Environment Variables

Most arguments for this handler are available to be set via environment variables. However, any
arguments specified directly on the command line override the corresponding environment variable.

Security Note: Care should be taken to not expose the auth token for this handler by specifying it
on the command line or by directly setting the environment variable in the handler definition. It is
suggested to make use of secrets management to surface it as an environment variable. The
handler definition above references it as a secret. Below is an example secrets definition that make
use of the built-in env secrets provider.

---
type: Secret
api_version: secrets/v1
metadata:
  name: opsgenie_authtoken
spec:
  provider: env
  id: OPSGENIE_AUTHTOKEN

Argument Annotations

All arguments for this handler are tunable on a per entity or check basis based on annotations. The
annotations keyspace for this handler is sensu.io/plugins/sensu-opsgenie-handler/config.

Examples

To change the team argument for a particular check, for that checks's metadata add the following:

type: CheckConfig
api_version: core/v2
metadata:
  annotations:
    sensu.io/plugins/sensu-opsgenie-handler/config/team: WebOps
[...]

Proxy Support

This handler supports the use of the environment variables HTTP_PROXY,
HTTPS_PROXY, and NO_PROXY (or the lowercase versions thereof). HTTPS_PROXY takes
precedence over HTTP_PROXY for https requests. The environment values may be
either a complete URL or a "host[:port]", in which case the "http" scheme is assumed.
