Kinto Emailer

kinto-emailer send emails when some events arise (e.g. new records have been created). It relies on Pyramid Mailer for the sending part.

Install

pip install kinto-emailer

Setup

In the Kinto settings:

kinto.includes = kinto_emailer

mail.default_sender = [email protected]

# mail.host = localhost
# mail.port = 25
# mail.username = None
# mail.password = None
# mail.tls = False
# mail.queue_path = None

If mail.queue_path is set, the emails are storage in a local Maildir queue.

See more details about Pyramid Mailer configuration.

Validate configuration

The following command will send a dummy email to the specified recipient or will fail if the configuration is not correct:

$ kinto-send-email config/kinto.ini [email protected]

Development

Use a fake emailer that write emails files to disk:

mail.debug_mailer = true

How does it work?

Some information — like monitored action or list of recipients — are defined in the collection or the bucket metadata. When an event occurs, the plugin sends emails if one of the expected condition is met.

Usage

The metadata on the collection (or the bucket) must look like this:

{
  "kinto-emailer": {
    "hooks": [{
      "template": "Something happened!",
      "recipients": ['Security reviewers <[email protected]>']
    }]
  }
}

In the above example, every action on the collection metadata or any record in that collection will trigger an email notification.

The metadata of the collection override the bucket metadata, they are not merged.

Optional:

• subject (e.g. "An action was performed")
• sender (e.g. "Kinto team <[email protected]>")

Recipients

The list of recipients can either contain:

• Email adresses (eg. [email protected] or "Joe Doe <[email protected]>")
• Group URI (eg. /buckets/staging/groups/reviewers)

With group URIs, the email recipients will be expanded with the group members principals look like email addresses (eg. ldap:[email protected]).

Selection

It is possible to define several hooks, and filter on some condition. For example:

{
  "kinto-emailer": {
    "hooks": [{
      "resource_name": "record",
      "action": "create",
      "template": "Record created!",
      "recipients": ['Security reviewers <[email protected]>']
    }, {
      "resource_name": "collection",
      "action": "updated",
      "template": "Collection updated!",
      "recipients": ["Security reviewers <[email protected]>"]
    }]
  }
}

The possible filters are:

• resource_name: record or collection (default: all)
• action: create, update, delete (default: all)
• collection_id (default: all)
• record_id (default: all)
• event: kinto.core.events.AfterResourceChanged (default), or kinto_remote_settings.signer.events.ReviewRequested, kinto_remote_settings.signer.events.ReviewApproved, kinto_remote_settings.signer.events.ReviewRejected

If a filter value starts with the special character ^, then the matching will consider the filter value to be a regular expression.

For example, in order to exclude a specific collection_id, set the filter value to: ^(?!normandy-recipes$).

Template

The template string can have placeholders:

• bucket_id
• id: record or collection id
• user_id
• resource_name
• uri
• action
• timestamp
• root_url
• client_address
• user_agent
• settings[name]

For example:

{user_id} has {action}d a {resource_name} in {bucket_id}.

Running the tests

To run the unit tests:

$ make tests

For the functional tests, run a Kinto instance in a separate terminal:

$ make run-kinto

And start the test suite:

$ make functional
