From inception as the Singularity project, Apptainer has always been developed with the philosophy of giving users more power. Advances in the Linux kernel have allowed Apptainer developers to take this philosophy to the next level even permitting unprivileged and relocatable installations. In today’s webinar we will discuss the ways that Apptainer gives users the power to get their work done with as little friction as possible, we’ll demo some of the new advances in unprivileged operations, and we’ll discuss security implications of the unprivileged model.
