devops-challange

Provisioned Flask Webapp using Vagrant and Ansible

This repository contains the basics for developing a Flask application within a Vagrant VM, using Ansible for provisioning.

Instructions to follow: To start provisioning, we need to have vagrant installed on local computer or cloud. Basically automated task is only tested on Local setup.

1. clone this below repo:

#git clone https://github.com/manukoli1986/devops-challange.git

2. Boot up your Vagrant environment:

#vagrant up

If you get any error during bootup use any below command

#vagrant up --provision
OR
#vagrant reload --provision

This may take less or more than a minute depending on your internet connection (so be patient).

Once Vagrant is UP and running, you will be seeing below message:

#vagrant up --provision

Vagrant has automatically selected the compatibility mode '2.0'
according to the Ansible version installed (2.7.10).

Alternatively, the compatibility mode can be specified in your Vagrantfile:

3. Our webapp is deployed now lets get connect to it using below IP address. For your case you need to run another command to get your vagrant guest machine's IP.

#curl -s 192.168.0.107:5000

{"headers":{"Accept":"*/*","Host":"192.168.0.107:5000","User-Agent":"curl/7.64.0"},"origin":"192.168.0.101"}



#vagrant ssh -c "hostname -I | cut -d' ' -f2" 2>/dev/null
192.168.0.107

4. Vagrant runs the virtual machine without a UI. To prove that it is running, you can SSH into the machine:

#vagrant ssh
