构建一个安装了SST的CentOS8容器
singularity build –sandbox sst-build docker://centos:8.4.2105
cp sst-*.x86_64.rpm sst-build/home
singularity shell -w sst-build
rpm -ivh /home/sst-*.x86_64.rpm
rm /home/sst-*.x86_64.rpm
exit
singularity build sst.sif sst-build
到节点上升级
singularity shell –writable-tmpfs sst.sif
sst show -ssd
sst load -ssd 0
sst load -ssd 1
……
exit
reboot
