kevinveenbirkenbachandClaude Opus 4.7 1dd8d3f5c0 feat(compose): add pull-through registry-cache + reorg compose/ subdirs
Introduces a `registry-cache` service (rpardini/docker-registry-proxy) in
the `ci` profile that MITM-caches every outbound docker registry pull
made by `infinito`'s inner dockerd, drastically cutting bandwidth on
re-deploys, parallel CI shards, and local fresh-purges.

Wiring (all bind-mounted via compose.yml, no Dockerfile or entry.sh
staging, so edits hot-reload on next container start):
- CA bundle at /opt/registry-cache-ca (read-only),
- systemd drop-in at /etc/systemd/system/docker.service.d/registry-cache-proxy.conf,
- registry-cache-ca.sh at /usr/local/bin/registry-cache-ca.sh.

The drop-in registers registry-cache-ca.sh as ExecStartPre. Compose
gates `infinito` on `registry-cache` `service_healthy` so the CA is on
disk before dockerd boots; the install script supports both Debian
(`update-ca-certificates`) and Arch/Fedora (`update-ca-trust extract`)
trust stores, detected by command availability.

Also reorganizes compose/ into per-service subdirectories
(compose/coredns/, compose/registry-cache/) with README.md per directory
following the documentation guidelines, adds scripts/docker/README.md,
and nests the registry-cache host paths under /tmp/infinito/core/
(mirror/ for blobs, ca/ for the MITM CA bundle).

Docker Runner Scripts 🐳

Shell helpers that run inside the infinito runner container defined by the top-level compose.yml. They cover container lifecycle (entry, healthcheck) and integration with peer compose services (e.g. the registry-cache pull-through proxy).

Scope 📋

  • This directory MUST contain only scripts that execute inside the infinito container, either as the container entrypoint, as a Docker HEALTHCHECK, or as a systemd unit hook.
  • This directory MUST NOT host host-side tooling. Scripts that run on the developer or CI host belong under their workflow-specific path (for example scripts/tests/, scripts/image/, scripts/meta/).
  • This directory MUST NOT host application logic that belongs to an Ansible role.

Bind-mounted scripts 🔗

A script that is bind-mounted from this directory into a fixed in-container path (see compose.yml) MUST keep its git executable bit, because Docker bind-mounts preserve host file permissions and the in-container caller (systemd, dockerd, the entrypoint) cannot recover from a non-executable mount.

When a new script is added with a bind-mount target, its purpose and in-container target path SHOULD be documented at the call site (the matching compose/<service>/ README, or compose.yml.md).

Distro portability 🌐

A script in this directory MUST work across every distro variant that the runner image is built for (currently Debian, Ubuntu, Arch, Fedora, CentOS). Tool availability differs across these variants, so a script SHOULD branch on command -v <tool> rather than on distro IDs.
