2024年2月21日 · 本文介绍了Singularity的两种主要镜像形式：SIF（Singularity Image Format）和沙盒目录（Sandbox），以及它们之间的转换。 SIF是默认的、安全的分发格式，而沙盒方便开发和调试。

Singularity v3.0 produces immutable images in the Singularity Image File (SIF) format. This ensures reproducible and verifiable images and allows for many extra benefits such as the ability to sign and verify your containers.

This module contains an open source implementation of the Singularity Image Format (SIF) that makes it easy to create complete and encapsulated container environments stored in a single file. Unless otherwise noted, the SIF source files are distributed under the BSD-style license found in the LICENSE.md file.

Share Singularity images through the Cloud Library, as well as pull/push SIF™ images through Singularity CLI. Share Your Awesome Containers! Sylabs offers a library to store your Singularity containers, a remote container build service, and SIF™ signing keystore.

build is the “Swiss army knife” of container creation. You can use it to download and assemble existing containers from external resources like the Container Library and Docker Hub. You can use it to convert containers between the formats supported by Singularity.

2021年8月15日 · 特点: SIF是从Singularity 3.x版本开始引入的默认镜像格式。这是一个单文件格式，包含了容器的全部内容，包括操作系统、应用程序及其依赖项。SIF格式设计为不可变的，以确保安全和可重复性。用途: 由于其不可变性和单文件特性，SIF文件非常适合分发和共享。

2020年4月6日 · So how do I tell if a file with .sif is a real image file without exec it? @xuecangqiuye .simg was often referred in Singularity v2 for squashfs images when SIF format didn't exist, SIF image encapsulate squashfs image as container filesystem along with other data.

SIF is a file format tailored to container images. It allows for the storage of different parts that makes up a container. For example, it may include OS partitions images, user writable sections, DEF files used to create the container, cryptographic signatures for data integrity and authenticity and the design is prepared to integrate other ...

原本Docker镜像挺好用的，但是最近做项目需要用到超算的集群，Docker无法在上面用，需要将Docker镜像转为singularity镜像，所以下面我就来谈谈如何安装singularity工具，并将docker镜像转为singularity镜像，最后运行singularity容器。 sudo apt-get install -y \ . build-essential \ . uuid-dev \ . libgpgme-dev \ . squashfs-tools \ . libseccomp-dev \ wget \ . pkg-config \ git \ . cryptsetup-bin.

Signing containers: If you do want to share container image (.sif) files directly with colleagues or collaborators, how can the people you send an image to be sure that they have received the file without it being tampered with or suffering from corruption during transfer/storage? And how can you be sure that the same goes for any container ...
