Downloading the Release

Download and prepare for the installation

Istio is installed in its own istio-system namespace and can manage services from all other namespaces.

1. Go to the Istio release page to download the installation file corresponding to your OS. On a macOS or Linux system, you can run the following command to download and extract the latest release automatically:

   $ curl -L https://git.io/getLatestIstio | sh -

2. Move to the Istio package directory. For example, if the package is istio-1.0.6:

   $ cd istio-1.0.6

   The installation directory contains:

   • Installation .yaml files for Kubernetes in install/
   • Sample applications in samples/
   • The istioctl client binary in the bin/ directory. istioctl is used when manually injecting Envoy as a sidecar proxy and for creating routing rules and policies.
   • The istio.VERSION configuration file

3. Add the istioctl client to your PATH environment variable, on a macOS or Linux system:

   $ export PATH=$PWD/bin:$PATH
