#!/bin/bash

############################################
#
# Usage: deploy.sh
#
# To deploy AIStore as a next tier cluster to the *already running*
# AIStore cluster set DEPLOY_AS_NEXT_TIER=1.
#
# NOTE: system environment variables are listed in the `env` package.
# See https://github.com/NVIDIA/aistore/blob/main/api/env/README.md
#
# NOTE: by default, configuration files are stored under $HOME/.config/ais/<app-name>
# E.g., $HOME/.config/ais/authn - AuthN config, $HOME/.config/ais/cli - CLI config
# and so on. This rule holds for all AIS "applications" except `aisnode` itself.
# See https://github.com/NVIDIA/aistore/tree/main/cmn/fname for the most updated locations.
