ansible_aws_demo

A set of playbooks to demo Ansible for AWS. The demo app uses AWS Lambda and DynamoDB.

This demo utilizes Ansible to deploy from zero to all-running state an application in AWS.

Main development is doing in the @common-devel branch.

Structure

There are two directories on top:

• demo_1 - includes ansible playbooks and configuration for deployment of infra
• demoapp - includes source code and playbooks to deploy frontend and backend of app.

Infra

Go to /demo_1 directory. There is a bunch of task files named as task_install-* and task_uninstall-*. Every of them does only a small part of the whole job. These task files are not playbooks and cannot be run separately. (See install.yml for this).

There is a config file vars_aws-vpc.yml which describes the configuration of an infrastrcture for orchestrating.

There is a playbook install.yml which should be run to install and uninstall infra, and, also to install and uninstall the demo application.

Using install.yml playbook

To run this playbook you need to provde aws_secret_key and aws_access_key environment variables. Or they being searched in the file ~/.aws/credentials.

The playbook can be run by following ways:

• install infra: ansible-playbook install.yml -e do=install -e scope=infra

• install demo app: ansible-playbook install.yml -e do=install -e scope=app

• uninstall infra: ansible-playbook install.yml -e do=uninstall -e scope=infra

• uninstall demo app: ansible-playbook install.yml -e do=uninstall -e scope=app

• additionally, you can get credentials to access the deployed infrastructure: ansible-playbook install.yml -e do=install -e scope=infra -t summary

In case if during process do=install an error happens, the playbook automatically runs do=uninstall actions.

Note: So far the demo app can be deployed without provisioning an infrastructure. Up now it has only backend component implemented which works entirely on AWS Lambda functions and AWS DynamoDB.

Deployment

There is a two-step process to get all run.

• deployment of instrastructure
• intalling the demo application

Backend

Implemented on AWS Lambda functions, persistent data is stored in AWS DynamoDB.

Frontend

So far frontend is not ready yet.
