Three issues surfaced when running 'make init' on the deployment host
and were fixed in place:
- wakdo_internal network: explicit subnet 192.168.148.0/24 (RFC 1918,
in the free 192.168.144-159 gap). The host's Docker daemon has its
default address pools saturated by other stacks, so auto-allocation
failed. An explicit subnet bypasses the allocator and isolates Wakdo
from neighbour churn.
- wakdo-cron: init: true added so Docker injects tini as PID 1. Without
it, dcron loops on 'setpgid: Operation not permitted' because PID 1
in a container without an init system cannot change process groups
for its children.
- healthz vhost: served as a static file from /usr/local/apache2/htdocs/
instead of a RewriteRule [R=200] that triggered Apache's ErrorDocument
template (and leaked 'internal error' wording into a 200 response).
The file lives outside /var/www/html/ which is bind-mounted at runtime
and would otherwise mask the COPY.
Deliver the full Docker stack for Bloc 5 DevOps (Cr 7.c.3 and 7.c.4):
- docker/apache/ Custom httpd:2.4-alpine with hardened main config,
MPM event tuning and 3 vhosts (healthz, kiosk static,
admin reverse FCGI to wakdo-app:9000). Kiosk vhost
explicitly denies .php to enforce Bloc 1 isolation.
- docker/php-fpm/ Custom php:8.3-fpm-alpine3.20 with pdo_mysql, opcache,
intl, exif, zip and tini for signal handling.
Dynamic pool 3-10 workers listening on TCP 9000.
- docker/cron/ Custom alpine:3.20 with dcron, mariadb-client, gzip.
Nightly mysqldump at 03h00 with 14-day rotation and
512-byte sanity check. Purge and stats jobs templated.
- docker-compose.yml 4 services orchestrated on 2 networks (internal
bridge + external reverse-proxy). 2 named volumes
for DB and uploads, bind-mount for backups.
Traefik labels for 2 routers with HTTPS redirect.
Makefile adds `make backup` (manual dump) and `make backup-ls`.
.gitignore adds /var/ for backup bind-mount path.
docs/journal/2026-04-24--infra-docker.md documents 5 decisions with
alternatives, maps 16 RNCP criteria to artefacts and prepares 6 jury Q&A.
Validated: `docker compose config --quiet` passes. Smoke test deferred
to next session (requires server .env).
