Singularity（二）| 安装singularity工具

以默认安装 Ubuntu 22.04 (jammy) 发行版的 WSL 2 (Windows Subsystem for Linux 2) 为例：

参考：官方快速安装向导

• 安装系统依赖项

  首先在主机上安装开发工具和库，在基于 debian 的系统上，包括 Ubuntu：

  # Ensure repositories are up-to-date
  sudo apt-get update
  # Install debian packages for dependencies
  sudo apt-get install -y \
     wget \
     build-essential \
     libseccomp-dev \
     libglib2.0-dev \
     pkg-config \
     squashfs-tools \
     cryptsetup \
     runc

• 安装 Go

  SingularityCE 是用 Go 语言编写的，建议从官方二进制文件中安装最新版本的 Go。

  参考 Go 安装的官方说明：https://golang.org/dl/

  # Remove any previous Go installation
  sudo rm -rf /usr/local/go
  sudo tar -C /usr/local -xzf go1.20.5.linux-amd64.tar.gz
  # Add /usr/local/go/bin to the PATH environment variable.
  echo 'export PATH=/usr/local/go/bin:$PATH' >> ~/.bashrc && \
  source ~/.bashrc

• 利用 apt 安装 SingularityCE

  从 Github 直接下载 SingularityCE 适用于特定 Linux 发行版的最新版本（singularity-ce_3.11.3-jammy_amd64.deb）后运行：

  # 切换root账号
  sudo su
  # 从本地安装
  apt install ./singularity-ce_3.11.3-jammy_amd64.deb
  # 测试
  singularity help

安装成功后显示：

$ singularity help

Linux container platform optimized for High Performance Computing (HPC) and
Enterprise Performance Computing (EPC)

Usage:
  singularity [global options...]

Description:
  Singularity containers provide an application virtualization layer enabling
  mobility of compute via both application and environment portability. With
  Singularity one is capable of building a root file system that runs on any
  other Linux system where Singularity is installed.

Options:
  -d, --debug              print debugging information (highest verbosity)
  -h, --help               help for singularity
  -q, --quiet              suppress normal output
  -s, --silent             only print errors
  -t, --tokenfile string   path to the file holding your sylabs
                           authentication token (default
                           "/home/david/.singularity/sylabs-token")
  -v, --verbose            print additional information

Available Commands:
  build       Build a new Singularity container
  capability  Manage Linux capabilities on containers
  exec        Execute a command within container
  help        Help about any command
  inspect     Display metadata for container if available
  instance    Manage containers running in the background
  keys        Manage OpenPGP key stores
  pull        Pull a container from a URI
  push        Push a container to a Library URI
  run         Launch a runscript within container
  run-help    Display help for container if available
  search      Search the library
  shell       Run a Bourne shell within container
  sign        Attach cryptographic signatures to container
  test        Run defined tests for this particular container
  verify      Verify cryptographic signatures on container
  version     Show application version

Examples:
  $ singularity help <command>
      Additional help for any Singularity subcommand can be seen by appending
      the subcommand name to the above command.
