Rex::Commands::Pkg - Install/Remove Software packages
With this module you can install packages and files.
pkg "somepkg",
ensure => "present";
pkg "somepkg",
ensure => "latest",
on_change => sub {
say "package was updated.";
service someservice => "restart";
};
pkg "somepkg",
ensure => "absent";
Since: 0.45
Use this resource to install or update a package. This resource will generate reports.
pkg "httpd",
ensure => "latest", # ensure that the newest version is installed (auto-update)
on_change => sub { say "package was installed/updated"; };
pkg "httpd",
ensure => "absent"; # remove the package
pkg "httpd",
ensure => "present"; # ensure that some version is installed (no auto-update)
pkg "httpd",
ensure => "2.4.6"; # ensure that version 2.4.6 is installed
pkg "apache-server", # with a custom resource name
package => "httpd",
ensure => "present";
The install function can install packages (for CentOS, OpenSuSE and Debian) and files.
If you need reports, please use the pkg() resource.
task "prepare", "server01", sub {
install package => "perl";
# or if you have to install more packages.
install package => [
"perl",
"ntp",
"dbus",
"hal",
"sudo",
"vim",
];
};
task "prepare", "server01", sub {
install file => "/etc/passwd", {
source => "/export/files/etc/passwd",
owner => "root",
group => "root",
mode => 644,
};
};
task "prepare", "server01", sub {
install file => "/etc/httpd/apache2.conf", {
source => "/export/files/etc/httpd/apache2.conf",
owner => "root",
group => "root",
mode => 644,
on_change => sub { say "File was modified!"; }
};
};
task "prepare", "server01", sub {
install file => "/etc/httpd/apache2.tpl", {
source => "/export/files/etc/httpd/apache2.conf",
owner => "root",
group => "root",
mode => 644,
on_change => sub { say "File was modified!"; },
template => {
greeting => "hello",
name => "Ben",
},
};
};
This function supports the following hooks:
The return value of this hook overwrites the original parameters of the function-call.
This hook is only available for package installations. If you need file hooks, you have to use the file() function.
This hook is only available for package installations. If you need file hooks, you have to use the file() function.
This function will remove the given package from a system.
task "cleanup", "server01", sub {
remove package => "vim";
};
This function does a complete system update.
For example apt-get upgrade or yum update.
task "update-system", "server1", sub {
update_system;
};
If you want to get the packages that where updated, you can use the on_change hook.
task "update-system", "server1", sub {
update_system
on_change => sub {
my (@modified_packages) = @_;
for my $pkg (@modified_packages) {
say "Name: $pkg->{name}";
say "Version: $pkg->{version}";
say "Action: $pkg->{action}"; # some of updated, installed or removed
}
};
};
Options for update_system
This function returns all installed packages and their version.
task "get-installed", "server1", sub {
for my $pkg (installed_packages()) {
say "name : " . $pkg->{"name"};
say " version: " . $pkg->{"version"};
}
};
This function tests if $package is installed. Returns 1 if true. 0 if false.
task "isinstalled", "server01", sub {
if( is_installed("rex") ) {
say "Rex is installed";
}
else {
say "Rex is not installed";
}
};
This function updates the local package database. For example, on CentOS it will execute yum makecache.
task "update-pkg-db", "server1", "server2", sub {
update_package_db;
install package => "apache2";
};
Add or remove a repository from the package manager.
For Debian: If you have no source repository, or if you don't want to add it, just remove the source parameter.
task "add-repo", "server1", "server2", sub {
repository "add" => "repository-name",
url => "http://rex.linux-files.org/debian/squeeze",
key_url => "http://rex.linux-files.org/DPKG-GPG-KEY-REXIFY-REPO"
distro => "squeeze",
repository => "rex",
source => 1;
};
To specify a key from a file use key_file => '/tmp/mykeyfile'.
To use a keyserver use key_server and key_id.
For ALT Linux: If repository is unsigned, just remove the sign_key parameter.
task "add-repo", "server1", "server2", sub {
repository "add" => "altlinux-sisyphus",
url => "ftp://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus",
sign_key => "alt",
arch => "noarch, x86_64",
repository => "classic";
};
For CentOS, Mageia and SuSE only the name and the url are needed.
task "add-repo", "server1", "server2", sub {
repository add => "repository-name",
url => 'http://rex.linux-files.org/CentOS/$releasever/rex/$basearch/';
};
To remove a repository just delete it with its name.
task "rm-repo", "server1", sub {
repository remove => "repository-name";
};
You can also use one call to repository to add repositories on multiple platforms:
task "add-repo", "server1", "server2", sub {
repository add => myrepo => {
Ubuntu => {
url => "http://foo.bar/repo",
distro => "precise",
repository => "foo",
},
Debian => {
url => "http://foo.bar/repo",
distro => "squeeze",
repository => "foo",
},
CentOS => {
url => "http://foo.bar/repo",
},
};
};
To set another package provider as the default, use this function.
user "root";
group "db" => "db[01..10]";
package_provider_for SunOS => "blastwave";
task "prepare", group => "db", sub {
install package => "vim";
};
This example will install vim on every db server. If the server is a Solaris (SunOS) it will use the blastwave Repositories.
