Doodba

ci

Doodba stands for Docker Odoo Base, and it is a highly opinionated image ready to put Odoo inside it, but without Odoo.

What?

Yes, the purpose of this is to serve as a base for you to build your own Odoo project, because most of them end up requiring a big amount of custom patches, merges, repositories, etc. With this image, you have a collection of good practices and tools to enable your team to have a standard Odoo project structure.

BTW, we use Debian. I hope you like that.

Why?

Because developing Odoo is hard. You need lots of customizations, dependencies, and if you want to move from one version to another, it's a pain.

Also because nobody wants Odoo as it comes from upstream, you most likely will need to add custom patches and addons, at least, so we need a way to put all together and make it work anywhere quickly.

How?

You can start working with this straight away with our template.

Image usage

Basically, every directory you have to worry about is found inside /opt/odoo. This is its structure:

custom/
    entrypoint.d/
    build.d/
    conf.d/
    ssh/
        config
        known_hosts
        id_rsa
        id_rsa.pub
    dependencies/
        apt_build.txt
        apt.txt
        gem.txt
        npm.txt
        pip.txt
    src/
        private/
        odoo/
        addons.yaml
        repos.yaml
common/
    entrypoint.sh
    build.sh
    entrypoint.d/
    build.d/
    conf.d/
auto
    addons/
    odoo.conf

Let's go one by one.

/opt/odoo/custom: The important one

Here you will put everything related to your project.

/opt/odoo/custom/entrypoint.d

Any executables found here will be run when you launch your container, before running the command you ask.

/opt/odoo/custom/build.d

Executables here will be aggregated with those in /opt/odoo/common/build.d.

The resulting set of executables will then be sorted alphabetically (ascending) and then subsequently run.

/opt/odoo/custom/conf.d

Files here will be environment-variable-expanded and concatenated in /opt/odoo/auto/odoo.conf in the entrypoint.

/opt/odoo/custom/ssh

It must follow the same structure as a standard ~/.ssh directory, including config and known_hosts files. In fact, it is completely equivalent to ~root/.ssh.

The config file can contain IdentityFile keys to represent the private key that should be used for that host. Unless specified otherwise, this defaults to identity[.pub], id_rsa[.pub] or id_dsa[.pub] files found in this same directory.

This is very useful to use deployment keys that grant git access to your private repositories.

Example - a private key file in the ssh folder named my_private_key for the host repo.example.com would have a config entry similar to the below:

Host repo.example.com
  IdentityFile ~/.ssh/my_private_key

Or you could just drop the key in id_rsa and id_rsa.pub files and it should work by default without the need of adding a config file.

Host key checking is enabled by default, which means that you also need to provide a known_hosts file for any repos that you wish to access via SSH.

In order to disable host key checks for a repo, your config would look something like this:

Host repo.example.com
  StrictHostKeyChecking no

For additional information regarding this directory, take a look at this Digital Ocean Article.

/opt/odoo/custom/src

Here you will put the actual source code for your project.

When putting code here, you can either:

  • Use repos.yaml, that will fill anything at build time.
  • Directly copy all there.

Recommendation: use repos.yaml for everything except for private, and ignore in your .gitignore and .dockerignore files every folder here except private, with rules like these:

odoo/custom/src/*
!odoo/custom/src/private
!odoo/custom/src/*.*
/opt/odoo/custom/src/odoo

REQUIRED. The source code for your odoo project.

You can choose your Odoo version, and even merge PRs from many of them using repos.yaml. Some versions you might consider:

  • Original Odoo, by Odoo S.A..

  • OCB (Odoo Community Backports), by OCA. The original + some features - some stability strictness.

  • OpenUpgrade, by OCA. The original, frozen at new version launch time + migration scripts.

/opt/odoo/custom/src/private

REQUIRED. Folder with private addons for the project.

/opt/odoo/custom/src/repos.yaml

A git-aggregator configuration file.

