Introduction

Snapcraft is the universal app store for Linux. The Snapcraft team have created a platform that makes it simple to build and publish your applications, so they run on all major Linux distributions, decoupling application delivery from Linux distribution release cadence. Snapcraft hands direct control of publishing software to developers. No more old applications left sitting in Linux software repositories.

Abstract

Targeting Linux as an application developer is hard, due to the multitude of distributions with differing release cadence and library versions. Discovery of software for Linux users is fragmented; some exists in distribution package repositories, some on project websites, some in Git releases, some in 3rd party or personal package repositories. As an application developer you have a long tail of old versions in use in the wild, but no real insight into how many users are using your software. Complex applications have complex installation instructions that can be a barrier to entry for many users.

This talk introduces Snaps and Snapcraft at a high level and explains the characteristics of Snaps that enable application developers to target all major Linux distributions (past, present, and future) with a single package. We will describe the tooling used to create Snaps and how to automate multi-architecture build and publish pipelines. We will demonstrate how complex installation documentation for multi-component applications will be replaced with one instruction. We will take a look at the metrics available to Snap publishers that provide insight into their audience and how being featured in the Snap Store delivers a measurable increase in user adoption.

Full Description
