9 With this module you can install packages and files.
10
12 pkg "somepkg",
13 ensure => "present";
14 pkg "somepkg",
15 ensure => "latest",
16 on_change => sub {
17 say "package was updated.";
18 service someservice => "restart";
19 };
20 pkg "somepkg",
21 ensure => "absent";
22
24 pkg($package, %options)
25 Since: 0.45
26 Use this resource to install or update a package. This resource will
28 generate reports.
29 pkg "httpd",
31 ensure => "latest", # ensure that the newest version is installed (auto-update)
32 on_change => sub { say "package was installed/updated"; };
33 pkg "httpd",
35 ensure => "absent"; # remove the package
36 pkg "httpd",
38 ensure => "present"; # ensure that some version is installed (no auto-update)
39 pkg "httpd",
41 ensure => "2.4.6"; # ensure that version 2.4.6 is installed
42 pkg "apache-server", # with a custom resource name
44 package => "httpd",
45 ensure => "present";
46 install($type, $data, $options)
48 The install function can install packages (for CentOS, OpenSuSE and
49 Debian) and files.
50 If you need reports, please use the pkg() resource.
52 installing a package (This is only supported on CentOS, OpenSuSE and
54 Debian systems.)
55 task "prepare", "server01", sub {
56 install package => "perl";
57 # or if you have to install more packages.
59 install package => [
60 "perl",
61 "ntp",
62 "dbus",
63 "hal",
64 "sudo",
65 "vim",
66 ];
67 };
68 installing a file
70 This is deprecated since 0.9. Please use File file instead.
71 task "prepare", "server01", sub {
73 install file => "/etc/passwd", {
74 source => "/export/files/etc/passwd",
75 owner => "root",
76 group => "root",
77 mode => 644,
78 };
79 };
80 installing a file and do something if the file was changed.
82 task "prepare", "server01", sub {
83 install file => "/etc/httpd/apache2.conf", {
84 source => "/export/files/etc/httpd/apache2.conf",
85 owner => "root",
86 group => "root",
87 mode => 644,
88 on_change => sub { say "File was modified!"; }
89 };
90 };
91 installing a file from a template.
93 task "prepare", "server01", sub {
94 install file => "/etc/httpd/apache2.tpl", {
95 source => "/export/files/etc/httpd/apache2.conf",
96 owner => "root",
97 group => "root",
98 mode => 644,
99 on_change => sub { say "File was modified!"; },
100 template => {
101 greeting => "hello",
102 name => "Ben",
103 },
104 };
105 };
106 This function supports the following hooks:
108 before This gets executed before everything is done. The return value
110 of this hook overwrite the original parameters of the function-
111 call.
112 before_change
114 This gets executed right before the new package is installed.
115 This hook is only available for package installations. If you
116 need file hooks, you have to use the file() function.
117 after_change
119 This gets executed right after the new package was installed.
120 This hook is only available for package installations. If you
121 need file hooks, you have to use the file() function.
122 after This gets executed right before the install() function returns.
124 remove($type, $package, $options)
126 This function will remove the given package from a system.
127 task "cleanup", "server01", sub {
129 remove package => "vim";
130 };
131 update_system
133 This function does a complete system update.
134 For example apt-get upgrade or yum update.
136 task "update-system", "server1", sub {
138 update_system;
139 };
140 If you want to get the packages that where updated, you can use the
142 on_change hook.
143 task "update-system", "server1", sub {
145 update_system
146 on_change => sub {
147 my (@modified_packages) = @_;
148 for my $pkg (@modified_packages) {
149 say "Name: $pkg->{name}";
150 say "Version: $pkg->{version}";
151 say "Action: $pkg->{action}"; # some of updated, installed or removed
152 }
153 };
154 };
155 Options for update_system
157 update_metadata
159 Set to TRUE if the package metadata should be updated. Since 1.5
160 default to FALSE if possible. Before 1.5 it depends on the package
161 manager.
162 update_package
164 Set to TRUE if you want to update the packages. Default is TRUE.
165 dist_upgrade
167 Set to TRUE if you want to run a dist-upgrade if your distribution
168 supports it. Default is FALSE.
169 installed_packages
171 This function returns all installed packages and their version.
172 task "get-installed", "server1", sub {
174 for my $pkg (installed_packages()) {
176 say "name : " . $pkg->{"name"};
177 say " version: " . $pkg->{"version"};
178 }
179 };
181 is_installed
183 This function tests if $package is installed. Returns 1 if true. 0 if
184 false.
185 task "isinstalled", "server01", sub {
187 if( is_installed("rex") ) {
188 say "Rex is installed";
189 }
190 else {
191 say "Rex is not installed";
192 }
193 };
194 update_package_db
196 This function updates the local package database. For example, on
197 CentOS it will execute yum makecache.
198 task "update-pkg-db", "server1", "server2", sub {
200 update_package_db;
201 install package => "apache2";
202 };
203 repository($action, %data)
205 Add or remove a repository from the package manager.
206 For Debian: If you have no source repository, or if you don't want to
208 add it, just remove the source parameter.
209 task "add-repo", "server1", "server2", sub {
211 repository "add" => "repository-name",
212 url => "http://rex.linux-files.org/debian/squeeze",
213 key_url => "http://rex.linux-files.org/DPKG-GPG-KEY-REXIFY-REPO"
214 distro => "squeeze",
215 repository => "rex",
216 source => 1;
217 };
218 To specify a key from a file use key_file => '/tmp/mykeyfile'.
220 To use a keyserver use key_server and key_id.
222 For ALT Linux: If repository is unsigned, just remove the sign_key
224 parameter.
225 task "add-repo", "server1", "server2", sub {
227 repository "add" => "altlinux-sisyphus",
228 url => "ftp://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus",
229 sign_key => "alt",
230 arch => "noarch, x86_64",
231 repository => "classic";
232 };
233 For CentOS, Mageia and SuSE only the name and the url are needed.
235 task "add-repo", "server1", "server2", sub {
237 repository add => "repository-name",
238 url => 'http://rex.linux-files.org/CentOS/$releasever/rex/$basearch/';
239 };
241 To remove a repository just delete it with its name.
243 task "rm-repo", "server1", sub {
245 repository remove => "repository-name";
246 };
247 You can also use one call to repository to add repositories on multiple
249 platforms:
250 task "add-repo", "server1", "server2", sub {
252 repository add => myrepo => {
253 Ubuntu => {
254 url => "http://foo.bar/repo",
255 distro => "precise",
256 repository => "foo",
257 },
258 Debian => {
259 url => "http://foo.bar/repo",
260 distro => "squeeze",
261 repository => "foo",
262 },
263 CentOS => {
264 url => "http://foo.bar/repo",
265 },
266 };
267 };
268 package_provider_for $os => $type;
270 To set another package provider as the default, use this function.
271 user "root";
273 group "db" => "db[01..10]";
275 package_provider_for SunOS => "blastwave";
276 task "prepare", group => "db", sub {
278 install package => "vim";
279 };
280 This example will install vim on every db server. If the server is a
282 Solaris (SunOS) it will use the blastwave Repositories.
