Chapter 1. Installing optional RPM packages
When you install MicroShift, you can add optional RPM packages to help manage your deployments. Examples of optional RPMs include those designed to expand your network, add and manage Operators, and manage applications. Use the following procedures to add the packages that you need.
1.1. Installing the GitOps Argo CD manifests from an RPM package Copy linkLink copied to clipboard!
You can use a lightweight version of Red Hat OpenShift GitOps with MicroShift to help manage your applications by installing the microshift-gitops RPM package.
The microshift-gitops RPM package includes the necessary manifests to run core Argo CD.
The Argo CD web console is not available on MicroShift. This process installs basic GitOps functions.
Prerequisites
- You installed MicroShift version 4.16 or later.
- You configured 250MB RAM of additional storage.
Procedure
Enable the GitOps repository with the subscription manager by running the following command:
$ sudo subscription-manager repos --enable=gitops-1.16-for-rhel-9-$(uname -m)-rpmsInstall the MicroShift GitOps package by running the following command:
$ sudo dnf install -y microshift-gitopsTo deploy Argo CD pods, restart MicroShift by running the following command:
$ sudo systemctl restart microshift
Verification
You can verify that your pods are running properly by entering the following command:
$ oc get pods -n openshift-gitopsExample output
NAME READY STATUS RESTARTS AGE argocd-application-controller-0 1/1 Running 0 4m11s argocd-redis-56844446bc-dzmhf 1/1 Running 0 4m12s argocd-repo-server-57b4f896cf-7qk8l 1/1 Running 0 4m12s
1.2. Installing the multiple networks plugin Copy linkLink copied to clipboard!
You can install the MicroShift Multus Container Network Interface (CNI) plugin alongside a new MicroShift installation. If you want to attach additional networks to a pod for high-performance network configurations, install the microshift-multus RPM package.
The MicroShift Multus CNI plugin manifests are included in the MicroShift binary. To enable multiple networks, you can either set the value in the MicroShift config.yaml file to Enabled, or use the configuration snippet in the microshift-multus RPM. Uninstalling the MicroShift Multus CNI is not supported in either case.
Procedure
Install the Multus RPM package by running the following command:
$ sudo dnf install microshift-multusTipIf you create your custom resources (CRs) while you are completing your installation of MicroShift, you can avoid restarting the service to apply them.
Next steps
- Continue with your new MicroShift installation, including any add-ons.
- Create the custom resources (CRs) needed for your MicroShift Multus CNI plugin.
- Configure other networking CNIs as needed.
- After you have finished installing all of the RPMs that you want to include, start the MicroShift service. The MicroShift Multus CNI plugin is automatically deployed.
1.3. Installing the Operator Lifecycle Manager (OLM) from an RPM package Copy linkLink copied to clipboard!
When you install MicroShift, the Operator Lifecycle Manager (OLM) package is not installed by default. You can install the OLM on your MicroShift instance by using an RPM package. OLM helps you install, update, and manage the lifecycle of Kubernetes native applications (Operators) and their associated services running in each MicroShift node.
Procedure
Install the OLM package by running the following command:
$ sudo dnf install microshift-olmTo apply the manifest from the package to an active node, run the following command:
$ sudo systemctl restart microshift
1.4. Installing and enabling MicroShift Observability Copy linkLink copied to clipboard!
You can install MicroShift Observability at any time, including during the initial MicroShift installation. Observability collects and transmits system data for monitoring and analysis, such as performance and usage metrics and error reporting.
Procedure
Install the
microshift-observabilityRPM by entering the following command:$ sudo dnf install microshift-observabilityEnable the
microshift-observabilitysystem service by entering the following command:$ sudo systemctl enable microshift-observabilityStart the
microshift-observabilitysystem service by entering the following command:$ sudo systemctl start microshift-observabilityRestart MicroShift after the initial installation.
$ sudo systemctl restart microshift-observabilityThe installation is successful if there is no output after you start the
microshift-observabilityRPM.
1.5. Installing the Red Hat OpenShift AI RPM Copy linkLink copied to clipboard!
To use AI models in MicroShift deployments, install the Red Hat OpenShift AI (Red Hat OpenShift AI Self-Managed) RPM with a new MicroShift installation. You can also install the RPM on an existing MicroShift instance if you restart the system.
The microshift-ai-model-serving RPM contains manifests that deploy kserve, with the raw deployment mode enabled, and ServingRuntimes objects in the redhat-ods-applications namespace.
Red Hat OpenShift AI is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.
Prerequisites
- The system requirements for installing MicroShift have been met.
- You have root user access to your machine.
-
The OpenShift CLI (
oc) is installed. - You configured your LVM VG with the capacity needed for the PVs of your workload.
- You have the RAM and disk space required for your AI model.
- You configured the required accelerators, hardware, operating system, and MicroShift to provide the resources your model needs.
- Your AI model is ready to use.
Procedure
Install the MicroShift AI-model-serving RPM package by running the following command:
$ sudo dnf install microshift-ai-model-servingAs a root user, restart the MicroShift service by entering the following command:
$ sudo systemctl restart microshiftOptional: Install the release information package by running the following command:
$ sudo dnf install microshift-ai-model-serving-release-infoNoteThe
microshift-ai-model-serving-release-infoRPM contains a JSON file with image references useful for offline procedures or deploying a copy of aServingRuntimecustom resource (CR) to your namespace during a bootc image build.
Verification
Verify that the
kservepod is running in theredhat-ods-applicationsnamespace by entering the following command:$ oc get pods -n redhat-ods-applicationsExample output
NAME READY STATUS RESTARTS AGE kserve-controller-manager-7fc9fc688-kttmm 1/1 Running 0 1h
Next steps
- Create a namespace for your AI model.
- Package your model into an OCI image.
- Configure a model-serving runtime.
- Verify that your model is ready for inferencing.
- Make requests against the model server.
