Chapter 2. Installing the CLI

The Skupper CLI provides a method to create both Kubernetes and local system sites.

There are two methods to install the CLI:

Note

For Kubernetes, you must install the CRDs and controller using YAML or the Operator before creating sites.

2.1. Downloading binaries

Downloading the Skupper CLI binaries is a quick way to get started with Red Hat Service Interconnect after the controller and CRDs are installed. Consider installing Section 2.2, “Using Red Hat packages” on Linux.

Procedure

  1. Download binary files for your system architecture.

    Choose the latest Version for 2.1 at Software Downloads.

    For a Mac with Apple silicon, use Rosetta 2 and the Skupper CLI for Mac on x86-64 download.

  2. Unzip the downloaded file and place the Skupper executable on your PATH.

  3. Verify installation: 

    $ skupper version
client version                 2.0.0
    Copy to Clipboard Toggle word wrap

2.2. Using Red Hat packages

Installing Red Hat packages on Linux makes sure you receive the latest updates to the Skupper CLI.

Prerequisites

  • Make sure your subscription is activated and your system is registered. For more information about using the Customer Portal to activate your Red Hat subscription and register your system for packages, see Chapter 7, Using your subscription.

Procedure

  1. Use the subscription-manager command to subscribe to the required package repositories. Replace <version> with 2 for the main release stream.

    Red Hat Enterprise Linux 8
    $ sudo subscription-manager repos --enable=service-interconnect-_<version>_-for-rhel-8-<architecture>-rpms
    Copy to Clipboard Toggle word wrap
    Red Hat Enterprise Linux 9
    $ sudo subscription-manager repos --enable=service-interconnect-_<version>_-for-rhel-9-<architecture>-rpms
    Copy to Clipboard Toggle word wrap

    1. Use the yum or dnf command to install the skupper command: 

      $ sudo dnf install skupper-cli
      Copy to Clipboard Toggle word wrap
Note

You can also install skupper-router, which is only necessary for Linux local system sites.
