Singularity is a container platform based on the principle of mobility of
|
|
compute, and it is designed for use within HPC clusters. For more info see
|
|
singularity.lbl.gov.
|
|
|
|
To test whether the software functions correctly, you can use `singularity
|
|
selftest`. This is what you would expect to see:
|
|
|
|
~# singularity selftest
|
|
+ sh -c test -f /etc/singularity/singularity.conf (retval=0) OK
|
|
+ test -u /usr/libexec/singularity/bin/action-suid (retval=0) OK
|
|
+ test -u /usr/libexec/singularity/bin/create-suid (retval=0) OK
|
|
+ test -u /usr/libexec/singularity/bin/expand-suid (retval=0) OK
|
|
+ test -u /usr/libexec/singularity/bin/export-suid (retval=0) OK
|
|
+ test -u /usr/libexec/singularity/bin/import-suid (retval=0) OK
|
|
+ test -u /usr/libexec/singularity/bin/mount-suid (retval=0) OK
|
|
|
|
You can also pull a container from Docker Hub to prove full functionality
|
|
(Test was performed on a Raspberry Pi 3, hence the arm32v7 part of the Docker
|
|
link. Make sure you pull an image which is compatible with your hardware.)
|
|
For instance:
|
|
|
|
~# singularity pull docker://arm32v7/debian:latest
|
|
Initializing Singularity image subsystem
|
|
Opening image file: debian-latest.img
|
|
Creating 200MiB image
|
|
Binding image to loop
|
|
Creating file system within image
|
|
Image is done: debian-latest.img
|
|
Docker image path: index.docker.io/arm32v7/debian:latest
|
|
Cache folder set to /home/root/.singularity/docker
