Testing your Operator with Operator Framework

Overview

These instructions walk you through how to manually test that your Operator deploys correctly with Operator Framework, when packaged for the Operator Lifecycle Manager. Although your submission will always be tested as part of the CI you can accelerate the process by testing locally.

The tests described in this document can also be executed automatically in a single step using a test suite

A previous version of this document required quay.io, operator-courier and operator-marketplace to conduct the tests. This is no longer required.

However, note that you can easily check and test your bundles via operator-sdk bundle validate:

operator-sdk bundle validate ./bundle --select-optional suite=operatorframework

NOTE For further information about the options available with operator-sdk bundle validate run operator-sdk bundle validate --list-optional and operator-sdk bundle validate --help.

And then, if you used operator-sdk to build your project and bundle you can leverage in operator-sdk scorecard:

operator-sdk scorecard bundle

FOR OPENSHIFT COMMUNITY OPERATORS

For Openshift community operators make sure you understand and performed the required additional checks before publish your PR. See OKD/OpenShift Catalogs criteria and options.

Accepted Contribution formats

The process below assumes that you have a Kubernetes Operator in either of the two following formats supported by the Operator Framework:

bundle format (supported with 0.14.0 or newer)

(Legacy) packagemanifest format (mandatory for all OLM versions prior to 0.14.0 and earlier, supported on all available versions)

NOTE It is recommended to use the bundle format instead. This format still valid for backwards compatibility only and at some point will no longer to be supported.

$ tree my-operator/

└── my-operator.package.yaml

In both examples above my-operator is the name of your Operator which is available in 3 versions: 0.1.0, 0.5.0 and 1.0.0. If you are new to this or you don't have this format yet, refer to our contribution documentation. We will refer to both formats distinctively below where required.

Mixing packagemanifest style and bundle format style Operator versions in a single Operator package is not supported. All versions all need to be in either one or the other format.

Pre-Requisites

Kubernetes cluster

For "upstream-community" operators targeting Kubernetes and OperatorHub.io: * A running Kubernetes cluster; minikube or Kubernetes-in-Docker is the simplest approach

For "community" operators targeting OCP/OKD and OperatorHub on OpenShift: * access to a running production-like OpenShift 4 cluster, use try.openshift.com to get a cluster on infrastructure of your choice * or access to all-in-one OpenShift 4 cluster, use CodeReady Containers to get a cluster on your local machine

Container Tooling

You need an OCI compatible container toolchain on the system where you test your Operator. Support options are:

Operator Framework components

The following parts of the framework are used throughout the process and should be downloaded and put in your executable search path (Linux and Mac are supported):

Preparing file structure

Finally, if you haven't already done so, please clone this repository as well and create a branch:

git clone https://github.com/operator-framework/community-operators.git
cd community-operators/
git branch my-operator

For simplicity (and if your Operator has dependencies on other community Operators) put your my-operator directory in either of the community-operators (for OpenShift's OperatorHub) or upstream-community-operators (for OperatorHub.io) directory (or both).

cp -R my-operator/ community-operators/upstream-community-operators/

The name of the directory my-operator/ needs to match the Operator package name (without the slash) in either package.yaml (if you are using the packagemanifest format) or the container image label operators.operatorframework.io.bundle.package.v1 in the Dockerfile and annotations.yaml (if you are using the bundle format).

If you are just adding a new version of your Operator, please create a subdirectory following semver conventions in your existing package directory, for example:

cp -R my-operator/2.0.0 community-operators/upstream-community-operators/my-operator/

If you are using the packagemanifest format, don't forget to update the package.yaml file in the top-level directory to point to your new version/channels.

Operator Metadata Validation

If you are using packagemanifest format you will need to convert your metadata to bundle format for the validation step. In theory the previous operator-courier tool still works but it is no longer maintained.

Temporary conversion of packagemanifest to bundle

Suppose v2.0.0 is the version of the Operator you want to test convert to bundle format directory with the opm tool:

mkdir /tmp/my-operator-2.0.0-bundle/
cd /tmp/my-operator-2.0.0-bundle/
opm alpha bundle build --directory /path/to/my-operator/2.0.0/ --tag my-operator-bundle:v2.0.0 --output-dir .

This will have generated the bundle format layout in the current working directory /tmp/my-operator-2.0.0-bundle/:

$ tree .

