NAME
oci.conf - Slurm configuration file for containers.DESCRIPTION
Slurm supports calling OCI compliant runtimes. oci.conf is an ASCII file which defines parameters used by OCI runtime interface.
Parameter names are case insensitive. Any text following a "#" in the configuration file is treated as a comment through the end of that line. Changes to the configuration file take effect upon restart of Slurm daemons.
The following oci.conf parameters are defined to control the behavior of the --container argument of salloc, srun, and sbatch
- ContainerPath
- Override path pattern for placement of the generated OCI Container bundle
directory. See the section OCI Pattern for details on pattern
replacement.
Default is unique directory generated in SlurmdSpoolDir.
-
- CreateEnvFile=(true|false)
- Create environment file for container. File will have one environment variable
per line.
Default is false.
-
- RunTimeCreate
- Pattern for OCI runtime create operation. See the section OCI Pattern
for details on pattern replacement.
Default: (disabled)
-
- RunTimeDelete
- Pattern for OCI runtime delete operation. See the section OCI Pattern
for details on pattern replacement.
Default: (disabled)
-
- RunTimeKill
- Pattern for OCI runtime kill operation. See the section OCI Pattern
for details on pattern replacement.
Default: (disabled)
-
- RunTimeQuery
- Pattern for OCI runtime query operation (also known as state). See the section
OCI Pattern for details on pattern replacement.
Default: (disabled)
-
- RunTimeRun
- Pattern for OCI runtime run operation. This is not provided in the OCI runtime
specification (<=v1.0) but is provided by multiple OCI runtimes to simplify
execution of containers. If provided, it will be used in the place of create
and start operations. It avoids the need to poll state of the container
resulting in less monitoring overhead. See the section OCI Pattern for
details on pattern replacement.
Default: (disabled)
-
- RunTimeStart
- Pattern for OCI runtime statrt operation. See the section OCI Pattern
for details on pattern replacement.
Default: (disabled)
