## vespa config set

Set a configuration option.

```
vespa config set option-name value [flags]
```

### Examples

```
# Set the target to Vespa Cloud
$ vespa config set target cloud

# Set application, without a specific instance. The instance will be named "default"
$ vespa config set application my-tenant.my-application

# Set application with a specific instance
$ vespa config set application my-tenant.my-application.my-instance

# Set the instance explicitly. This will take precedence over an instance specified as part of the application option.
$ vespa config set instance other-instance

# Control whether config set/unset writes to local or global config by default
$ vespa config set default_config_scope local

# Set an option in local configuration, for the current application only. Overrides default_config_scope
$ vespa config set --local zone dev.aws-us-east-1c

# Set an option in global configuration. Overrides default_config_scope
$ vespa config set --global target cloud
```

### Options

```
-g, --global Write option to global configuration, overriding default_config_scope
  -h, --help help for set
  -l, --local Write option to local configuration, i.e. for the current application
```
