Inventory cache
If you want to cache the inventory and to use this cache for subsequent rex calls, you can use the REX_CACHE_TYPE environment variable.
REX_CACHE_TYPE=YAML rex $task
This will create a folder ".cache" and creates a separate cache file for each host. If you want to use a different folder you can set it in the REX_CACHE_PATH environment variable.
You can also set the cache type inside your Rexfile
# Rexfile
user "root";
password "...";
cache "YAML";
It is also possible to create custom cache classes. For example if you want to save the inventory cache inside a database. Just take a look at Rex::Interface::Cache::YAML to see how it is implemented.
Reporting of changes
If you want to get a report of the changes Rex had done on your systems, you can use the new reporting feature.
Currently not every Rex function gets monitored by this feature, but all important ones are. This feature will be extended with version 2 of rex.
To activate the reporting you can use the REX_REPORT_TYPE environment variable or use the reporting feature inside your Rexfile.
REX_REPORT_TYPE=YAML rex the-task
Or, within the Rexfile
# Rexfile
use Rex -base;
report -on => "YAML";
The YAML report will be created inside a directory called report. If you want to use a different directory you can set it with a special variable.
use Rex -base;
report -on => "YAML";
set report_path => "/path/to/";
It is also possible to create custom reporting classes. Just take a look at Rex::Report::RexIO.
New CLI commands to better integrate Rex into your shell scripts
With these commands it is easy to use Rex from within a shell script.
You can test these scripts by checking out the krimdomu/rex-shell-extension GitHub repository.
Login to fe01.my.lan and execute uptime
#!/bin/bash
export REX_REMOTE_HOST="fe01.my.lan"
GROUPS=$(rex-run "id -Gn www-data")
for group in $GROUPS; do
echo $group
done
Login to fe01.my.lan, testing if /etc/sudoers is there, and if not, install package and upload a template sudoers file
#!/bin/bash
export REX_REMOTE_HOST="fe01.my.lan"
if ! rex-test -f /etc/sudoers; then
rex-install sudo
rex-template files/sudoers.tpl | rex-upload "/etc/sudoers"
