是否可以从 Dockerfile 创建奇点图像？

Question

I have Singularity installed. In my repo I have Dockerfile. I want to create a SIF (Singularity Image) from that Dockerfile. I tried to look the docs and check the docker build option but it does not contain an option for Dockerfile. Is it possible to create a SIF image from Dockerfile? Something like:

Singularity build test.sif Dockerfile 

Answer 1

You cannot build a singularity image from a dockerfile. But you can build a docker image from the dockerfile and then convert that docker image to singularity format.

docker build -t myimg:latest .
sudo singularity build img.sif docker-daemon://myimg:latest
