NAME

6       slurmrestd - Interface to Slurm via REST API.
7

SYNOPSIS

9       slurmrestd [OPTIONS...] <[host]:port|unix:/path/to/socket>
10

DESCRIPTION

12       slurmrestd  is  REST  API  interface  for  Slurm. It can be used in two
13       modes:
14
15
16       Inetd Mode: slurmrestd will read and write to STDIN and STDOUT. It  can
17       detect if
18              it is connected to a socket or a locally TTY (interactive mode).
19
20
21       Listen Mode: slurmrestd will open a listening socket on each requested
22              host:port pair or UNIX socket.
23
24
25
26       OPTIONS
27
28
29       [host]:port
30              Hostname  and port to listen against. Host may be (IPv4/IPv6) IP
31              or a resolvable  hostname.  Hostnames  are  only  looked  up  at
32              startup  and  do not change for the life of the process. Host is
33              optional; if not provided slurmrestd will listen on all  network
34              interfaces.
35
36       unix:/path/to/socket
37              Listen  on  local  UNIX  socket.  Must have permission to create
38              socket in filesystem.
39
40       -a <authentication plugins>
41              Comma delimited list of authentication plugins to load.  Set  to
42              "list"  to  dump  a  list  of  the  possible  plugins  to  load.
43              Defaults: all builtin supported REST authentication plugins.
44
45       -f <file>
46              Read Slurm configuration from  the  specified  file.  See  NOTES
47              below.
48
49       -g <group id>
50              Change group id (and drop supplemental groups) before processing
51              client request. This should be a  unique  group  with  no  write
52              access or special permissions. Do not set this user to SlurmUser
53              or root.
54
55       -h     Help; print a brief summary of command options.
56
57       -s <OpenAPI plugins to load>
58              Comma delimited list of OpenAPI plugins.  Set to "list" to  dump
59              a  list  of the possible plugins to load.  Defaults: all builtin
60              supported OpenAPI plugins.
61
62       -t <THREAD COUNT>
63              Specify number of threads to use to process client  connections.
64              Ignored in inetd mode. Default: 20
65
66       -u <user id>
67              Change  user id before processing client request. This should be
68              a unique group with no write access or special  permissions.  Do
69              not set this user to SlurmUser or root.
70
71       -v     Verbose  operation.  Multiple  -v's  increase verbosity.  Higher
72              verbosity levels will have significant performance impact.
73
74       -V     Print version information and exit.
