Scripted Deployment

Before you begin, make sure you have installed all the dependencies necessary for your operating system as described in the README.

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:

ansible-playbook main.yml -e "provider=digitalocean
                                server_name=algo
                                ondemand_cellular=false
                                ondemand_wifi=false
                                local_dns=true
                                ssh_tunneling=true
                                windows=false
                                store_cakey=true
                                region=ams3
                                do_token=token"

See below for more information about providers and extra variables

Variables

  • provider - (Required) The provider to use. See possible values below
  • server_name - (Required) Server name. Default: algo
  • ondemand_cellular (Optional) VPN On Demand when connected to cellular networks. Default: false
  • ondemand_wifi - (Optional. See ondemand_wifi_exclude) VPN On Demand when connected to WiFi networks. Default: false
  • ondemand_wifi_exclude (Required if ondemand_wifi set) - WiFi networks to exclude from using the VPN. Comma-separated values
  • local_dns - (Optional) Enable a DNS resolver. Default: false
  • ssh_tunneling - (Optional) Enable SSH tunneling for each user. Default: false
  • windows - (Optional) Enables compatible ciphers and key exchange to support Windows clietns, less secure. Default: false
  • store_cakey - (Optional) Whether or not keep the CA key (required to add users in the future, but less secure). Default: false

If any of those unspecified ansible will ask the user to input

Ansible roles

Roles can be activated by specifying an extra variable provider

Cloud roles:

  • role: cloud-digitalocean, provider: digitalocean
  • role: cloud-ec2, provider: ec2
  • role: cloud-vultr, provider: vultr
  • role: cloud-gce, provider: gce
  • role: cloud-azure, provider: azure
  • role: cloud-scaleway, provider: scaleway
  • role: cloud-openstack, provider: openstack

Server roles:

  • role: vpn
  • role: dns_adblocking
  • role: dns_encryption
  • role: ssh_tunneling
  • role: wireguard

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

  • ondemand_wifi: true
  • ondemand_wifi_exclude: HomeNet,OfficeWifi
  • ondemand_cellular: true

Local Installation

  • role: local, provider: local

Required variables:

  • server - IP address of your server
  • ca_password - Password for the private CA key

Note that by default, the iptables rules on your existing server will be overwritten. If you don't want to overwrite the iptables rules, you can use the --skip-tags iptables flag.
