Restructure around a single entry point (automations.sh) with a Gum wizard and a self-extracting bundle for repo-less installs. Add scripts/oslib.sh so the provisioning scripts (setup-host, harden-ssh, harden-jumphost, sshuser) run on Alpine/Debian/Alma; seed root keys from globals/. - ntfy SSH-login alerts (user, source IP, key, region, jump target) via pam_exec - daily auto-updates with AUTO_REBOOT=idle (reboots only when no SSH active) and opt-in Alpine stable-branch upgrades - generic + per-deployment cloud-init; Gitea release workflow on tag - README/LICENSE/.gitignore/.gitattributes (force LF); repo URLs -> Gitea

|
# deploy.sh -- deploy the webfinger stack (a single Caddy container) on
|
|
# Alpine. Serves /.well-known/webfinger at $BASE_DOMAIN for OIDC discovery
|
|
# and redirects everything else to $REDIRECT_URL.
|
|
#
|
|
# Single-node: runs as root.
|
|
#
|
|
# What this does:
|
|
# 1. Installs docker + docker-cli-compose if missing.
|
|
# 2. Lays down docker-compose.yml, Caddyfile, .env.example in $STACK_DIR.
|
|
# 3. Generates .env on first run; existing .env is never overwritten.
|
|
# 4. Prompts for required values not preset (BASE_DOMAIN, ISSUER_URL,
|
|
# REDIRECT_URL, ACME_EMAIL).
|
|
# 5. Opens TCP 80/443 in UFW if active.
|
|
# 6. Pulls images, brings the stack up, waits for healthchecks.
|
|
#
|
|
# Idempotent: re-run to apply config changes / pull new images.
|
|
#
|
|
# Self-contained: docker-compose.yml, Caddyfile, .env.example are embedded
|
|
# as a base64-encoded tar.gz at the bottom of this file. Rebuild with
|
|
# build.sh after editing the loose source files.
|
|
#
|
|
# Usage:
|
|
# bash deploy.sh # interactive prompts
|
|
# BASE_DOMAIN=example.com ISSUER_URL=https://auth.example.com \
|
|
# REDIRECT_URL=https://example.org ACME_EMAIL=me@example.com \