/tmp/my-operator-2.0.0-bundle/
├── manifests
│   ├── my-operator-crd1.crd.yaml
│   ├── my-operator-crd2.crd.yaml
│   ├── my-operator-crd3.crd.yaml
│   └── my-operator.v2.0.0.clusterserviceversion.yaml
├── metadata
│   └── annotations.yaml
└── bundle.Dockerfile

Run the following validation command of the operator-sdk from within this directory.

operator-sdk bundle validate /tmp/my-operator-2.0.0-bundle/ --select-optional name=operatorhub

Using operator-sdk to validate your Operator

Validation using operator-sdk is only supported using the bundle format layout. See the previous step if you need to convert from packagemanifest.

Validation is done on a per-Operator version basis. If you are not already in the Operator versions directory, switch to it now, e.g.

cd my-operator/2.0.0/

With the Operator in bundle format use the operator-sdk to validate your bundle with the additional rules for community submissions:

operator-sdk bundle validate --select-optional name=operatorhub .

The output might look similar to this:

INFO[0000] Found annotations file                        bundle-dir=. container-tool=docker
INFO[0000] Could not find optional dependencies file     bundle-dir=. container-tool=docker
INFO[0000] All validation tests have completed successfully

If there are any errors or warnings they will be displayed there. The container-tool will be automatically determined given your environment. If you want to force to use podman instead of docker, supply the -b switch to the operator-sdk bundle validate command.

Any warnings here might turn into failing pipeline tests here. Please correct all issues displayed. A list of fields that are scanned can also be reviewed with this list.

Publishing your Operator metadata to a catalog for testing

Building a catalog using packagemanifest format

When your Operator metadata is formatted in packagemanifest layout you need to place it in the directory structure of the community-operators repository, according to pre-requisites step.

For example, assuming version 2.0.0 is the version you like to test:

$ tree upstream-community-operators/

upstream-community-operators/
│
...
│
└──my-operator/
    ├── 0.1.0
    │   ├── my-operator-crd1.crd.yaml
    │   ├── my-operator-crd2.crd.yaml
    │   └── my-operator.v0.1.0.clusterserviceversion.yaml
    ├── 0.5.0
    │   ├── my-operator-crd1.crd.yaml
    │   ├── my-operator-crd2.crd.yaml
    │   ├── my-operator-crd3.crd.yaml
    │   └── my-operator.v0.5.0.clusterserviceversion.yaml
    ├── 1.0.0
    │   ├── my-operator-crd1.crd.yaml
    │   ├── my-operator-crd2.crd.yaml
    │   ├── my-operator-crd3.crd.yaml
    │   └── my-operator.v1.0.0.clusterserviceversion.yaml
    ├── 2.0.0
    │   ├── my-operator-crd1.crd.yaml
    │   ├── my-operator-crd2.crd.yaml
    │   ├── my-operator-crd3.crd.yaml
    │   └── my-operator.v2.0.0.clusterserviceversion.yaml
    └── my-operator.package.yaml

You can build a catalog for OLM containing either all Operators or just yours with a Dockerfile like this

FROM quay.io/operator-framework/upstream-registry-builder as builder

COPY upstream-community-operators manifests
RUN /bin/initializer -o ./bundles.db

FROM scratch
COPY --from=builder /etc/nsswitch.conf /etc/nsswitch.conf
COPY --from=builder /bundles.db /bundles.db
COPY --from=builder /bin/registry-server /registry-server
COPY --from=builder /bin/grpc_health_probe /bin/grpc_health_probe
EXPOSE 50051
ENTRYPOINT ["/registry-server"]
CMD ["--database", "bundles.db"]

Simply adjust the second line to either include all OpenShift Community Operators (community-operators), or all OperatorHub.io Operators (upstream-community-operators) or just your Operator (e.g. upstream-community-operator/my-operator).

Place the Dockerfile in the top-level directory of your cloned copy of this repo, build it and push to a registry from where you can download it to your Kubernetes cluster later.

For example:

podman build -f catalog.Dockerfile -t my-test-catalog:latest .
podman tag my-test-catalog:latest quay.io/myaccount/my-test-catalog:latest
podman push quay.io/myaccount/my-test-catalog:latest

Building a catalog using bundles

When your Operator metadata is formatted in bundle layout you can optionally add it to the existing directory structure like described in the pre-requisites step. For building a catalog this is not required because with Operator bundles versions are incrementally added to an existing or empty catalog.

