When it comes to Kubernetes (K8) security as it is said by most of the reviewers that Kubernetes is insecure by design and the cloud system adds to the adversity. CNCF has provided a few guidelines to give better security practices for Kubernetes. These recommendations are considered to be good for people who are accustomed to using Google’s services.

Kubernetes is an open-source objective that helps in the automation of Linux container operations. Kubernetes works, in simpler terms, by eliminating the manual processes involved in a running group of Linux containers. The deploying and scaling are automated so developers can work more efficiently by managing a clustered group of hosts. One of the main perks of using Kubernetes to host cloud-native applications is that it works with an array of container tools such as Docker. Also, popular cloud services extended a Kubernetes based platform for services. …
New in Ansible 1.5, “Vault” is a feature of ansible that allows keeping sensitive data such as passwords or keys in encrypted files, rather than as plain text in your playbooks or roles. These vault files can then be distributed or placed in source control. To enable this feature, a command line tool, ansible-vault is used to edit files, and a command line flag –ask-vault-pass or –vault-password-file is used. Alternately, you may specify the location of a password file or command Ansible to always prompt for the password in your ansible.cfg file. These options require no command line flag usage.
Ansible is an effective IT computerization tool that is used to program application deployment, cloud provisioning, configuration management, etc. It is specifically designed for multi-tier deployments and models IT infrastructure by defining how system management can be interrelated instead of managing each of them individually. One of the best aspects of this engine is that it doesn’t employ any agents or additional custom security infrastructure making it effortless to deploy. It further uses a simple language that allows the system admin to describe automation tasks in simple English. Ansible, by default, represents the nodes it manages using simple files that…
Why we love Terraform so much? 4 things to know,
We love Terraform because of its many advantages,
1. Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.
2. Execution Plans: Terraform has a “planning” step where it generates an execution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure.
3. Resource Graph: Terraform builds a graph of all…