It should look similar to this:

# Odoo must be in the `odoo` folder for Doodba to work
odoo:
  defaults:
    # This will use git shallow clones.
    # $DEPTH_DEFAULT is 1 in test and prod, but 100 in devel.
    # $DEPTH_MERGE is always 100.
    # You can use any integer value, OTOH.
    depth: $DEPTH_MERGE
  remotes:
    origin: https://github.com/OCA/OCB.git
    odoo: https://github.com/odoo/odoo.git
    openupgrade: https://github.com/OCA/OpenUpgrade.git
  # $ODOO_VERSION is... the Odoo version! "11.0" or similar
  target: origin $ODOO_VERSION
  merges:
    - origin $ODOO_VERSION
    - odoo refs/pull/25594/head # Expose `Field` from search_filters.js

web:
  defaults:
    depth: $DEPTH_MERGE
  remotes:
    origin: https://github.com/OCA/web.git
    tecnativa: https://github.com/Tecnativa/partner-contact.git
  target: origin $ODOO_VERSION
  merges:
    - origin $ODOO_VERSION
    - origin refs/pull/1007/head # web_responsive search
    - tecnativa 11.0-some_addon-custom # Branch for this customer only
Automatic download of repos

Doodba is smart enough to download automatically git repositories even if they are missing in repos.yaml. It will happen if it is used in addons.yaml, except for the special private repo. This will help you keep your deployment definitions DRY.

You can configure this behavior with these environment variables (default values shown):

  • DEFAULT_REPO_PATTERN="https://github.com/OCA/{}.git"
  • DEFAULT_REPO_PATTERN_ODOO="https://github.com/OCA/OCB.git"

As you probably guessed, we use something like str.format(repo_basename) on top of those variables to compute the default remote origin. If, i.e., you want to use your own repositories as default remotes, just add these build arguments to your docker-compose.yaml file:

# [...]
services:
  odoo:
    build:
      args:
        DEFAULT_REPO_PATTERN: &origin "https://github.com/Tecnativa/{}.git"
        DEFAULT_REPO_PATTERN_ODOO: *origin
# [...]

So, for example, if your repos.yaml file is empty and your addons.yaml contains this:

server-tools:
  - module_auto_update

A /opt/odoo/auto/repos.yaml file with this will be generated and used to download git code:

/opt/odoo/custom/src/odoo:
  defaults:
    depth: $DEPTH_DEFAULT
  remotes:
    origin: https://github.com/OCA/OCB.git
  target: origin $ODOO_VERSION
  merges:
    - origin $ODOO_VERSION
/opt/odoo/custom/src/server-tools:
  defaults:
    depth: $DEPTH_DEFAULT
  remotes:
    origin: https://github.com/OCA/server-tools.git
  target: origin $ODOO_VERSION
  merges:
    - origin $ODOO_VERSION

All of this means that, you only need to define the git aggregator spec in repos.yaml if anything diverges from the standard:

  • You need special merges.
  • You need a special origin.
  • The folder name does not match the origin pattern.
  • The branch name does not match $ODOO_VERSION.
  • Etc.
/opt/odoo/custom/src/addons.yaml

One entry per repo and addon you want to activate in your project. Like this:

website:
  - website_cookie_notice
  - website_legal_page
web:
  - web_responsive

Advanced features:

  • You can bundle several YAML documents if you want to logically group your addons and some repos are repeated among groups, by separating each document with ---.

  • Addons under private and odoo/addons are linked automatically unless you specify them.

  • You can use ONLY to supply a dictionary of environment variables and a list of possible values to enable that document in the matching environments.

  • You can use ENV to supply a dictionary of environment variables to be used on downloading repositories. Following variables are supported:

    • DEFAULT_REPO_PATTERN
    • DEFAULT_REPO_PATTERN_ODOO
    • DEPTH_DEFAULT
    • ODOO_VERSION - can be used as repository branch
  • If an addon is found in several places at the same time, it will get linked according to this priority table:

    1. Addons in private.
    2. Addons in other repositories (in case one is matched in several, it will be random, BEWARE!). Better have no duplicated names if possible.
    3. Core Odoo addons from odoo/addons.
  • If an addon is specified but not available at runtime, it will fail silently.

  • You can use any wildcards supported by Python's glob module.

