🐜🐜🐜 Marabunta 🐜🐜🐜

Marabunta is a name given to the migration of the legionary ants or to the ants themselves. Restless, they eat and digest everything in their way.

Marabunta is used to provide an easy way to create Updates for Odoo fast and run easily. It also allows to differentiate between different environment to provide for instance demodata.

Usage

After installing marabunta, it will be available as a console command. To run properly it requires a migration file (which defines what has to updated/executed) and odoos connection parameters (view options in the options section.

At each run marabunta verifies the versions from the migration file and and processes new ones. It is very much recommended to configure it, so that marabunta is ran automatically if odoo is started. For instance adding it to your docker entrypoint.

Features

• backup: Marabunta allows for a backup command to be executed before the migration.
• addon upgrades: Marabunta is able to install or upgrade odoo addons.
• operations: Allows to execute commands before or after upgrading modules.
• modes: Modes allow the user to execute commands only on a certain environment. e.g. creation of demodata on a dev system.
• maintenance page: publish an html page during the migration.

Versioning systems

Currently Marabunta allows for two different Versioning systems: The classic Major.Minor.Bugfix and the Five digits long versions for OdooMajor.OdooMinor.Major.Minor.Bugfix. Although the first marabunta version must be setup for the initial setup of your instance.

YAML layout & Example

Here is an Example migration file:

migration:
  options:
    # This includes general options which are used everytime marabunta is called.
    # --workers=0 --stop-after-init are automatically added
    install_command: odoo #Command which starts odoo
    install_args: --log-level=debug # additional Arguments
    backup: # Defines how the backup should be done before the migration.
      command: echo "backup command on ${DB_NAME}"
      stop_on_failure: true
      ignore_if: test "${RUNNING_ENV}" != "prod"
  versions:
    - version: setup # Setup is always the initia. version<
      operations:
        pre:  # executed before 'addons'
          - echo 'pre-operation'
        post:  # executed after 'addons'
          - anthem songs::install
      addons:
        upgrade:  # executed as odoo --stop-after-init -i/-u ...
          - base
          - document
      modes:
        prod:
          operations:
            pre:
              - echo 'pre-operation executed only when the mode is prod'
            post:
              - anthem songs::load_production_data
        demo:
          operations:
            post:
              - anthem songs::load_demo_data
          addons:
            upgrade:
              - demo_addon

    - version: 0.0.2
      backup: false
      # nothing to do this can be used to keep marabunta and gittag in sync

    - version: 0.0.3
      operations:
        pre: # we also can execute os commands
          - echo 'foobar'
          - ls
          - bin/script_test.sh
        post:
          - echo 'post-op'

    - version: 0.0.4
      backup: false
      addons:
        upgrade:
          - popeye

Run the tests

To run marabunta tests, it is a good idea to do an editable install of it in a virtualenv, and then intall and run pytest as follows:

$ git clone https://github.com/camptocamp/marabunta.git
Cloning into 'marabunta'...
$ cd marabunta
$ virtualenv -p YOUR_PYTHON env
$ source env/bin/activate
$ pip install '.[test]'
$ py.test tests
