57_Wolve e7ba68790b Done — the Squid deployment is fully built, wired in, and statically verified on the feat/squid-proxy branch. ## What landed deployments/squid/ (13 files) plus wiring into [automations.sh](automations.sh:51), [README.md](README.md), and [.gitignore](.gitignore). All six approved design decisions are implemented: - **Self-built minimal Alpine image** — apk add squid (ssl-bump compiled in), openssl/tini. [entrypoint.sh](deployments/squid/entrypoint.sh) renders squid.conf and generates the cache policy from the lists at start. - **SSL-bump** peek→splice→bump with [splice-domains.txt](deployments/squid/splice-domains.txt) passthrough. - **Wildcard hostname caching** — leading-dot [cache-domains.txt](deployments/squid/cache-domains.txt) + optional regex; CACHE_ONLY_LISTED boost/allowlist toggle. - **HTML/dynamic storage gate**, with query strings exempt on boosted domains. - **CA lifecycle** — generated on first deploy via the built image, key 0600 on the host, staged to tmpfs for the container, never embedded, git-ignored. - **Deny-by-default http_access + BIND_ADDR pinning** as the real access gate (Docker bypasses INPUT). ## One bug caught & fixed The test of the entrypoint's policy generation showed it emitting ubuntu.com with an **unescaped dot** — the s/\./\\./g double-backslash is sed-implementation-dependent and silently failed. Switched to a [.] character class (ubuntu[.]com), portable across busybox/git-bash, re-embedded, re-audited. ## Verified vs. pending **Verified locally:** bash -n on all scripts, LF endings, launcher parses, embedded archive byte-matches the loose files, and the cache-policy generation produces correct Squid directives in both modes. **Pending a Docker host** (this Windows box has none, as the plan anticipated): the container functional smoke test — build, CA mint, a bumped HTTPS fetch, a TCP_HIT, and a splice check. A few version-sensitive specifics get confirmed there: tls-cert=/tls-key= option names, the security_file_certgen path, busybox install -o/-g, ssl::server_name subdomain matching, and the squid -z flag. (All isolated and easy to adjust if any differ.) ## Commit (for you to GPG-sign) Staged and ready. Per your convention I haven't committed — here's the message: `` feat(squid): add SSL-bump caching forward-proxy deployment New deployments/squid/: an explicit forward proxy with SSL-bump TLS interception (local CA, generated on first deploy) and hostname-targeted static-content caching. Unlike the other stacks it is a forward proxy, not a Caddy/Let's-Encrypt inbound site. - Self-built minimal Alpine image (apk squid ships ssl-bump); entrypoint renders squid.conf and generates the cache policy from the domain lists. - Wildcard hostname caching (cache-domains.txt leading-dot + optional cache-domains.regex); boost vs strict-allowlist toggle (CACHE_ONLY_LISTED). - Storage gate never caches HTML or dynamic content; query strings exempt on boosted domains so versioned static assets still cache. - splice-domains.txt passthrough for pinned/banking domains. - Deny-by-default http_access (TRUSTED_CIDR) + BIND_ADDR pinning; CA key 0600 on host, never embedded, git-ignored. - Wired into automations.sh, README, .gitignore; cloud-init for fresh VMs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> ` `bash git commit -S -F- <<'EOF' <paste message above> EOF ` Want me to **push feat/squid-proxy** once you've committed (you'd open the PR in Gitea), or hold? And if you can point me at a Docker host (or run docker compose build in /srv/squid` after a test deploy), I'll drive the functional smoke test and fix anything the live Squid version flags.
New deployments/squid/: an explicit forward proxy with SSL-bump TLS
interception (local CA, generated on first deploy) and hostname-targeted
static-content caching. Unlike the other stacks it is a forward proxy, not
a Caddy/Let's-Encrypt inbound site.
- Self-built minimal Alpine image (apk squid ships ssl-bump); entrypoint
  renders squid.conf and generates the cache policy from the domain lists.
- Wildcard hostname caching (cache-domains.txt leading-dot + optional
  cache-domains.regex); boost vs strict-allowlist toggle (CACHE_ONLY_LISTED).
- Storage gate never caches HTML or dynamic content; query strings exempt on
  boosted domains so versioned static assets still cache.
- splice-domains.txt passthrough for pinned/banking domains.
- Deny-by-default http_access (TRUSTED_CIDR) + BIND_ADDR pinning; CA key 0600
  on host, never embedded, git-ignored.
- Wired into automations.sh, README, .gitignore; cloud-init for fresh VMs.

# cache-domains.txt
#
# Hostnames to cache aggressively (long TTL + force-cache, overriding
# Cache-Control: private/no-store). One entry per line; a LEADING DOT matches
# the domain and all subdomains (.ubuntu.com matches archive.ubuntu.com,
# security.ubuntu.com, ...). For wildcards INSIDE a label, use
# cache-domains.regex instead.
#
# These are BUMPED (decrypted) so HTTPS bodies can be cached -- do not also
# list them in splice-domains.txt. HTML and dynamic content are still skipped
# even here (see the storage gate); only static objects are stored.
#
# Defaults target high-bandwidth distro / package / container mirrors for a
# fleet of VMs. Trim or extend for your environment.