The following example shows these advanced features:

# Spanish Localization
l10n-spain:
  - l10n_es # Overrides built-in l10n_es under odoo/addons
server-tools:
  - "*date*" # All modules that contain "date" in their name
  - auditlog
web:
  - "*" # All web addons
---
# Different YAML document to separate SEO Tools
website:
  - website_blog_excertp_img
server-tools: # Here we repeat server-tools, but no problem because it's a
  # different document
  - html_image_url_extractor
  - html_text
---
# Enable demo ribbon only for devel and test environments
ONLY:
  PGDATABASE: # This environment variable must exist and be in the list
    - devel
    - test
web:
  - web_environment_ribbon
---
# Enable special authentication methods only in production environment
ONLY:
  PGDATABASE:
    - prod
server-tools:
  - auth_*
---
# Custom repositories
ENV:
  DEFAULT_REPO_PATTERN: https://github.com/Tecnativa/{}.git
  ODOO_VERSION: 15.0-new-feature
some-repo: # Cloned from https://github.com/Tecnativa/some-repo.git branch 15.0-new-feature
  - some_custom_module
/opt/odoo/custom/dependencies/*.txt

Files to indicate dependencies of your subimage, one for each of the supported package managers:

  • apt_build.txt: build-time dependencies, installed before any others and removed after all the others too. Usually these would include Debian packages such as build-essential or python-dev. From Doodba 11.0, this is most likely not needed, as build dependencies are shipped with the image, and local python develpment headers should be used instead of those downloaded from apt.
  • apt.txt: run-time dependencies installed by apt.
  • gem.txt: run-time dependencies installed by gem.
  • npm.txt: run-time dependencies installed by npm.
  • pip.txt: a normal pip requirements.txt file, for run-time dependencies too. It will get executed with --update flag, just in case you want to overwrite any of the pre-bundled dependencies.

/opt/odoo/common: The useful one

This folder is full of magic. I'll document it some day. For now, just look at the code.

Only some notes:

  • Will compile your code with [PYTHONOPTIMIZE=""][] by default.

  • Will remove all code not used from the image by default (not listed in /opt/odoo/custom/src/addons.yaml), to keep it thin.

/opt/odoo/auto: The automatic one

This directory will have things that are automatically generated at build time.

/opt/odoo/auto/addons

It will be full of symlinks to the addons you selected in addons.yaml.

/opt/odoo/auto/odoo.conf

It will have the result of merging all configurations under /opt/odoo/{common,custom}/conf.d/, in that order.

The Dockerfile

I will document all build arguments and environment variables some day, but for now keep this in mind:

  • This is just a base image, full of tools. You need to build your project subimage from this one, even if your project's Dockerfile only contains these 2 lines:

    FROM tecnativa/doodba
    MAINTAINER Me <me@example.com>
    
  • The above sentence becomes true because we have a lot of ONBUILD sentences here, so at least your project must have a ./custom folder along with its Dockerfile for it to work.

  • All should be magic if you adhere to our opinions here. Just put the code where it should go, and relax.

Bundled tools

There is a good collections of tools available in the image that help dealing with Odoo and its peculiarities:

addons

A handy CLI tool to automate addon management based on the current environment. It allows you to install, update, test and/or list private, extra and/or core addons available to current container, based on current addons.yaml configuration.

Call addons --help for usage instructions.

click-odoo and related scripts

The great click-odoo scripting framework and the collection of scripts found in click-odoo-contrib are included. Refer to their sites to know how to use them.

* Note: This replaces the deprecated python-odoo-shell binary.

nano

The CLI text editor we all know, just in case you need to inspect some bug in hot deployments.

log

Just a little shell script that you can use to add logs to your build or entrypoint scripts:

log INFO I'm informing

pot

Little shell shortcut for exporting a translation template from any addon(s). Usage:

pot my_addon,my_other_addon

psql

Environment variables are there so that if you need to connect with the database, you just need to execute:

docker-compose run -l traefik.enable=false --rm odoo psql

The same is true for any other Postgres client applications.

inotify

Enables hot code reloading when odoo is started with --dev and passed reload or all as an argument.

copier template enables this by default in the development environment.

Doodba supports this feature under versions 11.0 and later. Check CLI docs for details.

debugpy

VSCode debugger. If you use this editor with its python module, you will find it useful.

To debug at a certain point of the code, add this Python code somewhere:

import debugpy
debugpy.listen(6899)
print("Waiting for debugger attach")
debugpy.wait_for_client()
debugpy.breakpoint()
print('break on this line')

To start Odoo within a debugpy environment, which will obey the breakpoints established in your IDE (but will work slowly), just add -e DEBUGPY_ENABLE=1 to your odoo container.

