  • Use the template.rst as the basis of your specification.

  • Attempt to detail each applicable section.

  • If a section does not apply, use N/A, and optionally provide a short explanation.

  • New specs for review should be placed in the approved subfolder of 1.x or 2.x directories (depending on Airship version they primarily belong to), where they will undergo review and approval in Gerrit.

  • Test if the spec file renders correctly in a web-browser by running make docs command and opening doc/build/html/index.html in a web-browser. Ubuntu needs the following packages to be installed:

    apt-get install -y make tox gcc python3-dev
  • Specs that have finished implementation should be moved to the implemented subfolder of respective 1.x or 2.x directories.

Indexing and Categorization

Use of the index directive in reStructuredText for each document provides the ability to generate indexes to more easily find items later. Authors are encouraged to use index entries for their documents to help with discovery.


Document naming standards help readers find specs. For the Airship repository, the following document naming is recommended. The categories listed here are likely incomplete, and may need expansion to cover new cases. It is preferrable to deviate (and hopefully amend the list) than force document names into nonsense categories. Prefer using categories that have previously been used or that are listed here over new categories, but don't force the category into something that doesn't make sense.

Document names should follow a pattern as follows:


Use the following guidelines to determine the category to use for a document:

  1. For new functionality and features, the best choice for a category is to match a functional duty of Airship.

    Parts of the platform that support the definition of a site, including management of the yaml definitions, document authoring and translation, and the collation of source documents.


    Used for the steps related to preparation and deployment of the genesis node of an Airship deployment.


    Those changes to Airflow that provide for the lifecycle of bare metal components of the system - provisioning, maintenance, and teardown. This includes booting, hardware and network configuration, operating system, and other host-level management


    For functionality that is about interfacing with Kubernetes directly, other than the initial setup that is done during genesis.


    Functionality that is related to the deployment or redeployment of workload onto the Kubernetes cluster.


    Changes to existing workflows to provide new functionality and creation of new workflows that span multiple other areas (e.g. baremetal, k8s, software), or those changes that are new arrangements of existing functionality in one or more of those other areas.


    Security, logging, auditing, monitoring, and those things related to site administrative functions of the Airship platform.

  2. For specs that are not feature focused, the component of the system may be the best choice for a category, e.g. shipyard, armada etc... When there are multiple components involved, or the concern is cross cutting, use of airship is an acceptable category.
  3. If the spec is related to the ecosystem Airship is maintained within, an appropriate category would be related to the aspect it is impacting, e.g.: git, docker, zuul, etc...
