Write a Ansible Adhoc Commands to create a group called “deploy Write a Ansible Adhoc Commands to create a user called “deploy-user” which is part of group called “deploy” and with /bin/bash shell.  Write a Ansible Adhoc commands install package named “httpd” in RHEL/centos. Write a Ansible Adhoc commands to start and enable the service named “httpd” Write a Ansible commands to copy a file called “second.html” in /var/www/html/second.html with some dummy html contents.

What is ansible? Ansible is a server configuration management tool . Benefits of Ansible? Free and open source Easy to learn, deploy and debug. Platform independent. Ansible is Idempotent . Architecture of Ansible

What is Ansible? Ansible is a tool which manages configuration of servers. Management includes hardware and software management of server. Why Ansible? Easy to learn compare to java, python, ruby etc Its platform Independent Ansible has feature – IDEOMPOTENT Its open source tool Architecture of Ansible Ansible communicate with remote servers (ARS) through Ansible Control Server (ACS)

Ansible is a configuration management tool where the server(s) (hardware and software)configurations can be automated. It is owned by RedHat and is open source and is written in python. It is easy to use and can run on any machine (linux or windows) ad helps in managing server(s) configuration management Ansible architecture components: 1.User —>Admin 2. ACS —> Ansible control server—> management node 3. ARS —-> Ansible Remote server (Host 1 ,2 ….n) It has 3 main components of ACS:

What is Ansible? Ansible is a cross-platform Configuration Management Tool for Server(s), which is primarily written using python. Benefits of Ansible The benefits are as follows: It is easy to learn, understand and use which makes it the choice for server config management It is Idempotent, that is, there are no additional effect if it is called more than once with the same input parameters. It is Platform Independent. Ansible-Command prompt is free. Architecture of Ansible

what is ansible? It is a Tool which manage configuration of servers. Configuration of servers includes create/delete/modify file, install/uninstall packages, start/restart services etc.. Benefits of Ansible: Its free open source Tool Easy to learn and use platform independent It works for All OS .like windows, Linux Ansible modules are idempotent Architecture of Ansible: Human communicate with ansible remote servers through Ansible control server. The component Of ACS includes Tool, Ansible inventory, and ansible playbook.

Every Kubernetes cluster is provisioned with a special service that provides a way for internal applications to talk to the API server. by the command kubectl get svc, we can see that service listed with the name ‘kubernates‘

A kubernetes service is a group of pods running in a cluster. ClusterIP is a service which is accessible only within the Kubernetes cluster. Hence, it is the internal IP of the components inside a Kubernetes cluster. NodePort is an open port for every node in the cluster. This is accessible from outside the cluster. LoadBalancer distributes the external request among the workers of the cluster. Following commands are used to create 4 PODS using four Manifest files (pod1.yaml, pod2.yaml,
