Installing IBM StreamSets

An instance administrator can install IBM StreamSets on IBM Software Hub Version 5.3.

Who needs to complete this task?

Instance administrator To install IBM StreamSets, you must be an instance administrator. An instance administrator has permission to install software in the following projects:

The operators project for the instance

The operators for this instance of IBM StreamSets are installed in the operators project.

In the installation commands, the ${PROJECT_CPD_INST_OPERATORS} environment variable refers to the operators project.

The operands project for the instance

The custom resources for the control plane and IBM StreamSets are installed in the operands project.

In the installation commands, the ${PROJECT_CPD_INST_OPERANDS} environment variable refers to the operands project.

When do you need to complete this task?

Review the following options to determine whether you need to complete this task:

  • If you want to install multiple services at the same time, follow the process in Running a batch installation of solutions and services instead.
  • If you didn't install IBM StreamSets as part of a batch installation, complete this task to add IBM StreamSets to your environment.

    Repeat as needed If you are responsible for multiple instances of IBM Software Hub, you can repeat this task to install more instances of IBM StreamSets on the cluster.

Information you need to complete this task

Review the following information before you install IBM StreamSets:

Version requirements

All of the components that are associated with an instance of IBM Software Hub must be installed at the same release. For example, if the IBM Software Hub control plane is installed at Version 5.3.1, you must install IBM StreamSets at Version 5.3.1.

Environment variables

The commands in this task use environment variables so that you can run the commands exactly as written.

  • If you don't have the script that defines the environment variables, see Setting up installation environment variables.
  • To use the environment variables from the script, you must source the environment variables before you run the commands in this task. For example, run:
    source ./cpd_vars.sh
Security context constraint

IBM StreamSets works with the default Red Hat® OpenShift® Container Platform security context constraint, restricted-v2.

Storage requirements
You must specify storage classes when you install IBM StreamSets. The following storage classes are recommended. However, if you don't use these storage classes on your cluster, ensure that you specify a storage class with an equivalent definition.
Storage Notes Storage classes
OpenShift Data Foundation When you install the service, specify file storage.
  • File storage: ocs-storagecluster-cephfs
IBM Fusion Data Foundation Not supported. Not applicable.
IBM Fusion Global Data Platform Not supported. Not applicable.
IBM Storage Scale Container Native Not supported. Not applicable.
Portworx When you install the service, specify file storage. File storage: portworx-shared-gp3
NFS Not supported. Not applicable.
Amazon Elastic storage When you install the service, specify file storage.

File storage is provided by Amazon Elastic File System.

Before you begin

This task assumes that the following prerequisites are met:

System requirements
This task assumes that the cluster meets the minimum requirements for IBM StreamSets.
Where to find more information
If this task is not complete, see System requirements.
Workstation
This task assumes that the workstation from which you will run the installation is set up as a client workstation and has the following command-line interfaces:
  • IBM Software Hub CLI: cpd-cli
  • OpenShift CLI: oc
  • Helm CLI: helm
Where to find more information
If this task is not complete, see Setting up a client workstation.
Control plane
This task assumes that the IBM Software Hub control plane is installed.
Where to find more information
If this task is not complete, see Installing an instance of IBM Software Hub.
Private container registry
If your environment uses a private container registry (for example, your cluster is air-gapped), this task assumes that the following tasks are complete:
  1. The IBM StreamSets software images are mirrored to the private container registry.
    Where to find more information
    If this task is not complete, see Mirroring images to a private container registry.
  2. The cpd-cli is configured to pull the olm-utils-v4 image from the private container registry.
    Where to find more information
    If this task is not complete, see Pulling the olm-utils-v4 image from the private container registry.
Cluster-scoped resources
This task assumes that the cluster-scoped resources, such as custom resource definitions, cluster roles, and cluster role bindings, exist.
Where to find more information
If this task is not complete, see Creating cluster-scoped resources for the IBM Software Hub platform and services.
Image pull secrets
This task assumes that the secrets that contain the image pull credentials for the instance exist.
Where to find more information
If this task is not complete, see Creating image pull secrets for an instance of IBM Software Hub.

Procedure

Complete the following tasks to install IBM StreamSets:

  1. Installing the service
  2. Validating the installation
  3. What to do next

Installing the service

To install IBM StreamSets:

  1. Log the cpd-cli in to the Red Hat OpenShift Container Platform cluster:
    ${CPDM_OC_LOGIN}
    Remember: CPDM_OC_LOGIN is an alias for the cpd-cli manage login-to-ocp command.
  2. Install the operator and custom resource for IBM StreamSets.

    The command that you run depends on the storage on your cluster.

    cpd-cli manage install-components \
--license_acceptance=true \
--components=streamsets \

--block_storage_class=${STG_CLASS_BLOCK} \
--file_storage_class=${STG_CLASS_FILE} \
--image_pull_prefix=${IMAGE_PULL_PREFIX} \
--image_pull_secret=${IMAGE_PULL_SECRET}

Validating the installation

IBM StreamSets is installed when the install-components command returns:
[SUCCESS]... The install-components command ran successfully

If you want to confirm that the custom resource status is Completed, you can run the cpd-cli manage get-cr-status command:

cpd-cli manage get-cr-status \
--cpd_instance_ns=${PROJECT_CPD_INST_OPERANDS} \
--components=streamsets

What to do next

You must complete Post-installation setup for IBM StreamSets before users can access IBM StreamSets.
