	Apptainer is a container platform. It allows you to create and run containers that package up pieces of software in a way that is portable and reproducible. You can build a container using Apptainer on your laptop, and then run it on many of the largest HPC clusters in the world, local university or company clusters, a single server, in the cloud, or on a workstation down the hall. Your container is a single file, and you don’t have to worry about how to install all the software you need on each different operating system.		Apptainer is a container platform.

	A version of ~~apptainer~~ is ~~available~~ for ~~each year-bucket~~. This ~~means that every year~~ a ~~new version~~ will ~~be available~~.		Since Apptainer is not dependent on specific compilers and toolchains, it is now place inside the '''utilities''' bucket. Inside this bucket, there are two options:

			* Apptainer
			* Apptainer-epel


			The regular '''Apptainer''' module loads the version compiled in Anunna. This is more suitable to containers built with more recent operating systems. For most projects this will be enough.

==Apptainer on Anunna==

A version of apptainer is available for each year-bucket. This means that every year a new version will be available.

One can load apptainer by running the following commands

<pre>module load 2023
module load Apptainer</pre>
