dsoxlab — DevSecOps XL Labs CLI

dsoxlab turns declarative exercises into reproducible, runnable and verifiable environments. A catalog states what it offers through a root meta.yml and one lab.yaml per lab; the engine provisions what each lab asks for, opens it, and proves the result with tests that read the state of the system rather than the commands typed into it.

Nothing about a specific domain lives in the engine: it serves Linux, Ansible, Kubernetes or Terraform labs equally well, and any other catalog that honors the declarative contract. It also scores progress and keeps the history locally, per catalog.

Originally built for the tutorials on blog.stephane-robert.info, and usable without them.

dsoxlab in action: list-labs and show


Install and play, in five minutes

Requires Python 3.11+. Nothing to clone, nothing to build.

uv tool install dsoxlab      # or: pipx install dsoxlab
dsoxlab demo                 # installs a one-lab demonstration catalog
cd ~/.local/share/dsoxlab/demo

dsoxlab course premiers-pas     # the lesson
dsoxlab run premiers-pas        # drops you into the lab's work directory
dsoxlab challenge premiers-pas  # the mission
dsoxlab check premiers-pas      # the tests, and the score

The demonstration lab is about dsoxlab itself, and needs no VM, no container and no Docker: it runs anywhere dsoxlab runs.


Documentation

Three readers, three doors. Every page names its audience in its first lines.

I want to… Read
Install dsoxlab, play labs, understand my score For the learner
Write my own catalog of labs For the catalog author, then the v1 contract field by field
Run the machines the labs need For the trainer
Know where dsoxlab writes on my disk Where dsoxlab writes
See every command Command reference, generated from the CLI

In the terminal, dsoxlab fullhelp prints the whole platform guide, in English or in French.


Why dsoxlab

  • One engine, many catalogs. A single CLI drives every training repository. Add a new domain by writing a meta.yml, not by patching the tool.
  • Validation proves, it does not trust. Labs are graded on the actual state of the system (pytest-testinfra) and, when it matters, on persistence after reboot — the trap that fails RHCSA/LFCS candidates.
  • Two runtimes. A lab runs either in a shell on your own machine, or in a vm provisioned for you. Which backend serves that VM (KVM/libvirt, Incus, Outscale) is the catalog's decision, not the lab's.
  • Progress that sticks, per catalog. Scores, hint costs and history are persisted inside the catalog itself, so two catalogs never mix their histories.
  • Bilingual UX. Every user-facing string ships in English and French (DSOXLAB_LANG=en|fr).

Contributing

git clone https://github.com/stephrobert/dsoxlab.git
cd dsoxlab
uv tool install --editable .

See CONTRIBUTING.md for the development setup, the quality gates and the non-negotiable rules (the engine stays domain-agnostic, every user-facing string goes through _() in both languages).


Security

Security posture is enforced, not aspirational — every workflow is scanned by its own tooling on each push and pull request:

  • Hardened GitHub Actions. Every action is pinned to a full commit SHA, the default token has no permissions (jobs opt into least privilege), and checkout never persists credentials.
  • zizmor statically analyzes the workflows on every PR (ci.yml).
  • Plumber validates the CI/CD against a trust policy (.plumber.yaml) at a 100% compliance threshold, and publishes the score badge (plumber.yml).
  • OpenSSF Scorecard tracks the supply-chain posture (scorecard.yml).
  • PyPI Trusted Publishing (OIDC). Releases carry no long-lived token and ship PEP 740 attestations (release.yml).
  • Pre-commit secret scanning. TruffleHog and private-key detection run locally before every commit (see CONTRIBUTING.md).

To report a vulnerability, follow SECURITY.md.
