Caddy runs in its own container on the caddy_net bridge network, so
"localhost" in a Caddyfile site block resolves to Caddy's own
container — never the host, and never a sibling container. That
broke every reverse proxy pointed at a network_mode: host service
(confirmed live with asterisk-do's web admin): once nothing else
(like a forward_auth redirect) intercepted the request first, Caddy
couldn't actually reach the upstream.
- services/caddy.sh: add extra_hosts so host.docker.internal resolves
inside the Caddy container (Linux Docker needs this explicitly —
it's automatic only on Docker Desktop).
- lib/common.sh's configure_caddy_for_service: bare-port upstreams
(its documented "host-network service" case) now target
host.docker.internal instead of localhost.
- services/asterisk-do.sh: its self-contained Caddy block (doesn't go
through configure_caddy_for_service) gets the same fix for local
Caddy, and now correctly targets the droplet's public IP instead of
localhost for the remote-Caddy snippet case, which had the same bug.
services/asterisk.sh needs no direct change — it already goes through
configure_caddy_for_service, so it inherits the fix.
Replaces the y/n "update in place?" prompt in asterisk.sh/asterisk-do.sh
with an explicit r/f/c choice — (r)einstall in place, (f)ull install,
(c)ancel — defaulting to cancel on a bare Enter (or Ctrl-D) instead of
falling through to a destructive full reinstall.
Adds prompt_reinstall_mode to lib/common.sh (plus matching standalone
stubs in both asterisk scripts for when they run without the full repo)
and documents the convention in CLAUDE.md: any service with a persistent
install directory should offer this choice on rerun instead of re-asking
every prompt just to pick up a script fix.
Re-running either installer on an existing install used to re-ask
every prompt (domain, extras, firewall, Authelia) just to pick up a
script fix like the exports mount. Both now detect an existing
docker-compose.yml + .env and offer to update in place instead: only
vendor files and docker-compose.yml are refreshed and the stack is
rebuilt, leaving .env, firewall rules, and Caddy/Authelia config
untouched.
The vendor-copy and docker-compose.yml generation blocks (previously
inline and duplicated between what would have been two near-identical
code paths) are factored into per-file helper functions
(_asterisk_do_refresh_vendor_files/_asterisk_do_write_compose and
_asterisk_refresh_vendor_files/_asterisk_write_compose) so fresh
installs and updates share one copy of the logic instead of drifting
apart — the same problem that caused the /root export path and the
vpn-diagnostics.sh COPY bug to slip through unevenly between the two
services in the first place. Names are per-file since setup.sh sources
every services/*.sh into one process.
The vendor easy-asterisk script hardcodes /root for both export output
and its import file listing, but nothing was mounted there — exports
were being written to the container's ephemeral filesystem and lost on
recreate. Bind-mount ./exports to /root in both asterisk.sh and
asterisk-do.sh so exports/imports land under ~/docker/<service>/exports
on the host.
Confirmed on a real deployment: the template Caddyfile ships with
"admin off" (deliberate — no local API attack surface), which means
`caddy reload` can never work, since it depends on that same admin
endpoint. Every Caddyfile-editing code path was silently failing to
apply changes as a result — `docker logs caddy` showed
"admin endpoint disabled" and the reload command errored, but the
Caddyfile edit itself (which doesn't need the admin API) had already
succeeded, leaving the running config stale until something else
happened to restart the container.
Fixed in the two places that actually matter here: lib/common.sh's
configure_caddy_for_service (used by asterisk.sh and most other
Caddy-fronted services in the full repo) and asterisk-do.sh's own
self-contained Caddy block (both the standalone-bootstrap stub and the
main path). Each now tries the lightweight reload first — harmless,
and still works if a box ever has the admin API enabled — then falls
back to `docker restart caddy` if that fails, rather than leaving an
edited-but-unapplied Caddyfile.
