Asset registration

Assets are the best way to make use of this plugin. If you're not using an asset, please consider doing so! If you're using sensuctl 5.13 or later, you can use the following command to add the asset:

sensuctl asset add nixwiz/sensu-go-flowdock-handler

If you're using an earlier version of sensuctl, you can download the asset definition from this project's Bonsai asset index page or one of the existing releases or create an executable script from this source.

To build from source, from the local path of the sensu-go-flowdock-handler repository:

go build -o /usr/local/bin/sensu-go-flowdock-handler main.go

Handler definition

api_version: core/v2
type: Handler
metadata:
  namespace: default
  name: flowdock
spec:
  type: pipe
  command: sensu-go-flowdock-handler -b http://sensu-backend.example.com:3000
  filters:
  - is_incident
  - not_silenced
  runtime_assets:
  - nixwiz/sensu-go-flowdock-handler
  secrets:
  - name: SENSU_FLOWDOCK_TOKEN
    secret: flowdock-token#key
  timeout: 10

Security Note: The Flowdock Token should always be treated as a security
sensitive configuration option and in this example, it is loaded into the
handler configuration as an environment variable using a secret. Command
arguments are commonly readable from the process table by other unpriviledged
users on a system (ex: ps and top commands), so it's a better practice to read
in sensitive information via environment variables or configuration files on
disk. The --flowdockToken flag is provided as an override for testing purposes.

Additional notes

Flowdock Configuration

This handler makes use of Flowdock's "new" Integration API mechanism. This means creating a developer application
and then a source. This source will have the API Token needed by this handler.

Note: Actions for these messages are not implemented.
