Unreleased

Added

  • The operator-sdk olm-catalog gen-csv command now produces indented JSON for the alm-examples annotation. (#1793)
  • Added flag --dep-manager to command operator-sdk print-deps to specify the type of dependency manager file to print. The choice of dependency manager is inferred from top-level dependency manager files present if --dep-manager is not set. (#1819)
  • Ansible based operators now gather and serve metrics about each custom resource on port 8686 of the metrics service. (#1723)
  • Generating and serving info metrics about each custom resource. By default these metrics are exposed on port 8686. (#1277)

Changed

  • The Helm operator now uses the CR name for the release name for newly created CRs. Existing CRs will continue to use their existing UID-based release name. When a release name collision occurs (when CRs of different types share the same name), the second CR will fail to install with an error about a duplicate name. (#1818)
  • Commands olm uninstall and olm status no longer use a --version flag to specify OLM version. This information is now retrieved from the running cluster. (#1634)

Deprecated

Removed

  • Removed flag --as-file from command operator-sdk print-deps, which now only prints packages and versions in dependency manager file format. The choice of dependency manager type is set by --dep-manager or inferred from top-level dependency manager files present if --dep-manager is not set. (#1819)

Bug Fixes

  • Configure the repo path correctly in operator-sdk add crd and prevent the command from running outside of an operator project. (#1660)
  • In the Helm operator, skip owner reference injection for cluster-scoped resources in release manifests. The Helm operator only supports namespace-scoped CRs, and namespaced resources cannot own cluster-scoped resources. (#1817)
  • Package manifests generated with gen-csv respect the --operator-name flag, channel names are checked for duplicates before (re-)generation. (#1693)

v0.10.0

Added

  • Document new compile-time dependency mercurial in user-facing documentation. (#1683)
  • Adds new flag --zap-time-encoding to the flagset provided by pkg/log/zap. This flag configures the timestamp format produced by the zap logger. See the logging doc for more information. (#1529)

Changed

  • Breaking change: CSV config field role-path is now role-paths and takes a list of strings. Users can now specify multiple Role and ClusterRole manifests using role-paths. (#1704)
  • Make ready package idempotent. Now, a user can call Set() or Unset() to set the operator's readiness without knowing the current state. (#1761)

Bug Fixes

  • Check if metadata.annotations['alm-examples'] is non-empty before creating contained CR manifests in the scorecard. (#1789)

v0.9.0

Added

  • Adds support for building OCI images with podman, e.g. operator-sdk build --image-builder=podman. (#1488)
  • New option for operator-sdk up local --enable-delve, which can be used to start the operator in remote debug mode with the delve debugger listening on port 2345. (#1422)
  • Enables controller-runtime metrics in Helm operator projects. (#1482)
  • New flags --vendor and --skip-validation for operator-sdk new that direct the SDK to initialize a new project with a vendor/ directory, and without validating project dependencies. vendor/ is not written by default. (#1519)
  • Generating and serving info metrics about each custom resource. By default these metrics are exposed on port 8686. (#1277)
  • Scaffold a pkg/apis/<group>/group.go package file to avoid go/build errors when running Kubernetes code generators. (#1401)
  • Adds a new extra variable containing the unmodified CR spec for ansible based operators. #1563
  • New flag --repo for subcommands new and migrate specifies the repository path to be used in Go source files generated by the SDK. This flag can only be used with Go modules. (#1475)
  • Adds --go-build-args flag to operator-sdk build for providing additional Go build arguments. (#1582)
  • New flags --csv-channel and --default-channel for subcommand gen-csv that add channels to and update the package manifest in deploy/olm-catalog/<operator-name> when generating a new CSV or updating an existing one. (#1364)
  • Adds go.mod and go.sum to switch from dep to Go modules to manage dependencies for the SDK project itself. (#1566)
  • New flag --operator-name for operator-sdk olm-catalog gen-csv to specify the operator name, ex. memcached-operator, to use in CSV generation. The project's name is used (old behavior) if --operator-name is not set. (#1571)
  • New flag --local-operator-flags for operator-sdk test local --up-local to specify flags to run a local operator with during a test. (#1509)

