# Reports GitHub Actions cache usage: either grouped by key prefix or for a single prefix.
|
|
# Prefix = first segment of key (before first "-" or "/"). E.g. buildkit-blob-* -> buildkit, vcpkg/xxx -> vcpkg.
|
|
#
|
|
# Requires: gh (GitHub CLI), jq
|
|
# Run from repo root with gh auth login already done (or GITHUB_TOKEN set in CI).
|
|
#
|
|
# Usage: .ci/gh_buildkit_cache_usage.sh [key-prefix]
|
|
# No args: fetch all caches, group by prefix, print table (count + size per prefix) and grand total.
|
|
# One arg: report only caches whose key starts with key-prefix (default: buildkit-blob).
|
|
#
|
|
# Example: .ci/gh_buildkit_cache_usage.sh # all prefixes
|
|
# Example: .ci/gh_buildkit_cache_usage.sh buildkit-blob # single prefix
