Vagrant is a tool for building and managing virtual machine environment in a single workflow.Lowers development setup time.
Ansible is a configuration management tool used for automating provision,configuration and management of IT processes.
TASKS:
Requirements
- Vagrant software
- Oracle virtual box
- Have python installed
- Ansible installed correctly
- GIT bash preferrably
After everything is installed on the terminal,here are the commands to enable ubuntu/binoc64 run inside your vagant machine
Create a directory for the application
mkdir appsample
cd appsample
vagrant init
Vagrant init creats a vagrantfile wheres Vagrant box list installs the required vagrantbox in the system
vagrant box list ubuntu/bionic64
Vagrantfile should have this next line to enable provision later on ansible when we run vagrant provision
ansible.playbook = "playbook.yml"
end
Vagrant up
Installing flask on the env,creating app.py files then running the file
pip install flask
flask run
To make our webapp dynamic,l added routes to the app.py file indicating the python version,date and type of operating system used.
Points to note:
Ansible does indicate compatibility issues when using windows.https://youtu.be/4sMFybv74Uo
Enable the Linux subsytem on the windows platfrom via either the powershell or settings tab.Commands used:
Enable-WindowsOptionalFeature-Online -Featurename Microsoft-Windows-Subsystem-Linux
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get install ansible
ansible --version
Webservers and loadbalancers running Nginx Helps in performance problem,this way we can add new servers (vm's) and increase the capacity of your platform. Distributing the load over multiple machines is referred to as "load balancing".
Virtual box with name loadbalancer already exists.
removing load from the vagrant file then doing vagrant up solved the error.
