apptainer instance run

Run a named instance of the given container image

Synopsis

The instance run command allows you to create a new named instance from an existing container image that will begin running in the background. If a runscript is defined in the container metadata the commands in that script will be executed with the instance run command as well. You can optionally pass arguments to runscript.

NOTE: This command was added to Apptainer significantly later than the other action commands and will not work with older containers. In that case, you may need to rebuild the container.

apptainer instance 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

command group.)

library://* A SIF container hosted on a Library (no default)

docker://* A Docker/OCI container hosted on Docker Hub or another

OCI registry.

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.
