Alibaba Cloud Service Mesh:GetSwimLaneGroupList

Last Updated:Feb 11, 2026

Lists all traffic lane groups in a Service Mesh (ASM) instance.

Operation description

调用DescribeASMSidecarExpectedVersion可以查询ASM数据面Sidecar的期望版本,例如升级ASM之前,注入Sidecar的版本为v1.11,然后升级ASM到v1.12,Pod没有重启,Sidecar的实际版本仍然为v1.11,但是调用DescribeASMSidecarExpectedVersion这个接口将查询到Sidecar版本是v1.12。

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

RequestId

string

The request ID.

yyyy

SwimLaneGroupList

array<object>

A list of traffic lane groups.

object

The details of a traffic lane group.

GroupName

string

The name of the traffic lane group.

test

ServiceList

string

A serialized JSON string that lists the services associated with the traffic lane group.

["sh01/c089443ea9e50403fa4f0a6237d11e0a9/default/mocka","sh01/c089443ea9e50403fa4f0a6237d11e0a9/default/mockb","sh01/c089443ea9e50403fa4f0a6237d11e0a9/default/mockc"]

IngressType

string

The type of ingress gateway. Only ASM gateways support traffic shifting. The value must be ASM.

ASM

IngressGatewayName

string

The name of the ASM gateway.

ingressgateway

IsPermissive

boolean

Specifies whether the traffic lane group is in loose mode.

false

FallbackTarget

string

The name of the baseline traffic lane for the traffic lane group. This parameter applies only if the group is in loose mode (IsPermissive is true).

s1

TraceHeader

string

The request header for trace pass-through in a traffic lane group that is in loose mode.

my-request-id

RouteHeader

string

The request header for traffic shifting when the traffic lane group is in loose mode.

x-asm-prefer-tag

SwimLaneLabels

string

A serialized JSON string. Each key represents a label key that is common to all services in the traffic lane group. The corresponding value is an array of all possible values for that label key.

{"ASM_TRAFFIC_TAG":["v2","v3","v1"],"version":["v3","v1","v2"]}

IngressRoutingStrategy

string

The policy for shifting traffic to different traffic lanes within the traffic lane group. Valid values:

  • weighted: A policy that distributes traffic based on weights. A single rule matches requests, and the policy then distributes matched requests to different traffic lanes based on specified proportions.

  • rule-based: A policy that routes traffic based on specific rules. Each traffic lane has a unique matching rule, and a request is routed to a lane only if it matches that lane's rule.

Valid values:

  • weighted :

    weighted

  • rule-based :

    rule-based

weighted

WeightedIngressRule

string

The traffic shifting rule for the entire traffic lane group. This parameter applies only when the traffic shifting policy is weighted.

{"Domains":["*"],"MatchRequests":[{"URI":{"MatchingMode":"exact","MatchingContent":"/mock"},"Headers":[{"Name":"test","MatchingMode":"exact","MatchingContent":"yes"}]}]}

ServiceLevelFallbackTarget

string

Specifies a fallback version for each service. This setting overrides the group-level fallback policy.
