apptainer

与image文件进行交互

apptainer pull docker://ghcr.io/apptainer/lolcow
apptainer shell lolcow_latest.sif

查看缓存

singularity cache list -v
singularity cache clean

~/.apptainer/cache缓存的位置

$ echo "Hello from inside the container" > $HOME/hostfile.txt
$ apptainer exec lolcow_latest.sif cat $HOME/hostfile.tx
Hello from inside the container

This example works because hostfile.txt exists in the user’s home directory. By default Apptainer bind mounts /home/$USER, /tmp, and $PWD into your container at runtime.

$ echo "Drink milk (and never eat hamburgers)." > /data/cow_advice.txt
$ apptainer exec --bind /data:/mnt lolcow_latest.sif cat /mnt/cow_advice.txt
Drink milk (and never eat hamburgers).

 cat /data/cow_advice.txt | apptainer exec lolcow_latest.sif cowsay
