local port to listen for those connections. When transparent proxy is enabled,
this annotation is optional.
- Services
The name of the service is the name of the service registered with Consul. You can optionally specify datacenters with this annotation.
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name]:[port]:[optional datacenter]"
```
- Consul Enterprise Namespaces
If running Consul Enterprise 1.7+, your upstream services may be running in different
namespaces. The upstream namespace can be specified after the service name
as `[service-name].[namespace]`. See [Consul Enterprise Namespaces](#consul-enterprise-namespaces)
below for more details on configuring the injector.
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].[service-namespace]:[port]:[optional datacenter]"
```
-> **NOTE:** If the namespace is not specified it will default to the namespace
of the source service.
~> **WARNING:** Setting a namespace when not using Consul Enterprise or using a version < 1.7
is not supported. It will be treated as part of the service name.
- [Prepared Query](/docs/connect/proxies#dynamic-upstreams-require-native-integration)
```yaml
annotations:
'consul.hashicorp.com/connect-service-upstreams': 'prepared_query:[query name]:[port]'
```
- Multiple Upstreams
If you would like to specify multiple services or upstreams, delimit them with commas
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name]:[port]:[optional datacenter],[service-name]:[port]:[optional datacenter]"
```
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name]:[port]:[optional datacenter],prepared_query:[query name]:[port]"
```
- There are a few formats this annotation can take:
- Unlabeled:
The unlabeled annotation format supports specifying service name, Consul Enterprise Namespaces and Partitions,
and datacenter. To use [cluster peering](/docs/connect/cluster-peering/k8s) with upstreams, use the labeled format below.
- Service Name
To specify the upstream service, you can provide the name of the service, and optionally, it's datacenter.
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name]:[port]:[optional datacenter]"
```
- Consul Enterprise Namespace
When using Consul Enterprise Namespaces [1.7+], your upstream services may be running in different namespaces.
The upstream namespace can be specified after the service name as `[service-name].[namespace]`. See [Consul
Enterprise Namespaces](#consul-enterprise-namespaces) below for more details on configuring the injector.
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].[service-namespace]:[port]:[optional datacenter]"
```
-> **NOTE:** If the namespace is not specified it will default to the namespace
of the source service.
~> **WARNING:** Setting a namespace when not using Consul Enterprise or using a version < 1.7
is not supported. It will be treated as part of the service name.
- Consul Enterprise Admin Partition
When using Consul Enterprise Admin Partitions [1.11+], your upstream services may be running in a different
partition. You must specify the namespace when specifying a partition, and the datacenter must be your local
datacenter if specified. Communicating across partitions using this method is only supported within a
datacenter. For cross partition communication across datacenters, see [cluster
peering](/docs/connect/cluster-peering/k8s).
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].[service-namespace].[service-partition]:[port]:[optional datacenter]"
```
- [Prepared Query](/docs/connect/proxies#dynamic-upstreams-require-native-integration):
Prepared query upstreams can use the format below.
```yaml
annotations:
'consul.hashicorp.com/connect-service-upstreams': 'prepared_query:[query name]:[port]'
```
- Labeled (requires consul-k8s v0.45.0+):
The labeled format is required when using the cluster peering feature and specifying an upstream in another
peer. It also supports specifying Consul Enterprise Namespace, Partition, or Datacenter. Only one of peer,
datacenter, or partition can be specified.
- Service Name
To specify the upstream service, you can provide the name of the service, followed by `.svc`.
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].svc:[port]"
```
- Peer or Datacenter
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].svc.[service-peer].peer:[port]"
```
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].svc.[service-dc].dc:[port]"
```
- Consul Enterprise
You can specify a Consul Enterprise Namespace
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].svc.[service-namespace].ns:[port]"
```
When specifying a peer, datacenter or Consul Enterprise Admin Partition when namespaces are enabled, you must
provide the namespace and one of (peer, datacenter, partition).
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].svc.[service-namespace].ns.[service-peer].peer:[port]"
```
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].svc.[service-namespace].ns.[service-partition].ap:[port]"
```
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name].svc.[service-namespace].ns.[service-dc].dc:[port]"
```
- Multiple Upstreams
If you would like to specify multiple services or upstreams, delimit them with commas. They can be of any of the Unlabeled, Labeled, or Prepared Query formats above when using the supported versions for the formats.
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name]:[port]:[optional datacenter],[service-name]:[port]:[optional datacenter]"
```
```yaml
annotations:
"consul.hashicorp.com/connect-service-upstreams":"[service-name]:[port]:[optional datacenter],prepared_query:[query name]:[port],[service-name].svc:[port]"
```
