首先是下载源码，singularity下载地址：http://singularity.lbl.gov/all-releases
下载到本地之后，解压
tar xvf singularity-2.2.1.tar.gz
mkdir /gensoft/singularity
cd singularity-2.2.1/
./configure
make
make install
到这里其实singularity已经安装完毕，下面是参照官网说明做的一个镜像
BootStrap: yum
OSVersion: 7
MirrorURL: http://mirror.centos.org/centos/7/os/x86_64/
Include: yum
[yhu@master ~]$sudo
[root@7-2 singularity-2.2.1]#singularity shell –contain /tmp/Centos7.img
Singularity: Invoking an interactive shell within container…
Singularity.Centos7.img> id
uid=0(root) gid=0(root) groups=0(root)
Singularity.Centos7.img> ls /
bin dev etc lib lost+found mnt proc run singularity sys usr
boot environment home lib64 media opt root sbin srv tmp var
Singularity.Centos7.img> exit
exit
singularity制作镜像也可以直接从docker的镜像中获取，使用方法如下：
[yhu@master ~]$sudo singularity import /tmp/tensorflow.img docker://tensorflow/tensorflow:latest
tensorflow/tensorflow:latest
Downloading layer: sha256:a3ed95caeb02ffe68cdd9fd84406680ae93d633cb16422d00e8a7c22955b46d4
...
Adding Docker CMD as Singularity runscript...
Bootstrap initialization
No bootstrap definition passed, updating container
Executing Prebootstrap module
Executing Postbootstrap module
Done.
或者
Bootstrap: docker
From: tensorflow/tensorflow:latest
%runscript
exec /usr/bin/python "$@"
%post
echo "Post install stuffs!"
#测试结果
[yhu@master ~]$sudo ./singularity shell /tmp/tensorflow.img
