从本地专用码头注册表创建奇点容器
问题描述:
从Docker镜像创建Singularity图像时,如何在本地不安全的私有注册表中正确引用Docker镜像?从本地专用码头注册表创建奇点容器
Bootstrap: docker
Registry: localhost:5000
From: tensorflow:latest
%runscript
exec /usr/bin/python "[email protected]"
%post
echo "Post install stuffs!"
结果如下:
Executing Prebootstrap module

奇异正在对HTTPS的私有注册的假设
利用奇异2.2.1,使用spec文件尝试。
谢谢, 码头。
P.S.我无法创建“Singularity”标签,因为我没有足够的声望点,但在此帖子中显示它是有意义的。
答
在回答我自己的问题 - 事实证明,我需要做两件事情:
- 明确添加http://与对本地注册表URL
- 前缀泊坞窗映像名称“/ “,这样它不会使用前缀 ”/库/“
例spec文件:
Bootstrap: docker
Registry: http://localhost:5000
From: /tensorflow:latest
%runscript
exec /usr/bin/python "[email protected]"
%post
echo "Post install stuffs!"
