The Caddyfile is reassembled every run, but the WebFinger decision reads
BASE_DOMAIN/REDIRECT_URL from .env, and .env was written only on the first
run. So enabling WebFinger on a re-run was a silent no-op: the operator
answers the apex prompt, and the script prints the green
"[+] No BASE_DOMAIN -- pocket-id only" -- contradicting what they just
typed -- then pulls, restarts and prints DEPLOYED with exit 0.
The failure is invisible at the far end too. Caddy has no site block for the
apex, so it never gets a cert for it and discovery fails with a TLS or
connection error rather than a 404. Nothing warns; the one contradicting
line is a green [+] among docker pull output.
Moving the apex had the squid shape: compose reads the shell environment
first, so the new value served for that run only, and the documented later
`docker compose up -d` fell back to stale .env and reverted it.
Record which of the two keys arrived in the environment BEFORE the ":="
defaults, then write those through with a set_env upsert. Only keys actually
passed are touched: automations.sh drops a blank optional answer, so "blank"
cannot be told apart from "not supplied" and must not be read as "disable".
Since that means the prompt cannot retire WebFinger, the enabled path now
says so and points at the .env edit that can.
Verified: enabling on a re-run lands in .env and appends the block; changing
the apex lands and is logged; passing nothing touches nothing; BASE_DOMAIN
without REDIRECT_URL still dies rather than half-enabling.

Add a reusable iptables baseline that hardens hosts with ICMP + SSH
defaults and lets deployments register the ports they need. INPUT is
deny-by-default (loopback, established, ICMP, SSH on the configured port,
plus registered ports); OUTPUT stays open and FORWARD is left untouched so
Docker container networking is unaffected.
Persistence is native -- no boot hook. Rules are saved and restored by the
distro's own package (iptables/ip6tables on Alpine, iptables-persistent on
Debian, iptables-services on Alma) via the new oslib helpers
install_iptables / fw_save_cmd / fw_enable_restore. The saved ruleset
carries the INPUT->sshguard jump, so brute-force protection survives reboot
without the old sshguard-iptables hook.
A self-contained /usr/local/sbin/firewall-apply rebuilds INPUT from
declarative drop-ins under /etc/firewall/ports.d and runs the native save,
so deployments add a port without needing the repo present:
printf '80/tcp\n443/tcp\n' > /etc/firewall/ports.d/mystack.rule
/usr/local/sbin/firewall-apply
- SSH port read live from sshd_config (custom bastion ports just work);
FW_SSH_SOURCE restricts the source CIDR; FW_ALLOW_PING gates echo
- harden-ssh.sh / harden-jumphost.sh install it when ENABLE_FIREWALL=1
(default) and skip the sshguard-only hook; ENABLE_FIREWALL=0 keeps it
- cloud-init base.yml / jumphost.yml forward the toggle
- the four stack deploy.sh open_web_ports() register 80/443 via the
firewall (ufw/firewalld kept as fallback); Docker-published ports bypass
INPUT, so this is belt-and-braces and self-documenting
- README + cloud-init/README document the mechanism, Docker caveat, and the
`disable` recovery path
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: AUTO_REBOOT=idle reboots only when no SSH active; opt-in
Alpine stable-branch upgrades (ALLOW_RELEASE_UPGRADE)
- cloud-init: generic base/jumphost + per-deployment, which harden SSH by
default on fresh VMs
- pocket-id: optional WebFinger block (BASE_DOMAIN), tag v2.8.0
- headscale: fix oidc.expiry schema for 0.28 so the container starts
- Gitea release workflow on tag (TOKEN_GITEA); repo URLs -> Gitea
- README/LICENSE/.gitignore/.gitattributes (force LF)