For example, assuming version 2.0.0 is the version you like to test:

$ tree my-operator/

my-operator/
├── 0.1.0
│   ├── manifests
│   │   ├── my-operator-crd1.crd.yaml
│   │   ├── my-operator-crd2.crd.yaml
│   │   ├── my-operator-crd3.crd.yaml
│   │   └── my-operator.v0.1.0.clusterserviceversion.yaml
│   ├── metadata
│   │   └── annotations.yaml
│   └── Dockerfile
├── 0.5.0
│   ├── manifests
│   │   ├── my-operator-crd1.crd.yaml
│   │   ├── my-operator-crd2.crd.yaml
│   │   ├── my-operator-crd3.crd.yaml
│   │   └── my-operator.v0.5.0.clusterserviceversion.yaml
│   ├── metadata
│   │   └── annotations.yaml
│   └── Dockerfile
├── 1.0.0
│   ├── manifests
│   │   ├── my-operator-crd1.crd.yaml
│   │   ├── my-operator-crd2.crd.yaml
│   │   ├── my-operator-crd3.crd.yaml
│   │   └── my-operator.v1.0.0.clusterserviceversion.yaml
│   ├── metadata
│   │   └── annotations.yaml
│   └── Dockerfile
└── 2.0.0
    ├── manifests
    │   ├── my-operator-crd1.crd.yaml
    │   ├── my-operator-crd2.crd.yaml
    │   ├── my-operator-crd3.crd.yaml
    │   └── my-operator.v2.0.0.clusterserviceversion.yaml
    ├── metadata
    │   └── annotations.yaml
    └── Dockerfile
...

Simply build your bundle using the Dockerfile that is part of every Operator bundle. If you are new to this format please consult the operator-registry documentation. If you used operator-sdk to develop your Operator you can also leverage its packaging tooling to create a bundle.

To build your bundle simply build the image and push it to a registry of your choice:

podman build -f 2.0.0/Dockerfile -t my-operator:v2.0.0 2.0.0/
podman push my-operator:v2.0.0 quay.io/myaccount/my-operator:v2.0.0

With the bundle published to a registry you can now leverage opm to add it to the existing catalog of community operators:

  • for OpenShift this is quay.io/openshift-community-operators/catalog:latest
  • for OperatorHub.io this is quay.io/operatorhubio/catalog:latest

opm will create a catalog image with your Operator added, like so:

opm index add --bundles quay.io/myaccount/my-operator:v2.0.0 --from-index quay.io/operatorhubio/catalog:latest --tag quay.io/myaccount/my-test-catalog:latest

You then push the resulting catalog image to a registry of your choice as well:

podman push quay.io/myaccount/my-test-catalog:latest

opm also supports multiple container tools via the -c switch. You can also omit the final step to build the catalog image and instead output the Dockerfile that would be used. Consult the help output for that via opm index add --help

You now have a catalog image available for OLM to install your Operator version from.

Testing Operator Deployment on Kubernetes

1. Installing Operator Lifecycle Manager

If you are not using OpenShift you first need to install the Operator Lifecycle Manager on your cluster.

The following steps assume you already have a running Kubernetes cluster that is currently selected as your current-context via kubectl. If you, you can quickly spin up a cluster using tools like KIND or minikube mentioned in the pre-requisites section , e.g.

kind create cluster

You can install the Operator Lifecycle Manager using either operator-sdk or kubectl.

Option 1: Install the Operator Lifecycle Manager using operator-sdk:

operator-sdk olm install

Verify that OLM installed correctly:

operator-sdk olm status

This should output something like the following:

INFO[0000] Fetching CRDs for version "0.16.1"
INFO[0000] Fetching resources for version "0.16.1"
INFO[0002] Successfully got OLM status for version "0.16.1"

packageserver                                   olm          ClusterServiceVersion       Installed
olm-operator-serviceaccount                     olm          ServiceAccount              Installed

system:controller:operator-lifecycle-manager                 ClusterRole                 Installed

Option 2: Install the Operator Lifecycle Manager using kubectl:

kubectl apply -f https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.17.0/crds.yaml
kubectl apply -f https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.17.0/olm.yaml

You can check if Operator Lifecycle Manager status via following command:

kubectl get pods -n olm

This should output something like the following:

NAME                                READY   STATUS    RESTARTS   AGE
catalog-operator-7b4788ffb5-9jggk   1/1     Running   0          23h
olm-operator-678d76b95c-r492j       1/1     Running   0          23h
operatorhubio-catalog-lqw72         1/1     Running   0          23h
packageserver-7cfd786c67-pwpnn      1/1     Running   0          23h
packageserver-7cfd786c67-tkwbm      1/1     Running   0          23h

Troubleshooting

If any problems are encountered at this step, verify that you have enough permissions to install OLM (you need to be cluster-admin to register its CRDs) and create an issue in the OLM tracker.

