1. Docker repository의 이미지를 singularity이미지로 변경하는 경우
- 사용방법: singularity pull [저장할 이미지명] docker://[docker hub의 이미지명]
- 예제
# singularity pull determinedai/environments:cuda-11.3-pytorch-1.10-tf-2.8-gpu-096d730 \ docker://determinedai/environments:cuda-11.3-pytorch-1.10-tf-2.8-gpu-096d730 |
2. Local docker image 변환하는 경우
- Local docker image save
[root@gnode01 test]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE registry 2.8 0d153fadf70b 5 days ago 24.2MB determinedai/install-validation-tool 0.17.14 1a2573d5e195 10 months ago 1.15GB fluent/fluent-bit 1.6 672c60a7ab2a 2 years ago 78.3MB gcr.io/cadvisor/cadvisor v0.36.0 7414b6ed960c 2 years ago 184MB [root@gnode01 test]# docker save registry:2.8 -o registry.tar |
- 저장한 docker image(예: registry.tar)를 singularity 이미지로 변환
