Step 1 :- Let’s make playbook to run install and configure the httpd service , here is a playbook in this I use variable concept to so to make it dynamic.
Now what is ansible? It is simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. Ansible simple allow you to automate, configure and deployed by writing code and using their modules which makes ansible intelligent will do you all tasks in one go without all the hassle that we used to face before by all the things manually.
Playbooks are used to write the code that do your all tasks weather it is automation, configuration or deployment in multiple systems in one go. …
Kubernetes is an opensource workload distribution and orchestration system for servers in a data center that are clustered. It ensures resource availability and accessibility, as well as balanced execution for multiple servers running at the same time.
Kubernetes, as a distributed data processing mechanism, can allow any number of servers of different types to share workloads for a common client at the same time, regardless of their location. Clients are then faced with these workloads as resources. Kubernetes uses this framework to allow the client system to connect to services over the network, transfer data, and receive responses.
Many data points indicate…
To setup up our python interpreter in order to run python code on it, first we have to configure docker in our base O.S .
To configure and launch a docker container, do check out this blog.👇
Now, after we have successfully launched a docker Container, setting up python interpreter on it is very simple. We just have to run one command and that’s it.
Inorder to configure Httpd software on a docker container, first we have to configure docker on our Base O.S. Let’s see how we can configure docker on our Base O.S, in my case ie. Redhat Version 8.
1. Steps to configure and launch a container on docker :
~ Docker Configuration..
• Installing docker is pretty simple, just by running one command we can very easily install docker on our Base O.S .
Rather than writing the same commands repeatedly in order to achieve our purpose, we can automate it. We just have to write all the commands in a script. It will save us a lot of time, as we only have to write a script once and for all. Let us take the example of creating an LVM partition and automate it by writing a python script.
Steps to to followed in the process are :-
1. Attach two hard disk in your virtual machine, instance or on which of the system your want to create LVM. In my case I’m…
In order to make our static partition dynamic so that we can increase or decrease our partition size we have to integrate the concept of LVM with the partitions.
Let’s say you went short on storage in your Hadoop cluster and want to increase your DataNode Storage without hampering your data stored in the DataNodes, what would you do? Well if you know that’s great, but let me show some simple steps by which you can very easily achieve elasticity in your Hadoop Cluster.
By reading the title itself you might have got the trick. Yes, in order to achieve elasticity in Hadoop we need to integrate LVM (Logical Volume Manager) with it.
Let’s see how we can do Web Hosting and create an architecture with high availability by using some of the services of the AWS. Here we are going to know, how to launch and use those different services from our Windows Command Line.
