Runtime configuration |
|
===================== |
|
|
|
Envoy supports “runtime” configuration (also known as "feature flags" and "decider"). Configuration |
|
settings can be altered that will affect operation without needing to restart Envoy or change the |
|
primary configuration. The currently supported implementation uses a tree of file system files. |
|
Envoy watches for a symbolic link swap in a configured directory and reloads the tree when that |
|
happens. This type of system is very commonly deployed in large distributed systems. Other |
|
implementations would not be difficult to implement. Supported runtime configuration settings are |
|
documented in the relevant sections of the operations guide. Envoy will operate correctly with |
|
default runtime values and a “null” provider so it is not required that such a system exists to run |
|
Envoy. |
|
|
|
Runtime :ref:`configuration <config_runtime>`.
