474a7fe62dBuildKit's default GC caps the ephemeral cache tier (RUN --mount=type=cache mounts, local context, git checkouts) at a hardcoded 512 MB. Across the 7-distro build matrix that fills instantly and forces re-downloads of system and R packages on every rebuild. Add docker/buildkitd.toml and pass it via --config when creating the docker-container builders (artemis/amd64, gaia/arm64): - cache-mount tier raised 512 MB -> 8 GB, retained 7 days - total cache bounded at 40 GB with 20 GB min-free (safe on the disk-tight Hetzner host, modest on the Mac mini) Limits are absolute rather than percentages because the two hosts differ ~6x in free space. Document the --config flag in the justfile so a future recreate does not silently revert to the 512 MB default.

# Local helpers for build-cran-binaries.

#
|
|
# `rebuild` (re)builds specific versions of a single package on a given OS/arch
|
|
# by dispatching to a remote buildx builder (the build runs there, not locally).
|
|
# Sensitivity is auto-detected: risky packages land in the per-minor slot
|
|
# (contrib/<x.y>/), everything else in the generic slot; the touched index is
|
|
# refreshed so the result is immediately servable.
|
|
#
|
|
# Prerequisites:
|
|
# - buildx builders named `artemis` (amd64) and `gaia` (arm64), created with the
|
|
# docker-container driver (runs BuildKit on the remote host's docker daemon over
|
|
# SSH). The default `remote` driver does NOT work with an ssh:// docker host.
|
|
# Pass --config docker/buildkitd.toml so BuildKit's GC keeps a usable cache
|
|
# (the default caps the cache-mount tier at 512 MB, forcing re-downloads).
|
|
# docker buildx create --name artemis --driver docker-container --config docker/buildkitd.toml ssh://<user@host-amd64>
|
|
# docker buildx create --name gaia --driver docker-container --config docker/buildkitd.toml ssh://<user@host-arm64>
|
|
# - exported secrets: B2_S3_ACCESS_KEY, B2_S3_SECRET_KEY, PGPASS (GITHUB_PAT optional)
|
|
#
|
|
# Overridable (env or `just VAR=… rebuild …`):
|
|
# R_VERSION (default 4.5.3) — selects the R minor → the per-minor slot
|
|
# AMD64_BUILDER / ARM64_BUILDER — buildx builder names
|
|
#
|
|
# Examples:
|
|
# just rebuild alpine 3.23 amd64 rlang 1.1.4 1.1.3
|
|
# just rebuild redhat 10 arm64 data.table 1.15.4
|
|
# R_VERSION=4.4.3 just rebuild ubuntu noble amd64 Rcpp 1.0.12
