NSENTER(1) User Commands NSENTER(1) 207 208 NAME 209 nsenter - run program with namespaces of other processes 210 211 SYNOPSIS 212 nsenter [options] [program [arguments]] 213 214 DESCRIPTION 215 Enters the namespaces of one or more other processes and then executes the specified program. Enterable namespaces are: 216 217 mount namespace 218 Mounting and unmounting filesystems will not affect the rest of the system (CLONE_NEWNS flag), except for filesystems which are explicitly marked as shared (with 219 mount --make-shared; see /proc/self/mountinfo for the shared flag). 220 221 UTS namespace 222 Setting hostname or domainname will not affect the rest of the system. (CLONE_NEWUTS flag) 223 224 IPC namespace 225 The process will have an independent namespace for System V message queues, semaphore sets and shared memory segments. (CLONE_NEWIPC flag) 226 227 network namespace 228 The process will have independent IPv4 and IPv6 stacks, IP routing tables, firewall rules, the /proc/net and /sys/class/net directory trees, sockets, etc. 229 (CLONE_NEWNET flag) 230 231 PID namespace 232 Children will have a set of PID to process mappings separate from the nsenter process (CLONE_NEWPID flag). nsenter will fork by default if changing the PID 233 namespace, so that the new program and its children share the same PID namespace and are visible to each other. If --no-fork is used, the new program will be 234 exec'ed without forking. 235 236 user namespace 237 The process will have a distinct set of UIDs, GIDs and capabilities. (CLONE_NEWUSER flag) 238 239 See clone(2) for the exact semantics of the flags. 240 241 If program is not given, then ``${SHELL}'' is run (default: /bin/sh). 242 243 OPTIONS 244 -t, --target pid 245 Specify a target process to get contexts from. The paths to the contexts specified by pid are: 246 247 /proc/pid/ns/mnt the mount namespace 248 /proc/pid/ns/uts the UTS namespace 249 /proc/pid/ns/ipc the IPC namespace 250 /proc/pid/ns/net the network namespace 251 /proc/pid/ns/pid the PID namespace 252 /proc/pid/ns/user the user namespace 253 /proc/pid/root the root directory 254 /proc/pid/cwd the working directory respectively 255 256 -m, --mount[=file] 257 Enter the mount namespace. If no file is specified, enter the mount namespace of the target process. If file is specified, enter the mount namespace specified 258 by file. 259 260 -u, --uts[=file] 261 Enter the UTS namespace. If no file is specified, enter the UTS namespace of the target process. If file is specified, enter the UTS namespace specified by 262 file. 263 264 -i, --ipc[=file] 265 Enter the IPC namespace. If no file is specified, enter the IPC namespace of the target process. If file is specified, enter the IPC namespace specified by 266 file. 267 268 -n, --net[=file] 269 Enter the network namespace. If no file is specified, enter the network namespace of the target process. If file is specified, enter the network namespace spec‐ 270 ified by file. 271 272 -p, --pid[=file] 273 Enter the PID namespace. If no file is specified, enter the PID namespace of the target process. If file is specified, enter the PID namespace specified by 274 file. 275 276 -U, --user[=file] 277 Enter the user namespace. If no file is specified, enter the user namespace of the target process. If file is specified, enter the user namespace specified by 278 file. See also the --setuid and --setgid options. 279 280 -G, --setgid gid 281 Set the group ID which will be used in the entered namespace and drop supplementary groups. nsenter(1) always sets GID for user namespaces, the default is 0. 282 283 -S, --setuid uid 284 Set the user ID which will be used in the entered namespace. nsenter(1) always sets UID for user namespaces, the default is 0. 285 286 --preserve-credentials 287 Don't modify UID and GID when enter user namespace. The default is to drops supplementary groups and sets GID and UID to 0. 288 289 -r, --root[=directory] 290 Set the root directory. If no directory is specified, set the root directory to the root directory of the target process. If directory is specified, set the 291 root directory to the specified directory. 292 293 -w, --wd[=directory] 294 Set the working directory. If no directory is specified, set the working directory to the working directory of the target process. If directory is specified, 295 set the working directory to the specified directory. 296 297 -F, --no-fork 298 Do not fork before exec'ing the specified program. By default, when entering a PID namespace, nsenter calls fork before calling exec so that any children will 299 also be in the newly entered PID namespace. 300 301 -Z, --follow-context 302 Set the SELinux security context used for executing a new process according to already running process specified by --target PID. (The util-linux has to be com‐ 303 piled with SELinux support otherwise the option is unavailable.) 304 305 -V, --version 306 Display version information and exit. 307 308 -h, --help 309 Display help text and exit. 310 311 SEE ALSO 312 setns(2), clone(2) 313 314 AUTHORS 315 Eric Biederman ⟨biederm@xmission.com⟩ 316 Karel Zak ⟨kzak@redhat.com⟩ 317 318 AVAILABILITY 319 The nsenter command is part of the util-linux package and is available from Linux Kernel Archive ⟨ftp://ftp.kernel.org/pub/linux/utils/util-linux/⟩. 320 321 util-linux June 2013 NSENTER(1) 322 -->@coder:~$ docker inspect --format "{{ .State.Pid }}" myip 323 unknown shorthand flag: 'm' in -myip 324 See 'docker inspect --help'. 325 -->@coder:~$ sudo docker run -idt ubuntu 326 8cb6ebee1aa1e62cd0cf4c870d210c1033f5e559b950c9121cf597f798bfdf71 327 -->@coder:~$ sudo docker ps 328 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 329 8cb6ebee1aa1 ubuntu "/bin/bash" 7 seconds ago Up 5 seconds jolly_cannon 330 -->@coder:~$ PID=$(sudo docker-pid 8cb6) 331 sudo: docker-pid：找不到命令 332 -->@coder:~$ PID=$(sudo docker -pid 8cb6) 333 unknown shorthand flag: 'p' in -pid 334 See 'docker --help'. 335 336 Usage: docker [OPTIONS] COMMAND 337 338 A self-sufficient runtime for containers 339 340 Options: 341 --config string Location of client config files (default "/home/coder/.docker") 342 -c, --context string Name of the context to use to connect to the daemon (overrides DOCKER_HOST env var and default context set with "docker context use") 343 -D, --debug Enable debug mode 344 -H, --host list Daemon socket(s) to connect to 345 -l, --log-level string Set the logging level ("debug"|"info"|"warn"|"error"|"fatal") (default "info") 346 --tls Use TLS;

However, unlike -nd, --cut-dirs does not lose with 557 subdirectories---for instance, with -nH --cut-dirs=1, a beta/ subdirectory will be placed to xemacs/beta, as one would expect. 558 559 -P prefix 560 --directory-prefix=prefix 561 Set directory prefix to prefix. The directory prefix is the directory where all other files and subdirectories will be saved to, i.e. the top of the retrieval tree. 562 The default is . (the current directory). 563 564 565 [END] 2019/12/5 11:29:32
