Docker Resources

Per-cluster resources

Type	Name pattern	Example (`sind create cluster dev`)
Network	`<realm>-<cluster>-net`	`sind-dev-net`
Controller	`<realm>-<cluster>-controller`	`sind-dev-controller`
Submitter	`<realm>-<cluster>-submitter`	`sind-dev-submitter`
Worker	`<realm>-<cluster>-worker-<N>`	`sind-dev-worker-0`
Config volume	`<realm>-<cluster>-config`	`sind-dev-config`
Munge volume	`<realm>-<cluster>-munge`	`sind-dev-munge`
Data volume	`<realm>-<cluster>-data`	`sind-dev-data`

The default realm is sind and the default cluster name is default, resulting in prefixes like sind-default-*. See Realms for custom realm naming.

Global resources (mesh)

Type	Name pattern	Example
Mesh network	`<realm>-mesh`	`sind-mesh`
DNS container	`<realm>-dns`	`sind-dns`
SSH container	`<realm>-ssh`	`sind-ssh`
SSH volume	`<realm>-ssh-config`	`sind-ssh-config`

Volume mounts

Volume	Mount point	Controller	Worker	Submitter
`sind-<cluster>-config`	`/etc/slurm`	rw	ro	ro
`sind-<cluster>-munge`	`/etc/munge`	ro	ro	ro
`sind-<cluster>-data`	`/data`	rw	rw	rw
tmpfs	`/tmp`	configurable	configurable	configurable
tmpfs	`/run`	exec,mode=755	exec,mode=755	exec,mode=755
tmpfs	`/run/lock`	—	—	—

SELinux relabeling (:z) is not used because containers run with --security-opt label=disable. This avoids expensive recursive relabeling of bind-mounted host directories.

-v sind-dev-config:/etc/slurm:rw      # controller
-v sind-dev-config:/etc/slurm:ro      # all others
-v sind-dev-munge:/etc/munge:ro       # all nodes
-v sind-dev-data:/data:rw             # all nodes
--tmpfs /tmp:rw,nosuid,nodev,size=256m  # configurable size

Host path storage

When dataStorage.type: hostPath is specified, the data volume is replaced with a bind mount:

-v /path/on/host:/data:rw

Container labels

sind applies labels to containers for filtering and metadata:

Label	Example	Description
`sind.realm`	`sind`	Realm namespace
`sind.cluster`	`dev`	Cluster name
`sind.role`	`worker`	Node role
`sind.slurm.version`	`25.11.4`	Slurm version
