DESCRIPTION
apptainer push uploads container images to remote registries including the Sylabs Container Library and OCI-compatible registries. This enables sharing containers with collaborators and deploying containers to production environments.Authentication is required for most registries. Use apptainer remote login to configure credentials before pushing.

-U, --allow-unsigned
Allow pushing unsigned containers (by default a valid signature is required for library:// pushes).-D, --description text
Attach a description to the container (library:// only).--library url
Specify the Container Library URL to push to.--authfile path
Docker-style authentication file for OCI registry credentials (oras://).--no-https
Use HTTP instead of HTTPS for docker://, oras://, and library:// URIs.
INSTALL
