Mgmt

A configuration mgmt tool

History

The name of this tool has been taken from mgmt

The host configuration syntax is mostly copied from ansible (or maybe because it's yaml I think I copied it from ansible)

Usage

mgmt -h gives you a complete list of options.

Note some actions might requires root privileges so either run it via sudo or execute as root.

By default the only things you would need for is to specify a --host-config <filename> to tell mgmt what action perform on the server.

Depending the kind of installation that you went for (global or local) you might want to adjust the --host-config-directory variable.

Requirements

In order to use mgmt you need on your system Python >=3.4.

So far the only external requirements is pyyaml and jinja2.

Either run pip install -r requirements.txt or use the package provided by your distribution (on Debian / Ubunty system apt-get install python-yaml python-jinja2 should be enough)

For convenience on Debian/Ubuntu system a bootstrap.sh script has been added.

File configuration

The configuration for a host is following the yaml syntax. What is really necessary is to define a group of actions (list). Every action requires at the least a container called name that list at least one action.

N.B. Actions have to be available in the operation_registry at parse time.

Action params:

action params are directly coupled to the function we want to call. Unnecessary action might be ignored.

Example:

Given the function

func(paramA, paramB, paramC='something')

The corrisponding necessary action definition should look like:

---
host: localhost
actions:
  - meta:
      description:
      dependencies:
    name: test
    action_name:
      test1:
        paramA: 'paramA'
        paramB: 'paramB'
...

Full example:

---
host: localhost
actions:
  - name: install_index_php
    meta:
     dependencies: ['install_apache2']
     description: 'Copying index.php to apache document root'
    action_name:
      copy:
        source: 'data/index.php'
        destination: '/var/www/html'
  - name: 'install_apache2'
    meta:
      description: 'Install apache'
    action_name:
      install_package:
        packagename: 'apache2'
        cmd_after: 'rm -f /var/www/html/index.html'
  - name: install_php5
    meta:
      description: 'Install php'
      dependecies: ['install_apache2']
    action_name:
      install_package:
        packagename: 'php5 libapache2-mod-php5'
...

Test
