Cloud Platform

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

For the storage, we store all the attachments on a object storage such as S3 or a S3 compatible one, and we store the werkzeug sessions on Redis.

For the metrics, we produce logs as json (TODO) that is sent to ELK and send data to Prometheus/Grafana using statsd.

Setup

Python dependencies

Libraries that must be added in requirements.txt:

boto==2.42.0
redis==2.10.5

Server Environment

The server environments in server_environment_files must be at least:

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

prod: stored RW in the object storage
AWS_HOST: depends of the platform
AWS_ACCESS_KEY_ID: depends of the platform
AWS_SECRET_ACCESS_KEY: depends of the platform
AWS_BUCKETNAME: <client>-odoo-prod
integration: stored RO in the production object storage, fallback on database for the writes
AWS_HOST: depends of the platform
AWS_ACCESS_KEY_ID: depends of the platform
AWS_SECRET_ACCESS_KEY: depends of the platform
AWS_BUCKETNAME: <client>-odoo-prod (this is normal, we read only the data)
AWS_ATTACHMENT_READONLY: 1
test: attachments are stored in database

Besides, the

ir.config_parameter ir_attachment.location: s3:// (

Sessions in Redis

prod:
ODOO_SESSION_REDIS: 1
ODOO_SESSION_REDIS_HOST: depends of the platform
ODOO_SESSION_REDIS_PASSWORD: depends of the platform
ODOO_SESSION_REDIS_PREFIX: <client>-odoo-prod
integration:
ODOO_SESSION_REDIS: 1
ODOO_SESSION_REDIS_HOST: depends of the platform
ODOO_SESSION_REDIS_PASSWORD: depends of the platform
ODOO_SESSION_REDIS_PREFIX: <client>-odoo-integration
test:
ODOO_SESSION_REDIS: 1
ODOO_SESSION_REDIS_HOST: depends of the platform
ODOO_SESSION_REDIS_PASSWORD: depends of the platform
ODOO_SESSION_REDIS_PREFIX: <client>-odoo-test
ODOO_SESSION_REDIS_EXPIRATION: 86400 (1 day)

Automatic Configuration

Calling ctx.env['cloud.platform'].install_exoscale() in an anthem song will configure some parameters such as the ir_attachment.location and migrate the existing attachments to the object storage.

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.
