This is the first release of SingularityCE 3.8.0, the Community Edition of the Singularity container runtime hosted at https://github.com/sylabs/singularity. Documentation is available at https://sylabs.io/docs/

Changed defaults / behaviours

  • The package name for this release is now singularity-ce. This name is used for the source tarball, output of an rpmbuild, and displayed in --version information.
  • The name of the top level directory in the source tarball from make dist now includes the version string.

New features / functionalities

  • A new overlay command allows creation and addition of writable overlays.
  • Administrators can allow named users/groups to use specific CNI network configurations. Managed by directives in singularity.conf.
  • The build command now honors --nv, --rocm, and --bind flags, permitting builds that require GPU access or files bound in from the host.
  • A library service hostname can be specified as the first component of a library:// URL.
  • Singularity is now relocatable for unprivileged installations only.

Bug Fixes

  • Respect http proxy server environment variables in key operations.
  • When pushing SIF images to oras:// endpoints, work around Harbor & GitLab failure to accept the SifConfigMediaType.
  • Avoid a setfsuid compilation warning on some gcc versions.
  • Fix a crash when silent/quiet log levels used on pulls from shub:// and http(s):// URIs.
  • Wait for dm device to appear when mounting an encrypted container rootfs.

Testing / Development

Testing changes are not generally itemized. However, developers and contributors should note that this release has modified the behavior of make test for ease of use:

  • make test runs limited unit and integration tests that will not require docker hub credentials.
  • make testall runs the full unit/integration/e2e test suite that requires docker credentials to be set with E2E_DOCKER_USERNAME and E2E_DOCKER_PASSWORD environment variables.
