Question

我尝试从dockerhub上的docker图像构建一个奇点图像。

singularity build pcgr.simg docker://sigven/pcgr:0.5.3

然后当我尝试你执行它时：

singularity exec pcgr.simg ls

它给了我这个错误：

ERROR  : Failed to mount image in (read only): Invalid argument
ABORT  : Retval = 255

奇点版本：2.3.1-dist

知道如何解决这个问题吗？

谢谢

P.S。：这是构建期间打印的行

Answer 1

我仍然试图绕着奇点的方式工作（使用Docker经验，奇点有点令人困惑）但我发现通过sudo运行命令可以绕过类似的错误。

仍在阅读其中的含义是......

Answer 2

默认情况下，singuarity挂载/ dev / tmp和$ HOME，但是您正在构建不具有提升特权的不可变映像（ simg ），这意味着在挂载OS目录时您没有root权限，您有几个选项，请修改/etc/singularity/singularity.conf中的配置，以免挂载这些目录或使用sudo创建映像。

sudo singularity build pcgr.simg docker: // sigven / pcgr: 0.5.3

奇点错误：无法挂载图像（只读）：参数无效
