6 singularity-run - Run the user-defined default command within a
7 container
8
12 singularity run [run options...] <container>
13
17 This command will launch a Singularity container and execute a
18 runscript
19 if one is defined for that container. The runscript is a metadata
20 file within
21 the container that contains shell commands. If the file is present
22 (and
23 executable) then this command will execute that file within the
24 container
25 automatically. All arguments following the container name will be
26 passed
27 directly to the runscript.
28 singularity run accepts the following container formats:
31 *.sif Singularity Image Format (SIF). Native to
34 Singularity 3.0+
35 *.sqsh SquashFS format. Native to Singularity 2.4+
38 *.img ext3 format. Native to Singularity versions < 2.4.
41 directory/ sandbox format. Directory containing a valid root
44 file
45 system and optionally Singularity meta-data.
46 instance://* A local running instance of a container. (See the
49 instance
50 command group.)
51 library://* A container hosted on a Library (default
54 ⟨https://cloud.sylabs.io/library)⟩
56 docker://* A container hosted on Docker Hub
59 shub://* A container hosted on Singularity Hub
62 oras://* A container hosted on a supporting OCI registry

69 --add-caps=""
70 a comma separated capability list to add
71 --allow-setuid[=false]
74 allow setuid binaries in container (root only)
75 --app=""
78 set an application to run inside a container
79 --apply-cgroups=""
82 apply cgroups from file for container processes (root only)
83 -B, --bind=[]
86 a user-bind path specification. spec has the format
87 src[:dest[:opts]], where src and dest are outside and inside paths. If
88 dest is not given, it is set equal to src. Mount options ('opts') may
89 be specified as 'ro' (read-only) or 'rw' (read/write, which is the
90 default). Multiple bind paths can be given by a comma separated list.
91 -e, --cleanenv[=false]
94 clean environment before running container
95 -c, --contain[=false]
98 use minimal /dev and empty other directories (e.g. /tmp and $HOME)
99 instead of sharing filesystems from your host
100 -C, --containall[=false]
103 contain not only file systems, but also PID, IPC, and environment
104 --disable-cache[=false]

123 run container in new user namespace as uid 0
124 -h, --help[=false]
127 help for run
128 -H, --home="/builddir"
131 a home directory specification. spec can either be a src path or
132 src:dest pair. src is the source path of the home directory outside
133 the container and dest overrides the home directory within the
134 container.
135 --hostname=""
138 set container hostname
139 -i, --ipc[=false]
142 run container in a new IPC namespace
143 --keep-privs[=false]

150 run container in a new network namespace (sets up a bridge network
151 interface by default)
152 --network="bridge"
155 specify desired network type separated by commas, each network will
156 bring up a dedicated interface inside container
157 --network-args=[]

197 Enter a passphrase for an encrypted contaner
198 --pem-path=""
201 Enter an path to a PEM formated RSA key for an encrypted container
202 -p, --pid[=false]
205 run container in a new PID namespace
206 --pwd=""
209 initial working directory for payload process inside the container
210 -S, --scratch=[]
213 include a scratch directory within the container that is linked to
214 a temporary dir (use -W to force location)
215 --security=[]
218 enable security features (SELinux, Apparmor, Seccomp)
219 -u, --userns[=false]
222 run container in a new user namespace, allowing Singularity to run
223 completely unprivileged on recent kernels. This disables some features
224 of Singularity, for example it only works with sandbox images.
225 --uts[=false]
228 run container in a new UTS namespace
229 --vm[=false]
232 enable VM support
233 --vm-cpu="1"

245 bridge network.
246 --vm-ram="1024"
249 Amount of RAM in MiB to allocate to Virtual Machine (implies --vm)
250 -W, --workdir=""
253 working directory to be used for /tmp, /var/tmp and $HOME (if
254 -c/--contain was also used)
255 -w, --writable[=false]
258 by default all Singularity containers are available as read only.
259 This option makes the file system accessible as read/write.
260 --writable-tmpfs[=false]
263 makes the file system accessible as read-write with non persistent
264 data (with overlay support only)

272 echo "Hello world: "
273 # It runs with our inputs when we run the image
275 $ singularity run /tmp/debian.sif one two three
276 Hello world: one two three
277 # Note that this does the same thing
