The BASE_IMAGE build arg was being unconditionally overwritten by
composer.py with the decky's distro build_base (debian:bookworm-slim),
turning the conpot container into a bare Debian image with no conpot
installation — hence the silent restart loop.
Two fixes:
1. composer.py: use args.setdefault() so services that pre-declare
BASE_IMAGE in their compose_fragment() win over the distro default.
2. conpot.py: pre-declare BASE_IMAGE=honeynet/conpot:latest in build
args so it always uses the upstream image regardless of decky distro.
Also removed the USER decnet switch from the conpot Dockerfile. The
upstream image already runs as the non-root 'conpot' user; switching to
'decnet' broke pkg_resources because conpot's eggs live under
/home/conpot/.local and are only on sys.path for that user.
Services now print RFC 5424 to stdout; Docker captures via json-file driver.
A new host-side collector (decnet.web.collector) streams docker logs from all
running decky service containers and writes RFC 5424 + parsed JSON to the host
log file. The existing ingester continues to tail the .json file unchanged.
rsyslog can consume the .log file independently — no DECNET involvement needed.
Removes: bind-mount volume injection, _LOG_NETWORK bridge, log_target config
field and --log-target CLI flag, TCP syslog forwarding from service templates.
Each decky base container now receives a set of Linux kernel sysctls
(net.ipv4.ip_default_ttl, net.ipv4.tcp_syn_retries, etc.) tuned to
match the claimed OS family, making nmap OS detection return the
expected OS rather than the Linux host.
- decnet/os_fingerprint.py: OS profile table (linux/windows/bsd/embedded/cisco)
keyed by TTL and TCP tuning knobs
- decnet/archetypes.py: Archetype gains nmap_os field; windows-* → "windows",
printer/iot/industrial → "embedded", rest → "linux"
- decnet/config.py: DeckyConfig gains nmap_os field (default "linux")
- decnet/cli.py: nmap_os resolved from archetype → DeckyConfig in both CLI
and INI build paths
- decnet/composer.py: base container gets sysctls + cap_add: [NET_ADMIN];
service containers inherit via shared network namespace
- tests/test_os_fingerprint.py: 48 new tests covering profiles, compose
injection, archetype coverage, and CLI propagation

Previously --log-file only set DECNET_LOG_FILE inside containers with no
volume mount, so logs were lost on container restart and never visible on
the host. Now generate_compose binds the host log dir to
/var/log/decnet inside every service container so the file appears on
the host as expected.
- composer.py: _resolve_log_file() maps host path → container path;
generate_compose() mkdir's host dir and injects volume + DECNET_LOG_FILE
- tests/test_log_file_mount.py: 9 new tests covering mount format,
env injection, dir creation, and dedup

- HTTP: configurable server_header, response_code, fake_app presets
(apache/nginx/wordpress/phpmyadmin/iis), extra_headers, custom_body,
static files directory mount
- SSH/Cowrie: configurable kernel_version, hardware_platform, ssh_banner,
and users/passwords via COWRIE_USERDB_ENTRIES; switched to build mode
so cowrie.cfg.j2 persona fields and userdb.txt generation work
- SMTP: configurable banner and MTA hostname
- MySQL: configurable version string in protocol greeting
- Redis: configurable redis_version and os string in INFO response
- BYOS: [custom-*] INI sections define bring-your-own Docker services
- Stealth: rename all *_honeypot.py → server.py; replace HONEYPOT_NAME
env var with NODE_NAME across all 22+ service templates and plugins;
strip "honeypot" from all in-container file content
- Config: DeckyConfig.service_config dict; INI [decky-N.svc] subsections;
composer passes service_cfg to compose_fragment
- 350 tests passing (100%)

- Replace hardcoded ALL_SERVICE_NAMES=[5 services] in cli.py with
_all_service_names() pulling dynamically from the plugin registry;
randomize-services now draws from all 25 registered honeypots
- Add build_base field to DistroProfile: apt-compatible image for service
Dockerfiles (ubuntu22/ubuntu20/kali get their own; others fall back to
debian:bookworm-slim since Dockerfiles use apt-get)
- Add build_base to DeckyConfig; propagate from distro in _build_deckies
and _build_deckies_from_ini
- Inject BASE_IMAGE build arg in composer.py for every build-based service
so each decky's containers reflect its assigned distro
- Update all 21 service Dockerfiles: FROM debian:bookworm-slim →
ARG BASE_IMAGE=debian:bookworm-slim / FROM ${BASE_IMAGE}
- Add tests/test_cli_service_pool.py and tests/test_composer.py (306 total)
