⁠Who uses it and why

Who: System administrators, web developers and anyone who writes scripts that process text, files and data.

Why: Perl is a general-purpose programming language, first built for text manipulation and now used for system administration, web development, network programming and more, with a large collection of third-party modules on CPAN.

Use case: An administrator needs to pull errors out of large server logs every night and mail a summary. A short Perl script reads the logs, matches the lines with regular expressions, counts them per service and writes the report, using modules from CPAN for anything it does not do itself.

About the upstream project, written from its own description: https://www.perl.org/about.html⁠ · https://github.com/Perl/perl5⁠

⁠What you get

Signature, user and attestations below were measured on the published digest sha256:b78aec8dcd91dfbf974515decc21bb0240afd2c7b972a2c2e74358404c2ee2db on 2026-10-28.

• Scan scores — we scan every image we publish every day (an SBOM made with syft, vulnerabilities matched with grype, scored with cerodeo-v1, the rubric ce.rodeo published until 2026-10-26) and record each scan with how its score was derived. This release's first and latest scan: https://readystack.dev/products/perl⁠
• ReadyStack release check — passed at release on 2026-10-28: no fixable critical or high vulnerability (Docker Scout and OSV), a non-root user, SBOM and provenance attached. This is ReadyStack's own test, not a Docker grade; vulnerabilities published since then are in today's result at https://readystack.dev/queue⁠.
• Signed — cosign signature by the ReadyStack release key (fingerprint 04daa92344a52dbc) on this release's index digest sha256:b78aec8dcd91dfbf974515decc21bb0240afd2c7b972a2c2e74358404c2ee2db; verify with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/perl:5.44.0-CE-ubuntu24.04-r1.
• Attestations — An SPDX SBOM and SLSA v1 build provenance are attached to this digest.
• Runs as a non-root user (perl).
• Built from source by ReadyStack.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is 5.44.0-CE-ubuntu24.04-r1 — the release on sale at readystack.dev. Release tags use the pattern <upstream-version>-CE-<base-os>-r<N>; the current one is signed, attested (SBOM + provenance), and is provided under the ReadyStack Agreement⁠.

• Earlier release tags (an older version or revision in the same pattern) are superseded. They stay pullable so existing deployments can pin them, but they are no longer re-graded, and fixes appear only in newer releases: move to the current release. For a superseded release's build kit, ask support.

• Release tags never move, so pulling the same tag again never changes the image. To be offered each new release automatically (a new revision r<N+1>, or a new upstream version), use the ReadyStack Renovate preset: https://readystack.dev/updates.html⁠

• Any tag beginning with internal- is an engineering-pipeline artifact published for build observability. It is unsupported, may change or disappear without notice, and must not be used in production.

# ✓ current release
docker pull readystack/perl:5.44.0-CE-ubuntu24.04-r1

# ✗ unsupported (do not pull)
docker pull readystack/perl:internal-...

This release is signed; verify it with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/perl:5.44.0-CE-ubuntu24.04-r1 (the signature is recorded in the public Sigstore transparency log). Support: [email protected]⁠, as set out in the ReadyStack Agreement⁠.

⁠Deployment

A language runtime image: use it as the FROM base of your own image, or run a script with docker run --rm. It runs no service.

docker run --rm readystack/perl:5.44.0-CE-ubuntu24.04-r1 perl -v
