# bootstrap.sh — enroll a new client into the homelab context system.
|
|
#
|
|
# Usage:
|
|
# curl -fsSL https://git.hubris.network/dtoro/Homelab-Docs/raw/main/bootstrap.sh \
|
|
# | sudo bash
|
|
# curl ... | sudo bash -s -- --with-mcp # also wire Claude's .mcp.json
|
|
# curl ... | sudo bash -s -- --dry-run # show what would happen
|
|
# curl ... | sudo bash -s -- --no-secrets # skip age-key issuance
|
|
#
|
|
# Prerequisites the script verifies:
|
|
# - running as root
|
|
# - OS is Linux or macOS
|
|
# - git, age, sops are installed
|
|
# - at least one mesh (netbird OR tailscale) is connected
|
|
# - this host has an `hosts/<hostname>.yaml` entry in the repo (or refuses)
