# Static selector
|
|
|
|
The Static selector returns the named service as a node for every request. This is useful where you want to
|
|
offload discovery and balancing to DNS (particularly useful with KubeDNS).
|
|
|
|
This DOES however require a static port assignment (because we no longer have the ability to look up metadata). This defaults to port 8080, but can be overriddden at runtime using env-vars.
|
|
|
|
An optional domain-name can be appended too.
|
|
|
|
|
|
## Environment variables
|
|
|
|
* "STATIC_SELECTOR_DOMAIN_NAME": An optional domain-name to append to the speicified service name.
|
|
* "STATIC_SELECTOR_PORT_NUMBER": Override the default port (8080) for "discovered" services.
|
|
|
|
|
|
## Usage
|
|
|
|
```go
|
|
selector := static.NewSelector()
|
|
|
|
service := micro.NewService(
|
|
client.NewClient(client.Selector(selector))
|
|
)
|
|
```
