SYNOPSIS

9       auter   [--enable|--disable|--status]   [--prep]  [--apply]  [--reboot]
10       [--postreboot] [--config=<configfile>] [OPTIONS]

DESCRIPTION

13       Automatic Update Transaction Execution by Rackspace. A  wrapper  around
14       cron  and yum/dnf/apt to manage system updates with the ability to con‐
15       figure automatic reboots and custom scripts.
16
17   Actions:
18       --enable
19              Enable auter
20
21       --disable
22              Disable auter. Also deletes unused pidfile if it exists
23
24       --status
25              Show whether enabled or disabled
26
27       --prep Pre-download updates before applying
28
29       --apply
30              Apply updates, and reboot if AUTOREBOOT=yes
31
32       --reboot
33              Reboot system including pre/post reboot scripts
34
35       --postreboot
36              Run post reboot script
37

OPTIONS

39       --config=FILE Specify the full path to an auter config  file.  Defaults
40              to /etc/auter/auter.conf
41
42       --stdout
43              Always log to STDOUT, regardless of not having a tty
44
45       --maxdelay
46              Override MAXDELAY from the command line
47
48       --skip-all-scripts
49
50              Skip   the   executions   of  all  custom  scripts  (Default  in
51              /etc/auter/*.d/)
52
53       --skip-scripts-by-phase=PHASE
54
55              Skip the execution of  the  custom  scripts  for  the  specified
56              phase. You can specify myltiple phases.
57
58              Valid   Phases:   pre-prep,  post-prep,  pre-apply,  post-apply,
59              pre-reboot, post-reboot.

67
68              Example:   --skip-scripts-by-name="10-configsnap-pre,   20-star‐
69              tApp.sh"
70

76
77       -v, --version Show the version
78

DIRECTORIES

80       Default Directory locations are listed below; custom paths can be spec‐
81       ified  in  the  config file. The use of additional, non-default, config
82       files is required when running more than one auter profile.
83
84
85   Pre/Post Hooks
86       If any scripts in the pre/post hook  directories  are  not  executable,
87       they  will  be  skipped  by auter and a warning containing the filename
88       will be logged. If any scripts in the pre/post  hook  directories  exit
89       with a non-zero exit code an error will be logged with the filename and
90       exit code, and auter will abort.
91
92
93       /etc/auter/pre-prep.d
94              Directory containing scripts to be executed  before  downloading
95              updates
96
97
98       /etc/auter/post-prep.d
99              Directory  containing  scripts  to be executed after downloading
100              updates
101
102
103       /etc/auter/pre-apply.d
104              Directory containing scripts to be executed before applying  up‐
105              dates
106
107
108       /etc/auter/post-apply.d
109              Directory  containing  scripts to be executed after applying up‐
110              dates
111
112
113       /etc/auter/pre-reboot.d
114              Directory containing scripts to be executed before rebooting
115
116
117       /etc/auter/post-reboot.d
118              Directory containing scripts to be executed after rebooting
119
120              There is a hard coded delay of 5 minutes  post-reboot  to  allow
121              the  system to become fully ready before the post-reboot scripts
122              are executed.
123
124
125   Hook Execution Order
126       Files in the pre/post script directories are parsed in  sorted  lexical
127       order.  That  is, /etc/auter/pre-apply.d/01_first will be parsed before
128       /etc/auter/pre-apply.d/10_second. Be aware that because the sorting  is
129       lexical,  not  numeric, /etc/auter/pre-apply.d/1_whoops would be loaded
130       after /etc/pre-apply.d/10_second. Using a consistent number of  leading
131       zeroes  in the file names can be used to avoid such problems. For exam‐
132       ple the following execution order would occur for pre-apply scripts:
133
134              pre-apply.d/00-first.sh
135              pre-apply.d/99-second.sh
136              pre-apply.d/AA-fourth.sh
137              pre-apply.d/aa-third.sh
138              pre-apply.d/zz-fifth.sh
139              pre-apply.d/ZZ-sixth.sh
140
141       Note that the ordering is case-insensitive so AA-fourth.sh will be run before aa-third.sh.
142

ENABLE/DISABLE

144       To provide an easy way to switch on/off all auter jobs, use auter --en‐
145       able  or  auter  --disable  to set the lockfile /var/lib/auter/enabled.
146       Auter will check for the presence of this file before running.
147
148       This is also the correct method for cleaning up an unused pidfile.
149

REBOOTING

151       Rebooting is an essential part of applying updates, in order to  ensure
152       the  updated  packages  are in use. An update to the kernel will always
153       need a reboot. Some  application  updates,  for  example  Apache,  will
154       restart  the  service.  However  often  libraries  are updated, such as
155       openssl, which don't force a reboot of services that use them.  Reboot‐
156       ing guarantees that every update is in use by running services. You can
157       either enable AUTOREBOOT=yes in the config file (the default is AUTORE‐
158       BOOT=no),  to  reboot  after  --apply,  or  you can schedule a separate
159       schedule for --reboot via a second cronjob. A 2 minute warning is emit‐
160       ted before the server is rebooted, and this can be cancelled by a supe‐
161       ruser with shutdown -c.
162

EXIT CODES

164        0 = updates successful / no updates available
165        3 = issue related to yum / dnf / apt-get command
166        4 = auter disabled via lockfile
167        5 = script not run as root / DATADIR does not exist / config file does
168       not exist
169        6 = auter is already running / PIDFILE exists
170        7 = yum, dnf or apt-get was not found
171        8 = a pre/post hook exited with a non-zero error code
