Installing the System

Requirements

• Memory: 2 GiB of memory is a tight minimum
• Storage: 2.5 GiB of storage is a very tight minimum, 8 GiB is comfortable

Procedure

To install the Unified Communication use case in an all-in-one setup, do the following steps:

1. Install a Debian 10 Buster system with a default locale with an UTF-8 charset.

2. Run the following commands as root on the Debian system to provision sudo, git and Ansible:

   apt update
   apt install -yq sudo git ansible curl

3. Extract the Wazo Platform installer

   git clone https://github.com/wazo-platform/wazo-ansible.git
   cd wazo-ansible

4. (optional) By default, Wazo Platform will install the development version. To install the latest stable version

   ansible_tag=wazo-$(curl https://mirror.wazo.community/version/stable)
   git checkout $ansible_tag

5. Install the Wazo Platform installer dependency

   ansible-galaxy install -r requirements-postgresql.yml

6. Edit the Ansible inventory in inventories/uc-engine to add your preferences and passwords. The various variables that can be customized are described at https://github.com/wazo-platform/wazo-ansible/blob/master/README.md#variables.

   By default, Wazo Platform will install the development version. To install the latest stable version, activate the following settings in your inventory:

   [uc_engine:vars]
   wazo_distribution = pelican-buster
   wazo_distribution_upgrade = pelican-buster

   If you want to install the web user interface, activate the following in your inventory:

   [uc_ui:children]
   uc_engine_host

   To create the root account at installation time and be able to use the web user interface and REST APIs, you need to add the following variables:

   [uc_engine:vars]
   engine_api_configure_wizard = true
   engine_api_root_password = ****

7. Launch the installation by running the following command:

   ansible-playbook -i inventories/uc-engine uc-engine.yml

Use the REST API

You may now use the REST API from outside your system (here wazo.example.com).

1. Get an authentication token for 1 hour:

   Using the api_client_name and api_client_password you defined in your inventory, you can execute from the Debian system:

   wazo-auth-cli token create --auth-user <api_client_name> --auth-password <api_client_password>

   Or with curl from anywhere:

   curl -k -X POST -u <api_client_name>:<api_client_password> -H 'Content-Type: application/json' -d '{"expiration": 3600}' https://wazo.example.com/api/auth/0.1/token

2. Use any REST API you want, for example, to list the telephony users configured on the system:

   Note: You should replace the following values:

   • my-token with the authentication token

   curl -k -X GET -H 'X-Auth-Token: <my-token>' -H 'Content-Type: application/json' -d '{"firstname": "user1"}' https://wazo.example.com/api/confd/1.1/users

   Note: the token that you have now only has permissions for configuration REST API (wazo-confd).