2. Adding the catalog containing your Operator

Create a CatalogSource instance in the olm namespace to reference in the Operator catalog image that contains your Operator version to test:

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: my-test-catalog
  namespace: olm
spec:
  sourceType: grpc
  image: quay.io/myaccount/my-test-catalog:latest

Deploy the CatalogSource resource:

kubectl apply -f catalog-source.yaml

If you created your test catalog containing all existing community operators, you should delete the default catalog that OLM ships with to avoid a lot of duplicate entries:

kubectl delete catalogsource operatorhubio-catalog -n olm

Verify your custom catalog got loaded:

$ kubectl get catalogsource -n olm
NAME                           DISPLAY     TYPE   PUBLISHER   AGE
my-test-catalog                            grpc               3m32s
[...]

Verify the health of your catalog:

kubectl get catalogsource my-test-catalog -n olm -o yaml

Troubleshooting

The status section of that object have the lastObservedState condition set to READY. If that is not the case (for example if the condition is set to CONNECTING) check the healthiness of the pod associated to the catalog in the same namespace.

kubectl get pod -n olm

The name of the pod will carry the name of the CatalogSource object plus 5 random characters. Usually the source of unhealthy catalogs is catalog pods with pull errors due to missing authentication against the registry or non-existent tags. If the pod is actually running check its logs:

kubectl logs my-test-catalog-zcq7h -n olm

If there are errors in this log please raise them in the operator-registry issue tracker as any problems caused by malformed bundle/packagemanifest metadata should have been caught during catalog creation.

3. View Available Operators

Inspect the list of loaded packagemanifests on the system with the following command to filter for your Operator

kubectl get packagemanifests | grep my-operator

The example should look like this:

grep my-operator                        1h2m

If your Operator appears in this list, the catalog was successfully parsed and the Operator is now available to install.

Troubleshooting

If it does not appear in this list return to the previous step and check the logs of the catalog pod. If this does not reveal any error messages check the log of both the packageserver pods of OLM in the olm namespace, e.g.:

kubectl get logs packageserver-78c99949df-lf26p -n olm

In some occassions the Operator definition is in the catalog but cannot be understood due to some malformed package/bundle content. This case the packageserver should present a related error message. If there are errors in this log please raise them in the operator-registry issue tracker as any problems caused by malformed bundle/packagemanifest metadata should have been caught during catalog creation.

4. Create an OperatorGroup

An OperatorGroup is used to denote which namespaces your Operator should be watching. It must exist in the namespace where your operator should be deployed, we'll use default in this example. Its configuration depends on whether your Operator supports watching its own namespace, a single other namespace or all namespaces (as indicated by spec.installModes in the CSV).

Create the following file as operator-group.yaml if your Operator supports watching its own or a single namespace.

If your Operator supports watching all namespaces you can skip this step and proceed to creating the Subscription object in the operators namespace. An OperatorGroup already exists there with spec.targetNamespace empty. This kind of OperatorGroup instructs the Operator to watch all namespaces.

apiVersion: operators.coreos.com/v1alpha2
kind: OperatorGroup
metadata:
  name: my-operatorgroup
  namespace: default
spec:
  targetNamespaces:
  - default

Deploy the OperatorGroup resource:

kubectl apply -f operator-group.yaml

5. Create a Subscription

The last steps is to ask OLM to install your Operator. A Subscription is created to represent the intent to install an Operator and keep it updated (automatically even) with newer version from the catalog. This requires you to tell OLM which Operator, in which version from which channel you want to install and where the catalog is, that contains the Operator.

Save the following to a file named: operator-subscription.yaml:

apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: my-operator-subscription
  namespace: default
spec:
  channel: <channel-name>
  name: my-operator
  startingCSV: my-operator.v2.0.0
  source: my-test-catalog
  sourceNamespace: olm

If your Operator supports watching all namespaces, change the namespace of the namespace of the Subscription from default to operators. (This namespace already has an OperatorGroup).

In any case replace <channel-name> with the contents of channel.name in your package.yaml file if you have the packagemanifest format or with the contents from operators.operatorframework.io.bundle.channels.v1 in annotations.yaml if you have the bundle format.

Then create the Subscription:

kubectl apply -f operator-subscription.yaml

Troubleshooting

Note that the Subscription object is not representing your installed Operator (this is the object in the next step). It only intructs OLM to install your Operator and keep it updated (automatically). Any error message in the Subscription status refers to the attempt to install the Operator from the catalog, which is usually caused by incorrect references to the catalog (types in the name of the Operator, catalog, namespace, etc).