If you use the official template, you can boot it in debugpy mode with:

export DOODBA_DEBUGPY_ENABLE=1
docker-compose -f devel.yaml up -d

Of course, you need to have properly configured your VSCode. To do so, make sure in your project there is a .vscode/launch.json file with these minimal contents:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Attach to debug in devel.yaml",
      "type": "python",
      "request": "attach",
      "pathMappings": [
        {
          "localRoot": "${workspaceRoot}/odoo",
          "remoteRoot": "/opt/odoo"
        }
      ],
      "port": 6899,
      "host": "localhost"
    }
  ]
}

Then, execute that configuration as usual.

pudb

This is another great debugger that includes remote debugging via telnet, which can be useful for some cases, or for people that prefer it over wdb.

To use it, inject this in any Python script:

import pudb.remote
pudb.remote.set_trace(term_size=(80, 24))

Then open a telnet connection to it (running in 0.0.0.0:6899 by default).

It is safe to use in production environments if you know what you are doing and do not expose the debugging port to attackers. Usage:

docker-compose exec odoo telnet localhost 6899

git-aggregator

We found this one to be the most useful tool for downlading code, merging it and placing it somewhere.

autoaggregate

This little script wraps git-aggregator to make it work fine and automatically with this image. Used in the template's setup-devel.yaml step.

Example repos.yaml file

This repos.yaml example merges several sources:

./odoo:
  defaults:
    # Shallow repositores are faster & thinner. You better use
    # $DEPTH_DEFAULT here when you need no merges.
    depth: $DEPTH_MERGE
  remotes:
    ocb: https://github.com/OCA/OCB.git
    odoo: https://github.com/odoo/odoo.git
  target: ocb $ODOO_VERSION
  merges:
    - ocb $ODOO_VERSION
    - odoo refs/pull/13635/head
  shell_command_after:
    # Useful to merge a diff when there's no git history correlation
    - curl -sSL https://github.com/odoo/odoo/pull/37187.diff | patch -fp1

odoo

We set an $OPENERP_SERVER environment variable pointing to the autogenerated configuration file so you don't have to worry about it. Just execute odoo and it will work fine.

Note that version 9.0 has an odoo binary to provide forward compatibility (but it has the odoo.py one too).

Subproject template

That's a big structure! Get it up and running quickly using the copier template we provide to help you generate your subproject.

Check its docs to know how to use it.

FAQ

Will there be not retrocompatible changes on the image?

This image is production-ready, but it is constantly evolving too, so some new features can break some old ones, or conflict with them, and some old features might get deprecated and removed at some point.

The best you can do is to subscribe to the compatibility breakage announcements issue.

This project is too opinionated, but can I question any of those opinions?

Of course. There's no guarantee that we will like it, but please do it. 😉

What's this hooks folder here?

It runs triggers when doing the automatic build in the Docker Hub. Check this.

How can I pin an image version?

Version-pinning is a good idea to keep your code from differing among image updates. It's the best way to ensure no updates got in between the last time you checked the image and the time you deploy it to production.

You can do it through its sha256 code.

Get any image's code through inspect, running from a computer where the correct image version is downloaded:

docker image inspect --format='{{.RepoDigests}}' tecnativa/doodba:10.0-onbuild

Alternatively, you can browse this image's builds, click on the one you know it works fine for you, and search for the digest word using your browser's search in page system (Ctrl+F usually).

You will find lines similar to:

[...]
10.0: digest: sha256:fba69478f9b0616561aa3aba4d18e4bcc2f728c9568057946c98d5d3817699e1 size: 4508
[...]
8.0: digest: sha256:27a3dd3a32ce6c4c259b4a184d8db0c6d94415696bec6c2668caafe755c6445e size: 4508
[...]
9.0: digest: sha256:33a540eca6441b950d633d3edc77d2cc46586717410f03d51c054ce348b2e977 size: 4508
[...]

Once you find them, you can use that pinned version in your builds, using a Dockerfile similar to this one:

# Hash-pinned version of tecnativa/doodba:10.0-onbuild
FROM tecnativa/doodba@sha256:fba69478f9b0616561aa3aba4d18e4bcc2f728c9568057946c98d5d3817699e1