Not fixed: the same duplicated pattern in ~35 other service files that
carry their own standalone-bootstrap copy of this logic. Those only
matter for the rare single-file standalone execution path for each of
those specific services and are unrelated to tonight's actual issue —
out of scope here.
Verified: full regression run on both asterisk.sh and asterisk-do.sh
still completes cleanly end to end.
The 8080->8081 fix from the last commit just moved the collision
risk, not removed it — any hardcoded port can eventually collide with
something else on a box running several services. Both services now
scan for the first genuinely free port starting at 8081 (ss -tlnH
"sport = :$PORT", capped at 100 ports checked) and use whatever they
find — .env, UFW, the DO Cloud Firewall rule, and the Caddy proxy
target all follow the actual chosen port, not a fixed number.
asterisk-do.sh's self-contained Caddy block (unquoted heredoc) reads
the port live. asterisk.sh's README heredoc is quoted (no expansion),
so its generated docs keep the static "8081" default with an added
note to check .env for the real value if it differed — the summary
echo outside that heredoc still reports the live value correctly.
Verified: normal case still lands on 8081; with 8081 deliberately
occupied by another process, both services correctly detect the
collision and fall through to 8082 instead, confirmed via the actual
generated .env in each case.
Real-world failure: CrowdSec's Local API listens on 127.0.0.1:8080 by
default (confirmed against its actual upstream config.yaml), and Easy
Asterisk's web admin also defaults to 8080. Both services in this repo
run with network_mode: host / directly on the host, so whichever one
starts second gets "OSError: [Errno 98] Address already in use" — in
this case CrowdSec (started earlier via the auto-install chain) had
already claimed the port before the web admin tried to start.
Moved the web admin's default to 8081 in both asterisk-do.sh and
asterisk.sh — WEB_ADMIN_PORT in .env, the UFW rule, the DO Cloud
Firewall rule, the Caddy reverse_proxy target, and every doc/summary
reference. 8081 doesn't collide with anything else in either stack
(5060/5061/8088/8089/3478/10000-20000/49152-49252) or with CrowdSec's
LAPI (8080) or Prometheus metrics (6060, localhost-only either way).
Left the vendor files' own internal fallback (WEB_ADMIN_PORT:-8080)
untouched — .env's explicit value overrides it at runtime regardless,
and vendor/ stays pristine per this repo's convention.
Verified: no stray 8080 in any generated .env/docker-compose.yml for
either service after a full install run; the vendor files' own
internal 8080 fallback (never applies here, since .env always sets it
explicitly) is the only remaining occurrence anywhere.
The Dockerfile COPYs scripts/vpn-diagnostics.sh and
scripts/dns-whitelist.sh into the image, but the vendor-file-copying
step in both asterisk.sh and asterisk-do.sh never copied (or
downloaded, in the GitHub-fallback branch) that scripts/ directory —
only Dockerfile, entrypoint.sh, coturn-entrypoint.sh, and the
management script. Every real install hit "docker compose up -d
--build" failing with:
failed to compute cache key: ... "/scripts/dns-whitelist.sh": not found
Confirmed live on a deployed droplet. vendor/easy-asterisk/scripts/
already has both files — this was purely a missed copy step, not a
vendoring gap. Fixed in both files identically (mkdir scripts/, copy
or curl both scripts, chmod +x alongside the existing executables).
Verified at the filesystem level: after a full install run, both
files land in the build context with correct executable permissions,
resolving the exact COPY instructions that were failing. Full
docker build verification wasn't possible in this sandbox (a separate,
unrelated network restriction blocks pulling the ubuntu:24.04 base
image here), but the missing-file root cause is directly fixed.
Real-world failure: configure_caddy_for_service's own domain prompt
defaults to "<subdomain>.${SITE_DOMAIN}", which only equals
$DOMAIN_NAME if SITE_DOMAIN happens to be set to match. In practice
SITE_DOMAIN is never set when this service is run by name (e.g.
