Configuration: Static¶
To start Envoy with static configuration, you will need to specify listeners and clusters as static_resources.
You can also add an admin section if you wish to monitor Envoy or retrieve stats.
The following sections walk through the static configuration provided in the
demo configuration file
used as the default in the Envoy Docker container.
static_resources
¶
The static_resources contain everything that is configured statically when Envoy starts, as opposed to dynamically at runtime.
1static_resources:
2
3 listeners:
listeners
¶
The example configures a listener
on port 10000
.
All paths are matched and routed to the service_envoyproxy_io
cluster.
