Production Deployments

This document shows some of the Production options that may be useful. We will continue to add to this document and welcome users of Gloo Edge to send PRs to this as well.

Dropping capabilities

One of the more important (and unique) things about Gloo Edge is the ability to significantly lock down the edge proxy. Other proxies require privileges to write to disk or access the Kubernetes API, while Gloo Edge splits those responsibilities between control plane and data plane. The data plane can be locked down with zero privileges while separating out the need to secure the control plane differently.

For example, Gloo Edge’s data plane (the gateway-proxy pod) has ReadOnly file system. Additionally it doesn’t require any additional tokens mounted in or OS-level privileges. By default some of these options are enabled to simplify developer experience, but if your use case doesn’t need them, you should lock them down.

Enable replacing invalid routes

Enable health checks

Liveness/readiness probes on Envoy are disabled by default. This is because Envoy’s behavior can be surprising: When there are no routes configured, Envoy reports itself as un-ready. As it becomes configured with a nonzero number of routes, it will start to report itself as ready.
