How to: Configuration
- `SENTRY_DSN` - Sentry DSN that will be used by the agent.

- `SENTRY_ENVIRONMENT` - Sentry environment that will be used for reported events.

- `SENTRY_K8S_WATCH_NAMESPACES` - a comma-separated list of namespaces that will be watched. Only the `default` namespace is watched by default. If you want to watch all namespaces, set the varible to value `__all__`.

- `SENTRY_K8S_WATCH_HISTORICAL` - if set to `1`, all existing (old) events will also be reported. Default is `0` (old events will not be reported).

- `SENTRY_K8S_CLUSTER_CONFIG_TYPE` - the type of the cluster initialization method. Allowed options: `auto`, `in-cluster`, `out-cluster`. Default is `auto`.

- `SENTRY_K8S_KUBECONFIG_PATH` - filesystem path to the `kubeconfig` configuration that will be used to connect to the cluster. Not used if `SENTRY_K8S_CLUSTER_CONFIG_TYPE` is set to `in-cluster`.

- `SENTRY_K8S_LOG_LEVEL` - logging level. Can be `trace`, `debug`, `info`, `warn`, `error`, `disabled`. Default is `info`.

- `SENTRY_K8S_MONITOR_CRONJOBS` - if set to `1`, enables Sentry Crons integration for `CronJob` objects. Disabled by default.

- `SENTRY_K8S_CUSTOM_DSNS` - if set to `1`, enables custom DSN to be specified in the `annotations` with key `k8s.sentry.io/dsn` which would take precedence over `SENTRY_DSN. Disabled by default.