Changed

  • Upgrade the version of the dependency controller-runtime from v0.1.10 to v0.1.12. (#1612)
  • Remove TypeMeta declaration from the implementation of the objects (#1462)
  • Relaxed API version format check when parsing pkg/apis in code generators. API dir structures can now be of the format pkg/apis/<group>/<anything>, where <anything> was previously required to be in the Kubernetes version format, ex. v1alpha1. (#1525)
  • The SDK and operator projects will work outside of $GOPATH/src when using Go modules. (#1475)
  • CreateMetricsService() function from the metrics package accepts a REST config (*rest.Config) and an array of ServicePort objects ([]v1.ServicePort) as input to create Service metrics. CRPortName constant is added to describe the string of custom resource port name. (#1560 and #1626)
  • Changed the flag --skip-git-init to --git-init. This changes the default behavior of operator-sdk new to not initialize the new project directory as a git repository with git init. This behavior is now opt-in with --git-init. (#1588)
  • operator-sdk new will no longer create the initial commit for a new project, even with --git-init=true. (#1588)
  • When errors occur setting up the Kubernetes client for RBAC role generation, operator-sdk new --type=helm now falls back to a default RBAC role instead of failing. (#1627)

Removed

  • The SDK no longer depends on a vendor/ directory to manage dependencies only if using Go modules. The SDK and operator projects will only use vendoring if using dep, or modules and a vendor/ dir is present. (#1519)
  • Breaking change: ExposeMetricsPort is removed and replaced with CreateMetricsService() function. PrometheusPortName constant is replaced with OperatorPortName. (#1560)
  • Removes Gopkg.toml and Gopkg.lock to drop the use of dep in favor of Go modules to manage dependencies for the SDK project itself. (#1566)

v0.8.2

Bug Fixes

  • Fixes header file content validation when the content contains empty lines or centered text. (#1544)
  • Generated CSV's that include a deployment install strategy will be checked for a reference to metadata.annotations['olm.targetNamespaces'], and if one is not found a reference will be added to the WATCH_NAMESPACE env var for all containers in the deployment. This is a bug because any other value that references the CSV's namespace is incorrect. (#1396)
  • Build -trimpath was not being respected. $GOPATH was not expanding because exec.Cmd{} is not executed in a shell environment. (#1535)
  • Running the scorecard with --olm-deployed will now only use the first CR set in either the cr-manifest config option or the CSV's metadata.annotations['alm-examples'] as was intended, and access manifests correctly from the config. (#1565)
  • Use the correct domain names when generating CRD's instead that of the first CRD to be parsed. (#1636)

v0.8.1

Bug Fixes

  • Fixes a regression that causes Helm RBAC generation to contain an empty custom ruleset when the chart's default manifest contains only namespaced resources. (#1456)
  • Fixes an issue that causes Helm RBAC generation to fail when creating new operators with a Kubernetes context configured to connect to an OpenShift cluster. (#1461)

v0.8.0

Added

  • New option for operator-sdk build --image-builder, which can be used to specify which image builder to use. Adds support for buildah. (#1311)
  • Manager is now configured with a new DynamicRESTMapper, which accounts for the fact that the default RESTMapper, which only checks resource types at startup, can't handle the case of first creating a CRD and then an instance of that CRD. (#1329)
  • Unify CLI debug logging under a global --verbose flag (#1361)
  • Go module support by default for new Go operators and during Ansible and Helm operator migration. The dependency manager used for a new operator can be explicitly specified for new operators through the --dep-manager flag, available in operator-sdk new and operator-sdk migrate. dep is still available through --dep-manager=dep. (#1001)
  • New optional flag --custom-api-import for operator-sdk add controller to specify that the new controller reconciles a built-in or external Kubernetes API, and what import path and identifier it should have. (#1344)
  • Operator Scorecard plugin support (#1379). Documentation for scorecard plugins can be found in the main scorecard doc: doc/test-framework/scorecard.md

