install-node.sh no longer runs `curl https://rpm.nodesource.com/setup_N.x | bash` (an unverified remote script). `pkg-cache-repos.sh nodesource N` writes the same nodesource-nodejs repo (origin URL in the shipped image, gpgcheck=1) with the signing key committed in keys/pkg-cache/RPM-GPG-KEY-nodesource. With PKG_CACHE the repo goes through the internal cache (https://192.168.1.40/nodesource/, origin as 2nd baseurl) and the RUN restores the origin files at the end. The unused N|Solid repo (18/20/22) is no longer added. pkg-cache-repos.sh + keys/pkg-cache synced byte-identical from cloud-apache-container branch ci/pkg-cache-more-upstreams (canonical).

## pkg-cache-repos.sh — BUILD-TIME ONLY, OPT-IN. Points dnf/apt at the internal
|
|
## package cache (nginx proxy_cache, CT130 "pkg-cache" on the Proxmox cluster)
|
|
## when PKG_CACHE is set; without it the repo files are left alone and builds
|
|
## use the upstream repositories as before.
|
|
##
|
|
## PKG_CACHE=https://192.168.1.40 pkg-cache-repos.sh rpm # AlmaLinux/EPEL/Remi/NodeSource
|
|
## PKG_CACHE=https://192.168.1.40 pkg-cache-repos.sh apt # Ubuntu, Debian, LiteSpeed
|
|
## pkg-cache-repos.sh release-install epel [remi] # GPG-verified release RPMs (EL9/EL10)
|
|
## pkg-cache-repos.sh nodesource MAJOR # NodeSource repo file + pinned key
|
|
## eval "$(pkg-cache-repos.sh go-env)" # GOPROXY via the cache (go.sum/sumdb verified)
|
|
## pkg-cache-repos.sh restore # undo everything above
|
|
##
|
|
## CANONICAL copy: cloud-apache-container/scripts/pkg-cache-repos.sh (docs/pkg-cache.md
|
|
## there). Other repos carry byte-identical copies - change it there first.
|
|
##
|
|
## Every RUN that rewrites must `restore` before it ends: it puts rewritten files
|
|
## back, deletes files this script created, deletes any NEW repo/apt file that
|
|
## still references the cache, then FAILS if any reference is left — so no shipped
|
|
## layer carries the cache's LAN address (images run on hosts that can't reach it).
|
|
##
|
|
## Why: on 2026-10-21 (PHP security release) builds failed on Remi mirrors lagging
|
|
## hours behind origin, Remi's origin timing out over HTTPS, and an EPEL mirror
|
|
## with a broken certificate. The cache fetches from the ORIGINS over HTTPS (with
|
|
## origin/mirror fallbacks and stale-on-error), keeps metadata ~3 minutes and
|
|
## immutable .rpm/.deb files long-term.
|
|
##
|
|
## Integrity (security review 2026-10-21):
|
|
## * PKG_CACHE must be https://. The cache's certificate is issued by the
|
|
## name-constrained "pkg-cache internal CA" (keys/pkg-cache/ca.crt, valid only
|
|
## for 192.168.1.40 / pkg-cache.*). That CA is trusted ONLY by the rewritten
|
|
## repos (dnf sslcacert= bundle, apt per-host CaInfo) and only during the RUN —
|
|
## never added to the system trust store.
|
|
## * gpgcheck=1 is forced on every rewritten repo; repo_gpgcheck=1 on Remi and
|
|
## AlmaLinux, which sign repomd.xml (measured: repomd.xml.asc 200). EPEL
|
|
## publishes no repomd signature (404), so its metadata relies on HTTPS end
|
|
## to end (client->cache->dl.fedoraproject.org/mirrors, all verified).
|
|
## * release-install downloads epel-release / remi-release (from the cache, or
|
|
## from the HTTPS origin without PKG_CACHE), checks the package name, imports
|
|
## the signing keys committed in keys/pkg-cache/ and requires
|
|
## `rpm -K` "signatures OK" before installing with localpkg_gpgcheck=1.
|
|
## * The php.net version gates (EXPECT_PHP_MIN / EXPECT_PHP_VERSION) still fail
|
|
## a build that gets old PHP (replay of old-but-signed metadata).
|
|
##
|
|
## rpm: each rewritten baseurl keeps the upstream origin as a SECOND url, so if
|
|
## the cache dies mid-build dnf fails over to the origin by itself.
|
|
## apt: apt has no per-source failover; CI only sets PKG_CACHE after probing the
|
|
## cache (with the CA), and a build without PKG_CACHE uses upstream sources.
