Deploy with Ansible

Deployment - Ansible

Minimal Requirements

• Ansible

Ansible scripts are written for the Ubuntu 16.04 or higher

To install ansible with brew:

$ brew install ansible

Check the ansible version:

$ ansible --version
ansible 2.15.4

What is installed and deployed:

Ansible enables the automation of the installation and configuration of the various stack components: All components are dockerised

• Docker

• Postgres

• Certbot to generate and renew ssl certificate

• The node backend

• The frontend packaged inside an nginx container

Configuration

The configuration depends on the phase on the system: dev, prod, uat etc ... Each phase has its own directory which contains the configuration files and the inventory of the remote machines.

The global configuration which is independent on the phase is at group_vars/all/vars.yml

To set the production configuration parameters, create group_vars/production.yml:

Then to change the remote machine connection settings (ip address, username, ssh key location), edit the production inventory: production.ini:

Copy the file vault example to a file called vault.yml

The strict necessary is the docker configuration.

Please create a new access token from https://hub.docker.com/settings/security for docker_hub_password
