/
RUN chmod -R a+rx /channels/
b) After the COPY --from=builder /workspace/manager .” add:
# copy channels
COPY --from=builder /channels /channels
See #4863 for more details.
(go/v3):For Golang-based operators, upgrade controller-runtime from v0.11.0 to v0.11.2 and Kubernetes deps from 1.23.0 to 1.23.5
Update your go.mod by replacing sigs.k8s.io/controller-runtime v0.11.0 with sigs.k8s.io/controller-runtime v0.11.2 and run go mod tidy
to update the K8s dependencies.
See #4863 for more details.
For Golang/Helm/Ansible-based operators, upgrade kube-rbac-proxy image from v0.8.0 to v0.11.0. (For further information see the kube-rbac-proxy release notes)
Update the tag version used for the image gcr.io/kubebuilder/kube-rbac-proxy in the file config/default/manager_auth_proxy_patch.yaml.
Replace gcr.io/kubebuilder/kube-rbac-proxy:v0.8.0 with gcr.io/kubebuilder/kube-rbac-proxy:v0.11.0
See #4863 for more details.
For Golang-based operators, change Makefile targets to replace go get with go install
The targets kustomize, controller-gen and envtest were changed. Update the Makefile replacing:
CONTROLLER_GEN = $(shell pwd)/bin/controller-gen
.PHONY: controller-gen
controller-gen: ## Download controller-gen locally if necessary.
$(call go-get-tool,$(CONTROLLER_GEN),sigs.k8s.io/controller-tools/cmd/controller-gen@v0.8.0)
KUSTOMIZE = $(shell pwd)/bin/kustomize
.PHONY: kustomize
kustomize: ## Download kustomize locally if necessary.
$(call go-get-tool,$(KUSTOMIZE),sigs.k8s.io/kustomize/kustomize/v3@v3.8.7)
ENVTEST = $(shell pwd)/bin/setup-envtest
.PHONY: envtest
envtest: ## Download envtest-setup locally if necessary.
$(call go-get-tool,$(ENVTEST),sigs.k8s.io/controller-runtime/tools/setup-envtest@latest)
# go-get-tool will 'go get' any package $2 and install it to $1.
PROJECT_DIR := $(shell dirname $(abspath $(lastword $(MAKEFILE_LIST))))
define go-get-tool
@[ -f $(1) ] || { \

go mod init tmp ;\