Changed

  • When Helm operator projects are created, the SDK now generates RBAC rules in deploy/role.yaml based on the chart's default manifest. (#1188)
  • When debug level is 3 or higher, we will set the klog verbosity to that level. (#1322)
  • Relaxed requirements for groups in new project API's. Groups passed to operator-sdk add api's --api-version flag can now have no subdomains, ex core/v1. See (#1191) for discussion. (#1313)
  • Renamed --docker-build-args option to --image-build-args option for build subcommand, because this option can now be shared with other image build tools than docker when --image-builder option is specified. (#1311)
  • Reduces Helm release information in CR status to only the release name and manifest and moves it from status.conditions to a new top-level deployedRelease field. (#1309)
    • WARNING: Users with active CRs and releases who are upgrading their helm-based operator should upgrade to one based on v0.7.0 before upgrading further. Helm operators based on v0.8.0+ will not seamlessly transition release state to the persistent backend, and will instead uninstall and reinstall all managed releases.
  • Go operator CRDs are overwritten when being regenerated by operator-sdk generate openapi. Users can now rely on +kubebuilder annotations in their API code, which provide access to most OpenAPIv3 validation properties (the full set will be supported in the near future, see this PR) and other CRD fields. (#1278)
  • Use registry.access.redhat.com/ubi7/ubi-minimal:latest base image for the Go and Helm operators and scorecard proxy (#1376)
  • Allow "Owned CRDs Have Resources Listed" scorecard test to pass if the resources section exists

Removed

  • The SDK will no longer run defaulter-gen on running operator-sdk generate k8s. Defaulting for CRDs should be handled with mutating admission webhooks. (#1288)
  • The --version flag was removed. Users should use the operator-sdk version command. (#1444)
  • Breaking Change: The test cluster subcommand and the corresponding --enable-tests flag for the build subcommand have been removed (#1414)
  • Breaking Change: The --cluster-scoped flag for operator-sdk new has been removed so it won't scaffold a cluster-scoped operator. Read the operator scope documentation on the changes needed to run a cluster-scoped operator. (#1434)

Bug Fixes

v0.7.1

Bug Fixes

  • Pin dependency versions in Ansible build and test framework Dockerfiles to fix broken build and test framework images. (#1348)
  • In Helm-based operators, when a custom resource with a failing release is reverted back to a working state, the ReleaseFailed condition is now correctly removed. (#1321)

v0.7.0

Added

Changed

  • Updated the helm-operator to store release state in kubernetes secrets in the same namespace of the custom resource that defines the release. (#1102)
    • WARNING: Users with active CRs and releases who are upgrading their helm-based operator should not skip this version. Future versions will not seamlessly transition release state to the persistent backend, and will instead uninstall and reinstall all managed releases.
  • Change namespace-manifest flag in scorecard subcommand to namespaced-manifest to match other subcommands
  • Subcommands of operator-sdk generate are now verbose by default. (#1271)
  • operator-sdk olm-catalog gen-csv parses Custom Resource manifests from deploy/crds or a custom path specified in csv-config.yaml, encodes them in a JSON array, and sets the CSV's metadata.annotations.alm-examples field to that JSON. (#1116)

Bug Fixes

  • Fixed an issue that caused operator-sdk new --type=helm to fail for charts that have template files in nested template directories. (#1235)
  • Fix bug in the YAML scanner used by operator-sdk test and operator-sdk scorecard that could result in a panic if a manifest file started with --- (#1258)

v0.6.0

Added

  • New flags for operator-sdk new --type=helm, which can be used to populate the project with an existing chart. (#949)
  • Command operator-sdk olm-catalog flag --update-crds optionally copies CRD's from deploy/crds when creating a new CSV or updating an existing CSV, and --from-version uses another versioned CSV manifest as a base for a new CSV version. (#1016)
  • New flag --olm-deployed to direct the scorecard command to only use the CSV at --csv-path for manifest data, except for those provided to --cr-manifest. (#1044)
  • Command version prints the version of operator-sdk. (#1171)

Changed

  • Changed the Go, Helm, and Scorecard base images to registry.access.redhat.com/ubi7-dev-preview/ubi-minimal:7.6 (#1142)
  • CSV manifest are now versioned according to the operator-registry manifest format. See issue #900 for more details. (#1016)
  • Unexported CleanupNoT function from pkg/test, as it is only intended to be used internally (#1167)

