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

apiVersion: kuma.io/v1alpha1
kind: Timeout
mesh: default
metadata:
  name: timeouts-backend
spec:
  sources:
    - match:
        kuma.io/service: '*'
  destinations:
    - match:
        kuma.io/service: 'backend_default_svc_80'
  conf:
    # connectTimeout defines time to establish connection, 'connect_timeout' on Cluster, default 10s
    connectTimeout: 10s
    tcp:
      # 'idle_timeout' on TCPProxy, disabled by default
      idleTimeout: 1h
    http:
      # 'timeout' on Route, disabled by default
      requestTimeout: 5s
      # 'idle_timeout' on Cluster, disabled by default
      idleTimeout: 1h
    grpc:
      # 'stream_idle_timeout' on HttpConnectionManager, disabled by default
      streamIdleTimeout: 5m
      # 'max_stream_duration' on Cluster, disabled by default
      maxStreamDuration: 30m

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

type: Timeout
mesh: default
name: timeouts-backend
sources:
  - match:
      kuma.io/service: '*'
destinations:
  - match:
      kuma.io/service: 'backend'
conf:
  # connectTimeout defines time to establish connection, 'connect_timeout' on Cluster, default 10s
  connectTimeout: 10s
  tcp:
    # 'idle_timeout' on TCPProxy, disabled by default
    idleTimeout: 1h
  http:
    # 'timeout' on Route, disabled by default
    requestTimeout: 5s
    # 'idle_timeout' on Cluster, disabled by default
    idleTimeout: 1h
  grpc:
    # 'stream_idle_timeout' on HttpConnectionManager, disabled by default
    streamIdleTimeout: 5m
    # 'max_stream_duration' on Cluster, disabled by default
    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.
