Odoo Cloud Addons
Camptocamp odoo addons used on our Cloud Platform.
Introduction
On the platform we want to achieve having:
- No data stored on the local filesystem so we can move an instance between hosts and even have several running front-ends
- Metrics read from the logs or sent to Prometheus to monitor the instances
- Logs sent to ElasticSearch-Kibana structured as JSON for better searching
For the storage, we store all the attachments on an object storage such as S3 or Swift, and we store the werkzeug sessions on Redis.
Setup
Python dependencies
Libraries that must be added in requirements.txt
:
redis==2.10.5
python-json-logger==0.1.5
statsd==3.2.1
# For S3 object storage (Exoscale, AWS)
boto==2.42.0
# For Swift object storage (Openstack, OVH)
python-swiftclient==3.4.0
python-keystoneclient==3.13.0
Odoo Startup
The --load
option of Odoo must contains the following addons:
session_redis
logging_json
Example:
--load=web,web_kanban,session_redis,logging_json
Server Environment
The addon cloud_platform
is an addon that we use for 2 things:
- validate that we setup the required environment variables depending on the running environment
- install and configure the cloud addons
For this purpose, we use the server_environment
with the following envs:
prod
integration
test
dev
The exact naming is important, because the cloud_platform
addon rely on these keys to know and check the running environment.
Attachments in the Object Storage S3
- prod: stored RW in the object storage
AWS_HOST
: depends of the platformAWS_REGION
: region's endpointAWS_ACCESS_KEY_ID
: depends of the platformAWS_SECRET_ACCESS_KEY
: depends of the platformAWS_BUCKETNAME
:<project>-odoo-prod
- integration:
AWS_ACCESS_KEY_ID
: depends of the platformAWS_SECRET_ACCESS_KEY
: depends of the platformAWS_BUCKETNAME
:<project>-odoo-integration
- test: attachments are stored in database
Besides, the attachment location should be set to s3
(this is
automatically done by the install
methods of the cloud_platform
module).

JSON Logging
At least on production and integration, activate:
ODOO_LOGGING_JSON
: 1- Add
logging_json
in theserver_wide_modules
option in the configuration file
Metrics (Statsd/Prometheus for Grafana)
Should be active at least on the production server
ODOO_STATSD
: 1STATSD_CUSTOMER
:<project>
STATSD_ENVIRONMENT
: set if you want to send metrics for a special environment which does not match with theserver_environment
STATSD_HOST
: depends of the platformSTATSD_PORT
: depends of the platform
Automatic Configuration
An automatic configuration can be executed from an anthem
song to configure
some parameters such as the ir_attachment.location
and migrate the existing
attachments to the object storage.
From anthem
, it can be called like this:
ctx.env['cloud.platform'].install(cloud_platform_kind)
Replacing cloud_platform_kind
with 'exoscale' or 'ovh'
Or using one of the direct shortcuts:
ctx.env['cloud.platform'].install_exoscale()
ctx.env['cloud.platform'].install_ovh()
Startup checks
At loading of the database, the addon will check if the environment variables for Redis and the object storage are set as expected for the loaded environment. It will refuse to start if anything is badly configured.
The checks can be bypassed with the environment variable
ODOO_CLOUD_PLATFORM_UNSAFE
set to 1
