Timeout

This policy enables Kuma to set timeouts on the outbound connections depending on the protocol.

Usage

Specify the proxy to configure with the sources selector, and the outbound connections from the proxy with the destinations selector.

The policy lets you configure timeouts for HTTP, GRPC, and TCP protocols.

Example

  1. apiVersion: kuma.io/v1alpha1
  2. kind: Timeout
  3. mesh: default
  4. metadata:
  5.   name: timeouts-backend
  6. spec:
  7.   sources:
  8.     - match:
  9.         kuma.io/service: '*'
  10.   destinations:
  11.     - match:
  12.         kuma.io/service: 'backend_default_svc_80'
  13.   conf:
  14.     # connectTimeout defines time to establish connection, 'connect_timeout' on Cluster, default 10s
  15.     connectTimeout: 10s
  16.     tcp:
  17.       # 'idle_timeout' on TCPProxy, disabled by default
  18.       idleTimeout: 1h
  19.     http:
  20.       # 'timeout' on Route, disabled by default
  21.       requestTimeout: 5s
  22.       # 'idle_timeout' on Cluster, disabled by default
  23.       idleTimeout: 1h
  24.     grpc:
  25.       # 'stream_idle_timeout' on HttpConnectionManager, disabled by default
  26.       streamIdleTimeout: 5m
  27.       # 'max_stream_duration' on Cluster, disabled by default
  28.       maxStreamDuration: 30m

We will apply the configuration with kubectl apply -f [..].

  1. type: Timeout
  2. mesh: default

  4. sources:
  5.   - match:
  6.       kuma.io/service: '*'
  7. destinations:
  8.   - match:
  9.       kuma.io/service: 'backend'
  10. conf:
  11.   # connectTimeout defines time to establish connection, 'connect_timeout' on Cluster, default 10s
  12.   connectTimeout: 10s
  13.   tcp:
  14.     # 'idle_timeout' on TCPProxy, disabled by default
  15.     idleTimeout: 1h
  16.   http:
  17.     # 'timeout' on Route, disabled by default
  18.     requestTimeout: 5s
  19.     # 'idle_timeout' on Cluster, disabled by default
  20.     idleTimeout: 1h
  21.   grpc:
  22.     # 'stream_idle_timeout' on HttpConnectionManager, disabled by default
  23.     streamIdleTimeout: 5m
  24.     # 'max_stream_duration' on Cluster, disabled by default
  25.     maxStreamDuration: 30m

We will apply the configuration with kumactl apply -f [..] or via the HTTP API.

Matching

Timeout is an Outbound Connection Policy. The only supported value for destinations.match is kuma.io/service.