`sudo ./setup.sh asterisk-do`), since that path skips setup.sh's own
site-defaults wizard — so the reconstructed default silently came out
wrong/blank, and a user had to guess whether to type the SIP domain or
something else at a bare "Domain [ ]:" prompt.
There's exactly one correct domain for this site block — $DOMAIN_NAME,
the same one already used for SIP — so it's no longer asked for at
all. This inlines the same Caddyfile-writing logic
configure_caddy_for_service uses (backup, dedup check, reload; local
and remote-Caddy modes both preserved) but targets $DOMAIN_NAME
directly. The only remaining question is a plain yes/no to proxy it.
Verified the block-generation logic directly against a real Caddy
directory + domain (produces the exact expected Caddyfile entry), plus
a full end-to-end regression run.
Typing out keyword names (e.g. "netbird backup") was more friction
than necessary. Now a numbered list (1-6), answered as comma-separated
digits with an example shown ("Example: 5,6"), translated internally
back to the same space-separated keyword string every existing
dispatch check (authelia/ntfy/watchtower/wg-easy/netbird/backup) was
already matching against — so none of those call sites needed to
change. Handles spaces after commas and silently ignores invalid
entries rather than erroring. Verified the number-to-keyword mapping
in isolation across normal input, spacing variants, invalid digits,
and blank, plus a full end-to-end regression run.
Naming a service directly (sudo ./setup.sh asterisk-do) bypasses
setup.sh's own first-run base step entirely — essential packages, SSH
key import, disabling password auth. Docker still gets installed
either way (asterisk-do's own require_docker handles that), but the
SSH-hardening part of this setup's security story was silently
skipped on a genuinely fresh droplet unless the user knew to run
`base` separately first.
Checks the same marker setup.sh itself uses for "is base installed"
(command -v ncdu) and offers to run install_base directly if not —
same cross-service-call pattern already used for Caddy/CrowdSec/etc.
Verified end-to-end in a real sandbox run: base actually installed
packages, and execution correctly continued through the rest of the
asterisk-do flow afterward.
Both let the DO droplet lean on services already running on a
homelab instead of duplicating them locally, per the RAM-budget
discussion (Authelia+Redis and a second CrowdSec LAPI+DB add up).
crowdsec.sh: new step lets this agent register against a remote LAPI
(cscli lapi register -u <url>) and disables its own local API server
by removing the api.server block from config.yaml (backed up first;
verified the exact block boundaries against CrowdSec's actual default
config.yaml from upstream before writing the awk removal). Parsers,
scenarios, and the firewall bouncer still run locally regardless —
only banning decisions centralize, and only after the registration is
approved with `cscli machines validate` on the central machine, which
this script can't do since that's a different box. The final restart
step is skipped with an explanation when registration is pending,
instead of showing a misleading "failed to restart" for an expected
state.
asterisk-do.sh: when no local Authelia is installed, the web-admin
Caddy step now offers a remote Authelia option instead, building the
same forward_auth block inline (authelia.sh's shared Caddy snippet
only exists for local installs) targeting either a bare host:port
(e.g. a NetBird mesh IP) or a full https:// URL. Documents that this
couples web-admin availability to the remote instance's reachability,
while SIP/calling on the droplet stays unaffected either way.
Both changes verified: the config.yaml block-removal awk logic tested
against CrowdSec's real upstream default file structure, the remote
Authelia forward_auth block construction tested in isolation, and
full regression runs confirm the default (declined) path through both
new prompts is unchanged.
Adds a 'netbird' keyword to the existing extras prompt, dispatching
services/base.sh's _base_setup_netbird helper — a plain function like
any other once setup.sh sources every services/*.sh file, despite its
underscore-prefixed, not-independently-registered naming. Its own
prompt already defaults to enabling NetBird's built-in SSH server
(--allow-server-ssh), which is what makes the 'backup' extra usable
against a home machine without port-forwarding a router: install
NetBird here and on that machine, join both to the same network, and
Borg's SSH remote target becomes the home machine's mesh IP instead of
a public address. Skips cleanly if NetBird's already installed.
