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:
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 learn about Red Hat Service Interconnect features after the controller and CRDs are installed. Consider installing Section 2.2, “Using Red Hat packages” on Linux.
Procedure
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.
- Unzip the downloaded file and place the Skupper executable on your PATH.
Verify installation:
skupper version
$ skupper version client version 2.1.1-rh-1Copy to Clipboard Copied! Toggle word wrap Toggle overflow
2.2. Using Red Hat packages
Installing Red Hat packages on Linux makes sure you receive the latest updates to the Skupper CLI.
