generic_cloudooo

The generic_cloudooo recipe helps you to deploy cloudooo services with their configuration files.

How to use generic_cloudooo?

Here is an example of a section to add in your software.cfg :

[cloudooo-configuration]
recipe = slapos.cookbook:generic_cloudooo
configuration-file = ${directory:etc}/cloudooo.cfg
wrapper = ${directory:services}/cloudooo
data-directory = ${directory:srv}/cloudooo
ip = 0.0.0.0
port = 1234
ooo-paster = ${directory:bin}/cloudooo_paster
mimetype_entry_addition =
  text/html application/pdf wkhtmltopdf
openoffice-port = 1235
ooo-binary-path = ${directory:libreoffice-bin}/program
environment =
  FONTCONFIG_FILE = $${fontconfig-conf:output}
  PATH = ${binary-link:target-directory}
ooo-uno-path = ${directory:libreoffice-bin}/basis-link/program

Where :

• configuration-file is the path where the put the configuration file;

• wrapper is the path where the put the final executable file;

• data-directory is the folder where cloudooo would put it’s temporary files;

• ip and port is where cloudooo will listen to;

• ooo-paster is the path of the program that will load cloudooo configuration and start the application;

• mimetype_entry_addition is additional entries to give to the default mimetype registry. (see section below.) The mimetype entry list is sorted in order to make the global mimetype at the bottom of the list. (i.e. * * ooo > text/* * ooo)

  mimetype_entry_addition =
    <input_format> <output_format> <handler>

• openoffice-port is the port where the internal OpenOffice.org service will listen to;

• ooo-binary-path is the path of the openoffice service executable file;

• environment are environment vars to use with the openoffice binary;

• ooo-uno-path is the path where UNO library is installed.

Default mimetype registry

librecipe

Thanks to using slapos.cookbook:librecipe it is easier to create zc.buildout recipes in SlapOS environment.

How to use?

In setup.py of recipe add only one install requires to slap.lib.recipe.

In code itself subclass from slap.lib.recipe.BaseSlapRecipe.BaseSlapRecipe.

Use _install hook:

from slap.lib.recipe.BaseSlapRecipe import BaseSlapRecipe

class Recipe(BaseSlapRecipe):
  ...
  def _install(self):
    # refer below for list of available objects
    specific code
    of recipe

Available variables self.:

• name and options passed by zc.buildout during init

• work_directory – buildout’s directory

• bin_directory – places for generated binaries

• running_wrapper_location – filename of wrapper to create

• data_root_directory – directory container for data – inside this directory it is advised to create named directories for provided servers which needs data

• backup_directory – directory container for backups – inside this directory it is advised o created named directories for backups, with same structure as in data_root_directory

• var_directory – container for various, unix following things:

  • log_directory – container for logs

  • run_directory – container for pidfiles and sockets

• etc_directory – place to put named files and directories of configuration for provided servers

• computer_id – id of computer

• computer_partition_id – if of computer partition

• server_url - url of Vifib server

• software_release_url – url of software release being instantiated

• slap – initialised connection to Vifib server

• computer_partition – initialised connection to computer partition

• request – shortcut to computer partition request method

By default all directories are created before calling _install hook.

_install method shall return list of paths which are safe to be removed by buildout during part uninstallation.

Important assumptions

Because in SlapOS environment zc.buildout does not know when data are changed, recipes shall be always uninstalled/installed. This is done during constructing recipe instance which subclasses from BaseSlapRecipe.

mkdirectory

mkdirectory loops on its options and create the directory joined

Note

Use a slash / as directory separator. Don’t use system dependent separator. The slash will be parsed and replace by the operating system right separator.

Only use relative directory to the buildout root directory.

The created directory won’t be added to path list.

These recipes provide the ability to save some buildout parameters and their value in a custom file, inside the instance folder.

In both recipes, you HAVE TO give a filename, which will be stored at the root of the instance folder

WriteRecipe :

• Is used to create a section (named according to the buildout section_name).

• You can give then as much parameters you wish, with their default values.

• Whenever you run buildout, if the parameter has yet been saved in the config file, it will do nothing.

• If the parameter’s value has changed in the config file, it won’t be overwritten

• /!If you decide to change the default value of one parameter, ALL other parameters will be reseted in the config file, even if you changed it manually. Explanation : The default values aren’t expected to change, except while development purposes.

ReadRecipe :

• It fills its own section with all the options in all the sections of the config file.
