如何从dockerfile构建奇异容器 [英] how to build singularity container from dockerfile

问题描述

我想从dockerfile构建奇异容器.

I want to build singularity container from dockerfile.

我已经从Docker Hub提取并运行了Docker镜像，具有奇异之处.

I have pulled and run docker images from docker hub with singularity.

singularity pull docker://ubuntu:latest

我还从奇异配方文件中构建了图像.

I have also build the image from singularity recipe file.

singularity build  cpp.sif singularity_file

但是我想从dockerfile构建奇异映像.

But I want to build singularity image from dockerfile.

任何人都知道该怎么做.有可能吗?

Anyone know how to do it. Is it possible ???

推荐答案

您不能直接从Dockerfile构建 奇异容器，但是可以分两步完成.

You cannot build a singularity container directly from a Dockerfile, but you can do it in a two-step process.

docker build -t local/my_container .
sudo singularity build my_container.sif docker-daemon://local/my_container

使用 docker://my_container 在Docker Hub上查找容器.当您使用 docker-daemon 时，它将查看您本地构建的docker容器.您也可以在奇点定义文件中使用 Bootstrap:docker-daemon .

Using docker://my_container look for the container on Docker Hub. When you use docker-daemon, it looks at your locally built docker containers. You can also use Bootstrap: docker-daemon in a Singularity definition file.
