apptainer run [run options...]
This command will launch an Apptainer container and execute a runscript
if one is defined for that container. The runscript is a metadata file within
the container that contains shell commands. If the file is present (and
executable) then this command will execute that file within the container
automatically. All arguments following the container name will be passed
directly to the runscript.
apptainer run accepts the following container formats:
*.sif Singularity Image Format (SIF). Native to Singularity
(3.0+) and Apptainer (v1.0.0+)
*.sqsh SquashFS format. Native to Singularity 2.4+
*.img ext3 format. Native to Singularity versions < 2.4.
directory/ sandbox format. Directory containing a valid root file
system and optionally Apptainer meta-data.
instance://* A local running instance of a container. (See the instance
library://* A SIF container hosted on a Library (no default)
docker://* A Docker/OCI container hosted on Docker Hub or another
shub://* A container hosted on Singularity Hub.
oras://* A SIF container hosted on an OCI registry that supports
the OCI Registry As Storage (ORAS) specification.

--fusemount= A FUSE filesystem mount specification of the form ': ' - where is 'container' or 'host', specifying where the mount will be performed ('container-daemon' or 'host-daemon' will run the FUSE process detached). is the path to the FUSE executable, plus options for the mount. is the location in the container to which the FUSE mount will be attached. E.g. 'container:sshfs 10.0.0.1:/ /sshfs'. Implies --pid.
-h, --help[=false] help for run
-H, --home="/builddir" a home directory specification. spec can either be a src path or src:dest pair. src is the source path of the home directory outside the container and dest overrides the home directory within the container.

-n, --net[=false] run container in a new network namespace (sets up a bridge network interface by default)
--network="bridge" specify desired network type separated by commas, each network will bring up a dedicated interface inside container
--network-args= specify network arguments to pass to CNI plugins
--no-eval[=false] do not shell evaluate env vars or OCI container CMD/ENTRYPOINT/ARGS
--no-home[=false] do NOT mount users home directory if /home is not the current working directory
--no-https[=false] use http instead of https for docker:// oras:// and library:///... URIs
--no-init[=false] do NOT start shim process with --pid
--no-mount= disable one or more 'mount xxx' options set in apptainer.conf and/or specify absolute destination path to disable a 'bind path' entry
--no-privs[=false] drop all privileges from root user in container)
--no-umask[=false] do not propagate umask to the container, set default 0022 umask

-p, --pid[=false] run container in a new PID namespace
--pids-limit=0 Limit number of container PIDs, use -1 for unlimited
--pwd="" initial working directory for payload process inside the container
--rocm[=false] enable experimental Rocm support
-S, --scratch= include a scratch directory within the container that is linked to a temporary dir (use -W to force location)
