Updating Helm-based projects for newer Operator SDK versions

OKD 4.11 supports Operator SDK 1.22.0. If you already have the 1.16.0 CLI installed on your workstation, you can update the CLI to 1.22.0 by installing the latest version.

However, to ensure your existing Operator projects maintain compatibility with Operator SDK 1.22.0, update steps are required for the associated breaking changes introduced since 1.16.0. You must perform the update steps manually in any of your Operator projects that were previously created or maintained with 1.16.0.

Updating Helm-based Operator projects for Operator SDK 1.22.0

The following procedure updates an existing Helm-based Operator project for compatibility with 1.22.0.

Prerequisites

  • Operator SDK 1.22.0 installed.

  • An Operator project created or maintained with Operator SDK 1.16.0.

Procedure

  1. Make the following changes to the config/default/manager_auth_proxy_patch.yaml file:

    1. ...
    2. spec:
    3. template:
    4. spec:
    5. containers:
    6. - name: kube-rbac-proxy
    7. image: registry.redhat.io/openshift4/ose-kube-rbac-proxy:v4.11 (1)
    8. args:
    9. - "--secure-listen-address=0.0.0.0:8443"
    10. - "--upstream=http://127.0.0.1:8080/"
    11. - "--logtostderr=true"
    12. - "--v=0" (2)
    13. ...
    14. resources:
    15. limits:
    16. cpu: 500m
    17. memory: 128Mi
    18. requests:
    19. cpu: 5m
    20. memory: 64Mi (3)
    1Update the tag version from v4.10 to v4.11.
    2Reduce the debugging log level from —v=10 to —v=0.
    3Add resource requests and limits.
  2. Make the following changes to your Makefile:

    1. Enable support for image digests by adding the following environment variables to your Makefile:

      Old Makefile

      1. BUNDLE_IMG ?= $(IMAGE_TAG_BASE)-bundle:v$(VERSION)
      2. ...

      New Makefile

      1. BUNDLE_IMG ?= $(IMAGE_TAG_BASE)-bundle:v$(VERSION)
      2. # BUNDLE_GEN_FLAGS are the flags passed to the operator-sdk generate bundle command
      3. BUNDLE_GEN_FLAGS ?= -q --overwrite --version $(VERSION) $(BUNDLE_METADATA_OPTS)
      4. # USE_IMAGE_DIGESTS defines if images are resolved via tags or digests
      5. # You can enable this value if you would like to use SHA Based Digests
      6. # To enable set flag to true
      7. USE_IMAGE_DIGESTS ?= false
      8. ifeq ($(USE_IMAGE_DIGESTS), true)
      9. BUNDLE_GEN_FLAGS += --use-image-digests
      10. endif
    2. Edit your Makefile to replace the bundle target with the BUNDLE_GEN_FLAGS environment variable:

      Old Makefile

      1. $(KUSTOMIZE) build config/manifests | operator-sdk generate bundle -q --overwrite --version $(VERSION) $(BUNDLE_METADATA_OPTS)

      New Makefile

      1. $(KUSTOMIZE) build config/manifests | operator-sdk generate bundle $(BUNDLE_GEN_FLAGS)
    3. Edit your Makefile to update opm to version 1.23.0:

      1. .PHONY: opm
      2. OPM = ./bin/opm
      3. opm: ## Download opm locally if necessary.
      4. ifeq (,$(wildcard $(OPM)))
      5. ifeq (,$(shell which opm 2>/dev/null))
      6. @{ \
      7. set -e ;\
      8. mkdir -p $(dir $(OPM)) ;\
      9. OS=$(shell go env GOOS) && ARCH=$(shell go env GOARCH) && \
      10. curl -sSLo $(OPM) https://github.com/operator-framework/operator-registry/releases/download/v1.23.0/$${OS}-$${ARCH}-opm ;\ (1)
      11. chmod +x $(OPM) ;\
      12. }
      13. else
      14. OPM = $(shell which opm)
      15. endif
      16. endif
      1Replace v1.19.1 with v1.23.0.
    4. Apply the changes to your Makefile and rebuild your Operator by entering the following command:

      1. $ make
