If passwordless ssh login to localhost and passwordless sudo is enabled on your machine, you should be able to deploy blueprints with no special configuration, just by specifying location: localhost in YAML.
If you use a passpharse or prefer a different key, these can be configured as follows:
{% highlight bash %} brooklyn.location.localhost.privateKeyFile=~/.ssh/brooklyn_key brooklyn.location.localhost.privateKeyPassphrase=s3cr3tPASSPHRASE {% endhighlight %}
Alternatively, you can create a specific localhost location through the location wizard tool available within the web console. This location will be saved as a [catalog entry]({{ site.path.guide }}/ops/catalog/index.html#locations-in-catalog) for easy reusability.
If you encounter issues or for more information, see SSH Keys Localhost Setup.
If you are normally prompted for a password when executing sudo commands, passwordless sudo must also be enabled. To enable passwordless sudo for your account, a line must be added to the system /etc/sudoers file. To edit the file, use the visudo command: {% highlight bash %} sudo visudo {% endhighlight %} Add this line at the bottom of the file, replacing username with your own user: {% highlight bash %} username ALL=(ALL) NOPASSWD: ALL {% endhighlight %} If executing the following command does not ask for your password, then sudo should be setup correctly: {% highlight bash %} sudo ls {% endhighlight %}
