Coders This article presets Django Cookie Cutter as a simple way to build a Django project with less manual coding and the possibility to customize a few things like UI design and database type SQLite MySql or PostgreSQL For newcomers CookieCutter is a command line utility that creates projects from project templates and Django is a leading web framework built by experts using a batteries included concept Thanks for reading Content provided by App Generator What s in the boxUsing the Django Cookie Cutter tool any developer can generate simple Django projects like the ones listed below with customized design and database backends plus minor things like project name and README instructions free Django Soft UI simple Django dashboard with Soft UI design free Django Volt a modern dashboard with Bootstrap design free Django Datta Able open source colorful dashboard How to use itTo use this simple generator a minimal programming kit should be installed in the workstation starting with Python and GIT Python a modern script language used for many types of projectsGIT a command line tool used to download sources from GithubA modern editor like VSCode Atom or even Notepad Once we have all the tools properly installed we can move on and build a Django project Step Install dependencies cookie cutter and GitPython pip install cookiecutter pip install GitPythonThe above command uses PIP the official package manager for Python to install required modules globally in the system The recommended way to install packages is to use a virtual environment that isolates the installation as

deploying WordPress with MySQL on ks cluster USE CASECreate Ansible Playbook to launch AWS EC InstanceCreate Ansible Playbook to configure Docker over those instancesCreate Playbook to configure KS Master KS Worker Nodes on the above created EC Instances using kubeadmLaunch a WordPress and MySQL database connected to it in the respective slavesExpose the WordPress pod and the client able to hit the WordPress IP with its respective port Pre requisite FOR RHEL Controller node should be setup with ansible installation and configuration when controller node is RHELCreate one IAM user having Administrator Access and note down their access key and secret keyCreate one Key pair in pem format on AWS Cloud download it in your local system and transfer it over RHEL through WinSCP STEP Ansible Installation and ConfigurationInstall Ansible on Base OS RHEL configure ansible configuration file To do this use below commands yum install python ypip install ansible yvim etc ansible ansible

Explanation of Source Code We are using pip module to install two packages ーboto amp boto because these packages has the capability to contact to AWS to launch the EC instances ec group module to create Security Group on AWS ec module to launch instance on AWS register keyword will store all the Metadata in a variable called ec so that in future we can parse the required information from it loop which again using one variable which contains one list item keyword we are calling the list values one after another add host module which has the capability to create one dynamic inventory while running the playbook hostname keyword tells the values to store in the dynamic host group wait for module to hold the playbook for few seconds till all the node s SSH service started access key and secret key are stored inside vault files to hide it from other users Go inside the vars folder We have to write entire variables inside this folder We can directly mention variables inside tasks file

Code We need to install kubeadm program on our master node to setup Ks cluster We are installing Docker Kubeadm amp iproute tc packages on our Master Instance service module is used to start the docker amp kubelet service command module to run kubeadm command which will pull all the Docker Images required to run Kubernetes Cluster We need to change our Docker default cgroup to systemd otherwise kubeadm won t be able to setup Ks cluster To do that at first using copy module we are creating one file etc docker daemon json amp putting some content in it Next using command module we are initializing the cluster amp then using shell module we are setting up kubectl command on our Master Node Next using command module I deployed Flannel on the Kubernetes Cluster so that it create the overlay network setup Also the nd command module is used to get the token for the slave node to join the cluster Using register I stored the output of nd command module in a variable called token Now this token variable contain the command that we need to run on slave node so that it joins the master node STEP Write role for Kubernetes SlavesFollowing are the steps which have to include in
