Once Tetrate Istio Distro is downloaded, it can be self-updated to the latest version by running the update command:

While we recommend always using the latest Tetrate Istio Distro, if the user wants to download a different version of Tetrate Istio Distro for testing or other reasons, they could do so with the following command:

export GETISTIO_VERSION=<your_version> ##say 0.5.0 for example
curl -sL | bash

This would overwrite the existing version of Tetrate Istio Distro to the one just downloaded.
