oci.conf(5) Slurm Configuration File oci.conf(5) 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. The file will always be located in the same directory as the slurm.conf. 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 Con- tainer bundle directory. See the section OCI Pattern for details on pattern replacement. Default is unique directory generated in SlurmdSpoolDir. CreateEnvFile=(null|newline|disabled) Create environment file for container. File will have one envi- ronment variable per line if value is "newline". File will have each environment variable terminated by a NUL (aka '\0') if value is "null". If value is "disabled", then the environment file will not be created. Value of "true" is treated as "null" for backwards compatibil- ity. Value of "false" is treated as "disabled" for backwards compatibility. Note: When CreateEnvFile=newline, any environment variables with a newline will be dropped before writing to the environment file. Default is "disabled". DebugFlags Override debug flags during container operations. See debugflags in slurm.conf. Default: (disabled) DisableCleanup Disable removal of the generated files handed to OCI runtime. Default: false DisableHooks Comma separated list of hook types to disable. Default: allow all hooks. EnvExclude Extended regular expression to filter environment before. This allows for excluding variables to avoid unwanted environment variables inside of containers. Example: EnvExclude="^(SLURM_CONF|SLURM_CONF_SERVER)=" Default is not exclude any environment variables. MountSpoolDir Override pattern for path inside of container to mount Contain- erPath. See the section OCI Pattern for details on pattern re- placement. Default: /var/run/slurm/ RunTimeEnvExclude Extended regular expression to filter environment before calling any RunTime* commands. This allows for excluding variables to avoid unwanted inheritance inside of the OCI runtimes. Example: RunTimeEnvExclude="^(SLURM_CONF|SLURM_CONF_SERVER)=" Default is not exclude any environment variables. FileDebug Override default file logging level during container operations. See SlurmdDebug in slurm.conf. Default: (disabled) IgnoreFileConfigJson=(true|false) Ignore the existence of config.json in OCI bundle path and dis- able loading config.json if it is present. 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 Pat- tern 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 multi- ple OCI runtimes to simplify execution of containers. If pro- vided, it will be used in the place of create and start opera- tions. It avoids the need to poll state of the container result- ing in less monitoring overhead. See the section OCI Pattern for details on pattern replacement. Default: (disabled) RunTimeStart Pattern for OCI runtime start operation. See the section OCI Pattern for details on pattern replacement. Default: (disabled) SrunPath Absolute path to srun executable. Default: (search PATH) SrunArgs Additional arguments to pass to srun. Add one SrunArgs entry per argument. Default: (disabled) StdIODebug Override default STDIO logging level during container opera- tions. See SlurmdDebug in slurm.conf. Default: (disabled) SyslogDebug Override default syslog logging level during container opera- tions. See SlurmdSyslogDebug in slurm.conf. Default: (disabled) NOTES OCI container support is disabled if oci.conf does not exist. If dis- abled, any user passing --container will be doing so in a purely advi- sor manner. OCI Pattern All of the OCI patterns will replace the following characters: Replacements: %% Replace as "%". %@ Replace as the command and arguments. Each argument will be en- closed with single quotes and escaped. %b Replace as OCI Bundle Path. %e Replace as path to file containing environment if CreateEn- vFile=true. %j Replace as numeric job id. %m Replace as spool directory of container as patterned by Contain- erPath. If ContainerPath is not configured or ContainerPath con- tains %m, then replace with SlurmdSpoolDir from slurm.conf(5). %n Replace as nodename. %p Replace as PID of first processes forked off. Only for use in RunTimeKill or RunTimeDelete. %r Replace as original path to rootfs. %s Replace as numeric step id. %t Replace as numeric step task id. %u Replace as user name. %U Replace as numeric user id.
