This article mainly explains "how to package the application in Linux to Snap package format". The explanation in this article is simple and clear and easy to learn and understand. Please follow Xiaobian's train of thought to study and learn "how to package the application in Linux to Snap package format".

It is not always easy to distribute applications on Linux. There are different package formats, basic systems, and available libraries, all of which are a headache as distributions are released over and over again. Now, however, we have something simpler: Snap.

Snap is a new way for developers to package their applications, and it brings many advantages over traditional package formats such as .deb, .rpm and so on. Snap is secure and isolated from each other, and the hosting system uses AppArmor-like technologies that are cross-platform and self-sufficient, allowing developers to accurately package the dependencies needed by the application. Sandboxie isolation also enhances security and allows applications and the entire snap-based system to roll back in the event of problems. Snap is indeed the future of Linux application packaging.

It is not difficult to create a snap package. First, you need a basic snap runtime environment that allows your desktop environment to recognize and run snap packages, a tool called snapd, built into all Ubuntu 16.04 systems by default. Then you need to create the snap tool Snapcraft, which can be installed with a simple command:

The code is as follows:

$sudo apt-get install snapcraft

After this environment is installed, you can snap it up.

Snap uses a specific YAML format file, snapcraft.yaml, which defines how the application is packaged and the dependencies it needs. To demonstrate with a simple application, the following YAML file is a practical example of how to snap a moon-buggy game that is provided in the Ubuntu source.

The code is as follows:

Name: moon-buggy

Version: 1.0.51.11

Summary: Drive a car across the moon

Description: |

A simple command-line game where you drive a buggy on the moon

Apps:

Play:

Command: usr/games/moon-buggy

Parts:

Moon-buggy:

Plugin: nil

Stage-packages: [moon-buggy]

Snap:

-usr/games/moon-buggy

Several new concepts have emerged in the above code. The first part is about information about how to make your application available in the store, setting the metadata name, version number, summary, and description of the package. The apps part implements the play command, which points to the location of the moon-buggy executable. The parts section tells snapcraft which plug-ins are needed to build the application and which packages to rely on. All we need in this simple example is from the moon-buggy application itself in the Ubuntu source, and snapcraft takes care of the rest.

Run snapcraft in the same directory as your snapcraft.yaml, and it will create the moon-buggy1.0.51.11amd64.snap package, which can be installed with the following command:

The code is as follows:

$snap install moon-buggy_1.0.51.11_amd64.snap
