Upload image to the provided library (default is “cloud.sylabs.io”)
The Singularity push command allows you to upload your sif image to a library of your choosing. It’s always good practice to sign your containers before pushing them to the library. An auth token is required to push to the remote, so you may need to configure if first with ‘singularity remote’.
singularity push [push options...] <image> library://user/collection/container[:tag]
$ singularity push /home/user/my.sif library://user/collection/my.sif:latest
-U, --allow-unsigned do not require a signed container -h, --help help for push --library string the library to push to (default "https://library.sylabs.io")
