# Scripted Deployment

Before you begin, make sure you have installed all the dependencies necessary for your operating system as described in the [README](../README.md).

You can deploy Algo non-interactively by running the Ansible playbooks directly with `ansible-playbook`.

`ansible-playbook` accepts "tags" via the `-t` or `TAGS` options. You can pass tags as a list of comma separated values. Ansible will only run plays (install roles) with the specified tags.

`ansible-playbook` accepts variables via the `-e` or `--extra-vars` option. You can pass variables as space separated key=value pairs. Algo requires certain variables that are listed below.

Here is a full example for DigitalOcean:

```shell
ansible-playbook deploy.yml -t digitalocean,vpn,cloud -e 'do_access_token=my_secret_token do_server_name=algo.local do_region=ams2'
```

### Ansible roles

Required tags:

- cloud

Cloud roles:

- role: cloud-digitalocean, tags: digitalocean

- role: security, tags: security
- role: ssh_tunneling, tags: ssh_tunneling

Note: The `vpn` role generates Apple profiles with On-Demand Wifi and Cellular if you pass the following variables:

- OnDemandEnabled_WIFI=Y
- OnDemandEnabled_WIFI_EXCLUDE=HomeNet
- OnDemandEnabled_Cellular=Y
