- name: Install Trivy
# Pinned to v0.69.3 (the latest release with published GitHub-release
# tarballs as of writing). Tags exist for v0.58 onwards but several
# mid-range releases skipped publishing assets to the Releases page;
# the install.sh script fetches via GitHub Releases, so picking one
# of those tags makes install bail silently after detecting the
# version. v0.69.3 ships the standard `trivy_<ver>_Linux-64bit.tar.gz`
# asset.
#
# The installer itself is fetched from the same pinned release tag
# (not the mutable `main` branch) and downloaded to a file before
# execution: a malicious or
# accidental change to install.sh on main can't silently execute
# on this CI runner, and `curl -fsSL` makes transport errors fail
# loudly instead of piping an HTML error page into sh.
# Pinned release tarball, verified against a pinned sha256 (from the
# release's checksums.txt) before it is unpacked. install.sh made a
# second, unretried download that failed on runner DNS blips (exit 6);
# curl --retry-all-errors rides those out. Same step as
# LeanerCloud/cloud-commitments-go#669.
