Kubernetes is an open-source platform to deploy, scale, and manage containerized applications or for effective container orchestration. It is used to manage applications built out of multiples of generally self-contained runtimes called containers. Also, it helps companies to manage containerized applications efficiently. Hence, a comprehensive Kubernetes training course can help developers have an upper hand in this open-source platform and get a wide range of career options.
What is Kubernetes and its role in DevOps?
Kubernetes contains commands for the deployment of applications, rolling out changes, scaling of applications and monitoring them; fundamentally automating these operational tasks of container management. Often confused with each other, Kubernetes and Docker are vastly different but they complement each other when used for running containerized applications. Docker lets the user put everything that is needed to run applications into a box that is allowed to be stored and later opened when required. Once the user is boxing up the applications, Kubernetes comes into play and eases the job of managing these applications.
Here are some of the tactical benefits of Kubernetes:
- Automation of operations
Kubernetes allows users to automate daily operations and makes application management efficient. It ensures that applications are running the way they are intended to function.
- Abstraction of infrastructure
Kubernetes handles computing, networking, and storage workloads on behalf of developers which allows them to focus on the applications instead of the backend environment.
- Monitoring the health of services
Kubernetes is known for running health checks on services and restarting containers that end up failing or stalling. It makes services available to users only when it can confirm the status of their successful functioning.
Kubernetes and DevOps complement each other and work together to assist development and make it faster and more effective for corporations that invest in building complex software and applications. With the increasing size of applications and the delivery requirements of these applications getting more fast-paced, software development companies are using DevOps as a solution by introducing this adaptive approach assisted by Kubernetes to IT or software development processes.
Although containers and DevOps differ in concept, they complement each other during application. Kubernetes allows multiple containers to work together which reduces operational load and supports being used from data centers and in a private, public, or hybrid cloud.
Here is how Kubernetes has a role in empowering DevOps processes:
Making stages of developing the software processes and the production environment consistent: It assists in developing, testing, and deploying processes while writing or testing an application that is housed inside a container. This simplifies the responsibilities of individuals involved in the process, such as the people behind development and administration, and the testers.
Offering seamless updates: It allows uninterrupted software delivery which helps in updating a single part of the application by rebooting the container without affecting any other part of the application. Updates are needed consistently and on a streamlined basis especially when an application is segregated across multiple microservices and deployed in different containers.
Allows effortless scalability and supports multiple frameworks: Kubernetes offers an integrated container-based ecosystem that is known to be continuous and autonomous in nature, hence providing the option of scaling up or scaling down the application based on requirements and workload. It also supports many frameworks and host systems that make migration more effective.
Decreases time taken for onboarding new applications: Kubernetes alongside DevOps helps in reducing the time taken to build new projects.
Increases the productivity and efficiency of developers: Kubernetes promotes instant feedback on developer builds while avoiding waiting in pipeline queues which leads to higher productivity and efficiency. Also, this makes it convenient for developers when defining the CI configuration.
Increases efficiency of server usage: When applications are not efficiently packed on the servers, it leads to organizations having to overpay for the extra loads. Kubernetes helps in making server usage more efficient, hence ensuring that there are no unwanted heavy loads.
Top 10 skills in Kubernetes that pay off
Here are the top 10 skills that can be acquired with effective Kubernetes training which can assist developers in working with Kubernetes more effectively,
- Knowing the foundations of Kubernetes
Know about different operating systems, mainly have a good foundation in Linux basics and knowledge of containers. It helps to be well versed with basic Linux commands which are utilized during working with containers.
- Having good knowledge of YAML basics
YAML is a data-serialization language for the human end-user. It is used in Kubernetes for configuring files and in applications where data is being transmitted or stored.
- Having a deep knowledge of Dockers
Having knowledge of Dockers and advanced knowledge of containers is highly essential to promote smooth workloads.
- Management of applications in Kubernetes
Knowing how to use the application package manager is the key to using Kubernetes successfully.
- Deployment of applications
Knowing how to deploy scalable implementations through various open-source methods is necessary to effectively use Kubernetes.
- Deploying a Java microservice on Kubernetes with support for polyglot
Know about Java microservices and how to run applications alongside a polyglot microservice while using routing, services discovery, and registration as leverage.
- Knowing how to debug and log your Kubernetes application
Knowing how to debug and log applications is one of the fundamental skills required for Kubernetes.
- Knowing Kubernetes networking and services
To help automate the deployment and management of any cloud service for the application, Kubernetes Service Catalog and the Open Service Broker API should be learned.
- Knowing the basics of Kubernetes security
Knowing how to secure your workloads and prioritization of the security aspects of the application is rudimentary. And, knowing about these security elements proves to be highly useful.
- Knowing how to use Sysdig Falco and Kubernetes to set up runtime container security monitoring
Knowing how to run Falco on a Kubernetes cluster through the cloud helps in creating artificial security incidents.
With application development becoming the primary focus of many MNCs and organizations, more focus is being laid on systems like Kubernetes which promote effective and efficient development. This area has a lot of potential and developers are getting increasingly more involved with Kubernetes.