README's Optional extras section documents the pairing.
Extends the self-contained pattern from Caddy/CrowdSec to five more
services, offered through one consolidated "Install:" prompt instead
of five separate interruptions:
- authelia: only offered if Caddy is present (it's useless without
Caddy's forward-auth snippet); dispatched right where Caddy's state
is already known.
- wg-easy: installed alongside the other firewall rules so its port
lands with them. Only 51820/udp (the VPN handshake) goes on the
public firewall — the web UI (51821) is deliberately left closed,
documented as reachable via SSH tunnel instead, since exposing a
VPN's own admin panel publicly is a real foot-gun.
- ntfy, watchtower: independent, dispatched after CrowdSec. Watchtower
section is explicit that it only benefits coturn (a pulled image) —
Asterisk is a local Dockerfile build with no registry tag to check.
- backup (borg-backup): dispatched last. Documented clearly as a
config/data backup to a local machine or SSH remote, not a full
droplet image — the alternative to DO's paid Droplet Backups.
Every sub-install this calls does its own `cd` into ~/docker/<name>;
each call site restores `cd "$EA_DIR"` afterward so the later bare
`docker compose up -d --build` still targets the right directory.
Verified in isolation (mocked cd side effects) since driving five
real interactive sub-installs through piped stdin isn't practical.
README updated with an "Optional extras" section covering all five.
Self-contained by default now: if Caddy or CrowdSec aren't already on
the box, asterisk-do offers to install them itself (calling their
install_ functions directly — setup.sh sources every services/*.sh up
front, so they're already in-process during a wizard run). Standalone
single-file runs get a manual pointer instead, since those functions
don't exist outside the full repo checkout.
Also fixes the confusing "Configure Caddy reverse proxy for Asterisk
Web Admin" domain prompt: it used to ask for a second, independent
domain, which silently breaks the TLS cert sync if it doesn't match
the SIP FQDN exactly (Caddy only holds a cert for the domain it's
actually serving). It now always reuses the SIP FQDN automatically —
reconstructing configure_caddy_for_service's subdomain default so the
common case (SIP domain is a subdomain of SITE_DOMAIN) needs zero
extra input, with clear wording either way. FQDN prompt, README, and
final summary updated to match.
Vendor's logger.conf only sent Asterisk's security-level log lines
(auth failures, SIP registration scanning) to the console, i.e.
Docker's stdout — not a file CrowdSec could tail. asterisk-do.sh now
patches its copy of entrypoint.sh (vendor/ untouched) to also write
those events to /var/log/asterisk/full, which is bind-mounted to
~/docker/asterisk-do/logs/full on the host.
crowdsec.sh now detects that directory and, if present, installs the
crowdsecurity/asterisk collection (asterisk_bf + asterisk_user_enum
scenarios) with a matching log acquisition — mirroring the existing
Caddy detection pattern. Order-independent: asterisk-do's install
summary tells the user to rerun crowdsec if it's already installed,
since detection only runs during crowdsec's own install step.
DigitalOcean doesn't provision swap by default and the $4/mo (512MB)
droplet has little headroom once Docker + Asterisk + coturn are
running. The installer now detects RAM <=2GB with no existing swap and
offers to add a persistent 2GB swapfile before doing anything else, so
that tier is safe to use instead of risking an OOM kill under load.
README updated with the corrected sizing table.
Duplicates services/asterisk.sh (left untouched) into a DO-specific
variant: auto-detects the droplet's public IP/ID via the DO metadata
service, always assumes a public FQDN (no LAN/VLAN prompts), offers to
provision a matching DigitalOcean Cloud Firewall via doctl (never
touching one that's already attached), and documents droplet sizing,
firewall rules, and Sipnetic client setup in the generated README.
