Event router
------------
A pod forwarding kubernetes events to EFK aggregated logging stack.
- **eventrouter** is deployed to default project, has a service account and its own role to read events
- **eventrouter** watches kubernetes events, marshalls them to JSON and outputs to its sink, currently only various formatting to STDOUT
- **fluentd** ingests as logs from **eventrouter** container (as it would any other container), and writes them to the appropriate index for the **eventrouter**'s namespace (in the 'default' namespace, the *.operations* index is used)
- `openshift_logging_install_eventrouter`: When 'True', eventrouter will be installed. When 'False', eventrouter will be uninstalled.
Configuration variables:
- `openshift_logging_eventrouter_image_prefix`: The prefix for the eventrouter logging image. Defaults to `openshift_logging_image_prefix`.
- `openshift_logging_eventrouter_image_version`: The image version for the logging eventrouter. Defaults to 'latest'.
- `openshift_logging_eventrouter_sink`: Select a sink for eventrouter, supported 'stdout' and 'glog'. Defaults to 'stdout'.
- `openshift_logging_eventrouter_nodeselector`: A map of labels (e.g. {"node":"infra","region":"west"} to select the nodes where the pod will land.
- `openshift_logging_eventrouter_cpu_request`: The minimum amount of CPU to allocate to eventrouter. Defaults to '100m'.
- `openshift_logging_eventrouter_memory_limit`: The memory limit for eventrouter pods. Defaults to '128Mi'.
