Short: "balancer override",
Long: `
Override a balancer's selection in a duration of time.
> Make sure you have "RoutingService" set in "config.api.services"
of server config.
Once a balancer's selection is overridden:
- The selectors of the balancer won't apply.
- The strategy of the balancer stops selecting qualified nodes
according to its settings, doing only the final pick.
Arguments:
-b, -balancer <tag>
Tag of the target balancer. Required.
-v, -validity <duration>
Time duration of the validity of override, e.g.: 60s, 60m,
24h, 1m30s. Default 1h.
-r, -remove
Remove the override
-s, -server <server:port>
The API server address. Default 127.0.0.1:8080
-t, -timeout <seconds>
Timeout seconds to call API. Default 3
Example:
{{.Exec}} {{.LongName}} --server=127.0.0.1:8080 -b balancer selector1 selector2
{{.Exec}} {{.LongName}} --server=127.0.0.1:8080 -b balancer -r
