#Istioctl tool

Alauda Service Mesh 2 supports istioctl, the official command line utility for the Istio project that includes many diagnostic and debugging utilities.

#Installing the Istioctl tool

Install the istioctl command-line utility to debug and diagnose Istio service mesh deployments.

Prerequisites

• The Alauda Service Mesh 2 Operator is installed and running.
• You have created at least one Istio resource.

Procedure

1. Confirm which version of the Istio resource runs on the installation by running the following command:

   kubectl get istio -ojsonpath="{range .items[*]}{.spec.version}{'\n'}{end}" | sed s/^v// | sort

   If there are multiple Istio resources with different versions, choose the latest version. The latest version is displayed last.

2. Navigate to https://github.com/istio/istio/releases.

3. Locate the appropriate version and os arch from GitHub releases page.

4. Extract the istioctl binary file.

   1. If you are using a Linux operating system, run the following command:

      tar xzf istioctl-<VERSION>-<OS>-<ARCH>.tar.gz

   2. If you are using an Apple Mac operating system, unpack and extract the archive.

   3. If you are using a Microsoft Windows operating system, use the zip software to extract the archive.

5. Move to the uncompressed directory by running the following command:

   cd istioctl-<VERSION>-<OS>-<ARCH>

6. Add the istioctl client to the path by running the following command:

   export PATH=$PWD:$PATH

7. Confirm that the istioctl client version and the Istio control plane version match or are within one version by running the following command:

   istioctl version

   Example output

   client version: 1.20.0
   control plane version: 1.26.3-asm.r0
   data plane version: none
