# auth-token.sh — Obtain and cache Authentik API token
|
|
#
|
|
# Usage: auth-token.sh [-f] [-q]
|
|
#
|
|
# Returns a valid Authentik API token. Checks in order:
|
|
# 1. Cached token at ~/.cache/mosaic/authentik-token (if valid)
|
|
# 2. Pre-configured token from credentials.json (authentik.token)
|
|
# 3. Fails with instructions to create a token in the admin UI
|
|
#
|
|
# Options:
|
|
# -f Force re-validation (ignore cached token)
|
|
# -q Quiet mode — only output the token
|
|
# -h Show this help
|
|
#
|
|
# Environment variables (or credentials.json):
|
|
# AUTHENTIK_URL — Authentik instance URL
|
|
# AUTHENTIK_TOKEN — Pre-configured API token (recommended)
