Overview

Using ansible to install and deploy

• clone this repo
• cd into upaas/ansible

Prerequisites

• All servers have ssh access with ssh keys copied to authorized_keys on each server (ansible requirement)
• Ansible has been installed on your local development system

Setup

Change the relevant variables in the setup.sh file. It replaces all vars needed by ansible

I initially used these vars in the inventory files but decided to move them. Feel free to change it.

Execute the convenience script.

./setup.sh

Install dependencies, build deploy and start unikernels

Execute the following playbooks (in the given order)

Setup local environment

ansible-playbook rust.yml -i inventories/local 
ansible-playbook unikernel.yml -i inventories/local 

Setup unikernel ecosystem on each node

ansible-playbook unikernel.yml -i inventories/servers

Ensure load balancers have keepalived installed

ansible-playbook keepalived.yml -i inventories/servers --tags check

Compile and build unikernel of convey load-balancer locally

ansible-playbook load-balancers.yml -i inventories/local --tags fetch-build

Compile and build unikernel of microservices locally

ansible-playbook microservices.yml -i inventories/local --tags fetch-build

Copy and create instances on both worker & load-balancer nodes

ansible-playbook load-balancers.yml -i inventories/servers --tags deploy
ansible-playbook microservices.yml -i inventories/services --tags deploy

Verify using the vrrp ip address (this may vary according to your keepalived.config)

Pipeline script

I have included a simple pipeline script that includes all the ansible playbooks as indicated above

Execute it using the relevant step

./pipeline.sh 1
./pipeline.sh 2
# and so on
