Installing the istioctl tool

The istioctl tool is a configuration command line utility that allows service operators to debug and diagnose Istio service mesh deployments.

Prerequisites

Use an istioctl version that is the same version as the Istio control plane for the Service Mesh deployment. See Istio Releases for a list of valid releases, including Beta releases.

Procedure

  1. Confirm if you have istioctl installed, and if so which version, by running the following command at the terminal:

    $ istioctl version

  2. Confirm the version of Istio you are using by running the following command at the terminal:

    $ oc get istio

  3. Install istioctl by running the following command at the terminal:

    $ curl -sL https://istio.io/downloadIstioctl | ISTIO_VERSION=<version> sh -

    Replace <version> with the version of Istio you are using.

  4. Put the istioctl directory on path by running the following command at the terminal:

    $ export PATH=$HOME/.istioctl/bin:$PATH

  5. Confirm that the istioctl client version and the Istio control plane version now match (or are within one version) by running the following command at the terminal:

    $ istioctl version

For more information on usage, see the Istioctl documentation.

Note: istioctl install is not supported. The Sail Operator installs Istio.