6. Verify Operator health

Watch your Operator being deployed by OLM from the catalog with the following command. Change the namespace from default to operators if you installed your Subscrption there. Use the watch switch -w:

$ kubectl get clusterserviceversion -n default -w
NAME                     DISPLAY          VERSION   REPLACES                PHASE
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0      Pending
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0      InstallReady
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0      Installing
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0      Installing
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0      Installing
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0      Installing
my-operator.v2.0.0       My Operator      2.0.0     my-operator.v1.0.0      Succeeded

The ClusterServiceVersion object represents your installed Operator per version. It can take a couple of seconds to be created as part of the Subscription request. There will always be a ClusterServiceVersion in the namespace of the Subscription. If the OperatorGroup was configured to "watch" a list or all namespaces, the ClusterServiceVersion object will be copied to all those namespaces. This might take additional time (usually around 30 secs).

If the above command succeeds and the ClusterServiceVersion has transitioned to the Succeeded phase you will also find your Operator's Deployment(s) in the same namespace where the Subscription is. This is your Operator running:

kubectl get deployment -n default

Troubleshooting

If the ClusterServiceVersion is in a pending or failed state, problems occurred when trying to install the Operator. There are two common sources: the components that make up the Operator and the Operator binary itself.

Problems with the Operator process itself will result in a Deployment that is unhealthy, either due to a crashing Operator pod or other image level problems. In this case debug the Deployment and Operator logs for any error message. Usually there are either bugs in the Operator or insufficient permissions in the RBAC part of the bundle/package metadata which may crash poorly written Operators.

Problems with installing the Operator components can be debugged with the InstallPlan object. It contains a blueprint of the Operator and lists all the Kubernetes resources that are required for the Operator to function. It is automatically created by OLM and linked to the Subscription. If the Subscription created an InstallPlan you can refer to via the status block of the Subscription: .status.InstallPlan contains the name of the InstallPlan object which is always in the same namespace as the Subscription.

kubectl describe subscription my-operator-subscription -n default

...
Status:
...

  Installplan:
    API Version:  operators.coreos.com/v1alpha1
    Kind:         InstallPlan
    Name:         install-2c8lf
    Uuid:         656e2e6b-582a-46e1-867d-4f7e95c24136
  Last Updated:   2020-11-01T19:38:01Z
  State:          AtLatestKnown
Events:           <none>

kubectl describe installplan install-2c8lf -n default

This will likely be a lengthy output due to the content of every component of the Operator returned. However, in the .status block of this object the name and health of every component is displayed. Problems with InstallPlan components usually stem from malformed components, insufficient permissions, collisions with existing objects etc. It usually needs to be corrected at the Operator metadata level.

Testing Operator Deployment on OpenShift

The process to test on OpenShift Container Platform and OKD 4.3 or newer is exactly the same as described above with the exception that OLM is already installed. You can use the same CLI steps to test your Operator but it can however also be done via the UI.

1. Create the CatalogSource

Create a CatalogSource instance in the openshift-marketplace namespace to reference the Operator catalog image that contains your Operator version to test:

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: my-test-catalog
  namespace: openshift-marketplace
spec:
  sourceType: grpc
  image: quay.io/myaccount/my-test-catalog:latest

You can use the OpenShift Console YAML editor for that or deploy the CatalogSource resource on the CLI:

oc apply -f catalog-source.yaml

If you created your test catalog containing all existing community operators, you should delete the default catalog that OLM ships with to avoid a lot of duplicate entries. To do this navigate to Administration on the main navigation bar on the left and select the Cluster Settings item. In this view, select the Global Configuration tab and filter for OperatorHub:

OpenShift Cluster Settings

Click on the OperatorHub item and select the YAML tab. In the YAML editor set the disabled property for the community-catalog to true:

OpenShift OperatorHub Settings

Click Save.

2. Find your Operator in the OperatorHub UI

Go to your OpenShift UI and find your Operator by filtering for the Custom category: Find your Operator in OperatorHub

3. Install your Operator from OperatorHub

To install your Operator simply click its icon and in the proceeding dialog click Install. Install your Operator from OperatorHub You will be asked where to install your Operator. Select either of the desired installation modes, if your Operator supports it and then click Subscribe Install your Operator from OperatorHub You will be forwarded to the Subscription Management section of the OLM UI and after a couple of moments your Operator will be transitioning to Installed. Subscribe to your Operator from OperatorHub

4. Verify Operator health

Change to the Installed Operators section in the left-hand navigation menu to verify your Operator's installation status: See your installed Operator It should have transitioned into the state InstallationSucceeded. You can now test it by starting to use its APIs.

Testing with scorecard

If your Operator is up and running you can verify it is working as intended using its APIs. Additionally you can run operator-sdk's scorecard utility for validating against good practice and correctness of your Operator. Assuming you are still in your top-level directory where my-operator/ is your bundle location following these instructions to test your Operator using the Operator-SDK: Running your Operator with scorecard
