Build debian packages

ops2deb

Are you tired of checking if your favorite devops tools are up-to-date? Are you using a debian based GNU/Linux distribution? ops2deb is designed to generate Debian packages for common devops tools such as kubectl, kustomize, helm, ..., but it could be used to package any statically linked application. In short, it consumes a configuration file and outputs .deb packages.

Configuration file

Written in YAML and composed of a list of package blueprints. A blueprint is defined by the following:

Field	Meaning	Default
name	Component name, e.g. kustomize.
version	Application release to package.
homepage	Upstream project homepage.	None
arch	Package architecture.	amd64
revision	Package revistion.	1
summary	Package short description.
description	Package full description.
fetch	A binary to download, and a sha256 checksum. tar.gz, tar.xz, tar and zip (requires unzip) archives are extracted automatically.	Null
script	List of build instructions templated with jinja2 and intepreted with the default shell.	[]
depends	List of package dependencies. Corresponds to Depends entry in debian/control.	[]
recommends	List of package recommended dependencies. Corresponds to Recommends entry in debian/control.	[]
conflicts	List of conflicting packages. Corresponds to Conflicts entry in debian/control.	[]

Example:

- name: kubectl
  version: 1.20.1
  summary: Command line client for controlling a Kubernetes cluster
  description: |
    kubectl is a command line client for running commands against Kubernetes clusters.
  fetch:
    url: https://storage.googleapis.com/kubernetes-release/release/v{{version}}/bin/linux/amd64/kubectl
    sha256: 3f4b52a8072013e4cd34c9ea07e3c0c4e0350b227e00507fb1ae44a9adbf6785
  script:
    - mv kubectl {{src}}/usr/bin/

Dependencies

• Python >= 3.9
• To build debian packages with ops2deb build you need the following packages on your host:

sudo apt install build-essential fakeroot debhelper

Usage example

Install ops2deb in a virtualenv or with pipx

pipx install ops2deb

Then, in a test directory run:

curl https://raw.githubusercontent.com/upciti/ops2deb/main/ops2deb.yml
ops2deb generate
ops2deb build

To check for new releases run:

ops2deb update

ops2deb uses temp directories to cache downloaded binaries and to run build instructions:

tree /tmp/ops2deb_*

The cache can be flushed with:

ops2deb purge

Development

You will need poetry

poetry install
poetry run task check

Important notes

ops2deb DOES NOT sandbox build instructions so if you do something like:

script:
- rm -rf ~/*

You will loose your files... To make sure that you won't mess with your system, run it within a container.
