Weather App Infra

This repository contains source code related to provisioning infrastructure that will provide weather app services.

Local Development

Terraform

Create a tfvars file

You will need a tfvars file populated with the following variables.

tenant_id       = <tenantid>
subscription_id = <subscription_id>
client_id       = <client_id>
client_secret   = <client_secret>
deploy_pubkey   = <deploy_pubkey>

prefix   = "weather"
location = "West Europe"

Terraform Apply

# assumes you current working directory is terraform
terraform apply --var-file=default.tfvars

If terraform apply fails, check that you have your ssh-agent running, as the connection used relies on the agent to provide authentication.

Terraform will output a file named ansible_hosts_site. This file is the inventory file for ansible.

Terraform Destroy

# assumes you current working directory is terraform
terraform destroy --var-file=default.tfvars

Ansible

Two core playbooks exists at the root level under the ansible directory. The site.yml playbook handles the base configuration for the machine which includes harderning and docker. The weatherapp.yml playbook configures the weatherapp docker containers.

To apply ansible configuration, first copy the ansible_hosts_site to the inventory directory under ansible. Then run the following scripts based on what you want to deploy.

The first playbook you should apply is site.yml which will configure the machine as a docker host.

# assumes you current working directory is ansible
ansible-galaxy install -r requirements.yml
ansible-playbook -i inventory/ansible_hosts_site site.yml

After this, you should apply weatherapp.yml playbook which will configure the docker containers. This playbook requires weatherapp_appid and weatherapp_version to be set.

# assumes you current working directory is ansible
ansible-galaxy install -r requirements.yml
ansible-playbook -i inventory/ansible_hosts_site weatherapp.yml \
            --extra-vars "weatherapp_appid=<appid>" \
            --extra-vars "weatherapp_version=<version>"
