Upgrade the Greenplum Operator

This topic describes how to install a new version of Pivotal Greenplum for Kubernetes and upgrade a deployed Greenplum Operator resource to the newly-installed version. After you have upgraded the Greenplum Operator resource, you can use it to start and stop any currently-deployed Greenplum clusters; however, you cannot change the configuration of deployed Greenplum clusters until you update them to the newer version as described in Upgrade a Greenplum Cluster.


  • This procedure assumes that you have an existing Greenplum for Kubernetes installation.

  • Before you can install the newer Greenplum for Kubernetes version, ensure that you have installed all required software and prepared your Kubernetes environment as described in Prerequisites.


Follow these steps to upgrade the Greenplum Operator resource:

  1. Download the new Greenplum for Kubernetes software from Pivotal Network. The download file has the name: greenplum-for-kubernetes-<version>.tar.gz.

  2. Go to the directory where you downloaded Greenplum for Kubernetes, and unpack the downloaded software. For example:

    $ cd ~/Downloads
    $ tar xzf greenplum-for-kubernetes-*.tar.gz

    The above command unpacks the distribution into a new directory named greenplum-for-kubernetes-<version>.

  3. Go into the new greenplum-for-kubernetes-<version> directory:

    $ cd ./greenplum-for-kubernetes-*
  4. For Minikube deployments only, ensure that the local docker daemon interacts with the Minikube docker container registry:

    $ eval $(minikube docker-env)

    Note: To undo this docker setting in the current shell, run eval "$(docker-machine env -u)".

  5. Load the new Greenplum Operator Docker image to the Docker registry. For example:

    $ docker load -i ./images/greenplum-operator
    e256c39291c9: Loading layer [==================================================>]  79.69MB/79.69MB
    2250a2616dfd: Loading layer [==================================================>]  352.3kB/352.3kB
    b1e0c363fd12: Loading layer [==================================================>]  37.48MB/37.48MB
    Loaded image: greenplum-operator:v0.7.0
  6. If necessary, load the Greenplum for Kubernetes Docker image to the local Docker registry as well. Check the Release Notes for both the currently-deployed Greenplum for Kubernetes software and for the newer version of the software to which you are upgrading. If the new Greenplum for Kubernetes software provides a newer version of Pivotal Greenplum (for example, if your current deployment uses Pivotal Greenplum 5.13 and the newer version uses Pivotal Greenplum 5.16) then also load the new Greenplum for Kubernetes docker image. For example:

    $ docker load -i ./images/greenplum-for-kubernetes
    644879075e24: Loading layer [==================================================>]  117.9MB/117.9MB
    d7ff1dc646ba: Loading layer [==================================================>]  15.87kB/15.87kB

    2b9cc11f6cfc: Loading layer [==================================================>]  176.6kB/176.6kB
    Loaded image: greenplum-for-kubernetes:v0.7.0
  7. Verify that the Docker images are now available:

    $ docker images "greenplum-*"
    REPOSITORY                 TAG          IMAGE ID            CREATED             SIZE
    greenplum-operator         v0.6.0       c2f5f8af7990        7 weeks ago         216MB
    greenplum-for-kubernetes   v0.6.0       63286a99e24a        7 weeks ago         785MB
    greenplum-operator         v0.7.0       1f2299e10960        28 minutes ago      232MB
    greenplum-for-kubernetes   v0.7.0       1d5b86baf556        30 minutes ago      763MB
  8. (Skip this step if you are using local docker images such as on Minikube.) If you push the Greenplum for Kubernetes docker images to a different container registry:

    1. If you want to push the Greenplum for Kubernetes docker images to a different container registry, set the project name and image repo name and then use Docker to push the images. For example, to push the images to Google Cloud Registry using the current Google Cloud project name:

      $ gcloud auth configure-docker
      $ PROJECT=$(gcloud config list core/project --format='value(core.project)')
      $ IMAGE_REPO="gcr.io/${PROJECT}"
      $ GREENPLUM_IMAGE_NAME="${IMAGE_REPO}/greenplum-for-kubernetes:$(cat ./images/greenplum-for-kubernetes-tag)"
      $ docker tag $(cat ./images/greenplum-for-kubernetes-id) ${GREENPLUM_IMAGE_NAME}
      $ docker push ${GREENPLUM_IMAGE_NAME}
      $ OPERATOR_IMAGE_NAME="${IMAGE_REPO}/greenplum-operator:$(cat ./images/greenplum-operator-tag)"
      $ docker tag $(cat ./images/greenplum-operator-id) ${OPERATOR_IMAGE_NAME}
      $ docker push ${OPERATOR_IMAGE_NAME}
    2. Copy the values yaml file from your existing deployment, or create a new YAML file in the workspace subdirectory as shown below:

      $ touch workspace/operator-values-overrides.yaml
    3. If you pushed the Greenplum Operator and Greenplum Database Docker images to a container registry, add two additional lines to the configuration file to indicate the registry where you pushed the images. For example, if you are using Google Cloud Registry with a project named “gp-kubernetes”, you would add the properties:

      operatorImageRepository: gcr.io/gp-kubernetes/greenplum-operator
      greenplumImageRepository: gcr.io/gp-kubernetes/greenplum-for-kubernetes

      Note: If you did not tag the images with a container registry prefix or project name (for example, if you are using your own local Minikube deployment), then you can skip this step.

  9. Initialize and upgrade helm:

    $ helm init --wait --service-account tiller --upgrade
    $HELM_HOME has been configured at /<path>/.helm.
    Tiller (the Helm server-side component) has been upgraded to the current version.
    Happy Helming!
  10. Delete the existing Greenplum Operator deployment:

    $ helm del --purge greenplum-operator
  11. Use helm to create the new Greenplum Operator release, specifying the YAML configuration file if you created one. For example, to create a new release with the name “greenplum-operator”:

    $ helm install --name greenplum-operator -f workspace/operator-values-overrides.yaml operator/

    If you did not create a YAML configuration file (as in the case with Minikube) omit the -f option:

    $ helm install --name greenplum-operator operator/

    Helm begins installing the new release into the Kubernetes namespace specified in the current Kubernetes context. If you want to install into a different namespace, include the --namespace option in the helm command.

    The command displays the following message and concludes with a link to this documentation:

    greenplum-operator has been installed.
    Please see documentation at:
  12. Use watch kubectl get all -l app=greenplum-operator to monitor the progress of the operator deployment. The deployment is complete when the Greenplum Operator pod is in the Running state. For example:

    $ watch kubectl get all -l app=greenplum-operator
    NAME                                      READY     STATUS    RESTARTS   AGE
    pod/greenplum-operator-77d6dc5f79-wfgkk   1/1       Running   0          1m
    NAME                                            DESIRED   CURRENT   READY     AGE
    replicaset.apps/greenplum-operator-77d6dc5f79   1         1         1         1m

    Note: If you have an existing Greenplum cluster, you will see a message in your operator logs similar to:

    time="2019-01-10T21:57:35Z" level=error msg="add greenplum cluster failed: cannot process AddEvent: cluster already exists with name: my-greenplum"

    This message is expected when the operator starts up with a pre-existing Greenplum cluster; you can safely ignore it.

At this point, you can interact with the Greenplum Operator to deploy new Greenplum clusters, or to start or stop existing Greenplum clusters. Note, however, that you cannot modify the deployment properties of existing Greenplum clusters until those clusters are upgraded to the latest release. See Upgrade a Deployed Greenplum Cluster.
