The three INFINITO_REGISTRY_CACHE_* variables previously carried their
defaults in compose.yml as `${VAR:-...}`, which baked /tmp paths and
a static 32g cache size into the YAML. Move the defaults into a new
shell module that is sourced via `scripts/meta/env/all.sh` and tighten
compose.yml to require the variables strictly via `${VAR:?...}`.
Why
* Adapt cache size to the host. Hard-coding 32g hurts hosts where
`/tmp` is a small tmpfs (typical Linux: ~half of RAM); the cache
would either be capped above the partition or starve other tmpfs
users. Computing the default as half the free disk space at the
cache path leaves a usable budget for the rest of the system on
small hosts and grows on large ones.
* Single source of values. With defaults in shell, the compose YAML
no longer carries duplicated tunables; `compose.yml` just consumes
what the env layer provides. Same pattern as the existing
INFINITO_CONTAINER strict consumption.
Changes
* New scripts/meta/env/registry_cache.sh exports the three vars.
CACHE_MAX_SIZE = `df --output=avail -B1G "$path" / 2`, walking up to
the closest existing ancestor when the cache path itself does not
exist yet (it is created on first start by `bind:
create_host_path: true`). Minimum 1g, fallback 2g if `df` fails.
* scripts/meta/env/all.sh sources the new module so the Makefile-driven
flow picks it up automatically.
* compose.yml: three `${VAR:-default}` -> `${VAR:?Source scripts/meta/env/registry_cache.sh ...}`
so the absence of the env layer fails fast with a precise message.
* Stale block comment above the registry-cache service (CI-only,
/tmp-defaults, etc.) collapsed to a one-line pointer to the README,
per documentation.md "default to no comments / explain only the
non-obvious why".
* docs/contributing/environment/variables.md and
docs/contributing/artefact/files/compose.yml.md describe the new
defaults source and the half-free-disk computation.
Verified
`bash -c 'source scripts/meta/env/all.sh && docker compose --profile ci --profile cache config'`
resolves the three vars (CACHE_MAX_SIZE: 3g on a host with 7G free
in /tmp). Without sourcing, compose fails with the exact
"Source scripts/meta/env/registry_cache.sh ..." message.
