uninstall.sh

#!/usr/bin/env bash
#
# Uninstaller for the Docker install (Linux, macOS, WSL). Everything
# Jun created lives either in this folder or in Docker under the
# `omega` compose project, so removal is:
#   1. stop and remove the containers (docker compose down)
#   2. optionally delete the Docker volumes (accounts, chats,
#      settings, downloaded model weights) and images. The state
#      volume is saved to ~/jun-backup-<date>.tar.gz first.
#   3. delete this folder
#
# Docker itself, git and Python are left alone, since they're
# general-purpose tools you may use elsewhere. Your docker group
# membership is left alone too. Remove them with your package
# manager if you want.
#
#   ./uninstall.sh          # interactive
#   ./uninstall.sh -y       # no prompts
#     Stops the stack, deletes the Docker data and this folder.
#
# Add `sudo` in front if you said no to the docker group at install.