Bug Fixes

  • Fix issue where running operator-sdk test local --up-local would sometimes leave a running process in the background after exit (#1089)

v0.5.0

Added

  • Updated the Kubernetes dependencies to 1.13.1 (#1020)
  • Updated the controller-runtime version to v0.1.10. See the controller-runtime v0.1.10 release notes for new features and bug fixes. (#1020)
  • By default the controller-runtime metrics are exposed on port 8383. This is done as part of the scaffold in the main.go file, the port can be adjusted by modifying the metricsPort variable. #786
  • A new command operator-sdk olm-catalog to be used as a parent for SDK subcommands generating code related to Operator Lifecycle Manager (OLM) Catalog integration, and subcommand operator-sdk olm-catalog gen-csv which generates a Cluster Service Version for an operator so the OLM can deploy the operator in a cluster. (#673)
  • Helm-based operators have leader election turned on by default. When upgrading, add environment variable POD_NAME to your operator's Deployment using the Kubernetes downward API. To see an example, run operator-sdk new --type=helm ... and see file deploy/operator.yaml. #1000
  • A new command operator-sdk generate openapi which generates OpenAPIv3 validation specs in Go and in CRD manifests as YAML. (#869)
  • The operator-sdk add api command now generates OpenAPIv3 validation specs in Go for that API, and in all CRD manifests as YAML.

Changed

  • In new Helm operator projects, the scaffolded CR spec field now contains the default values.yaml from the generated chart. (#967)

Deprecated

Removed

Bug Fixes

v0.4.1

Bug Fixes

Added

  • A new command operator-sdk migrate which adds a main.go source file and any associated source files for an operator that is not of the "go" type. (#887 and #897)
  • New commands operator-sdk run ansible and operator-sdk run helm which run the SDK as ansible and helm operator processes, respectively. These are intended to be used when running in a Pod inside a cluster. Developers wanting to run their operator locally should continue to use up local. (#887 and #897)
  • Ansible operator proxy added the cache handler which allows the get requests to use the operators cache. #760
  • Ansible operator proxy added ability to dynamically watch dependent resource that were created by ansible operator. #857
  • Ansible-based operators have leader election turned on by default. When upgrading, add environment variable POD_NAME to your operator's Deployment using the Kubernetes downward API. To see an example, run operator-sdk new --type=ansible ... and see file deploy/operator.yaml.
  • A new command operator-sdk scorecard which runs a series of generic tests on operators to ensure that an operator follows best practices. For more information, see the Scorecard Documentation

Changed

  • Ansible Operator CR status better aligns with conventions. (#639)

Added

  • A new command operator-sdk print-deps which prints Golang packages and versions expected by the current Operator SDK version. Supplying --as-file prints packages and versions in Gopkg.toml format. (#772)
  • Add cluster-scoped flag to operator-sdk new command (#747)

Changed

  • Moved the rendering of deploy/operator.yaml to the operator-sdk new command instead of operator-sdk build

v0.0.6

Added

  • Added operator-sdk up command to help deploy an operator. Currently supports running an operator locally against an existing cluster e.g operator-sdk up local --kubeconfig=<path-to-kubeconfig> --namespace=<operator-namespace>. See operator-sdk up -h for help. #219 #274
  • Added initial default metrics to be captured and exposed by Prometheus. #323 exposes the metrics port and #349 adds the initial default metrics.
  • Added initial test framework for operators #377, #392, #393

Changed

  • All the modules in pkg/sdk have been combined into a single package. action, handler, informer types and query pkgs have been consolidated into pkg/sdk. #242
  • The SDK exposes the Kubernetes clientset via k8sclient.GetKubeClient() #295
  • The SDK now vendors the k8s code-generators for an operator instead of using the prebuilt image gcr.io/coreos-k8s-scale-testing/codegen:1.9.3 #319
  • The SDK exposes the Kubernetes rest config via k8sclient.GetKubeConfig() #338
  • Use time.Duration instead of int for sdk.Watch #427

Fixed
